SunSaver Review

The Morningstar SunSaver Charge Controller offers many of the advantages of the ProStar for smaller systems, at a reduced cost. 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. They have LED charging and load control LVD (low voltage disconnect) indicators in LVD models.
