Yellowstone National Park operates the Bechler Ranger Station from late May to early November. This remote outpost accommodates six to eight park rangers and functions as a contact station for visitors entering the backcountry. In 2011, the park constructed a mobile system with 32 280-W multi-silicon PV modules, 2,500 amp hours of battery storage at 48 volts, a 183-amp charge controller, and three inverters, totaling 18 kW of capacity.

A case study about Bechler Ranger Station in Yellowstone National Park is also available.
