Morningstar's SunSaver MPPT solar controller with TrakStar Technology™ is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems. The controller features a smart tracking algorithm that maximizes the energy harvest from the photovoltaic system 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. Its charging process has been optimized for long battery life and improved system performance. This product is epoxy encapsulated for environmental protection, and may be adjusted by the user via four settings switches or connection to a personal computer. The SS-MPPT-15L can also be used with an optional remote meter and battery temperature sensor.
