Simply greater independence
Sunny Boy Storage 2.5
Storing solar energy simply and cost-effectively
More sun for the home
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.
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.
Approved batteries and information on battery communication connection
Flexible and cost-effective system design around the clock
A smart combination
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.
Flexible
For new and existing systems: reduced installation costs, can be retrofitted and expanded at any time, as needed
For almost all PV system types: string inverters, module inverters and power optimizers
Can be combined with numerous types of energy: PV, wind energy, combined heat and power plants
Choice of lithium-ion battery (for example, from our partners LG or BYD)
Efficient
Most cost-effective AC-connected battery inverter on the market
97 % efficiency allows for optimal use of cached energy
Maximum PV yields while meeting all applicable regulations for feed-in limits (e.g., EEG, KfW 275, Zero Export)
Easy to use
Quick and straightforward one-person installation, thanks in part to it weighing only 9 kg
Simple installation using a smartphone or tablet via WLAN and an intuitive web interface
Everything at your fingertips thanks to its direct connection to Sunny Portal
The right solution, now and in the future
Keep up with everything
Systems with the Sunny Boy Storage can be flexibly adapted to individual needs at any time. Whether the family situation changes, perhaps with the purchase of an electric car, which needs charging daily, or with a swimming pool in the garden for pleasure–with the Sunny Boy Storage, storage systems and PV systems can always be designed or expanded to suit specific requirements. The battery inverter is also versatile when it comes to the method of generating energy. From the photovoltaic system and the wind turbine system to the combined heat and power plant, anything is possible.For a secure electricity supply at any time.
New installation: PV system with battery storage
Would you like to be independent from conventional power generators and rising energy costs? The Sunny Boy Storage is a great, cost-effective solution. You can install a storage system with the lowest-possible costs and just a few components. You can start storing the energy from the sun—quickly and simply.
Modernize: PV system with battery storage
Are you still feeding valuable energy into the grid with your PV system, even after the feed in-tariff has expired? Then simply use a storage system to be able to use the energy you produce yourself. You’ll benefit from reduced energy purchases and enjoy greater independence from your electric utility company. You only need three additional components: With the Sunny Boy Storage, the battery and the Energy Meter, you can turn your existing PV system into a full-fledged storage system.*
* For PV inverters without Speedwire / Webconnect, it makes sense to integrate the Sunny Home Manager 2.0 into the system.
Expand: Align an existing PV storage system with increasing demand
Would you like to expand your existing system to handle additional loads with solar energy? Not a problem for systems with the Sunny Boy Storage. You can expand your PV system retroactively at any time to meet your energy needs, independent from the storage system.*
* For PV inverters without Speedwire / Webconnect, it makes sense to integrate the Sunny Home Manager 2.0 into the system.
