1. Low frequency durable transformer
2. auto switch to mains when mains recover
3. automatic charge when mains available

Inverter with charger (UPS function), applicable to home use; grid AC power is in priority for loads: When grid is power off, the inverter convert battery’s DC power to AC power and supply it to AC loads;When grid power recovers, the inverter automatically supply the AC power from the grid to the loads, at the same time charge the batteries.
