Sun Saver MPPT Solar Regulator

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 PV 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 including automatic lighting
control. Its charging process has been optimized for long battery life and improved system performance. This product
is epoxy encapsulated for environmental protection, may be adjusted by the user via four settings switches or
connection to a personal computer, and has an optional remote meter and battery temperature sensor.

Our 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
• 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.
• Automatic Lighting Control
• 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.
• Efficient MPPT tracking and 4-stage charging increases battery life.
• Data Logging
