What to do if my Goodwe Inverter shows 'PV Over Voltage'?
If your Goodwe Inverter displays a 'PV Over Voltage' error, follow these steps: First, turn off the DC switch, then disconnect both the AC and DC connectors. Check the PV string voltage to see if it exceeds the input voltage specified for your inverter. If it does, reconfigure the PV panel string. If the problem persists, contact your local service office for assistance.
What to do if my Goodwe GW8500-MS Inverter shows 'Utility Loss'?
If your Goodwe Inverter shows a 'Utility Loss' message, take these steps: Begin by turning off the DC switch and disconnecting both the AC and DC connectors. Measure the voltage between the live line and neutral wire in the connector to ensure it meets grid-connected specifications. If it does not conform, check the distribution switch and grid for normal operation. If the voltage is within specification, reconnect the AC and DC connectors. Should the issue persist, contact your local service office.
What to do if my Goodwe GW8500-MS displays 'Isolation Failure'?
If your Goodwe Inverter is showing an 'Isolation Failure', here’s what to do: First, turn off the DC switch, then disconnect both the DC and AC connectors. Check the impedance between PV (+) & PV (-) to earth. If the impedance is less than 100K Ohms, inspect the insulation of the PV string wiring to the earth. If the impedance is greater than 100K Ohms, contact your local service office. Also, disconnect the AC connector and measure the impedance between the neutral wire and PE line; if it is greater than 10K Ohms, check the AC wiring.
What should I do if my Goodwe Inverter shows 'Ground I Failure'?
If your Goodwe Inverter is displaying a 'Ground I Failure', follow these steps: First, turn off the DC switch, then disconnect both the DC connector and AC connector. Check the insulation of the PV string wiring to the earth. Restart the DC switch. If the problem continues, please contact your local service office.
What should I do if my Goodwe GW8500-MS shows 'Vac Failure'?
If your Goodwe Inverter is displaying a 'Vac Failure', follow these steps: First, turn off the DC switch, then disconnect the AC connector and DC connector. Measure the voltage between the live line and neutral wire in the connector, and check if it conforms to the grid-connected specification of the inverter. If it does not, check the grid wiring. If it conforms to the specification, reconnect the AC connector and restart the DC switch to allow the inverter to connect to the grid automatically. If the problem persists, contact your local service office.
What to do if Goodwe GW8500-MS has no display?
If your Goodwe Inverter has no display, follow these steps: Turn off the DC switch and disconnect the DC connector, then measure the voltage of the PV array. Plug in the DC connector and turn on the DC switch. If the PV array voltage is lower than 150V, check the configuration of the invert module. If the voltage is higher than 150V and the issue remains, please contact your local office.
How to resolve 'Over Temperature' error on Goodwe Inverter?
To resolve an 'Over Temperature' error on your Goodwe Inverter: 1. Turn off the DC switch, then disconnect the AC and DC connectors. 2. Reduce the ambient temperature around the inverter. 3. Move the inverter to a cooler location. If the problem continues, contact your local service office for further assistance.
