Nantong, Sigenergy Smart Energy Centre Launch: PSW Represents Western Australia

PSW Energy and Perth Solar Warehouse Represent Western Australia at Sigenergy’s Nantong Smart Energy Centre Launch

On 13 March 2026, our team represented Western Australia at one of the most significant events in the global clean energy calendar: the official inauguration of the Sigenergy Smart Energy Centre in Nantong, China. PSW Energy and Perth Solar Warehouse were among the select group of installation partners, globally, invited to attend.

Not just a corporate milestone in passing. It is a moment that speaks to the culture we have earned within this business: the commitment every member of our team brings to delivering exceptional work, day after day, system after system. 

The Sigenergy Smart Energy Centre

The Sigenergy Smart Energy Centre is not a conventional factory; it is a purpose-built hub combining advanced R&D, intelligent manufacturing, global delivery, and energy management under a single roof. Covering 136,000 square metres and totalling RMB 500 million (approximately AUD $110 million), the facility has an annual production capacity of more than 300,000 inverters and battery packs.

The numbers behind this facility are extraordinary. Automated welding with CCD visual inspection delivers a 99.9% yield rate. Surface-Mount Technology lines process components at a rate of 0.043 per unit per second. The facility produces one battery pack every 15 seconds and one inverter every 21 seconds. This is the manufacturing backbone that will supply PSW Energy and Perth Solar Warehouse with Sigenergy products well into the future, at scale, with uncompromised quality. 

The “AI in All” Strategy

At the launch event, Sigenergy’s founder and CEO, Tony Xu, introduced the company’s defining next chapter: an “AI in All” development strategy. Far from being a marketing phrase, this approach embeds artificial intelligence at every layer of Sigenergy’s business, from product design to system operation, energy dispatch, and user experience. 

Tony Xu put it directly at the ceremony: “In the new energy sector, we never follow trends or compete on scale. Instead, we embed AI into the core of energy systems, transforming them from merely ‘functional’ to ‘intelligent, collaborative, and evolving.’” 

For our customers in Western Australia, this translates into Sigenergy systems that will continue to get smarter over time — optimising energy management, adapting to grid changes, and improving performance through software and AI without requiring hardware replacement. 

New Products Announced at the Event

Alongside the facility launch, Sigenergy unveiled a new generation of products spanning residential, commercial and industrial, and utility-scale applications: 

  • SigenStor Neo — an evolved home energy system with enhanced AI integration, improved home scenario adaptability, and the iconic modular architecture that has made SigenStor one of the most installed residential battery systems in Western Australia.
  • 166 kW C&I PV Inverter — a new commercial and industrial inverter designed for higher power density and simplified solar-plus-storage integration for business customers.
  • 500 kW Utility Inverter — a grid-scale solution supporting 1650 V DC input and 1000 V AC systems, designed to reduce system costs while improving energy yield across large solar power plants.

As an inaugural Sigenergy Gold Installer, PSW Energy and Perth Solar Warehouse are well-positioned to bring these next-generation products to Western Australian customers as they reach Australian certification and availability. 

Why Our Invitation Matters

Attendance at the Nantong launch was not open to the general industry. Sigenergy specifically extended invitations to founders, CEOs, and senior executives from its most trusted distribution and installation partners worldwide. The nearly 2,000 guests in attendance represented more than 50 countries and regions, the full breadth of Sigenergy’s global installer network.

PSW Energy and Perth Solar Warehouse were invited to that community because we hold Sigenergy Gold Installer status, the highest non-exclusive installer tier in Sigenergy’s certification program, and one held by very few businesses in Australia. Our inclusion in this event alongside global industry leaders reflects the strength of the relationship we have built with Sigenergy since becoming inaugural Sigenergy-certified installers in Western Australia. 

Sigenergy Gold Installer is the highest non-exclusive certification tier in Sigenergy’s global installer program. PSW is among a select number of Australian businesses to hold this status.

