Sunny Boy 1800U

Use this inverter for solar installations with 2kW of modules. With its 120VAC output this unit can be used in residential or commercial settings. Just like every other Sunny Boy Inverter the SWR 1800U can be configured for any of the communications options available. Which means you can combine them with any other SMA inverter and access all the data in one central location.

The SMA Sunny Boy inverter, the most popular grid-tied photovoltaic inverter in Europe, is now UL 1741 Listed and available in North America. Sunny Boy’s exstensive track record in some of the world’s most demanding markets has made it a favorite among PV professionals everywhere. Over 250,000 Sunny Boy inverters have been installed worldwide. Superior design, rock-solid German engineering and exceptional real-world efficiency have made Sunny Boy the top choice for American solar designers.

Sunny Boy’s unsurpassed reliability and efficiency are the result of SMA’s manufacturing philosophy that combines simple design with robust execution. SMA’s state-of-the-art maximum power point tracking performance results in greater real-world energy capture than any other grid-tied inverter. Sunny Boy’s safety and reliability record is also exceptional due, in part, to the inverter’s redundant grid monitoring and built-in ground fault detection and interruption protection. The inverter’s IGBT power stage generates a nearly perfect sine wave with the lowest harmonic distortion in the industry and meets ultra-strict FCC EMC standards. SMA’s unique String Inverter technology makes future system expansion simple. SMA advanced communication options are available to satisfy almost any application
