Morningstar SS-MPPT-15L SunSaver MPPT 15 Amp 12/24 Volt MPPT Charge Controller Includes LVD Override Protection

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.

• 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

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

• Provides a means to use a higher voltage PV array to charge either a 12V or 24V battery.

• 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.

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

• USB MeterBus Adapter for laptop compatibility
• PC MeterBus Adapter for RS-232
• Fully adjustable user selection via on-board preset switches or customized with PC connection
• Advanced automatic custom programmable lighting control with a PC connection
• Extensive controller and system data is provided by the status LED’s and optional meter. Monitoring is also available with a personal computer
• 30 days of internal data logging of key PV system operating parameters
• Excellent performance at low solar insolation levels

• 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.

• Fully protected against most system errors and faults.

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