Compared to conventional PWM controllers and depending upon the performance characteristics of the solar array, MPPT technology may increase the solar system charge efficiency up to 30% and potentially decrease the required power of the solar array.

Frequently Asked Questions

Should I use an MPPT or PWM controller?

A solar controller is an essential component of a marine solar system. A controller gathers the maximum amount of power from the solar panels and delivers the proper amount of power to the battery bank for efficient charging and ensures the batteries are not overcharged. Pulse Width Modulated (PWM) controllers are excellent for smaller solar systems under 200 watts. They are cost effective and use little power. Our PWM controller is designed for charging two battery banks; ideal for cruising sail and power boats. Maximum Power Point Tracking (MPPT) controllers are designed to pull the maximum power off a solar system and adjust the charging voltage and current to achieve maximum battery charging efficiency. MPPT controllers are ideal for solar systems above 200 watts in rated output.
