SMA Sunny Boy 240-US*, 240 Watt Micro inverter *MUST BE PURCHASED WITH THE SMA MULTIGATE-US
SMA's Sunny Boy micro inverter system enhances design flexibility for installers in the U.S. and across the globe. It features simple installation, an innovative communications platform and superior reliability, and is especially applicable for residential systems and systems with complex shadowing situations.
Among the Sunny Boy micro inverter system's ground-breaking innovations is its ability to monitor via the Sunny Portal with the existing Sunny Boy inverter line, making string/micro hybrid installations a reality. Hybrid installations have the potential to minimize installation costs while maximizing energy harvest.
