What to do if my GE GEP12-L-10 shows Utility Loss?
- T
  Troy GomezAug 16, 2025
  If your GE Inverter indicates a Utility Loss, follow these steps: First, disconnect the DC switch and remove the AC connector. Then, measure the voltage between line and neutral in the connector to ensure it conforms to the inverter's grid-connected specification. If it doesn't, inspect the grid wiring and check if the distribution switch is connected and the grid is functioning correctly. If the voltage is correct, reconnect the AC and DC connectors. If the problem persists, further assistance is needed.

What should I do if my GE GEP12-L-10 Inverter displays 'PV Over Voltage'?
- B
  Brittany CarterAug 19, 2025
  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 GEP12-L-10 shows Vac Failure?
- A
  Amber RobinsonAug 22, 2025
  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?
- P
  Patrick MartinAug 26, 2025
  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.

Why is my GE Inverter not displaying anything?
- H
  Heather CardenasAug 31, 2025
  If your GE Inverter's display is blank, follow these steps: First, disconnect the DC switch and remove the DC connector. Measure the voltage of the PV string. Next, plug in the DC connector and reconnect the DC switch. If the voltage is less than 70 V, check the PV string configuration. If the voltage is higher than 180V and there's still no display, further assistance is needed.

  If your GE Inverter indicates a utility loss, take the following steps: 1. Disconnect the DC switch and take off the AC connector. Then, measure the voltage between line and neutral in the connector to ensure it conforms to the grid-connected specification of the inverter. 2. If it does not conform, check if the distribution switch is connected and the grid is normal. 3. If it does conform, reconnect the AC connector and DC connector.
