Morningstar’s SunKeeper solar controller provides a low cost regulated output directly from the solar module to maximize battery life in small solar power applications. The SunKeeper is epoxy encapsulated and rated for outdoor use. By mounting directly to the module junction box and wiring through the junction box knockout, the connection is weather-proof. This eliminates the need for an additional housing for the controller. It’s designed to mount in a ½” knockout in a PV module junction box or other enclosure.
The SunKeeper is available in 6A or 12A versions for small 12 VDC systems, and provides PWM 3-stage charging. Includes temperature compensation at the controller or alternatively at the battery when used with the optional Remote Temperature Sensor. Able to charge a zero voltage battery. A bi-color LED indicates solar charging, regulation, normal nighttime operation, and any controller or system faults.
The SunKeeper has been designed with extremely efficient power electronics and is rated to 70°C so it can be mounted behind a PV module. The SunKeeper is also certified for use in Class 1, Division 2 hazardous locations, making it well-suited for solar powered oil/gas applications. 5-year warranty. Listed to UL 1604 and CSA 22.2.
