Whatever the starting situation


 New installation: photovoltaic installation with storage system

New installation: photovoltaic installation with storage system

Do you want to be no longer dependent on traditional electricity suppliers and ever-increasing energy costs? With Sunny Boy Storage, this is perfectly achievable at a lower cost. With very few components, a storage system is easy to install. So you can store solar energy quickly and easily.

Modernize: photovoltaic installation with storage systemModernize: photovoltaic installation with storage system

Do you continue to inject precious energy into the grid via your photovoltaic installation even after the injection fee? If this is the case, use this self-generated energy yourself with a storage solution. This reduces your levy on the public electricity grid and increases your independence from your electricity supplier. To do this, you only need three additional components: thanks to Sunny Boy Storage, battery and Energy Meter, your existing photovoltaic installation becomes a complete storage system.


Expand: adapt an existing photovoltaic energy storage system to growing needs

Expand: adapt an existing photovoltaic energy storage system to growing needs

Want to expand your existing facility to power additional solar energy? It's possible with Sunny Boy Storage! Any extension of the system after the fact is possible, just as you can adjust the photovoltaic installation to your individual needs at any time, regardless of the storage system.

For photovoltaic inverters without Speedwire/Webconnect, it is also relevant to integrate Sunny Home Manager 2.0 into the system.
