Off Grid Inverter PV Power Generation System
Off-grid photovoltaic power stations, also known as independent photovoltaic power stations, are power generation systems that operate independently of the grid, mainly composed of solar panels, energy storage batteries, charge-discharge controllers, inverters and other components. The electricity from the solar panel directly flows into the battery and is stored. When it is necessary to power the electrical appliances, the DC current in the battery is converted into 220V AC through the inverter.
This is a repeated cycle of charging and discharging process. This power generation system is widely used because it is not limited by regions. It can be installed and used as long as there is sunlight. Therefore, it is very suitable for remote areas without power grids, isolated islands, fishing boats, outdoor breeding bases, etc., and can also be used for emergency power generation in areas with frequent power outages.
This system has to be equipped with battery, and accounts for 30-50% of the cost of the power generation system. Moreover, the service life of the battery is generally 3-5 years, and it has to be replaced later, which increases the service cost. In terms of economy, it is difficult to popularize and use it on a large scale, so it is not suitable for use in places where electricity is convenient.
However, it has strong practicability for families in areas without power grid or areas with frequent power failure. Especially to solve the lighting problem in case of power failure, DC energy-saving lamps can be used, which is very practical. Therefore, off-grid power generation system is specially designed for use in areas without power grid or areas with frequent power failure
