SMA Sunny Boy SB1200 Grid Tie inverter

 

Proven technology for secure investments

Universally applicable: the Sunny Boy inverters 1200, 1700, 2500 and 3000 are used in the most diverse AC grids thanks to their galvanic isolation. In addition, the devices are suitable for simple grounding of the generator. Their integrated ESS DC switch-disconnector makes installation simpler while also reducing assembly costs. Equipped with the OptiTrac MPP-tracking process, it will always find the best working point, even under dynamic weather conditions. In this way, it reliably converts solar energy into solar yield.
