Basic Information
Off-grid photovoltaic power generation system is also called an independent photovoltaic power generation system. It can operate independently without relying on the power grid, converting light energy into electrical energy, which can effectively solve problems caused by power shortages, power outages, etc.
Since the off-grid photovoltaic power generation system is not restricted by geography, it is widely used and can be installed and used wherever there is sunlight, achieving "where there is light, there is electricity." Off-grid photovoltaic power generation systems are very suitable for use in remote areas without power grids, and can also be used as emergency power generation equipment in areas with frequent power outages.
System composition
Off-grid photovoltaic systems generally consist of photovoltaic arrays composed of solar cell modules, solar charge and discharge controllers, battery packs, off-grid inverters, DC loads and AC loads.
(1) Solar cell components
Solar cell components are the main part of the solar power supply system and the most valuable component in the solar power supply system. Their function is to convert the sun's radiation energy into DC electrical energy;
(2) Solar charge and discharge controller (also called "photovoltaic controller")
Solar charge and discharge controller is also called "photovoltaic controller". Its function is to regulate and control the electric energy generated by solar cell components, charge the battery to the maximum extent, and protect the battery from overcharge and over-discharge. effect. In places with large temperature differences, photovoltaic controllers should have temperature compensation functions.
(3) Battery pack
Store the electricity generated by solar modules during the day for use when there is no light.
(4) Off-grid inverter
Off-grid inverter is the core component of the off-grid power generation system, responsible for converting DC power into AC power for use by AC loads. In order to improve the overall performance of the photovoltaic inverter power generation system and ensure the long-term stable operation of the power station, the performance indicators of the inverter are very important.
Application scenarios
Off-grid photovoltaic power generation systems can be used in a wide range of applications, including remote mountainous areas, powerless areas, islands, communication base stations and street lights.
It can also be used on the roofs of villas, residential buildings, schools, hotels, factories, etc.; as well as RVs and yachts, street lights, monitoring power generation systems, photovoltaic building integration, photovoltaic water pump irrigation systems, wind and solar complementary power generation and other fields, which can effectively solve the problem of shortage. Problems caused by electricity, power outages, etc.
