The following is a detailed explanation of the working principle of solar photovoltaic controller, mainly including 4 aspects:
(1) Basic composition of solar photovoltaic system:
Solar panels (also known as photovoltaic boards) by absorbing the sun and converting them into DC, this is the starting point of solar power generation. However, the electric energy generated can not be used directly, but a series of regulatory and management of the photovoltaic controller is needed.
(2) The main functions of photovoltaic controller include:
Charging control control the power generated by solar panels to prevent the battery from overloading; control the battery discharge to avoid the battery excessive; when the battery voltage is too low, cut off the load to protect the battery; Sexual countermeasures ensure the safe and stable operation of the system.
(3) In terms of charging control, the photovoltaic controller determines its charging status by detecting the voltage and current of the battery. When the battery voltage reaches a certain value, the controller will limit the output current of the solar panel to prevent the battery from overloading. In terms of discharge control, when the battery voltage is reduced to a certain degree, the controller will automatically cut off the load to avoid the battery storage and ensure the life and performance of the battery.
(4) Photovoltaic controller also has anti -anti -connection protection functions:
When the photovoltaic board or battery is riots, the controller immediately cuts off the circuit to prevent damage and safety accidents caused by rigid reflection.
In general, the working principle of the solar photovoltaic controller is to ensure the stable operation and efficient utilization of the solar power generation system through a series of detection and control measures. It not only manages the battery, but also has a variety of protection functions, making the entire system more secure and reliable. In the solar power generation system, the role of photovoltaic controller cannot be ignored. It is one of the key factors to ensure the long -term stable operation of the system.
