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.

Controller Features:

  • Maximizes Energy Harvest
    TrakStar MPPT Technology features:
    • Peak efficiency of over 97%
    • Almost no power losses
    • Recognition of multiple power peaks during shading or mixed PV arrays
    • Excellent performance at low solar insolation levels
  • Converts 36V or 24V PV Arrays
    Provides a means to use up to a 36V PV array to charge either a 24V or 12V battery.
  • Lower System Cost
    Less expensive than other MPPT controllers and is affordable in smaller PV systems up to 400Wp. Allows system costs to be reduced by down-sizing the PV array, using on-grid or thin film modules and decreasing cable sizes.
  • Use of High Voltage Modules
    Enables the use of high voltage and thin film modules for off-grid battery charging.
  • Includes Load Control
    Automatically disconnects loads when the battery has been discharged to a low state of charge.
  • Longer Battery Life
    Efficient MPPT tracking and 4-stage charging increases battery life.
  • Data Logging
    Records key operating parameters of the PV system and includes 30 days of data logging.
  • Diversion Control Capability
    May be programmed to control charging using an auxiliary DC resistive load.
  • Advanced Lighting Control Capability

Please Note:

The SunSaver MPPT can accept 12V , 24V, or 36V nominal off-grid solar module arrays. The solar array nominal voltage must be equal to or greater than the nominal battery voltage. For 24V systems, a 24V or 36V nominal solar array must be used. Grid-tie solar module(s) may be used with the Sunsaver MPPT if the open circuit voltage (Voc) does not exceed the SS-MPPT 75 V maximum solar input rating.
