What is a photovoltaic off-grid power generation system?

The photovoltaic off-grid power generation system is generally composed of a photovoltaic array composed of solar cell components, a solar controller, an inverter, a battery bank, and a load. The photovoltaic array converts solar energy into electric energy under the condition of light, and supplies power to the load through the solar controller, inverter (or inverter integrated machine), and charges the battery pack at the same time; when there is no light, the battery passes the inverter The device supplies power to the AC load.

The photovoltaic off-grid power generation system operates independently without relying on the power grid. It is widely used in remote mountainous areas, non-electric areas, islands, communication base stations and street lamps. The use of solar power generation solves the problem of residents in areas without electricity, lack of electricity and unstable electricity, schools Or the domestic and working electricity needs of small factories, photovoltaic power generation can partially or completely replace the power generation function of diesel generators with the advantages of economy, cleanliness, environmental protection, and no noise.
