pure sine wave inverter Features:

Sine wave output: Can offer sensibility load and other kind of loads, such as electric fan, refrigerator,air-condition, electromotor and computer and so on.

Mono-microcomputer controlls the solar inverters: It produces the wave shape and makes the frequency of the inverter stable including auto-controll voltage.

Low down the speed of open: When we used high power loads, the inverter can low down the speed of open in order to protect the electrical products on load and itself.

Overloading protection: When inverter is connected the excessive loads and the total power of loads exceeds its tolerance, the inverter will be sound and the red LED will get light .Then the inverter will stop working and turn into the self-protection state.

Short circuit protection: When the interior of the appliance starts short circuit, the inverter will stop output and lock up. Then the red LED will get light and the inverter will turn into the self-protection state.

Discharge protection: When the voltage of the battery is lower than21.5V, the inverter will be sound and the LED will get light. Then the inverter will be stop output and lock up with in 5 minutes
