4.What is MPPT technology?

MPPT or Maximum Power Point Tracking is algorithm that included in charge controllers used for extracting maximum available power from PV module under certain conditions. The voltage at which PV module can produce maximum power is called 'maximum power point' (or peak power voltage).

The maximum power point tracking (MPPT) is a higher efficient DC-DC converter technology compared to "shunt controller" and "pulse width modulation (PWM)" technologies.

Using a non-MPPT charge controller is like connecting the battery directly to the solar module. A traditional charge controller may charge a battery with the voltage that is dictated by battery. By nature, the voltage of a fully-charged battery is higher than that of a discharged-battery. Consequently, the power drawn by an empty battery is usually lower than that of a full battery. 

The question arises, when we notice that there is a power loss that we are not utilizing when our batteries are empty. Where did my power go?

The MPPT utilizes whole module power by dictating the voltage of the battery charging state. The charge controller keeps the voltage and current at an optimized level where the modules deliver the most juice.
