Your time is precious. Therefore, why waste it scouring the internet and sifting through product manuals? You are experiencing lost energy from the sun (potentially) and need a solution to your Goodwe error codes in a quick, simple and digestible manner.
Goodwe has a knack for making solar inverter technology beautifully simple, right down to their list of error codes which fall under two main categories. Your Goodwe error codes will be either a Goodwe classified System fault or Inverter failure.
Find your Goodwe error codes with ease:
1. Record the number displayed on the inverter.
2. Skip to your Goodwe error code using one of the buttons in the menu below.
Example: if you are aware that the fault you are experiencing is a system fault or an inverter failure, tap your preference in the menu. If not, explore the two categories for your error code.

Inverters have come a long way regarding safety features and intelligence. Chances are, the Goodwe error codes you are experiencing are external factors influencing the inverter’s programmed operation, identifying your circumstance as a system fault.
Grid-tied inverters have evolved to become intuitive, managing the energy user’s needs while negotiating variable grid conditions in diverse global regions. Should an inverter experience abnormal circumstances beyond the programmed limit, it will protect itself and you from any potential critical harm and notify the operator with a code that references deeper insight. These are your Goodwe error codes and what to do if you get one.
Tap one of these below buttons to jump to your particular Goodwe error codes;
System fault
Description: Fac Failure. Grid frequency out of range.
What to do: The PV inverter will automatically restart within 5 minutes if the grid returns to normal. If the problem persists, contact your solar installer.
Description: Isolation Failure. Ground insulation impedance is too low.
What to do: Check the impedance between PV(+)&PV(-) and make sure the inverter is earthed. The impedance value must be greater than 200kOhms. If the problem still persists, contact your solar installer.
Description: Vac Failure. Grid voltage out of range.
What to do: The PV inverter will automatically restart within 5 minutes if the grid returns to normal. If the problem persists, contact your solar installer.
Description: Ground Failure. High ground leakage current.
What to do: If the problem persists, contact your solar installer.
Description: Utility Loss. Grid disconnection/fault.
What to do: Check grid usability. If the problem persists, contact your solar installer.
Inverter failure
Description: SPI Failure. Internal communication failure.
What to do: 1. Turn off DC switch of the inverter. 2. Wait till inverter LCD unlighted. 3. Turn on DC switch and make sure it connected. 4. If the problem persists, contact your solar installer.
Description: EEEPROM R/W Failure. Memory chip failure.
What to do: 1. Turn off DC switch of the inverter. 2. Wait till inverter LCD unlighted. 3. Turn on DC switch and make sure it connected. 4. If the problem persists, contact your solar installer.
Description: Relay self-checking failure.
What to do: 1. Turn off DC switch of the inverter. 2. Wait till inverter LCD unlighted. 3. Turn on DC switch and make sure it connected. 4. If the problem persists, contact your solar installer.
Description: DC Injection High.
What to do: 1. Turn off DC switch of the inverter. 2. Wait till inverter LCD unlighted. 3. Turn on DC switch and make sure it connected. 4. If the problem persists, contact your solar installer.
Description: EFan Fault. External fan failure.
What to do: 1. Turn off DC switch of the inverter. 2. Wait till inverter LCD unlighted. 3. Turn on DC switch and make sure it connected. 4. If the problem persists, contact your solar installer.
Description: PV over-voltage.
What to do: If the problem persists, contact your solar installer.
Description: Over-temperature.
What to do: If the problem persists, contact your solar installer.
Description: IFan Fault. Internal fan failure.
What to do: 1. Turn off DC switch of the inverter. 2. Wait till inverter LCD unlighted. 3. Turn on DC switch and make sure it connected. 4. If the problem persists, contact your solar installer.
Description: DC Bus over-voltage.
What to do: 1. Turn off DC switch of the inverter. 2. Wait till inverter LCD unlighted. 3. Turn on DC switch and make sure it connected. 4. If the problem persists, contact your solar installer.
Description: Ref 1.5 Failure. 1.5V reference voltage failure.
What to do: If the problem persists, contact your solar installer.
Description: AC HCT Failure. Output current sensor failure.
What to do: If the problem persists, contact your solar installer.
Description: GFCI Failure. Detection circuit of ground leakage current failure.
What to do: If the problem persists, contact your solar installer.
Description: No display.
What to do: 1. Turn off DC switch, take off DC connector, check inverter module voltage. 2. Plug in DC connector, and turn on DC switch. 3. If voltage is lower than 250V, please check configuration of inverter module. 4. If the problem persists, contact your solar installer.
