2.4.2 Working Modes
2.4.2.1 Normal Mode
In normal mode, the rectifier converts AC power into DC power. Then the inverter converts
DC power into AC output. At the same time, the rectifier charges batteries over a charger. The
two conversions ensure high-precision and high-quality output voltages, protecting loads from
interferences such as input harmonics, glitches, and voltage transients.
