Difference with PWM controller :

PWM uses the digital output of the microprocessor to control the analog circuit. It adopts three-phase charging methods: strong charging, balanced charging, and floating charging. The PWM solar controller solves the problems of unsatisfactory battery charging and short battery life, but the solar panel is not fully utilized.

MPPT solar controller refers to a solar controller with "Maximum Power Point Tracking" function. MPPT solar controller can detect the voltage and current of the solar panel in real time and continuously track the maximum power (P = U * I) , Make the system always charge the battery with the maximum power, MPPT tracking efficiency is 99%, the entire system power generation efficiency is as high as 97%, and the battery charging phase is divided into MPPT charging, constant voltage equalization charging and constant voltage floating charging phase.There are 2 LED lights on the MPPT controller, which are red and green. The red light means the battery is dead. Compared with the traditional solar system, the solar system with MPPT controller will increase the efficiency by 30-50%.The green light means it is fully charged. Real-time monitoring of load charging current, longer battery life.
