Sigenergy Technology Co., Ltd. has issued a voluntary recall of certain single-phase Energy Controllers (8 kW, 10 kW, 12 kW) and SigenStor EC inverters that were sold throughout Australia. This decision follows the product change notice issued in October 2025 and demonstrates Sigenergy’s commitment to working with the ACCC, Clean Energy Council, and Clean Energy Regulator to ensure the highest standards of safety and performance.
What's Happening
Sigenergy has identified that some AC plugs on earlier single-phase inverter models may be susceptible to damage if installation procedures were not followed precisely.
Although the products themselves meet all design and safety standards, improper cable termination during installation can cause overheating at the AC connection under high load.
To address this, Sigenergy has:
- Introduced a new, ferrule-free AC plug design,
- Issued a firmware update adding real-time monitoring and automatic power adjustment under sustained load, and
- Launched a nationwide replacement program for all affected units.
Are My Products Affected?
Models included in this voluntary recall:
- SigenStor EC 8.0 SP / 10.0 SP / 12.0 SP
- Sigen Hybrid 8.0 SP / 10.0 SP / 12.0 SP
No three-phase models are affected.
Units with the green-dot label on packaging already feature the updated AC plug and are not subject to recall.
What Customers Should Do?
- Sigenergy system owners can continue using their Sigenergy system safely.
- No action is required immediately — Sigenergy or your installer will contact you to arrange a free replacement.
- Replacements include a 2-year warranty extension for added peace of mind.
If you’ve already received a firmware update notification, your system is operating under enhanced safety parameters until your replacement is scheduled.
For InstallerS
- Do not install or recommission any affected single-phase units.
- Register replacements through Sigenergy’s national service portal.
- A $500 service subsidy applies to approved replacements.
Ongoing Commitment
McKercher Corporation subsidiaries and Sigenergy are working closely with Australian regulators to ensure all affected units are replaced promptly and transparently. The voluntary Sigenergy recall underscores our shared commitment to safety, quality, and customer trust.
