Photovoltaic power plant meteorological station

The photovoltaic power plant meteorological station battery is used to store electrical energy and is a sealed battery suitable for outdoor environments. It has sufficient capacity and can provide stable power supply for equipment on continuous rainy days (3-7 days), avoiding equipment shutdown due to lack of light on cloudy days; The charging controller is responsible for controlling the charging and discharging process, preventing overcharging and overdischarging of the battery, extending its service life, and ensuring the stability of the power supply system.

1Photovoltaic power plant meteorological stationScope of application

Distributed photovoltaic power generation refers to the photovoltaic power generation facilities that are built and operated at or near the user's site, with the user's self use as the main feature, excess electricity connected to the grid, and balanced and regulated in the distribution network system.

In order to ensure the normal operation and data analysis of photovoltaic power plants, it is usually necessary to equip a distributed photovoltaic power generation environment monitoring system to monitor indicators such as total solar radiation, surrounding environmental temperature, wind speed and direction, and photovoltaic module temperature.

The distributed photovoltaic power generation environmental monitoring system can be connected to the monitoring system, which displays, records, and analyzes the data of the environmental monitoring system. It can also be connected to the inverter control system, which analyzes the sensor data to ensure the effective operation of the photovoltaic power station.
