Caution: The time interval between every time switch OFF/ON the “Power Switch” shall > 3
minutes .
Caution: When the breaker is tripped off because the system has over current or short circuit,
must after 30min to turn on it again, otherwise may cause the breaker damage.

Turn on the “Start Button”:
Press and hold the Start Button for more than 5 sets
until the buzzer rings, the LED indicator on front panel

System start process:
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. Normally the self-check will be finish within 30sec.
If long press the start button again within 30s during BMS self-check, the“STATUS” lamp will
flash red, it is to remind that the black start function is activated within 30s for 10min.
If MBMS is using internal power supply from BMS, please first use black start function to
provide power supply to MBMS, for further establish the external communication.
If there is no communication from upper equipment because of the communication is off,
the “STATUS” lamp will light red after 30sec. That doesn’t means 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 shows red from beginning, it means has failure in the battery string,
the Power Relays in BMS will switch ON, must debug at first.
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 fully
charge requesting during continuous operation as well, it will be handled automatically
by the communication between BESS and external device.
