operating parameters.
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.
Extensive Electronic Protections
Fully protected against most system errors and faults.
Longer Battery Life
Efficient MPPT tracking and 4-stage charging increases
battery life.
Maximizes Energy Harvest
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
Use of High Voltage Modules
Enables the use of high voltage and thin film modules
for off-grid battery charging.
Higher Voltage PV Arrays
Provides a means to use a higher voltage PV array to
charge either a 12V or 24V 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.
Load Control
Automatically disconnects loads when the battery has
been discharged to a low state of charge.
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.
