2. Normal Operation
There are two main loops when AC Utility normal the AC output loop and the
battery charging loop. The AC output gets power from AC utility input and
pass through AVR to support power to load. In the same time, the AC utility
input is converted by AC/DC CHA and support charging power to charge
batteries.
