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 - SMA Smart Connected

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.

Replacement Service - SMA Smart Connected

Replacement Service

If a replacement device is necessary, SMA automatically supplies a new inverter. 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.
