The SMA Sunny Boy 2.5-VL-40 inverter sets a new benchmark for small photovoltaic (PV) systems. Not only is it light weight (9kg) and small in size, it also has a wide input voltage range from 80 to 600V and is compatible with most of the commercially available panels. Within this flexible exterior design holds some of the most advanced inverter technologies such as OptiTrack Global Peak and integrated webservers.