Our journey with Sigenergy in Western Australia began before SigenStor was a household name in the local market. We believed in the product early, invested in the training and technical capability to install it correctly, and built a track record of installations that now speaks for itself. Being invited to Nantong is a natural extension of that history. 

To Our Team: This Is Your Achievement

Every installation our electricians complete, every service call our technical team handles, every customer conversation our sales and support staff have, all of that underpins the reputation that earned us a seat at the table in Nantong.

We operate from Bibra Lake and Neerabup, with crews working across greater Perth and the South West. The Sigenergy Gold certification that brought us to this global event is not held by the directors; it belongs to the 50+ people across our business who execute the work to the standard that makes our credentials real.

Take a moment to let that land. While other installers were reading about this event in trade publications, we were in the room. 

50+ employees across Bibra Lake and Neerabup. One of the inaugural Sigenergy Gold Installers in Western Australia. Invited to Nantong among partners from 50+ countries. This is what a high-performance culture produces. 

What This Means for Our Customers and Our Future

The Nantong Smart Energy Centre launch is not just a symbolic milestone for Sigenergy; it is an investment in supply chain reliability and product quality that directly benefits our customers. With annual production capacity exceeding 300,000 inverters and battery packs from a state-of-the-art facility, the supply certainty our customers need for SigenStor installations is backed by genuine manufacturing scale.

The introduction of the SigenStor Neo and Sigenergy’s “AI in All” strategy also signals where home energy storage is heading. The next generation of systems will not just store energy, they will learn, adapt, and coordinate. PSW Energy and Perth Solar Warehouse are positioning now to bring this technology to Western Australian homes and businesses as it becomes available through Australian regulatory channels.

We are committed to continuing to invest in our people, our technical training, and our manufacturer relationships so that the quality of our installations and the partnerships behind our products remains at the level that belongs in a room with 2,000 global industry leaders.

Powerwall 2 and Powerwall 3 are coming to the same roof

A forthcoming firmware release from Tesla will enable the combined operation of Powerwall 2, Powerwall 3, and Powerwall 3 Expansion units, opening a meaningful new upgrade pathway for existing customers and a new sales angle for our teams.

  • KEY DATE
    Tesla has confirmed to installers that the cross-compatibility firmware update is targeted for June 2026. Commissioning guidelines, app notes, and updated installation manuals will be released closer to launch. No hardware retrofit is required.

Until now, Powerwall 2 and Powerwall 3 have operated as entirely separate product lines. A homeowner with an existing Powerwall 2 installation who wanted to add more battery capacity faced a constrained choice set. That changes with this update.

Tesla has advised installers that a future firmware release will enable combined operation across all current Powerwall variants. The change is delivered entirely through software, with no hardware retrofit required for existing Powerwall 2 systems, a meaningful detail for homeowners concerned about compliance or disruption to their installations.

What the supported configurations look like

The update will support mixed systems of up to the following unit counts, in any combination:

POWERWALL 2

4x

units per system

POWERWALL 3

1x

unit per system

PW3 EXPANSION

3x

units per system

This creates considerable flexibility in how customers can grow an existing Powerwall 2 installation. A home already running two Powerwall 2 units, for example, could add a Powerwall 3 and up to three Expansion units, bringing total system capacity well beyond what was previously achievable in a single gateway installation.

Compliance and certification: the important nuance

Tesla has been clear on a distinction that matters for installers and customers alike: existing Powerwall 2 installations remain fully compliant, even where CEC listings have expired. The compliance requirement applies only to newly installed Powerwall 3 equipment, which must meet current certification standards at the time of installation.

This removes a potential concern for homeowners who might otherwise have assumed their older installation would need to be brought up to current certification before they could expand it.

Three-phase installations: When installing on a three-phase grid connection, Powerwall 3 output will be limited to 5 kW. This is a known constraint and should be factored into system design and customer conversations at the proposal stage until the 3-phase native Powerwall 3 becomes available in Australia.

Compatibility exclusions to be aware of

The following legacy hardware is not supported under the new configuration:

  • Gateway 1
  • Neurio Meter

Customers with these legacy components will need assessment prior to any upgrade conversation. As part of our pre-sale process, our teams should confirm gateway generation before presenting cross-gen configurations.

