Tips: Solar Charge Controller Types

Solar charge controller can be divided into PWM and MPPT solar charge controllers according to the charging method.

PWM (Pulse-Width Modulation) is used to control the analog circuit via the digital output of the microprocessor. The PWM solar charge controller usually adopts 3-stage charging mode. It solves the problem of battery charge not fully charging, short battery life. Nowadays, the technology of PWM charge controllers is very mature and the price is low. However, the amount of power generated of PV system will be lower than the value we originally designed, so that the solar panel is not fully utilized.

MPPT solar charge controller, refers to the charge controller with "Maximum Power Point Tracking" function. MPPT solar charge controller can detect solar panel voltage and current in real time, and continuously track the maximum power (P = U * I). Thus, it makes the system always charge the battery with maximum power. The MPPT tracking efficiency is up to 99%, and the whole system power generation efficiency is as high as 97%. Although it is priced higher than PWM solar charge controller, MPPT solar charge controller is best choice to replace the PWM in terms of technology and energy savings.
