Off grid photovoltaic power plants are facilities that utilize solar energy for power generation, which do not rely on the power grid, operate independently, and store electrical energy. These stored electrical energy can be used during peak electricity demand to meet local electricity demand and reduce dependence on fossil fuels. Off grid photovoltaic power plants have many application areas, such as remote areas, disaster recovery, and special environments. In these places, the use of off grid photovoltaic power plants can greatly improve the quality of life and production efficiency.

Off grid photovoltaic power stations mainly consist of the following parts:

1. Photovoltaic array: The core part of an off grid photovoltaic power station is a photovoltaic array, which is composed of multiple photovoltaic panels. These panels are connected together in series and parallel to form a photovoltaic array that can output a certain amount of power.

2. Inverter: The inverter is an important component of an off grid photovoltaic power plant, which can convert the direct current output from the photovoltaic array into alternating current for integration into the power grid or direct supply to the load.

3. Energy storage system: The energy storage system consists of a battery pack and a battery management system, used to store DC energy and provide power to the inverter when needed.

4. Charging controller: The charging controller is used to control the charging process of the battery pack and protect the battery pack from damage such as overcharging and discharging.

5. Transformer: A transformer is used to increase or decrease the voltage of alternating current to meet the needs of different loads or to be integrated into the power grid.

6. Monitoring system: The monitoring system is used to monitor the operating status of off grid photovoltaic power plants in real time, including the working status of photovoltaic arrays, inverter output, battery pack power, etc., so that maintenance personnel can detect and handle faults in a timely manner.