PSW Energy · Perth Solar Warehouse — Installer perspective

As Perth’s leading Tesla Premium Certified installer, PSW Energy and Perth Solar Warehouse are well-positioned to support customers through this upgrade pathway from day one.

Our existing Powerwall 2 customer base represents a ready pipeline. Teams can begin conversations now: Tesla has confirmed that sharing this upcoming capability with Powerwall 2 customers ahead of the firmware release is appropriate. The message is straightforward: their existing system is compliant, nothing needs to be replaced, and when the update lands in June, adding a Powerwall 3 becomes a live option.

Detailed commissioning guidelines and updated installation manuals will be released by Tesla closer to launch. Both locations, Bibra Lake and Neerabup, will be briefed ahead of the rollout. Customer-facing materials for both brands will be updated to reflect the new configurations once Tesla’s official documentation is available.

This post is based on installer communications received from Tesla Energy ahead of the firmware release. Technical specifications, supported configurations, and compliance guidance are subject to change. Final details will be confirmed when Tesla releases official commissioning documentation closer to the June 2026 launch.

7 Years Strong: The PSW x Tesla Energy Partnership

Tesla Premium Certified Installer 2026 Perth Solar Warehouse (2)

The collaborative Perth-region Duo, PSW Energy and Perth Solar Warehouse, has been recognised as a Tesla Premium Certified Installer for the fifth consecutive year. For McKercher Corporation, this milestone marks an evolving partnership between two organisations aligned on a shared objective: accelerating sustainable energy adoption through quality local implementation.

Contents

This post provides McKercher Corporation staff and stakeholders with a comprehensive account of how the relationship has developed, what it means operationally, and why this collaboration remains central to the organisation’s strategic positioning in Western Australia’s energy market.

Certification: 2026, Perth Solar Warehouse ›

Origins

Certified installer to strategic partner. Perth Solar Warehouse entered the Tesla Energy Certified Installer network in 2019. The early years (2020–2021) established operational foundations: training, compliance, and product familiarisation within Tesla’s structured onboarding framework.

By 2022, Tesla elevated Perth Solar Warehouse to Premium Certified Installer status, a distinction awarded to the top 5% of Tesla’s certified installer network in Australia. Premium Certified status introduced mandatory project-level auditing, where every installation is documented and remotely assessed against Tesla’s internal quality benchmarks. In 2023, Perth Solar Warehouse scored 95% across all jobs assessed under this framework.

The distinction matters. Standard certified installers are authorised to sell and install Tesla products. Premium Certified Installers operate under continuous performance monitoring, maintain access to priority product allocation, and are positioned by Tesla as its most trusted brand partners. There are currently only four Tesla Premium Certified Powerwall Installers in Western Australia. PSW Energy, Perth Solar Warehouse is one of them.

Premium Certified status earned and retained

Tesla reassesses Premium Certified status annually. It is never guaranteed, regardless of prior performance. PSW Energy, Perth Solar Warehouse must consistently demonstrate alignment across five criteria:

  • Exceptional installation quality — Every installation is submitted for Tesla's remote assessment and ranked against standardised benchmarks, creating an ongoing quality scorecard that directly informs certification decisions.
  • Deep product knowledge — Staff maintain current proficiency across the full Tesla Energy product suite (Powerwall 3, Gateway, Wall Connector, Tesla app ecosystem). Training requirements evolve with each product release.
  • Distinguished customer experience — Tesla independently monitors customer satisfaction. Perth Solar Warehouse has maintained a 4.8 out of 5 rating across Tesla's internal audit process, assessed beyond the point of sale through the full lifecycle from consultation to aftercare.
  • Longevity and depth of relationship — Seven years of collaboration and five consecutive years at Premium Certified level represent sustained bilateral investment, not short-term performance spikes.
  • Alignment with Tesla's mission — Tesla's mission to accelerate the world's transition to sustainable energy is directly paralleled by McKercher Corporation's focus on improving sustainable energy adoption through digitalisation and customer-centric implementation.

