4Installing ESMs
1. Before installing batteries, carefully read the battery safety precautions.
2. Wear insulation gloves and use insulated tools during installation.
3. Place the batteries in a correct way to prevent vibrations and shocks.
1. Remove filler panels from the cabinet based on the actual number of ESMs.
2. To facilitate battery installation, install the auxiliary support on the cabinet first.
3. Install ESMs.
The address of the ESM above the BCU in the right cabinet must be always 1 (the first ESM
displayed on the SBCU), and the address of the ESM at the bottom layer in the left cabinet must
always be the last value (the last ESM displayed on the SBCU). If a cabinet is not fully configured,
the vacant slots are always on the top of the cabinet and covered by filler panels.
Place ESMs from bottom to top and from left to right. To prevent falling over due to overweight,
ensure that the cumulative height of ESMs in the right cabinet is one ESM greater than or
equal to the cumulative height of ESMs in the left cabinet.

Power-On Mode of the ICC Cabinet
7.2
Check that the PV input, battery, and AC input and output cables are correctly connected.
Turn the solar input switch in the ICC cabinet to ON.
Powering On the ICC Cabinet Using PV
•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.
Powering On the ICC Cabinet Using a Lithium Battery
•The battery supply is connected preferentially at night or when PV energy is insufficient.
•Required tools such as a multimeter and insulation gloves are available.
•The PV switch and AC output switch in the ICC cabinet are OFF.
•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.
7Power-on Commissioning
Preparing for Power-On
7.1
Turn on the battery breaker QF1 in the lithium battery cabinet.
Turn on the BCU power switch QS1 in the lithium battery cabinet.
(Optional) If there are multiple lithium battery cabinets, repeat the preceding steps.
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.
