Energy-management provider Schneider Electric says it will supply nine of its GT500 MVX grid-tie solar inverters to SunEnergy1 for a commercial rooftop solar project at Shoe Show Inc.'s corporate headquarters in Concord, N.C.
The 5.2 MW project was commissioned in January. Shoe Show entered into a power purchase agreement with Duke Energy, which will purchase all of the power generated from the system. The solar installation is projected to generate 6.7 GWh per year, which is enough energy to fully power approximately 600 homes, according to Schneider Electric.
The company's GT500 MVX inverters are designed for large-scale 600 V DC utility power plant applications, but were chosen for this rooftop project because the solar array is tied directly to the utility medium-voltage grid rather than routed through the building's low-voltage distribution system, according to Schneider Electric.
The GT500 MVX incorporates a maximum power point tracking (MPPT) algorithm to maximize the energy harvested from a PV array. The GT500 MVX is suitable for outdoor installation, and the inverter and its sub-components have gone through reliability testing using multiple testing methods, Schneider Electric adds.