Shared milestone timeline

2019: Perth Solar Warehouse enters the Tesla Energy Certified Installer network.

2020–2021: Two years as a Tesla Certified Installer. Staff complete foundational training and compliance frameworks. Operational workflows for Tesla product installations are embedded across sales, applications, projects, and aftercare teams.

2022: Elevated to Tesla Premium Certified Installer (top 5% nationally). Mandatory project-level auditing begins.

2023: Premium Certified retained. Perth Solar Warehouse scores 95% across all Tesla-assessed installations. Tesla’s internal review shows 362% year-over-year growth in Powerwall sales in Q4. In November, Perth Solar Warehouse co-hosts the inaugural Tesla Energy Tech Talk at the Tesla Motors Showroom in Osborne Park. RSVP capacity is exhausted within 48 hours. McKercher Corporation Director Derek McKercher presents as a guest speaker.

2024: Premium Certified retained. Perth Solar Warehouse receives the Tesla Energy Performance Excellence Award for Q4 2023, one of only three awards issued nationally that quarter. Derek McKercher returns as keynote speaker for the second Tesla Energy Tech Talk in February. In August, Perth Solar Warehouse is represented among the top 5% of Australian Tesla Certified Installers at the national Powerwall 3 launch event in Sydney. In September, Perth Solar Warehouse receives the first Tesla Powerwall 3 unit in Western Australia. A third Tech Talk is held at the Tesla Showroom in O’Connor in December.

2025: Premium Certified retained for a fourth consecutive year. Perth Solar Warehouse consolidates its position as one of four Tesla Premium Certified Powerwall Installers in Western Australia.

2026: Premium Certified retained for a fifth consecutive year. Seven years of combined Tesla Energy collaboration.

Staff Takeaway

The Tesla Energy relationship touches every department involved in Tesla product delivery. Sales and administration teams operate within Tesla’s Partner Portal and maintain the product knowledge standards Tesla audits. Applications and projects teams manage documentation and submission workflows feeding Tesla’s remote assessment process. Installation teams follow Tesla’s protocols, with every job contributing to the quality scorecard. Aftercare teams manage the post-installation experience that Tesla independently monitors.

The 4.8/5 satisfaction rating, 95% audit scores, and five consecutive years of Premium Certified recognition are collective achievements — the direct output of every team within Perth Solar Warehouse contributing to a standard Tesla reassesses annually.

As McKercher Corporation Director Derek McKercher noted: “A direct relationship over an enduring period has allowed PSW to assist Tesla’s mission towards broader adoption of sustainable energy products for more. Customers prefer fewer layers of complexity, especially where warranty concerns arise.”

What this means for customers

For homeowners engaging Perth Solar Warehouse for Tesla products, Premium Certified status provides specific assurances:

  • Manufacturer-backed quality verification: Every Tesla installation undergoes Tesla's internal auditing process. Standard certified installers are not held to this standard.
  • Enhanced warranty confidence: Tesla product warranties require installations to meet Tesla's strict standards. Premium Certified Installers operate under the highest level of manufacturer-verified compliance.
  • Priority product access: Perth Solar Warehouse receives priority allocation for new Tesla products. This is how the team received the first Powerwall 3 in Western Australia and represented at the national launch.
  • Local expertise with manufacturer alignment: Seven years of Tesla Energy experience combined with detailed understanding of Western Australian energy regulations, Western Power grid requirements, and state-specific compliance.
  • Continuity and accountability: Backed by McKercher Corporation's 20-year business history in energy services, Perth Solar Warehouse offers long-term local presence that extends support well beyond the point of sale.

The year ahead

The partnership enters 2026 with established momentum. The relationship has evolved from a standard commercial arrangement into a strategic collaboration defined by co-hosted events, shared performance metrics, product launch participation, and mutual investment in customer outcomes.

McKercher Corporation views this partnership as a model for how manufacturer–installer relationships should function: built on transparency, sustained performance, and a shared commitment to enabling broader energy independence for Australian households.

