You probably already know this. They list F1 and F2 together, It may have something to do with a leg imbalance.

F1 error AC Output Under Voltage

AC under-voltage shutdown at 210 V. The inverter has shut down to protect the loads.

Clear the fault and attempt restart. If problem persists, call customer service.

You might test it by dropping the AC loads and see if it still faults.
