What does Growatt Error 200 mean?
Short answer
Error 200 is an arc-fault (AFCI) trip: the inverter has detected an electric arc in the solar wiring. Growatt says it then shuts down permanently. The red light stays on and the buzzer sounds. Leave it off and call a PV installer to inspect the DC connections before any restart. Error 425 means the AFCI self-test failed.
