SMA has expanded the capacity of its Sunny Tower inverter system, which is designed for commercial-scale PV arrays, to include 30 kW through 48 kW configurations. With the Sunny Tower, solar professionals can now install any combination of SMA Sunny Boy 5000-US, 6000-US, 7000-US and 8000-US inverters to create a custom power output based on the overall PV system design, the company explains.
These Sunny Boy models are certified to UL and CSA standards and meet domestic-content requirements for the U.S. and Canada.
‘The ability to mix and match Sunny Boy inverters with the Sunny Tower increases design flexibility while providing leading reliability and world-class efficiencies,’ says Jurgen Krehnke, president and general manager of SMA America and president of SMA Canada. ‘It also allows installers to apply their existing experience and tools in the residential market to attract commercial-grade projects.’
In addition to providing design flexibility and an increased energy harvest, the Sunny Tower allows installers to apply a decentralized approach to commercial systems – which results in less labor, reduced DC cabling, and lower operation and maintenance costs, according to the company.
