What to do if my Goodwe Inverter displays GFCI Failure?
If your Goodwe inverter displays a 'GFCI Failure', which indicates a current leakage test equipment failure, update the firmware to the latest version.
What causes Over Temperature error on Goodwe GW2500-NS and how to fix it?
The 'Over Temperature' error on your Goodwe Inverter indicates that the internal temperature is higher than normal. Try to decrease the ambient temperature or move the inverter to a cooler location.
Why does my Goodwe GW2500-NS Inverter show Utility Loss?
A 'Utility Loss' message on your Goodwe Inverter indicates a disconnection from the power grid. Check if the power grid is connected to the cable and verify the availability of the power grid.
What to do if my Goodwe GW2500-NS Inverter displays PV Over Voltage?
If your Goodwe Inverter is showing a 'PV Over Voltage' error, check if the PV open circuit voltage is higher than or too close to the maximum input voltage.
What does Isolation Failure mean on my Goodwe GW2500-NS Inverter and how can I resolve it?
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.
What does Fac Failure mean on Goodwe Inverter and how can I fix it?
A 'Fac Failure' on your Goodwe inverter means that the grid frequency is out of the acceptable range. To troubleshoot: * Ensure the AC switch is in the ‘ON’ position to confirm the inverter is connected to the grid. * Verify that the safety country setting in the inverter is correct. Change it if necessary. * Check the ‘Fac’ value displayed on the screen. If it's outside the regulation limits, widen the frequency range using the ‘Calibrate Tool’.
Why is my Goodwe Inverter showing a Blank Screen?
If your Goodwe Inverter screen is blank when the DC is on, try these steps: * Measure the DC voltage to ensure it's higher than the start-up voltage. * Check if the PV string poles are reversed. * Inspect the DC and AC connectors for any damage. * Disconnect both AC and DC power from the inverter, wait 15 minutes, and then reconnect.
How to fix Relay Check Failure on a Goodwe Inverter?
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.
What does ISO Failure mean on my Goodwe GW2500-NS and how to fix it?
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 GW2500-NS shows Utility Loss?
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.
