4.1.1 Single String System Power On

Warning: Double check all the power cables and communication cables. Make sure the
voltage of the inverter/PCS matches the voltage of the battery system. Check to make
sure all the power switches are OFF.
System Power On Procedure:
1. Check the grounding is connected.
2. Check all the cables are connected correctly.
3. If necessary, turn on the switch for battery on the inverter or the switch between inverter
and battery system. If possible, turn on AC or PV power source to wake up the inverter.
4. Open the protection cover of Power Switch on the control module (BMS). And turn on
Power Switch.
5. Press Start Button for at least 5 seconds or until buzzer rings. Battery takes 10-30s for self-
checking.
If the inverter is powered by AC or PV source, most types inverters can set up communication
with BMS automatically, in this case, the BMS will close relay and system is ready for work.
If after 30sec self-checking the LED becomes as follows, this means the inverter needs to be
powered on by the battery energy:
Status:
In this case, press the Start Button for at least 10 secs, till the Status LED lighting Blue and fast
flashing. Then the battery will perform black start to support the inverter. After the inverter is
started and communication is set, the BMS is ready for work.
If the battery has been configured to a different communication protocol, please follow LED
Long Press 2 guidance in section 2.2.3.2. Make sure to select the correct protocol and restart
BMS to enable the communication with inverter.
Caution: If the breaker is tripped off due to over current or short circuit, be sure to wait
more than 30mins, then it can be turned on again; otherwise it may cause damage to
the breaker.
