System Turns Off - Pylontech PowerCube-X1 Operation Manual

Warning: if the black-start function is used, the terminal of DC "+" and DC "-" will be electricity
dangerous with high DC voltage output.
(3) Switch the MBMS on after all the BMS turn on successful:
And check whether MBMS is working. The "STATUS" lamp will light green.
When the voltage difference between strings is smaller than the parameter, the battery
string will do the parallel operation. Then the power relays in BMS will switch ON after 30
seconds. The "STATUS" lamp of the BMS will light green;
When the voltage difference between strings is bigger than the parameter, the battery
string will NOT do the parallel operation, the "STATUS" lamp of the BMS will light red, but it
is normal; Such battery string will be paralleled in
during charging stage automatically.
Note: If there is no communication between
MBMS and upper controller, the system can't
work normally.
communicate with battery system through LAN,
CAN or RS485. Otherwise maybe cause battery system work abnormal.
Caution: During first time power on, the system will require to do fully charge progress for SOC
calibration purpose.
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.
There will be a regularly (3 month) fully charge requesting during continuous operation as well, it
will be handled automatically by the communication between BESS and external device.

3.6.5 System turns off

When failure or before service, must turn the battery storage system off:
(1) Soft-off the PCS through PCS's control panel.
(2) Turn off the switch between PCS and battery string (PowerCube-X1/X2), or turn off the power
switch of PCS, to make sure no current transmission through battery string and PCS.
(3) Turn off the "Power Switch" of the BMS.
(4) Turn off the "Power Switch" of the MBMS. If the ESS configures only single battery without MBMS,
then ignore this operation step.
