When setting up a solar power system, an MPPT (Maximum Power Point Tracking) solar charge controller can make your system more efficient by converting extra voltage into usable energy for your batteries. MPPT controllers are more advanced than PWM controllers and can increase the efficiency of your solar panels, especially in cloudy conditions or when the panel’s voltage is much higher than the battery’s.