2025 SolarNerds annual industry review: PSW Energy, Western Australia

McKercher Corporation acknowledges the latest independent industry benchmarking from SolarNerds.com.au (2025 Awards Edition), which ranks PSW Energy (including Perth Solar Warehouse volume) among Western Australia’s top-performing installation companies in both rooftop solar and home batteries.

PSW Energy
Category
Volume
Market Share
2nd
Battery
10,398 kWh
3.06%
4th
Solar
6,128 kW
2.27 %
In the Western Australia (WA) solar retailer leaderboard for systems up to 100 kW, PSW ranked 4th in installed capacity in 2025, delivering a total of 6,128 kW across 724 systems, corresponding to a reported market share of 2.27%. In the battery storage sector, PSW ranked 2nd in WA, supplying 10,398 kWh across 673 systems, for a reported market share of 3.06%.
This recognition is significant because Western Australia’s market is both mature and highly competitive. According to the Solar Nerds report, WA installed a total of 269,913 kW of solar power across 30,678 systems in 2025, with 79.8% of this capacity coming from residential systems in the 0–15 kW segment. On the battery front, WA recorded 339,587 kWh across 19,192 systems, with an average installed battery size of 17.69 kWh. In this context, achieving a top-tier position indicates consistent delivery at scale, rather than just a single project or a temporary surge.
From a corporate standpoint, these outcomes highlight three core strengths we anticipate from the McKercher Corporation’s operational business: (1) consistent field execution, (2) a disciplined approach to system design and commissioning, and (3) a customer experience that remains reliable across numerous deployments. As a result, practical trust is fostered: families and businesses are more inclined to choose an installer that exhibits capability, consistency, and longevity, based on independently collected data.
Solar Nerds’ statistics are derived from the Clean Energy Regulator REC Registry and are based on STC registration data for systems up to 100kW; the report notes that installation dates can lag registration and may vary by up to 12 months. We see this methodology as a useful, standardised way to compare relative delivery performance across the sector using a common dataset.
Recognition at this level relies on the contributions of many individuals. It results from the hard work of electricians, apprentices, designers, schedulers, warehouse teams, customer service staff, and leaders who consistently execute the fundamentals well—day in and day out, across numerous projects. As McKercher Corporation continues to enhance its capabilities in electrification and distributed energy, we see these results as confirmation that PSW can foster long-term career opportunities in a growing segment of the Western Australian economy.

Customer Service Platform Upgrade, 24–31 January 2026

McKercher Corporation is undergoing a significant upgrade in how we manage customer inquiries, projects, and support. Over the Australia Day period, we will be transitioning from our existing Customer Management System to a new, enhanced platform designed to improve service speed, visibility, and consistency.

This update is relevant to two key audiences: our customers, who depend on us for timely support and clear communication, and our internal team, who will navigate this change while continuing to deliver excellent service. Our goal is simple: to set clear expectations for the short term and outline the tangible improvements you can expect once the new platform is live.

Migration timeline

The migration window is scheduled across the Australia Day period, from Saturday 24 January to Monday 26 January 2026. (Australia Day is observed on Monday, 26 January 2026; our migration window spans the public holiday period to reduce disruption to normal business operations.)

Following the technical migration, staff inductions and familiarisation will continue through to Friday, 30 January 2026. During this phase, we will actively bed down workflows, confirm data integrity, and ensure every team member is confident in using the new tools.

What to expect during the transition

We are planning carefully to minimise disruption, but some interruptions may occur during two distinct periods:

1. Technical migration period: 24–26 January 2026. During the cutover, some services may be intermittently unavailable or slower than usual. This can include delays in our ability to:

  • Retrieve account history quickly (quotes, job notes, previous correspondence)

  • Respond to enquiries at our usual turnaround time

  • Provide real-time updates while data is being synchronised

2. Staff familiarisation period: 27–31 January 2026. As our team completes inductions and transitions day-to-day work into the new platform, you may notice:

  • Slightly longer response times for non-urgent enquiries

  • Extra verification questions (to confirm details while we refine new dashboards and workflows)

  • Minor process changes in how we log, track, and close requests

We recognise that even small delays can be inconvenient. We are being transparent because clear expectations protect customer trust and support our team to deliver consistent outcomes during change.

