System Turns Off - Pylontech PowerCube-M1 Operation Manual

must after 30min to turn on it again, otherwise may cause the breaker damage.
The battery string's system will check itself, if work normal the battery string system will go

to self-check mode.
If the BMS and all battery modules are working normally, every status LED will lighting
green, that's mean self-check are pass. Self-check will be finish within 5sec.
The BMS can't receive communication from upper equipment because the
communication is off, the "STATUS" lamp will light red after 30sec. That doesn't means
failure existing, it means this battery string is working normally.
Warning: If has failure during the self-check, must debug the failure then can start next step.
If the "STATUS" lamp shows red from beginning, it means has failure in the battery string,
the Power Relays in BMS will switch ON, must debug at first.
(4) Switch the MBMS on after all the BMS turn on successful:
And check MBMS is working. The "STATUS" lamp will light green.
The Power Relays in BMS will switch ON after 30 seconds, when the MBMS was turned ON.
The "STATUS" lamp of the BMS will light green;
When the voltage distance is smaller than the parameter, the battery string will do the
parallel operation.
When the MBMS was turned ON, the "STATUS" lamp of the BMS will light red, but it is
normal;
Note: If the MBMS can't build communication with other equipment, the system can't
work normally. External Power should communicate with battery system through LAN,
CAN or RS485. Otherwise maybe cause battery system work abnormal.
Caution: The whole Battery Energy Storage System (BESS) after installation or restart the system
when long time not in using should charge it to full at first.

3.6.5 System turns off

When failure or before service, must turn the battery system off:
(1) Turn off the switch between PCS and this battery string (PowerCube-M1), or turn off the power
switch of PCS, to make sure no current through this battery string.
(2) Turn off the "Power
Switch" of the BMS.
(3) Turn off the "Power Switch" of
the BMS.
