3.5.3 Switching on the System
Warning:
Double check all the power cables and communication cables. Make sure the voltage
of the inverter/PCS is same level with the battery system before connection. Check if all the power
switches are OFF.
Steps for switching system on
:
1)
Check if all cables are connected correctly. Check if the grounding is connected.
2)
If necessary, turn on the switch at the inverter`s battery side or between inverter and battery.
If possible, turn on AC or PV power source to wake up the inverter.
3)
Open the protection cover of the Power switch and turn on power switch.
4)
Press start button for at least 5 seconds or until the buzzer rings. The battery takes 10-30s for self-
checking.
If the inverter is turned on by AC or PV source, then most inverters can setup communication
with the BMS automatically. In this case, the BMS will close its relay and the system is ready for
work.
If the inverter needs battery power to turn on, then check the LED of the battery, it shall be:
Status: Orange, solid
SOC: blue, solid
In this case, press the Start button for at least 10s, till the Status lights blue and fast flashing, then
the battery will black start to support the inverter and after the inverter turned on and set up
communication, then BMS is ready for work.
Caution:
When the breaker is tripped off because of over current or short circuit, wait for 30min
to turn it on again, otherwise it may cause damage to the breaker.
