Why is my Goodwe MS Inverter showing a Ground I Failure?
A Ground I Failure on your Goodwe Inverter indicates that the ground current is too high. Unplug the inputs from the PV generator and check the peripheral AC system. After clearing the problem, reconnect the PV panel and check the Inverter status.
What should I do if my Goodwe MS Inverter displays a Fac Failure?
If your Goodwe Inverter displays a Fac Failure, it means that the grid is not connected. Check the grid connection cables and ensure the grid is available.
How to fix a Goodwe MS Wi-Fi module that fails to connect to the network?
If the Wi-Fi module fails to connect to the network after entering the correct router hotspot and password, the password might contain unsupported special characters. Change the password to include only Arabic numerals or uppercase/lowercase letters.
Why does my Goodwe Inverter show an Isolation Failure?
An Isolation Failure on your Goodwe Inverter suggests an insulation problem. Here's how to troubleshoot: 1. Disconnect the DC switch and remove the DC connector. Check the impedance between PV (+) & PV(-) to earth. 2. If the impedance is less than 100 kΩ, inspect the insulation of the PV string wiring to earth. 3. Take off AC connector, measure the impedance between neutral.
What causes a Utility Loss error on a Goodwe MS Inverter?
A Utility Loss error on your Goodwe Inverter means it is not connected to the grid. Check if the power grid cable is connected and verify the availability of the power grid.
What to do if my Goodwe MS Inverter shows a Vac Failure?
If your Goodwe Inverter displays a Vac Failure, it indicates a grid voltage issue. First, the inverter will automatically restart within 5 minutes if the grid returns to normal. Ensure the grid voltage conforms to the specified requirements and that the neutral (N) and PE wires are securely connected.
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.
What to do if Goodwe Inverter 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.
What should I do if my Goodwe 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 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.
