Technologies of Charge Controller - Charge controllers have two different types

MPPT Charge Controller (Maximum Power Point Tracker)
PWM Charge Controller (Pulse Width Modulation)

Solar battery charge controller comes in two different types. One is MPPT (Maximum Power Point Tracker) and the other one is PWM (Pulse Width Modulation). Both the charge controllers do same work as they control the passing current in to battery and load, but with different methods. Let’s understand their working methods and the difference between the two.

MPPT Charge Controller
Maximum power point tracker charge controller converts the passing voltage into battery voltage. MPPT solar controller also increase the current when voltage drops.

This power controller extracts maximum power from solar panel and charges battery effectively. MPPT charge controller can give us 96W out of 100W of solar panels. Which means its efficiency is 96-97%.

PWM Charge Controller
Pulse width modulation charge controller only utilize the power generating from solar panels and charge the battery. In this charge controller current passes into the battery in the form of solar pulses. It can provide up to 70W of power out of 100W solar power panel.
