What to do if my Goodwe NS Inverter displays a Fac Failure?
If your Goodwe Inverter displays a 'Fac Failure', the grid may not be connected. Check the grid connection cables and verify the grid's availability.
Why is my Goodwe NS displaying a Vac Failure?
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 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 should I do if my Goodwe Inverter shows Ground I Failure?
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?
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.
What to do if my Goodwe Inverter indicates a Utility Loss?
If your Goodwe Inverter shows a 'Utility Loss', first, make sure that the inverter is connected to the grid. Then, check the cable connection to the power grid and confirm the power grid's availability.
What to do if my Goodwe NS displays a Ground I Failure?
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 to do if my Goodwe NS Inverter displays a Vac Failure?
If your Goodwe Inverter shows a 'Vac Failure', the inverter will automatically restart within 5 minutes if the grid returns to normal. Ensure the grid voltage meets the required specifications and that the neutral (N) and PE wires are securely connected. If problems continue, contact your local service office.
How to address Low Generation issues with my Goodwe NS Inverter?
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?
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.
