Sunny Boy 3300/3800

One of the most important criteria when purchasing an inverter is its efficiency. SMA has set a new record for transformer-based devices at 95.6%.The higher the efficiency, the lower the losses that are incurred when converting direct current produced by the solar modules into alternating current. As well as ensuring the effectiveness of the OptiCool active cooling system, an all new, extra robust aluminium die-cast enclosure with a dual-chamber design also safely protects the electronic components from wind and weather.
