What to do if Goodwe GW4200D-NS shows Relay-Check Failure?
If your Goodwe Inverter is experiencing an Inverter Failure due to Relay-Check Failure, follow these steps: 1. Turn off the DC switch of the inverter. 2. Wait until the LCD light turns off. 3. Turn on the DC switch, ensuring it is properly connected. If the problem persists, contact your local service office for further assistance.
What causes Over Temperature error on Goodwe Inverter 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 GW4200D-NS 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 GW4200D-NS 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 to do if my Goodwe GW4200D-NS Inverter 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.
Why is my Goodwe GW4200D-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 cool down my Goodwe GW4200D-NS if it shows 'Over Temperature'?
If your Goodwe inverter is showing an 'Over Temperature' warning, you can try the following: 1. Decrease the ambient temperature around the inverter. 2. Move the inverter to a cooler location.
What to do if my Goodwe GW4200D-NS Inverter has Vac Failure?
If your Goodwe Inverter shows a Vac Failure, it could be due to several reasons: * The grid voltage might not be within the required specifications. * The neutral (N) wire and PE cable might not be properly connected. First, the PV Inverter will automatically restart within 5 minutes if the grid returns to normal. Ensure the grid voltage aligns with the specified requirements and that the neutral wire and PE cable are securely connected. If the issue persists, it may be necessary to seek assistance from a local service office.
What to do if my Goodwe GW4200D-NS Inverter displays 'Utility Loss'?
If your Goodwe inverter indicates a 'Utility Loss', please check the following: 1. Ensure the inverter is properly connected to the power grid. 2. Verify that the power grid is connected to the cable. 3. Confirm the availability of the power grid.
What to do if my Goodwe GW4200D-NS Inverter shows 'Isolation Failure'?
If your Goodwe inverter displays an 'Isolation Failure', follow these steps: 1. Check the impedance between the ground and PV (+) & PV (-). The impedance value must be greater than 100kΩ. Ensure the inverter is properly grounded. 2. If the problem persists, contact your local service office for assistance. Additionally, the inverter has a built-in buzzer that will sound continuously for 1 minute upon failure. If the fault isn't resolved, the buzzer will sound every 30 minutes. You can also add the inverter to a monitoring platform and set up alarm reminders to receive email notifications about alarm information.
