The main difference is in how they regulate the charging process. MPPT controllers track the maximum power point of the solar array to extract the most power, while PWM controllers simply regulate the voltage to the battery. Can read on MPPT VS PWM for more information.
PWM controllers are cost-effective, simple to use, and reliable. They are suitable for smaller solar power systems and are generally more affordable compared to MPPT (Maximum Power Point Tracking) controllers.
Yes, PWM controllers are compatible with various types of batteries, including lead-acid, gel, and AGM (Absorbent Glass Mat) batteries. They are designed to adjust the charging parameters based on the connected battery type.
