inverters connected in parallel.
Regarding cable size of AC input and output, please also follow the same principle.
CAUTION!! Please install a breaker at the battery side. This will ensure the inverter can
be securely disconnected during maintenance and fully protected from overcurrent of
battery.
Recommended breaker specification of battery for each inverter:
Model
One unit*
LV 6KW
200A/60VDC
*If you want to use only one breaker at the battery side for the whole system, the rating
of the breaker should be X times current of one unit. “X” indicates the number of
inverters connected in parallel.
