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

Flexible System Design

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 all loads even when the sun is not shining.

New installation: PV system with battery storage

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

Modernize: 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 minimizes electricity costs.

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

Investment security included

With SMA Smart Connected, SMA offers free and automatic inverter monitoring that helps installers to provide customers with a quick, targeted service. If an inverter fails, SMA proactively informs the PV system owner and the installer. In this way, PV system owners and installers benefit from minimized diagnosis and downtime. If it is necessary to replace the inverter, SMA sends a replacement device fast and free of charge.

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 inverter monitoring by SMA.

Automatic inverter monitoring

SMA automatically checks the 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 analyzed, 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 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 inverter immediately.

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.
