Morningstar SunSaver SS-MPPT-15L MPPT Charge Controller

Morningstar's SunSaver MPPT solar controller with TrakStar Technology™ is an advanced maximum power point tracking (MPPT) battery for off-grid photovoltaic (PV) systems with PV array max power (Pmp) up to 520 watts. 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. Detailed battery programming options allow for advanced battery support for the latest Lithium, Nickel Cadmium, and Lead Acid battery types. 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.

Features

• Designed for harsh environments and hazardous locations around the globe
• 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 12 or 24 V 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
• 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
