6.
Connect the RS485 port of the master battery module to the battery communication interface
of the inverter, meanwhile, connect the bus bar of the battery cabinet and the battery
input of the inverter through the system breaker;
7.
Starting from the master, turn on all battery modules by pressing the reset button, close the
battery
breakers one by one, and observe whether the breakers can’t be closed and any
overcurrent occurs
during the process. If all works normally, go to the next step; if there’s
battery breaker can’t be closed or overcurrent occurs, please measure the battery voltage
separately to evaluate whether it’s caused by a large voltage difference.

Enabling system
After completing above all steps, turn on the system breaker between the battery cabinet and
the inverter,
run the inverter and open the setting menu, then select 'Lib’ in the battery type,
and press the battery on switch to measure the battery voltage , If normal output then turn on
the battery to access breaker. At the same time, check whether the communication is normal,
if all is ready then enable the system.

Working at High/Low temperature
Do not charge the battery when it is used below 0
℃
, while if you want to make it, you need to
add internal
heating device to heat the battery temperature to ≥0
℃
and then charge the
battery. The charge factor of batteries in high and low temperature environments should follow
