How does low frequency inverter charger work?



1. Home backup system:

When AC grid power is available, inverter charges battery, at the same time, AC grid power bypass through inverter to household appliances, such as refrigerator, TV. When AC grid power is off, it will automatic transfer switch to battery power and convert DC to AC power.

2. Wind or Solar Power system:

Convert DC to AC power. When battery power is lacking, it will automatic transfer to grid power for powering continuously.
