Product Description:

This Off Grid Residential Solar Power Systems is mainly composed of a photovoltaic array composed of solar cells, a solar charge and discharge controller, a battery pack, an off-grid inverter, a DC load, and an AC load. The photovoltaic array converts solar energy into electric energy in the presence of light, supplies power to the load through the solar charge and discharge controller, and simultaneously charges the battery pack. When there is no sunlight , the battery pack supplies power to the DC load through the solar charge and discharge controller. At the same time, the AC power through the independent inverter to supply power to the AC load.


This Off Grid Residential Solar Power System is simple in structure, small in size, light in weight, easy to use and maintain. It is easy to install and transport, and has a short construction period. It has no radiation, no pollution, no noise, energy saving and environmental protection during use. Off Grid Residential Solar Power System is reliable and has a service life of at least 25 years, so it is very suitable to buy it. The off-grid residential solar power generation system has high photoelectric conversion efficiency and generates a large amount of power per unit area.
