Differences between PWM and MPPT type photovoltaic charge controllers:

MPPT T40 charge controllers installed in autonomous photovoltaic systems determine the appropriate charging levels for the batteries, creating operating conditions for the photovoltaic systems while providing limited to minimal losses in their actual performance.

A simple conventional PWM charge controller distributes the energy produced by the photovoltaic panel to the batteries at about 85%, while the remaining energy of about 15% is lost.

The MPPT T40 controller detects the maximum power point of the photovoltaic at every moment. This means that through the controlling electronic circuit it possesses, it converts the potential difference of the photovoltaic panel (voltage) in relation to the battery voltage into current while simultaneously distributing all the generated energy to the battery.

With this process, we utilize approximately 96% of the energy produced by the photovoltaic panel compared to the 80% of the energy we utilize from a PWM type charge controller.
