7. OPERATION MODES OF THE SOLAR INVERTER
7.1 Solar Inverter System Block Diagram
7.2 Normal Operation
There are two main loops when AC utility is normal: the AC loop and the
battery charging loop. The AC output power comes from AC utility input and
passes through static switch to support power to load. The battery charging
voltage comes from AC utility input and converted by AC/DC charger to
support battery-charging power.
