Process Of System Turning Off - Pylontech PowerCube-H1-V2 Operation Manual

3.8. Process of System Turning Off

When failure or before maintenance service, must turn the battery system off:
（1）Soft-off the PCS through PCS's control panel.
（2）Turn off the switch between PCS and battery strings (PowerCube-H1/H2-V2), or turn off the
power switch of PCS, to make sure no current transmission through BESS and PCS.
（3）Turn off the "Power Switch" of all the BMS.
（4）Turn off the "Power Switch" of the MBMS. If the battery system configures only single control
module and battery modules without MBMS, then ignore this operation step.
（5）Turn off the UPS if configured.
The UPS can turn on if have equipment must keep running. Otherwise suggest turn off the UPS to save
power.
Caution: Before change the battery module for service, must charge/discharge the replaced
battery to same voltage as the other modules in the system. Otherwise system needs long
time to do the balance for such replacement module.
Warning: Do not turn off the "Power Switch" during normal running condition. Otherwise it
will cause this battery string current surge by another battery strings. If turned off the "Power
Switch" in normal running condition, it must first turn off the PCS.
