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

Product detailed description

The MPPT controller uses an internal inverter to adjust the V-A characteristic of the current source-solar panel to be optimal for battery charging. It can thus harness the energy from the solar panels far better than a PWM controller, which regulates charging only by pulse limiting 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 controller can generate the ideal voltage and current for charging the battery from a higher voltage and lower current source. For example, from 30V and 5A it will generate about 15V and 10A. The conversion efficiency of the V-A characteristic tends to be above 95%, so the losses are minimal and the regulators can usually be adapted to different types of batteries to provide the most optimal charging.
