PEA Addresses Sigenergy Inverter Safety Concerns in Thailand

The Provincial Electricity Authority (PEA) of Thailand has issued a statement regarding the safety of Sigenergy brand inverters, specifically the SigenStor EC 10.0 SP model, following concerns raised by a voluntary recall of similar products in Australia. On November 4, 2026, the PEA held an urgent meeting with representatives from Sigenergy Technology to investigate potential risks to local users. According to the manufacturer, the recall in Australia was limited to the 'SigenStor EC 10.0 SP AU' model. The technical issue was identified as improper installation, where bare wires were inserted directly into the quick-connect AC plug, violating the manufacturer's guidelines. This practice caused excessive heat, leading to automatic system shutdowns. The manufacturer has since updated the connector design to a safer OT terminal standard to resolve the issue. The PEA confirmed that they are reviewing the registration data for products currently in use within Thailand to ensure compliance with safety standards. For residents and business owners using these systems, it is recommended to verify the installation method used by their technicians and consult with authorized service providers to confirm if their specific hardware requires an upgrade to the new terminal design. Further updates regarding the status of these units in the Thai market are expected as the PEA continues its assessment.
