If the alarm occurs occasionally, the possible cause is that
the electric grid is abnormal occasionally. SOFAR inverter
automatically returns to normal operating status when the
electric grid’s back to normal.
If the alarm occurs frequently, check whether the grid
voltage/frequency is within the acceptable range. If no,
contact SOFAR technical support. If yes, check the AC
circuit breaker and AC wiring of the SOFAR inverter.
