SMA Unveils Inverter Solution to Commercial Rooftop PV Systems

published: 2014-11-13 15:31 | editor: | category: News

SMA has introduced a fully integrated, preassembled and prewired roof-mount racking solution for commercial-scale PV called the ReadyRack™. The new design, for use of Sunny Tripower TL-US, can be assembled in minutes, simplifying and speeding project completion. It also is fully UL and NEC 2014 compliant.

With Sunny Tripower’s OptiCool temperature management system and special-designed components, the SMA ReadyRack is easier to install. The new solution is also easy to transport because it is completely collapsible for reduced shipping costs and can be stacked to maximize shipping density. It also features rugged steel tubing, adjustable settings that are lockable as low as 15 degrees and a 10-year warranty. Most importantly, the SMA ReadyRack meets UL and NEC 690.12 rapid shutdown requirements when placed within 10 feet of the PV array. Combined with SMA’s arc-fault technology, the SMA ReadyRack provides optimum commissioning and operation of commercial-scale PV.

Henry Dziuba, president and general manager of SMA America and president of SMA Canada, said, “The ReadyRack and Sunny Tripower are a powerful combination, offering design flexibility, high efficiency, enhanced safety and full grid management features, providing installers with a comprehensive commercial-scale system solution.” 

The Sunny Tripower TL-US—available in 12, 15, 20 and 24 kW models—boasts peak efficiency of more than 98% while its OptiTrac™ Global Peak maximum power point (MPP) tracking algorithm further maximizes energy production by minimizing the effects of shade. It is suitable for both 600 VDC and 1,000 VDC applications and offers two independent MPP trackers, a combined or detached connection unit, and myriad mounting configurations, further increasing design flexibility.

Safety and reliability have been enhanced with the Sunny Tripower TL-US due to its all-pole ground fault protection, integrated AFCI, and DC monitoring per MPPT, granular down to four strings. It also delivers a future-proof solution with full grid management features—including power factor correction, low-voltage ride through, curtailment and frequency response—and innovative monitoring and communications features allowing start/stop/reset remote capability, as well as SMA Service, technical support and system-wide O&M availability.
