Basic Information
Product Description

300w Solar Energy Systems Home 1000w Off Grid

frequency inverter

Application scenario:small households, especially in remote rural areas, highland, hilltops, islands, pastoral areas, 

border guard posts, etc. , away from the power grid or power grid underdeveloped areas of the military and civilian electricity.

Ancillary equipment:solar panel, Solar Controller, storage battery, off-grid inverter, solar bracket,led lighting / Wire, etc

off grid inverter

Self-generating self-use power supply, without the need to be integrated into the power grid, to effectively

 solve the basic life-use electricity of the military and the civilian in the power-free areas;

Household-type off-grid power generation system can also be used as emergency power generation equipment

in power-unstable areas and enhance the safety of power consumption.

solar power inverter

frequency inverter

Can start without battery, wide range of input voltage(165-275VAC), accurate output and full automatic voltage stabilization.

Perfect protection. Protect against anti-charge at night, battery over charger/over discharge, output short-circuit, against overload, 

against over-voltage, over-current protection ,etc.

off grid inverter

1. Living house and home building

2. Office building, factory and warehouse

3. Home lighting: rural area, islands where lack of electricity, backup power

4. Power station, field operation and some huge engineer construction.
