This electrical system was built and installed for a county application in Southwestern Colorado as part of a project to improve emergency communications in the area. The site is located 9700’ in elevation up a narrow and steep ATV path. An 800mZ repeater radio is the major load on-site with additional DC and AC power provided for local emergency service – fire, rescue and police – communication.
The combined load of all the communications systems is just over 50kWh per day – roughly equivalent to the electrical demands of two “average” grid connected homes. Not surprisingly the mandate for this electrical system was “extreme reliability” so two sources of power generation are available at the Grassy Mountain site. A 13.86kW PV array is the prime source of energy and it is backed up by a 20kW diesel generator. View more on Grassy Mountain
