  If your SOLINTEG Inverter displays a Grid Voltage Fault, it means the inverter has detected that the grid voltage exceeds the safety limit. Here's what you can do: 1. Verify that the safety code is correct. 2. Ensure the AC cable wiring is properly connected. 3. If the voltage increase is due to high AC cable impedance, consider replacing it with a thicker cable. 4. With permission from the Electricity Authority, extend the voltage protection limit.
