The solar charge controller mainly controls the photovoltaic panel to charge the battery. In this article, the solar charge controller will be introduced to a certain extent, and I hope it will be helpful to you.
Classification of solar charge controller
All Series of solar charge controller products
The popular solar charge controllers on the market mainly include ordinary solar charge controllers, PWM solar charge controllers and MPPT solar charge controllers.
Ordinary solar charge controller is the first-generation technology. The working principle is to directly connect the output of the solar panel to the battery port, and disconnect it when the battery is full. It is difficult to fully charge the battery due to the internal resistance of the battery, and the solar battery The board is not fully utilized, and the charging conversion efficiency is only 70% to 76%, which has been eliminated by the market, and only a few people using it.
The PWM solar charge controller is the second-generation technology, the most on the market now. The working method is about the PWM control mode. Compared with ordinary solar charge controllers, it has improved a lot and can solve the problem of battery dissatisfaction. The charging conversion efficiency is 75% to 80%, but the solar panels are not being fully utilized.
MPPT solar charge controller is the third generation technology, the most high-end solar charge controller. The MPPT solar charge controller refers to a solar charge controller with "Maximum PowerPoint Tracking" function. It is an upgraded product of the PWM solar charge controller. The MPPT solar charge controller can detect the voltage and current of the solar panel in real time, and continuously track the maximum power (P=U*I). So, that the system always charges the battery with the maximum power. The MPPT tracking efficiency is 99%, and the power generation efficiency of the entire system is as high as 97%. It also has excellent management of the battery. MPPT charging, constant voltage equalizing and constant voltage floating charging. With the advancement of technology and energy conservation, the trend of MPPT solar charge controllers replacing traditional PWM solar charge controllersis irreversible.
The controller used in solar home systems are called solar system controllers. This type of controller simply has the function of battery charging and discharging. Solar street lamp controller have been using in the controllers and solar street lamp projects. In addition to battery charging and discharging functions, this type of controller also has light control and time control functions. It is convenience to turn on and off the street lights automatically at night.
Foshan SNAT Energy Electric Technology Co., Ltd. was established in 2004. It uses solar energy as the main energy sources and adopts high-efficiency fifth IGBT technology. It has lower operating costs, one-time investment, and long-term benefits. The company's main products are: solar generators, solar inverters, solar charge controllers and other solar products. For example, solar charge controllers include CM-MPPT high-voltage solar charge controllers, CM-MPPT solar charge controllers, CP-wall-mounted solar charge controllers, and SCP-PWM solar charge controllers.
