The solar energy control system consists of solar panels, batteries, controllers and loads.
Solar controller is a device used to control photovoltaic panels to charge batteries and provide load controlled voltage for voltage sensitive devices. It regulates and controls the charging and discharging conditions of the battery, and controls the output of the solar cell module and the battery to the load according to the power demand of the load. It is the core control part of the whole solar power supply system. It is specially designed for the power supply system of telecom communication or monitoring equipment in remote areas. The charge control and load control voltage of the controller are fully adjustable, and the battery voltage, load voltage, solar array voltage, charge current and load current can be displayed.
Almost all solar power systems powered by batteries need a solar charge and discharge controller. The function of the solar charge and discharge controller is to regulate the power from the solar panel to the battery. Battery overshoot, at least significantly reduces battery life, and at worst damages the battery until it fails to function properly.
Solar controller adopts high-speed CPU microprocessor and high-precision A/D analog-to-digital converter. It is a microcomputer data acquisition and monitoring control system. It can not only collect the current working status of PV system in real time, get the working information of PV station at any time, but also accumulate the historical data of PV station in detail, which provides an accurate and sufficient basis for evaluating the rationality of PV system design and testing the reliability of system components. In addition, the solar controller also has the function of serial communication and data transmission, which can centralize the management and remote control of multiple photovoltaic system sub-stations. The solar controller usually has 6 nominal voltage levels: 12V, 24V, 48V, 110V, 220V and 600V. At present, the controller is developing towards multi-function. There is a tendency to integrate traditional control parts, inverters and monitoring systems.
