Turn the AC output switch in the cabinet to OFF.
Turn the AC input switch in the cabinet to OFF.

Turn the AC input switch to ON.
Setting Parameters for the ICC Cabinet
7.3
Turn on the battery cold-start breaker QF2 in the lithium battery cabinet.
Hold down the battery startup button (BATT Start) for 5s
Check that the battery terminal voltage of the ICC cabinet is normal (should be the same as the
voltage of the lithium battery cabinet).
Powering On the ICC Cabinet Using a Backup DG
• When there is no PV input and the battery depth of discharge (DOD) reaches the specified
value, you need to start the backup DG to charge the batteries.
• When the power of the backup DG is less than the load power, power off the load.
• If the green power indicator on the front panel of the BPS is on, the BPS works normally. If
the red indicator is on, the DG input phase sequence may be reverse or the input voltage
frequency may exceed the limit. In this case, they need to be checked.
