MorningStar - SS-MPPT-15L - SunSaver MPPT

Morningstar’s SunSaver MPPT Solar Controller with TrakStar Tehnology™ is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems. The controller features a smart tracking algorithm that maximises the energy harvest from the PV and also provides load control to prevent over-discharge of the battery.

The SunSaver MPPT is well suited for both professional and consumer PV applications including automatic lighting control. Its charging process has been optimised for long battery life and improved system performance. This product is epoxy encapsulated for environmental protection, may be adjusted by the user via four setting switches or connection to a personal computer, and has an optional remote meter and battery temperature sensor.
