Morningstar SunSaver SS-10-12V Solar Charge Controller (Gen 3)

The Morningstar SunSaver SS-10-12V is a very reliable charge controller with the same battery charging algorithm as the ProStar that has been scaled down for smaller PV systems. This device includes a combination of features and capabilities not found in other small PV controllers.

This controller is rated for Hazardous Locations – Class 1, Division 2 (C1 D2 - Class I Div II) Groups A-D, making it the preferred choice for Oil & Gas applications. Class I, Division 2 certification permits use of an electrical device in an environment where explosive gases are periodically present. The Morningstar SunSaver SS-10-12 is C1D2 certified for systems that are properly wired per Division 2 NEC approved wiring methods.

Constant voltage PWM charging is a proven advancement compared to the common on/off PV regulators. SunSavers are field-selectable for sealed or flooded batteries. A rugged anodized aluminum case and epoxy-encapsulated electronics ensure durability and longevity. A temperature compensation sensor in the charge control varies full charge voltage with temperature. All Morningstar SunSaver controllers feature LED charging indicators.

SunSaver SS-10-12V Benefits

The SunSaver 10 features 4-stage PWM battery charging for optimum battery health.
