cluster does not exceed the specified limit.
4) Confirm that the corresponding AC box circuit breaker
is in a state of disconnection.
3. When connecting the input cable, ensure that the positive
and negative poles of the input cable correspond to the
positive and negative poles of the PV terminals of the series
inverter.
