Grid-Connected 13.2 kW Solar Inverter Unveiled

August 11, 2004 [] Solectria Corporation introduced a 13.2 kW photovoltaic (PV) inverter for grid-connected commercial 3-phase PV systems for the North American market. Moving into the growing solar inverter market was a natural extension of the company’s work throughout the past decade on power electronics and control systems. Solectria specializes in the development and manufacturing of a wide range of components for electric, hybrid, and fuel cell vehicles, and for the distributed generation of electric power. The company’s inveter, the PVI13KW, includes both a DC disconnect and a fused AC disconnect, an AC contactor for zero Watt standby loss, an optional built-in 7-fuse PV combiner, a transformer and filter, and a DSP-controlled, trench-gate IGBT inverter core. The unit is fully assembled and tested at Solectria, an ISO 9001:2000 certified manufacturer. It is delivered as a single unit with nothing to connect, assemble, mount or wire other than PV leads and AC connection to the facility’s AC circuit panel. Multiple inverters can be used in parallel for larger PV systems, for example, 4 units for a 52kW (AC) system. The system is designed for indoor or outdoor installations (wall, floor, roof or ground mount) and can be used for other renewable, fuel cell and distributed generation applications. Precision DSP-controlled Maximum Power Tracking Algorithm provides maximum daily energy from PV.
