Solar controller MPPT SOLARFAM MPJ40A, 12-24V/40A

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. Thus, it can utilize the energy from the solar panels much better than a PWM controller, which regulates charging only by pulse limiting the direct connection between the solar panel and the battery, with the pulse width 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 30 V and 5 A it will generate about 15 V and 10 A. The conversion efficiency of the V-A characteristic is usually above 95%, so losses are minimal and the regulators can usually be adapted to different types of batteries to provide the most optimal charging.

CV-boost = charging for 1-2 hours after clamp voltage reaches 14-15 V (adjustable)
CV-equalize = charging with increased voltage to mix the liquid electrolyte - optional for liquid electrolyte batteries only
CV-float = charging with a holding voltage of 13.5-13.8 V (adjustable)
Choice of battery type: liquid dielectric, AGM, AGM GEL, LiFePO4
LCD display for setting and monitoring operating parameters
