GoodWe error 26: Battery licence fault
GoodWe inverter alarm 26 usually means there is an issue with the battery activation or licence code.
This may occur if the battery was not properly activated, the code is incorrect, or there is a mismatch between the inverter and battery settings.
Contact e-Solar for battery verification and licence support

Contact e-Solar and let us know:

- When the code appears
