How to resolve a Screen Fault on my Goodwe NS Inverter?
If you're experiencing a screen fault on your Goodwe Inverter (missing information, a messy display, no backlight, or the backlight is always on), remove the cover and reconnect the ribbon cable between the screen and the PCB.
What to do if my Goodwe Inverter displays PV Over Voltage Failure?
If your Goodwe Inverter shows a 'PV Over Voltage Failure', it indicates that the DC input voltage is too high. Here’s how to address it: * Check the number of panels in each string and measure the Voc (open-circuit voltage) of the panel. If the values exceed the limit, adjust the PV string connections. * If the PV string configuration is correct, check the ‘Vpv’ value displayed on the inverter screen. If the displayed value doesn't match your measurement, contact GoodWe local service center.
What to do if my Goodwe 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.
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’.
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.
Why is my Goodwe NS 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.
What causes Over Temperature Failure in Goodwe Inverter and how to resolve it?
If your Goodwe Inverter is showing an Over Temperature Failure, it means the inverter is getting too hot. Here's what you can do: * Ensure the inverter is installed according to the user manual's guidelines for positioning and ventilation. * Try to lower the ambient temperature around the inverter. Shut it down for 15 minutes, then restart it. If the fault persists, contact a GoodWe service center.
What to do if my Goodwe Inverter has WiFi Monitoring Failure?
If you're experiencing WiFi Monitoring Failure with your Goodwe Inverter, consider these steps: * First, confirm that your inverter is indeed a WiFi-enabled model. * Check the 'Power' light on the inverter. If it's solid, try modifying the communication mode. * Try reloading the WiFi module to see if the Solar-WiFi connection stabilizes. * Remove the inverter cover and reconnect the ribbon cable of the WiFi module.
Why is my Goodwe NS stuck in 'Waiting' mode?
If your Goodwe Inverter remains in 'Waiting' mode, here are a couple of things to check: * When using the inverter for the first time, ensure the DC switch is on while keeping the AC switch off. Otherwise, the inverter will remain in 'Waiting' mode. * Measure the DC voltage of the inverter to ensure it exceeds the start-up voltage requirement.
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.
