Morningstar SunSaver MPPT Controller 15L. 15A, 12V 200W / 24V 400W (SS-MPPT-15L)

Sale price$585.00


The Morningstar SunSaver MPPT with TrakStar technology is an advanced maximum power point tracking controller for off-grid solar systems up to 400Wp


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

Use of High Voltage Modules

Enables the use of high voltage and thin film modules for off-grid battery charging.

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.

Automatic Lighting Control

Up to four programmable timer sequences for PV lighting applications.

Smaller Size

Mechanical dimensions are less than other MPPT controllers, making it easier to install in equipment enclosures.

Highly Reliable

Efficient electronics, a conservative thermal design and tropicalization result in high reliability and long life.

Fully Adjustable

User selection via on-board switches or PC connection.

Extensive Electronic Protections

Fully protected against most system errors and faults.

Longer Battery Life

Efficient MPPT tracking and 4-stage charging increases battery life.

More Information

The status LED’s and optional meter provide extensive controller and system data.

Data Logging

Records key operating parameters of the PV system and includes 30 days of data logging.
