The Phocos CIS-MPPT 85/20 is a 20A charge controller for either 12V or 24V systems. With innovative maximum power tracking technology, this Phocos MPP (Maximum Power Point) tracker ensures maximum performance and yield from all types of solar systems - year-round, in any weather, and in any environment. The use of MPPT technology can contribute to a considerable boost in energy output from PV modules (up to 30% more). At the same time, the temperature-compensated, three-stage I-U curve charge control algorithm significantly extends battery lifespan.
