Flexible System Design

Always optimally supplied with solar power—today, tomorrow and in the future

A PV system and the corresponding storage system is as unique as its user’s power consumption and home.

Whether the family is growing, an electric car needs to be recharged, the garage is being turned into a workshop—up to three connectable high-voltage batteries supply loads even when the sun is not shining.

Neu installieren: Solaranlage mit Speicher

New installation: PV system with battery storage

A storage system makes you independent from conventional power companies and rising energy costs. Thanks to innovative technology, storage systems with the Sunny Boy Storage are particularly efficient and easy to install.

Modernisieren: Solaranlage mit Speicher

Modernise: PV system with battery storage

To use even more self-generated solar energy in the home, an existing PV system can be expanded into a fully fledged storage system with just a few additional components. The operator further reduces the amount of electricity purchased from the grid and minimises electricity costs.

Erweitern: Speicher-System an steigenden Bedarf anpassen

Expand: Align a storage system with increasing demand

Thanks to multistring technology, up to three high-voltage batteries can be connected to the Sunny Boy Storage anytime. This allows the storage system to be expanded gradually and adapted to individual needs.

SMA Smart Connected - How it Works


Activation of SMA Smart Connected

During registration of the system in Sunny Portal, you, as the installer, activate SMA Smart Connected and thus start automatic battery inverter monitoring by SMA.


Automatic battery inverter monitoring

SMA automatically checks the battery inverter for anomalies around-the-clock during operation. You and your customers benefit from SMA's many years of experience.


Proactive communication

After a fault has been diagnosed and analysed, SMA informs the installer and PV system operator immediately by email. Everyone is thus optimally prepared for the troubleshooting process ensuring minimum downtimes and reducing outlay and costs. The regular power reports also provide the installer with valuable information about the overall system.


Replacement service

If a replacement device is necessary, SMA automatically supplies a new battery inverter within one to three days of the fault diagnosis. As the installer, you can contact the PV system operator of your own accord and replace the device immediately.


Performance service

The PV system operator can claim compensation from SMA if the replacement device is not delivered within three days.

SMA Smart Connected is available in AU, AT, BE, CH, DE, ES, FR, IT, LU, NL, UK

Perfectly matched storage solution

In the SMA Residential Solution, the Sunny Boy Storage temporarily stores electricity from the PV system in a battery. Combined with the Sunny Home Manager 2.0, energy flows in the home can be managed intelligently and electricity costs further reduced. Solar power can thus be used 24 hours a day.
