Battery Inverter Solar System 12v 40ah Battery

Home solar system provides universal DC-USB output port and DC output to be widely applied to small solar 

power generation occasions families, schools, street monitoring, forest monitoring, industrial and mining enterprises, 

frontier defense sea islands, pasturing areas.

Perfect protection: low voltage protection, over voltage protection, overheat protection, short-circuit protection, 

overloads protection; alarm alert.

Living house and home building, Office building, factory and warehouse, home lighting: rural area, islands

 where lack of electricity, backup power, power station, field operation and some huge engineer construction.
