SMA Sunny Boy 3300 Inverter with ESS Switch

The Best in their Class

One of the most important criteria when purchasing an inverter is its efficiency. The higher the efficiency, the lower the losses that are incurred when converting direct current produced by the solar modules into alternating current.

SMA has set a new record for transformer-based devices of this power class by achieving a maximum efficiency of up to 95.6 %.

As well as ensuring maximum effectiveness of the OptiCool active cooling system developed by SMA, an all-new, extra robust aluminum diecast housing with a dual chamber design also safely protects the electronic components from wind and weather.
