The main function and use of solar controller

(Summary description)The solar controller is mainly used for photovoltaic modules to charge the battery. It can stabilize the voltage during the charging and discharging process and avoid device damage caused by overcharging. Therefore, the full name of the controller is also called the solar charge and discharge controller, which is divided into MPPT solar controller and PWM solar controller.

Information

The solar controller is mainly used for photovoltaic modules to charge the battery. It can stabilize the voltage during the charging and discharging process and avoid device damage caused by overcharging. In addition, the solar controller also has boost, short circuit protection, load protection, coordination of solar panels, lithium batteries, work between loads. Therefore, the full name of the controller is also called the solar charge and discharge controller, which is divided into MPPT solar controller and PWM solar controller.

Friends who know solar energy may have heard or even know about solar controller! The solar controller is an automatic control device used in the solar power generation system to control the multi-channel solar cell array to charge the battery and the battery to supply power to the solar inverter load. It regulates and controls the charging and discharging conditions of the battery, and controls the power output of the solar cell components and the battery to the load according to the power demand of the load. It is the core control part of the entire photovoltaic power supply system.

The basic function of the solar controller is to control the battery voltage and turn on the circuit, when the battery voltage rises to a certain level, stop the battery charging.

Solar controllers are used in most photovoltaic systems to protect batteries from overcharging or overdischarging. Overcharging may vaporize the electrolyte in the battery, causing failure, and overdischarging the battery will cause the battery to fail prematurely. Overcharging and overdischarging may damage the load, so the controller is one of the core components of the photovoltaic power generation system, and it is also a balancer. main part of the system.

In short, the role of the solar controller can be divided into:

1. Power adjustment function.
2. Communication function: simple instruction function and protocol communication function, wireless and other forms of background management.
3. Perfect protection functions: electrical protection, reverse connection protection, short circuit protection, overcurrent protection, overcharge protection, overdischarge protection, etc.
