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 encapsulateed 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.

The SunKeeper is available in a 6 amp or 12 amp version (both at 12 volts DC). To withstand the high temperatures at the solar module, the controller has been designed using extremely efficient power electronics and is rated to 70oC. The SunKeeper is also certified for use in Class 1, Division 2, hazardeous locations, making it an ideal controller for solar powered oil/gas applications.
