Features:
1. Pure sine wave output, suitable for household appliances such as TV sets, refrigerators, induction cookers, fans, microwave ovens, air conditioners, etc.
2. Can withstand 3 times rated power start, high load capacity
3. Over 88% inverter efficiency, energy saving mode
4. Can be used with electricity, solar power, diesel generators mix
5. When the load is less than 50W, the machine will change to power saving mode
6. Automatic correction of power factor, more energy-efficient than ordinary charger
7. Input under/over voltage/short circuit/overload protection
8.LED display work and charge status
9. Remote control interface RJ11, RS232 (optional)