Why we are doing this

This migration is a strategic investment in customer service excellence, predominantly for PSW brands (PSW Energy and Perth Solar Warehouse). Our existing systems have served us well, but they have limitations: fragmented information, manual handovers, and reduced visibility across teams can slow responses and make it harder to deliver the level of service consistency we want to be known for.

The new platform is designed to remove those bottlenecks and improve the customer experience in practical, measurable ways.

What improves for customers and staff

Faster response times for customer enquiries. By consolidating customer information into a single platform and improving internal routing, our team will be able to locate job details, history, and next steps more quickly. This reduces time spent searching across systems and increases time spent solving the actual issue.

Integrated chat support for real-time assistance. Where appropriate, customers will be able to use integrated chat to get faster answers to simple questions, receive updates, or get triaged. For staff, this creates a clearer context, better continuity, and fewer missed handovers.

Personalised dashboards tailored to individual customer needs (G2). Customers and internal teams will benefit from dashboards that present the most relevant information upfront—job progress, key milestones, required actions, and service notes—reducing back-and-forth and improving clarity.

Enhanced reporting capabilities for better insights. Better reporting improves decision-making. It will help us identify response-time trends, recurring issues, workload peaks, and service improvements with far greater accuracy. Internally, that means we can proactively fix problems rather than react to them.

Better data security to protect customer information. The new platform includes strengthened security measures and more robust access controls. This supports safer handling of customer data and clearer accountability across the organisation, aligning with the business’s Cybersecurity and Personal Data Management Policy.

Improved user interface for easier navigation and usability. For staff, usability matters: a cleaner interface reduces errors, improves speed, and supports consistent customer outcomes. For customers, it helps make interactions smoother and more intuitive.

Managing risk and maintaining service standards

We are approaching the migration with a “service-first” mindset. This involves carefully validating data in stages, conducting internal checks to ensure the integrity of customer records, and implementing structured inductions to promote consistent usage across teams.

If anything seems off during the transition—such as missing details, delayed updates, or issues with how requests are being handled—we want to be informed right away. This will allow us to address the problem promptly and enhance the process immediately.

Guidance during 24–31 January 2026

For customers:

  • If your matter is urgent, please contact us using your usual direct channel, and clearly mark the request as urgent so it can be prioritised.

  • If your request is non-urgent, you may experience a slightly longer turnaround during the transition window. We appreciate your patience and will respond as promptly as possible.

  • If you are expecting a specific update (quote, scheduling confirmation, documentation), please allow extra time across 24–31 January 2026.

For staff:

  • Follow the new workflow guidance during the induction period, even if it feels slower initially—consistency early is what drives speed and reliability later.

  • Escalate issues as soon as they are identified. Early reporting improves outcomes for customers and reduces repeat problems.

  • Keep customer communication clear and proactive. If a delay is likely, set expectations early and confirm next steps.

Our commitment

McKercher Corporation is committed to delivering reliable, professional customer service—especially when we are upgrading the very systems that support it. This migration is not a change for its own sake; it is a deliberate step to make service faster, more transparent, and more dependable.

Thank you for your patience across 24–31 January 2026. We will share updates as the migration progresses and will continue focusing on what matters most: clear communication, secure handling of information, and excellent customer outcomes.

Strengthening Trust Through Security With a Unified Cybersecurity and Data Protection Commitment

At McKercher Corporation, protecting our customers’ information is fundamental to our business practices. As energy and solar services become increasingly digital, so too does the responsibility to safeguard personal data and critical systems. That’s why we are proud to announce the successful integration of a unified Cybersecurity and Personal Data Management Policy across PSW Energy and Perth Solar Warehouse—a significant milestone in our ongoing commitment to security, privacy, and transparency.

