I own an Anenji ANJ-SP-2200-12V inverter, which is currently not connected to any solar panels. It is, however, hooked up to a single LiFePO4 12V 150Ah battery and the utility grid. I'm encountering an issue where, every few seconds, the inverter detects voltage at the PV input and attempts to switch to PV. In second or so voltage disappears, causing the inverter to emit a loud beep and halt charging the battery from the utility grid. This cycle of detecting voltage and then losing it repeats continuously until the inverter is disconnected from power.
Upon measuring the voltage at the PV input, I confirmed it aligns with the inverter's readings, showing approximately 120V. I'm at a loss as to the source of this voltage and how to resolve the issue. Could this problem stem from incorrect installation, or is it indicative of a defect in the inverter itself?
