Sunny Boy 2.5 (SB2.5-1VL-40)


SMA Sunny Boy 2.5


Sunny Boy 2.5

The completely redesigned Sunny Boy 2.5 is the perfect inverter for customers who want to take full advantage of their small PV system. Among other features, it enables an increase in consumption of self-generated power, allows versatile uses, and is very easy to integrate into the home network. In addition, its innovative design and new communication concept offer many advantages during installation and commissioning. Thanks to direct communication with the SMA Energy Meter, both limitation to 70 percent, which is required in Germany, and limitation to 0 percent is possible.
