SMA Sunny Boy Storage 2.5

Simply Greater Independence
The Sunny Boy Storage is the battery inverter for high-voltage batteries from important reputable manufacturers. With a charge and discharge power of 2.5 kW, it is ideally suited to handle electricity demand of a private household.

More sun for the home
Storing solar energy simply and cost-effectively
The Sunny Boy Storage is the right solution for people who want to make their home independent from conventional electric utility companies and rising electricity costs by using intermediate storage for their solar energy. This gives you maximum flexibility both now and in the future

A smart combination
Flexible and cost-effective system design around the clock
With the Sunny Boy Storage, customers benefit from markedly reduced system and installation costs and flexible applications. Thanks to AC coupling, the battery inverter can be installed or expanded in any location, at any time, regardless of whether or not there is already a PV system installed. The Sunny Boy Storage is a true jack-of-all-trades, one that uses high-voltage technology to make it cost-efficient and light weight. It also uses just a few components, because the most important functions for intelligent battery management are already integrated. This makes the Sunny Boy Storage the ideal choice for putting more sun in your electricity supply.
