    Morningstar SunSaver 15A Charge Controller

    The SunSaver MPPT (Maximum Power Point Tracking) charge controller is designed for 12 and 24 VDC battery charging from a PV array with a maximum open circuit voltage of 75 VDC. Use up to three 36-cell PV modules in series or a single 60-cell or 72-cell module to provide up to 200 W when charging a 12 VDC battery or up to 400 W when charging a 24 VDC battery. The SunSaver MPPT maximizes the output of the PV array by rapidly finding the array’s peak power point with extremely fast sweeping of the entire I-V curve, providing an estimated 5-25% power boost over PWM or simple on-off controllers, especially during periods of colder temperatures and low battery voltages when it is most needed.

    The controller features electronic protection from short circuit, overcurrent, reverse polarity, high temperature, high voltage, lightning, and transient surges. An adjustable low-battery load disconnect protects the battery from over-discharge. LED indicators indicate charging, low-battery and faults. The optional meter provides detailed system information, 30 days of logged data, alarms, and faults.

    The SS-15MPPT has a simple DIP-switch setup for plug-and-play operation or is fully programmable for custom and advanced programming with a PC connection using the PC MeterBus Adapter (MSC) and Morningstar’s MSView software (available for free on Morningstar’s website). Also compatible with Morningstar’s MeterHub. The UMC-1 communications adapter converts the Morningstar MeterBus RJ-11 electrical interface to a standard USB 2.0 interface which allows communication between a Morningstar charge controller or inverter and a PC computer. See the Morningstar Accessories page for information on the metering and other accessories for this controller.

    The SunSaver MPPT now features programmable lighting control for up to four time periods and is adjustable with respect to hours/minutes after/before – Dusk/Dawn/Solar Midnight/Solar Noon. Mounts on DIN rail with DIN-1 rail clip.

    SS-15MPPT dimensions are 6.6"H x 2.75"W x 2.2"D, weight is 1.65 lbs, and it is covered by a 5-year warranty. Listed to UL 1741 CSA 107.1 for U.S.A. and Canada.
