Morningstar SunSaver SS-10L-24 Solar Charge Controller (Gen 3)
The Morningstar SunSaver SS-10L-24 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 SS-10L-24 model features a low voltage load disconnect (LVD). This is often used to turn off small power applications before draining the battery completely. With a relay, this can be used to control a load like an inverter, pump, motor, compressor, or anything else that exceeds the controller’s load current rating.
This controller is rated for Hazardous Locations – Class 1, Division 2 (Class 1, Div 2 - Class I Div II)Groups A-D, making it the preferred choice for Oil & Gas applications. Class 1, Division 2 certification permits use of an electrical device in an environment where explosive gases are periodically present. The Morningstar SunSaver SS-10L-24 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.
