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.
