Sigenergy SigenStor AC Plug Recall for Burn Risk
Summary
Sigenergy has initiated a modification programme for its SigenStor Energy Controllers with quick connect AC plugs following identification of a burn risk. The affected products are 8.0kW, 10.0kW and 12.0kW connectors for single phase supply (PNs 1104002700, 1104002800, 1104002900) manufactured in China. The hazard arises when the quick connect AC plug has been installed not in accordance with the manufacturer's instructions, potentially causing overheating. The manufacturer will warn customers and arrange on-site inspection and repair. Products installed and commissioned after February 2026 are unaffected.

What changed
OPSS published a product safety report on 23 April 2026 classifying the Sigenergy SigenStor Energy Controller quick connect AC plug as presenting a low-level burn risk when installed incorrectly. The manufacturer has voluntarily initiated a modification programme rather than a full product recall, offering on-site inspection and repair to affected customers. The affected models cover three power ratings for single phase supply and can be identified by their part numbers.
Distributors and installers of Sigenergy SigenStor products should verify whether any 8.0kW, 10.0kW or 12.0kW units supplied for single phase installation carry the affected part numbers, and should alert end-user customers to the manufacturer's contact point for inspection requests. End-users who commissioned installations before February 2026 should contact sigenservice.uk@sigenergy.com if they have not already received notification.
