As NEC 2014 codes change and inverters must be elevated off of the roof, some inverter manufacturers are offering their own racking systems.
For example, the SMA ReadyRack is designed for its three-phase inverter, the Sunny Tripower TL-US. The SMA ReadyRack allows for a simplified installation that includes all balance of system components, such as the AC disconnect, combiners, cables and more. As its name states, the ReadyRack can be installed within minutes on flat commercial rooftops. It’s ideally designed for mounting within 10-feet of the PV array to comply with the NEC 690.12 rapid shutdown requirements. Experience a simpler, faster commercial install with the ReadyRack.
“The SMA ReadyRack is the fastest, easiest way for installers to deploy decentralized, commercial rooftop systems,” said Henry Dziuba, president and general manager of SMA America and president of SMA Canada. “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 kilowatt 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.
