If the ICC cabinet software needs to be upgraded during the initial site setup, use either of the following
power supply modes to perform the upgrade:
 Switch off the battery circuit breaker QF1 in the lithium battery cabinet. Perform the upgrade when
PV power is supplied to each power module in the ICC cabinet.
 Turn off the solar input switches of all power modules in the ICC cabinet. Perform the upgrade when
the ICC cabinet is powered by the lithium battery cabinet.
You can perform PV power-on commissioning only when the sunlight is normal.
Check that the PV input voltage is between 200 V DC to 980 V DC.
If the power indicator (green) on the front panel of the HSU is on, the cables are connected correctly. If
the indicator (green) is off, the positive and negative power cables may be reversely connected and need
to be corrected.
