Product Feature

With innovative maximum power point tracking technology, this Phocos MPP tracker ensures maxiumum performance and yield from a variety of solar systems.

The use of MPPT technology can contribute to a considerable boost in power output from PV modules (up to 30% more). Especially in moderate/colder climate areas where PV module voltages tend to be higher. At the same time, the temperature-compensated, three-stage I-U curve charge control algorithm significantly extends battery lifespan.

The integrated datalogger (2 years period) provides an insight into system performance, displaying important information such as system status, voltage, current, SOC, etc.
