This installation by Onsite Energy was the first 1000 Volt solar array installed in Montana, closely following the adoption of the 2011 NEC standards by the state. The power from the solar array is converted to three-phase 480-Volt AC power by an Aurora
Power-One 24 kW transformerless inverter, seen below. The system is projected to produce 35,660 kWh annually, and
is estimated to offset 80% of the energy demand of two agricultural pivot pumps on this Roundup ranch.