Contents

Key points

  • Unified, high-standard protection across the group: PSW Energy and Perth Solar Warehouse now operate under a single, executive-approved cybersecurity and personal data management framework, ensuring consistent, strong safeguards for customer information across all services.
  • Clear, customer-focused data security commitments: The policy delivers practical protections—such as encrypted data, strict access controls, rapid incident response, and respect for customer privacy rights—designed to keep personal and energy data secure, transparent, and responsibly managed.

Why This Matters for Customers

For customers, data security is not just an abstract idea; it’s about having confidence. It means knowing that personal details, billing information, and energy usage data are handled carefully, protected from misuse, and managed responsibly throughout their lifecycle. By bringing together PSW Energy and Perth Solar Warehouse under a single, comprehensive policy approved by executive management, McKercher Corporation has set consistent high standards across its entire portfolio.

This integration ensures that whether you are installing solar systems, managing energy services, or interacting with us online, you will benefit from the same strong protections every time.

What the Integrated Policy Delivers

Our unified policy is grounded in clear, customer-focused principles: collecting only the information we need, using it for legitimate purposes, maintaining its accuracy, and retaining it only as long as necessary. Concrete safeguards support these principles to effectively protect our customers. Some key commitments include:

  • Strong access controls so only authorised staff can access sensitive information, using role-based permissions and multi-factor authentication.

  • Encryption of data, both when it’s stored and when it’s transmitted, helps protect information even if systems are targeted.

  • Clear data classification rules that apply the highest level of protection to payment details, account numbers, and energy system data.

  • Regular reviews and audits, including security testing and annual policy reviews, are conducted to ensure that protections remain effective as technology and risks evolve.

  • Mandatory staff training, ensuring employees and contractors understand how to handle customer data securely and recognise potential threats such as phishing.

These measures are not theoretical. They are embedded into daily operations, from how smart meter data is collected and stored, to how billing systems are protected, to how access is immediately revoked when roles change.

How This Protects Customers in Real Life

Imagine reviewing your energy usage or updating payment details online. Under this policy, information is transmitted through secure, encrypted connections, stored in protected systems, and accessed only by staff who genuinely need it to perform their job duties. If a third-party service provider is involved, they must meet the exact rigorous security expectations and contractual obligations.

And if something does go wrong? McKercher Corporation’s PSW Energy and Perth Solar Warehouse have a formal incident response plan aligned with recognised international best practices. Potential incidents are detected, contained, investigated, and resolved quickly. Where personal data is affected, customers and regulators are notified promptly, with clear guidance and support.

Transparency and Customer Rights

Transparency is just as important as security. Customers have the right to know what data we hold, why we retain it, and how they can exercise their rights, such as accessing, correcting, or requesting the deletion of their personal information when appropriate. Our integrated approach guarantees that these rights are consistently upheld across both PSW Energy and Perth Solar Warehouse.

The integration of this policy is not a finish line; it’s a foundation. Cybersecurity and privacy are ongoing commitments, and McKercher Corporation’s brands will continue to review, improve, and invest in protections that keep pace with change.

For prospective and existing customers alike, this unified policy reflects who we are: a forward-thinking sustainable energy group that takes responsibility for safeguarding trust, data, and the systems that support modern energy solutions.

Technical documentation alignment: Consistent datasheet links, one-click downloads, and uniform formatting across all panel and storage families.

PSW Energy & Perth Solar Warehouse Adopt Australian-Made Tindo Solar Panels

McKercher Corporation is pleased to announce that PSW Energy and Perth Solar Warehouse have officially adopted Tindo Solar panels, which are the only photovoltaic modules manufactured in Australia. This strategic decision represents a significant milestone in advancing Australia’s renewable energy landscape. It reinforces both companies’ commitment to supporting local manufacturing, strengthening domestic supply chains, and providing high-quality solar technology to Australian consumers.

Contents

As global supply chains face increasing uncertainty, the integration of Tindo Solar panels represents a conscious shift toward greater energy independence and local capability. For PSW Energy and Perth Solar Warehouse, the move underscores a shared commitment: empower customers with products built for Australian conditions while contributing to the long-term resilience of the national renewable energy industry.

