Morningstar SS-MPPT-15L SunSaver 15 Amp MPPT Solar Charge Controller

SunSaver MPPT


The SunSaver MPPT™ with TrakStar technology is the perfect charging solution for smaller off-grid solar systems up to 400Wp. An industrial-grade design proven in challenging applications and environments, SunSaver has been called the single most successful charge controller in the solar industry.


Key features and benefits

  • Maximum power point tracking (MPPT) optimally matches the solar array to the battery—no wasted PV electricity.
  • Use of high voltage modules – In addition to 12V crystalline modules,
    enables use of high voltage modules for off-grid battery charging.
  • Converts 36V or 24V arrays for use with either a 24V or 12V battery.
  • Automatic Lighting Control – four programmable timer sequences for PV lighting applications using MSView.
  • Extensive electronic protections include short-circuit, over-current and reverse polarity to ensure the controller will not be damaged by wiring mistakes or overloads.
