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 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 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.
What does ISO Failure mean on my Goodwe GW4200D-NS Inverter 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.
Why is my Goodwe GW4200D-NS Inverter 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.
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 fix a Relay-Check Failure on a Goodwe GW4200D-NS?
To address a Relay-Check Failure on your Goodwe Inverter: 1. Turn off the DC switch of the inverter. 2. Wait until the LCD light is off. 3. Turn on the DC switch and ensure it is connected.
What does Isolation Failure mean on my Goodwe 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 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.
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.
