system will entering into self-check mode automatically.
If the BMS and all battery modules are working normally, every status LED will be lighting
green, that’s mean self-check are pass. Self-check will be finish within 10sec.
Black-start function:
If long press(>10sec) the start button 30s
AFTER
power on. The
“
STATUS” lamp will
becomes green if the black start function is enabled. If
“
STATUS” lamp remain red, the
black start function is failed to active, need long press start button again. System will
close relay and output for 10mins.
Warning:
if the black-start function is enabled, the terminal of D+ and D- will be
electricity dangerous with high DC voltage output.
Note:
If the BMS can’t receive communication from upper equipment because of the
communication is off, the “STATUS” lamp will light red after 30sec. That doesn’t mean
failure existed, it means this battery string is OK while the external communication is off.
Warning:
If has failure during the self-check, must debug the failure then can start next
step.
If the “STATUS” lamp on BMS/battery shows red from beginning, it means there has some
failure in the battery string, the Power Relays in BMS will open, must debug at first.
Note:
The LED lamp will be off in 20sec without any operation.

Switch the MBMS on after all the BMS turn on successful:
If MBMS is working normally, the “STATUS” lamp will light green. The “STATUS” lamp of the BMS will
light green; The Power Relays in BMS will activate after 30 seconds when the MBMS was turned
ON.
When the voltage difference between different strings is within the relevant range, these strings
will do the parallel operation (Power Relay Close). The strings exceed the voltage difference
range will be paralleled later.
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 Modbus.
Otherwise maybe cause battery system work abnormal.
