7.2 Power-On of Energy Storage Battery Module
After power-on check and confirmation, first turn on the switch of the energy storage battery module. If there are
multiple modules, please turn on the power switch one by one according to the address sequence.

8 System Maintenance
8.1 System Power-Off
● After the system is powered off, the case still has residual power and heat, which may cause
electric shocks or burns. Therefore, protective gloves should be worn before operating the energy
storage 5 minutes after the system is powered off. Maintenance operations on energy storage
should be performed only after ensuring that all indicator lights of the energy storage are off.
● When the energy storage system is running, the system cannot be powered off completely
when only turning off the switch of the power unit. At this time, no maintenance operation can
be performed on the energy storage. The switch of energy storage must be turned off before
Power-off operation steps of the system:
Step 1 Turn off the switch between the power unit and AC output.
Step 2 Turn off the switch between the power unit and AC input.
Step 3 Turn off the switch between the power unit and the PV string.
Step 4 Turn off the switch between the power unit and the energy storage battery unit.
