Disconnect the AC output switch and DC input switch, then connect them 5 minutes later.
What to do if GE GEP Inverter shows Relay Check abnormal?
Disconnect the AC output switch and DC input switch, then connect them 5 minutes later.
What should I do if my GE Inverter displays 'PV Over Voltage'?
If your GE Inverter displays a 'PV Over Voltage' error, take these steps: First, disconnect the DC switch and remove the DC connector. Check the PV string voltage to ensure it does not exceed the input voltage specified for your inverter. If it does, reconfigure the PV panel string. If the problem continues, further assistance is required.
What to do if my GE GEP shows Vac Failure?
If your GE Inverter is showing a Vac Failure, follow these steps: First, disconnect the DC switch and remove the AC connector. Then, measure the voltage between the line and neutral in the connector to ensure it conforms to the inverter's grid-connected specification. If it does not, check the grid wiring. If it does, connect the AC connector and reconnect the DC switch, allowing the inverter to connect automatically. If the problem continues, further assistance is needed.
How to fix Isolation Failure on a GE Inverter?
To address an Isolation Failure on your GE Inverter, follow these steps: First, disconnect the DC switch and remove the DC connector. Check the impedance between PV (+) & PV (-) to earth. If the impedance is less than 100 kΩ, inspect the insulation of the PV string wiring to the earth. If the impedance is larger than 100 kΩ, further assistance is needed. Remove the AC connector and measure the impedance between neutral and PE. If it is larger than 10 kΩ, inspect the AC wiring.
What causes Internal Fan abnormal error on my GE GEP?
The fan power supply is abnormal. Disconnect the AC output switch and DC input switch, then connect them 5 minutes later.
What does PV Input Overvoltage mean on my GE Inverter?
The PV voltage is too high. Disconnect the AC output switch and DC input switch, then connect them 5 minutes later.
Why does my GE GEP show Grid Undervoltage?
If the issue happens occasionally, it could be due to a temporary problem with the utility grid. The inverter should automatically recover once it senses that the grid voltage is back within the normal range. If the grid voltage consistently falls below the permissible range, contact your local power company.
What causes Grid Overfrequency on a GE GEP Inverter?
This is due to a utility grid exception. If the problem occurs occasionally, the utility grid may be abnormal temporarily. The inverter will recover automatically after detecting that the utility grid is normal.
What to do if my GE GEP display is not working?
If your GE Inverter has no display, turn off the DC switch and take off the DC connector, then measure the voltage of the PV array. Plug in the DC connector and turn on the DC switch. If the PV array voltage is lower than 250V, check the configuration of the inverter module. If it is higher than 250V, contact a local service office.
What does 'Ground I Failure' mean on my GE GEP Inverter and how to fix it?
A 'Ground I Failure' on your GE Inverter indicates that the ground current is too high. To resolve this, take off the inputs from the PV generator and check the peripheral AC system. Once the problem is cleared, reconnect the PV panel and check the Inverter status. If the issue persists, contact a local service office.
