Morningstar SunSaver MPPT Charge Controller


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. 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.

Key Features and Benefits

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.

Diversion Control Capability
May be programmed to control charging using an auxiliary DC resistive load.

Includes Load Control
Automatically disconnects loads when the battery has been discharged to a low state of charge.

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.
