SMA Smart Connected - Premium monitoring service for reliable system performance

Due to the current situation around COVID-19 our SMA Service response times may be longer than usual.

With the free use of "SMA SMART CONNECTED," you can still ensure that the error events of your SMA inverters will be sent directly to the SMA Contact Center or to the installer. SMA has decided to extend the activation period of SMA SMART CONNECTED to two years after commissioning giving you the opportunity to use SMA SMART CONNECTED for this period.

All you have to do is activate SMA SMART CONNECTED in your Sunny Portal. Instructions for activation can be found here:

  • Average, daily nominal PV system power: 18 kWh
  • Self-consumption rate: 30% (5.4 kWh/day)
  • Electricity rate for purchased electricity: €0.295/kWh
  • Feed-in tariff: €0.118/kWh (as of October 2018)
  • Detecting increased electricity costs: 30 days

* The inverter will not start up due to a disturbance on the first day of the billing period. The increased electricity bill alerts the PV system owner to the disturbance only after 30 days.
** The installer must drive to the PV system to identify the cause of the disturbance. The PV system can be repaired only during the second visit with the replacement device procured in the meantime.

The example shown here is for illustrative purposes only and it is based on the assumptions outlined. Changes to these assumptions would change the projected outcome.
