MPPT Solar Charge Controller for Efficient Battery Charging is latest conceptAn MPPT as we all know refers to maximum power point tracking which is typically associated with solar panels for optimizing their outputs with maximum efficiency. In this post we learn MPPT controller for harnessing solar power and charging a battery in the most efficient manner.
Where an MPPT is Used
New hobbyists normally find the concept to difficult and get confused with the many parameters associated with MPPT, such as the maximum power point, “knee” of the I/V graph etc.
The optimized output from MPPT circuits is primarily used for charging batteries with maximum efficiency from the available sunshine.
And that’s why we require an intermediate device such as an MPPT which can “understand” these variations and churn out the most desirable output from a connected solar panel.
The basic idea behind all MPPTs is to drop or trim down the excess voltage from the panel according to the load specs making sure that the deducted amount of voltage is converted into an equivalent amount of current, thus balancing the I x V magnitude across the input and the output always up to the mark…we cannot expect anything more than this from this useful gadget, do we?
The above automatic tracking and appropriately converting the parameters efficiently is implemented using a PWM tracker stage and a buck converter stage, or sometimes a buck-boost converter stage, although a solitary buck converter gives better results and is simpler to implement.
