What to do if my Goodwe GW3000-NS displays PV Over Voltage Failure?
- R
  Randall SanchezSep 6, 2025
  If your Goodwe Inverter shows a 'PV Over Voltage Failure', it indicates that the DC input voltage is too high. Here’s how to address it: * Check the number of panels in each string and measure the Voc (open-circuit voltage) of the panel. If the values exceed the limit, adjust the PV string connections. * If the PV string configuration is correct, check the ‘Vpv’ value displayed on the inverter screen. If the displayed value doesn't match your measurement, contact GoodWe local service center.

Why is my Goodwe GW3000-NS Inverter displaying a Vac Failure?
- C
  Craig BarnesAug 25, 2025
  A 'Vac Failure' on your Goodwe inverter indicates that the grid voltage is out of the acceptable range. To resolve this: 1. Measure the voltage when the inverter displays ‘Vac Failure’. If it's outside the regulated limits, contact your electricity company. 2. Measure the voltage between N and PE on the inner AC side of the inverter; it should be less than 1V. If it's higher, check the AC wiring. 3. Compare the ‘Vac’ value on the inverter screen with the voltage measured at the switchboard. If they don't match, contact a GoodWe service center.

What does ISO Failure mean on my Goodwe GW3000-NS Inverter and how to fix it?
- C
  craigramosAug 26, 2025
  An ISO Failure on your Goodwe inverter indicates that the ground insulation impedance is too low. Here’s how to address it: * If the fault occurs at dawn, dusk, or during rainy days, it might be a temporary issue and can be ignored. * Measure the impedance of PV+ and PV- to ground. The values should be higher than 2MΩ. If the impedance is too low, inspect the insulation or rewire the PV connection. * Measure the impedance of N to ground; it should be close to zero. If not, check the AC wiring. * Ensure that the inverter's firmware is up to date. If not, update it to the latest version.

What should I do if my Goodwe Inverter shows Ground I Failure?
- G
  gomezkeithAug 27, 2025
  If your Goodwe Inverter displays a 'Ground I Failure', it means the inverter has detected high current leakage. Here's how to troubleshoot: * Disconnect all PV strings from the inverter. Then, connect each string individually to identify the faulty string. Inspect the wiring of that string for any damage. * If the fault only appears during rainy or wet weather, you can disregard the fault, as it might be due to temporary moisture.

How to troubleshoot a Goodwe Inverter that is Reconnecting?
- S
  Sherri SmithAug 27, 2025
  If your Goodwe inverter is continuously reconnecting, consider the following checks: * If this happens at dawn or dusk, it may be normal and can be ignored. * Verify the AC wiring, ensuring the N and PE lines are correctly wired. * Confirm that the regulation settings are correct for your location. * Check if any other fault messages appear while the inverter is reconnecting. * Note the countdown time remaining during the reconnection process and provide this information to GoodWe local service center if needed.

Why is my Goodwe Inverter stuck in 'Waiting' mode?
- M
  Margaret KimAug 28, 2025
  If your Goodwe Inverter remains in 'Waiting' mode, here are a couple of things to check: * When using the inverter for the first time, ensure the DC switch is on while keeping the AC switch off. Otherwise, the inverter will remain in 'Waiting' mode. * Measure the DC voltage of the inverter to ensure it exceeds the start-up voltage requirement.

What to do if my Goodwe GW3000-NS Inverter shows a Utility Loss error?
- J
  Jeremy RandallSep 12, 2025
  If your Goodwe Inverter displays 'Utility Loss', it means there's an issue with the grid connection. First, disconnect the DC switch and AC connector. Then, measure the voltage between line and neutral to ensure it meets the inverter's grid-connected specifications. If the voltage is incorrect, check the distribution switch and grid for normal operation. If the voltage is correct, reconnect the AC and DC connectors. If the problem persists, further assistance is needed.

How to resolve a Screen Fault on my Goodwe GW3000-NS Inverter?
- D
  Dr. Juan Woods DVMSep 7, 2025
  If you're experiencing a screen fault on your Goodwe Inverter (missing information, a messy display, no backlight, or the backlight is always on), remove the cover and reconnect the ribbon cable between the screen and the PCB.

How to address Low Generation issues with my Goodwe Inverter?
- K
  kimberlywebbSep 5, 2025
  If you're experiencing low power generation (E-day) with your Goodwe Inverter: * If the E-day value on the inverter screen is very low, check that the time setting on the inverter is correct. * If the E-day value on the portal is very low, ensure that the time zone setting in the portal is correct.

How to fix Relay Check Failure on a Goodwe Inverter?
- A
  Albert YoungSep 2, 2025
  If your Goodwe inverter is showing a Relay Check Failure, which indicates an output relay fault, try this: Switch on both the AC and DC power to the inverter. Listen carefully during the inverter's startup check. If you don't hear a relay clicking sound, contact GoodWe local service center.
