Boost MPPT Regulator is a kind of solar panel voltage regulator that adopts MPPT Charge and has Voltage Boost Charge Function.
Boost Charge Controller is able to charge a higher battery bank with Lower voltage Solar Panels.
MPPT Regulator has the ability to harvest 30% more power from the solar panels compare to the PWM Regulators. Check the MPPT vs PWM Regulator Comparison Guide.
