What does ISO Failure mean on my Goodwe GW2000-NS Inverter and how to fix it?
- M
  Michael ClarkeSep 1, 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 to do if my Goodwe GW2000-NS shows a Utility Loss error?
- K
  Kevin MatthewsSep 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.

  If your Goodwe Inverter indicates a Utility Loss, it means the inverter isn't detecting a grid connection. Here's what you should do: * Ensure the AC switch is in the ‘ON’ position. If it is, use a multimeter to check the voltage at the AC connector and the main switchboard wiring to confirm the grid is active. * Verify that the L, N, and PE wires are connected to the correct pins. Adjust the wiring if necessary. * Check the ‘Vac’ value displayed on the screen against the actual grid voltage. If the values are outside the regulation limits, contact your electricity company. * Turn off both the AC and DC power to the inverter, wait 5 minutes, and then measure the impedance between L & N to ground. If the values are less than 200KΩ, contact the GoodWe local service center.

What does Vac Fail mean on my Goodwe GW2000-NS Inverter and how can I fix it?
- M

  If your Goodwe Inverter displays a 'Vac Fail' error, it indicates a voltage issue. Disconnect the DC switch and AC connector. Measure the voltage between the line and neutral in the connector to ensure it matches the inverter's grid-connected specifications. If it doesn't, inspect the grid wiring. If it does, reconnect the AC connector and DC switch; the inverter should automatically reconnect to the grid. If the problem persists, further assistance is needed.

How to fix an Over Temperature error on a Goodwe Inverter?
- R
  Richard GordonSep 13, 2025
  If your Goodwe Inverter is showing an 'Over Temperature' error, it could be due to the installation environment. Ensure the inverter's placement follows the specified guidelines. Try to reduce the ambient temperature around the unit. Consider moving the inverter to a more ventilated area or changing its installation position. If the issue continues, further assistance is needed.

What to do if my Goodwe GW2000-NS Inverter displays a Ground I Failure?
- S
  simpsonnicholasSep 18, 2025
  If your Goodwe Inverter shows a 'Ground I Failure', it means the ground current is too high. Try these steps: 1. Disconnect the inputs from the PV generator. 2. Check the AC system. 3. After clearing the problem, reconnect the PV panel and monitor the Inverter status. If the issue persists, contact your local service office.

What does Isolation Failure mean on my Goodwe GW2000-NS and how can I resolve it?
- P
  pellisAug 27, 2025
  An 'Isolation Failure' on your Goodwe Inverter suggests a problem with the impedance between the ground and PV (+) & PV (-). Check the impedance; the value must be greater than 100kΩ. Also, ensure the inverter is properly grounded.
