PEA Clarifies Sigenergy Inverter Recall Concerns in Thailand
The Provincial Electricity Authority (PEA) has clarified safety concerns around Sigenergy inverters after a voluntary recall in Australia. The issue involved improper installation of SigenStor EC 10.0 SP AU units, not a product defect, and the manufacturer has since upgraded connectors. PEA confirmed 32 units with the original connector type are installed in its service areas, with no issues reported, and will conduct joint safety inspections with Sigenergy.
After social media reports about Sigenergy inverter recalls in Australia raised concerns about the SigenStor EC 10.0 SP model registered with the Provincial Electricity Authority (PEA), PEA promptly invited Sigenergy Technology Co., Ltd. representatives for urgent talks on November 4, 2026. The discussions revealed the Australian issue affects the SigenStor EC 10.0 SP AU model, caused by installers inserting bare wires directly into quick-connect AC plugs against manufacturer guidelines, leading to overheating and shutdowns. The manufacturer initiated a voluntary recall in Australia and has since replaced connectors with safer OT terminals.
PEA registration data shows the SigenStor EC 10.0 SP model was registered on May 8, 2025, using the original connector type. Sigenergy reports 48 units with the old connector were sold in Thailand, 32 within PEA service areas, with no operational issues reported domestically so far.
PEA and Sigenergy will jointly monitor, inspect, and test the 32 installed units in PEA areas to ensure safety. Users or installers finding equipment with the original quick-connect AC plugs should contact PEA's Equipment Quality Research and Control Division at 02-590-5578 or 02-590-5572, or email Sigenergy at [email protected]. Sigenergy confirms all current models sold in Thailand already feature the upgraded OT terminals. PEA will continue working to ensure product quality and safety while transparently sharing accurate information with the public.
