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.

Flexibly expandable anytime

With the Sunny Boy, PV system operators can ensure that their PV system always generates maximum yields. If greater use of solar power is made in your own home, intelligent energy management and SMA storage solutions can be added at any time to systems with the Sunny Boy.

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.

Performance Service

SMA compensates PV system owners if the replacement inverter cannot be delivered within three days.

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