from solar and battery. If solar priority, output source turn to utility side in case solar panel without energy or
battery voltage down to pre-alarm level. If sbu priority, output source turn to utility side in case of battery
voltage down to pre setting 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.
