Off Grid Residential Solar Power Systems

Solar system is the solution to solve customer's power problem by using sun power. According to different installed information and different power using, every system is different after design-off grid solar system ,on grid solar system ,hybrid solar system.

Product Details

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.


  1. Off Grid Residential Solar Power Systems has simple structure, small volume and light weight, easy to use and maintain

  2. Easy to install and transport, short construction period.

  3. No radiation, no pollution, no noise, energy saving and environmental protection.

  4. Reliable quality, long service life at least for 25 years.

  5. Off Grid Residential Solar Power Systems has high photoelectric conversion efficiency, and large power generation per unit area.
