SS-MPPT-15L
The Morningstar SS-MPPT-15L SunSaver solar controller with TrakStar Technology is an advanced Maximum Power Point Tracking (MPPT) battery charger designed for off-grid photovoltaic (PV) systems. With a maximum current rating of 15A and a voltage rating of 75VDC, this controller maximizes energy harvest from solar panels while providing load control to prevent over-discharge of the battery.
The Morningstar SS-MPPT-15L SunSaver MPPT Charge Controller is suitable for both professional and consumer solar energy applications, including automatic lighting control. Its charging process is optimized for long battery life and improved system performance. With TrakStar MPPT technology, it converts 36V or 24V arrays to charge 12V or 24V batteries, making it versatile and cost-effective.
The TrakStar MPPT technology features a peak efficiency of 97.5%, recognizes multiple power peaks during shading or mixed PV arrays, and performs exceptionally well even at low solar insolation levels. Its efficient MPPT tracking and four-stage charging increase battery life.
The SS-MPPT-15L supports higher voltage PV arrays and thin film modules, enabling the use of high-voltage systems for off-grid battery charging. It also offers load and lighting control, with programmable timer sequences for PV lighting applications.
The controller is fully adjustable via on-board preset switches or customized with a PC connection. It offers USB and RS-232 connectivity for laptop compatibility and advanced automatic custom programmable lighting control. Monitoring is available with status LEDs, an optional meter, and internal data logging of key PV system operating parameters.
