MPPT controller is the full name of "Maximum Power Point Tracking" (MPPT) solar controller, is the traditional solar charge and discharge controller upgrade products.

MPPT controller can detect the power generation voltage of solar panels in real time, and track the highest voltage and current value (VI) to make the system charge the battery with maximum power output. It is applied in solar PV system to coordinate the work of solar panel, battery and load, and is the brain of PV system.