“Adopting Tindo Solar is more than a product decision—it’s a strategic commitment to Australian innovation,” said Derek McKercher for PSW Energy. “Our customers value quality and transparency. Offering Australia-made panels enhances both, while supporting a strong and sustainable local manufacturing sector.”

A Vote of Confidence in Local Manufacturing Excellence

Tindo Solar holds a unique position in the Australian market as the nation’s only manufacturer of solar panels, producing modules at its state-of-the-art facility in Adelaide. With a reputation for stringent quality control, premium component selection, and engineering that meets the demands of Australia’s harsh climate, the company has established itself as a leader in domestic solar technology.

“It was an absolute pleasure showing you around Tindo [PSW Energy and Perth Solar Warehouse]. We look forward to a strong mutually beneficial partnership,” said Director Glenn Morelli from Tindo Solar on LinkedIn. 

Enhanced Value

PSW Energy and Perth Solar Warehouse customers and partners, this development signals increased accessibility to locally produced panels with shorter lead times, more transparent supply chains, and consistent quality assurance. For residential and commercial customers, the alignment between these organisations offers tangible benefits:

  • Access to premium, Australian-engineered solar modules
  • Improved product traceability and local warranty support
  • Confidence that their investment contributes to domestic jobs and manufacturing growth

“Our customers increasingly ask for Australian-made options,” noted Nicole Bilman, PSW Energy, General Manager. “By adding Tindo Solar to our range, we’re delivering a solution that aligns with customer expectations while supporting long-term industry sustainability.”

Strengthening Australia’s Renewable Energy Future

The integration of Tindo Solar panels into PSW Energy and Perth Solar Warehouse’s offerings highlights a shared vision: a stronger, more self-reliant Australian solar industry built on quality, innovation, and local capability. This partnership not only broadens consumer choice but also contributes to the long-term stability of Australia’s renewable energy supply chain.

As demand for reliable and localised energy solutions continues to rise, this collaboration sets an important precedent for industry alignment and domestic manufacturing support.

PSW Energy Refines Installation Timeframes Strengthening Quality and Compliance

PSW Energy (including Perth Solar Warehouse), a prominent solar and battery provider in Western Australia and a subsidiary of McKercher Corporation, has announced an updated scheduling framework for selected installation projects. This enhancement will reinforce the company’s enduring commitment to quality, safety, and compliance with Australian Standards in all system installations.

Contents

The revised time allocations will impact less than 5% of scheduled solar and battery installations, ensuring minimal disruption while allowing for improved planning and precision on more complex projects.

Proactive Quality Assurance

The adjustments are the result of an intentional, forward-looking quality improvement initiative, rather than operational constraints. Installations involving gateway/blackout protection features, switchboard upgrades, complex roof structures, or intricate building environments will now receive extended time allocations to ensure optimal long-term performance and compliance.

“Solar and battery technologies are becoming more advanced, and it’s essential that the supporting installation processes evolve with them,” said Derek McKercher, Director, McKercher Corporation. “These refined timeframes allow PSW Energy technicians to deliver consistent, high-quality outcomes without compromise—exactly what our customers expect from our brands.”

Aligned With ISO-Driven Quality Practices

The refinements also support McKercher Corporation’s broader commitment to ISO-aligned operational frameworks. By adjusting schedules to better match the technical nature of certain installations, PSW Energy continues to uphold rigorous documented procedures, continuous quality improvement practices, and the highest safety standards.

“These updates reinforce our dedication to delivering installations that meet every requirement of Australian Standards while supporting our ongoing pursuit of ISO-aligned excellence,” said Nicole Bilman, General Manager, PSW Energy. “It’s a proactive step, taken to ensure long-term reliability and safety for every customer.”

Customer Impact and Communication

Customers affected by the revised timeframes will be contacted directly with updated scheduling details. No action is required from customers unless notified. All other installations will proceed as initially planned.

The company emphasises that the refinements safeguard installation quality while ensuring that customer expectations remain clear and well-managed.
