goes up to 50Amp if solar panel with enough energy. Charger source will be turned to utility side in case solar
panel without enough energy.
7) When utility and solar are presented, battery charged from both solar and utility, I

+I
UC
, load powered
from solar and battery. Output source will be turned to utility side in case battery voltage down to pre-alarm
level.
Ex. 3KVA Model, AC Load = 2000W
i.e. I
LOAD
≈ 8.7Amp and I
DISC
≈ 92Amp
Max. I
CHG
= 50Amp, it means battery always stay in discharge situation since the required power of AC load is
larger than charging. Once battery down to pre-alarm level, AC load will be powered from utility then I
DISC
become zero.
