Solar Regulator SOLARFAM MPPT MPJ30A 12-24V/30A

Product detailed description

The MPPT regulator uses an internal converter to adjust the V-A characteristic of the current source - solar panel - so that it is optimal for charging the battery. It can thus utilize the energy from solar panels far better than a PWM regulator, which regulates charging only by pulse limiting of the direct connection between the solar panel and the battery, where the pulse width is proportional to the state of the battery being charged. In other words, the MPPT regulator can generate the ideal voltage and current for charging the battery from a higher voltage and lower current of the source. E.g. from 30V and 5A it generates approx. 15V and 10A. The conversion efficiency of the V-A characteristic is usually over 95%, so losses are minimal and the regulators can generally be adapted to different types of batteries so that charging is as optimal as possible.
