1. Main Features:
1. Input & output is fully insolated to endure impact of sensitive appliances and protect the inverter from being easily damaged.
2. High Surge: High surge current capability starts difficult loads such as TVs, camps, motors and other inductive loads.
3. Soft start: Smooth start-up of the appliances.
4. Pure sine wave output waveform: Clean power for sensitive loads.
5. Low total harmonic distortion: Below 5%
6. Stable working performance: Even in the situation of under voltage or over voltage, the inverter could endure 10% voltage fluctuation until it shutdowns.
7. Cooling fan with internal temperature sensor will turn on automatically when the inverters becomes warm and turn off after the temperature dropped.
8. LED indicator on the front panel shows the working and error state.
9. Digital displays indicate battery voltage and inverter output voltage.

2. Protect functions:
1. Over load protection
2. Over current protection
3. Over voltage protection
