Sadly, the panel was a commercial unit, and compatible off-the-shelf MPPT, or maximum power-point tracking, controllers are expensive. His solution was to build his own controller using a cheap DC ...

PWM controllers have a typical efficiency of less than 80%. MPPT solar charge controllers are also known as smart DC-to-DC converters, and they are more advanced than PWM controllers. An MPPT ...

However, the secret weapon behind maximizing the efficiency of these panels often goes unnoticed: the MPPT solar charge controller. At the intersection of technology and sustainability ...

They are better than simple charge controllers because they more closely monitor the battery state between each pulse, allowing batteries to reach closer to maximum capacity and maintain more capacity ...
