GoodWe error 00: GFCI check timeout
GoodWe error 00 usually indicates that the GFCI (Ground Fault Circuit Interrupter) value exceeded acceptable limits during the self-check procedure. When this happens, the inverter may pause operation to ensure safe conditions for the system.
This is often a temporary or intermittent fault, but repeated occurrences may point to wiring issues, insulation problems, or a failing GFCI module. It does not always indicate an internal inverter failure, but safety protocols prevent normal operation until the condition is cleared.
Let e-Solar inspect the GFCI and inverter safety systems
If the error occurs once and clears by itself, your inverter may have simply reacted to a temporary spike in the GFCI measurement. The system usually resumes normal operation once the fault resolves.
If GoodWe error 00 keeps returning, contact e-Solar. Our Perth-based solar technicians can inspect the inverter, test the GFCI circuit, and verify whether the issue is linked to wiring, insulation, or the internal safety system.
Contact e-Solar and let us know:
- The exact error code on the screen or app
- When the code appears
- Whether your solar production has dropped
- Your inverter model, if you know it
Do not attempt to open the inverter or test high-voltage DC wiring yourself. If the issue persists, a qualified technician may need to safely measure GFCI values and verify inverter safety systems.
