GoodWe SPI failure: Internal communication fault
GoodWe SPI failure usually indicates an internal communication problem within the inverter. Depending on the model, this may appear as an inverter failure, system fault, or control board issue.
Possible causes include failure to read the master or slave chips on the control board or other internal communication errors. This can affect inverter operation and prevent normal energy conversion or monitoring functions.
