SMA America and SMA Canada are now securing orders for their medium-voltage turnkey power solutions, which include the SMA MV Power Platform—available as an open or shaded structure—and SMA MV Power Station. They join the Sunny Central High Efficiency (HE) and award-winning Compact Power (CP) lines of solar inverters in SMA’s North American utility-scale lineup.

The company’s 1.0-1.6 MW medium-voltage turnkey power solutions include two Sunny Central inverters; a medium-voltage transformer; optional DC or AC/DC disconnect cabinets; and a control and supply panel for power distribution to local loads and (optionally) field tracker motors. They also feature easy integration with installer SCADA equipment; a modular, steel base with all component interconnection cabling; and a convenient plug-and-play installation scheme. Designed for Seismic Zone D applications, all configurations can be deployed in temperatures to -40 C, making them suitable for the Canadian solar market and other cold regions. SMA offers a variety of service and warranty options, including a 99% uptime guarantee.

“By pre-engineering and assembling the MV Power Platform and MV Power Station, SMA offers EPCs and utility companies a cost-effective way to modularly install large-scale PV power converters,” says Jurgen Krehnke, president and general manager of SMA America and president of SMA Canada. “Packaging SMA’s industry-leading technology into a factory-integrated solution reduces costs, optimizes performance and improves the speed of plant installation and commissioning.”

Available grid management features include control of active and reactive power; automatic over-frequency response; power factor adjustment; power curtailment; and low voltage ride through. SCADA connectivity via Modbus and the SMA OPC Server ensure optimum communication and control.

Designed with delivery in mind, the MV Power Platform and MV Power Station can be transported via a standard semi-truck and unloaded by crane. Each configuration then can be installed on a concrete slab, vault or piers for maximum flexibility.

SMA’s MV Power Platform and MV Power Station are assembled in regional facilities throughout North America.

Also included in the company’s utility-scale product portfolio are the Sunny Central CP and HE inverter lines. The Sunny Central CP line includes the Sunny Central 500CP, 630CP, 720CP, 760CP and 800CP, which won the Intersolar Award 2010 in the photovoltaics category. The outdoor-rated Sunny Central CP inverters produce 110% of rated output at temperatures below 25 C, resulting in increased yields and a lower levelized cost of energy. Meanwhile, the Sunny Central HE line—which consists of the UL-Listed Sunny Central 500HE-US/CA, as well as the Sunny Central 630HE—boasts an industry-leading maximum efficiency of 98.6%.
