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.
Mechanical dimensions are less than other MPPT controllers, making it easier to install in equipment enclosures.
Efficient electronics, a conservative thermal design and tropicalization result in high reliability and long life.
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.
The status LED’s and optional meter provide extensive controller and system data.
Records key operating parameters of the PV system and includes 30 days of data logging.
