System Power Off - Pylontech Force-H3 Operation Manual

4.2 System Power Off

Danger: When any failure occurs or there is a need for service, the battery storage system
must be powered off at first.
System Power Off Procedure:
1. Turn off inverter or power supply on DC side.
2. Turn off the switch between PCS and battery system.
3. Turn off the "Power Switch" of the all BMSs.
Caution: Before replace the battery module for service, make sure to charge/discharge
the existing battery module voltage similar to the replaced one. Otherwise the system
needs long time to do balance for this replaced battery module.
Caution: When restart is required for any troubleshooting steps, make sure to restart the
entire system (every BMS within the system). Please do not only restart partially of the
BMS within the system, which will further lead to error.
