Intelligently optimize solar yields
Proven product features and integrated software solutions ensure yield optimization over the entire service life of the system. Even with shading. The patented SMA ShadeFix inverter software optimizes the solar yield in almost any situation. Additional security is provided by the SMA Smart Connected inverter monitoring system, which detects faults at an early stage and automatically reports them to the installer.
- Integrated software for yield optimization SMA ShadeFix
- Dynamic active power limitation: direct use of surplus energy, less grid consumption
- Automatic device monitoring via SMA Smart Connected
- System visualization via Sunny Portal
- Local visualization via Smart Inverter Screen

SMA Smart Connected
Investment security included
With SMA Smart Connected, SMA is the first manufacturer to offer free, automatic monitoring of the inverter, which enables the installer to provide fast and precise service to the customer. In the event of an inverter fault, we provide the diagnosis immediately - the installer can rectify the fault quickly, saving valuable working time and analysis costs. If the inverter needs to be replaced, SMA will send a replacement device free of charge within a very short time.

SMA Smart Connected
How it works
Activating SMA Smart Connected
When registering 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 around the clock for anomalies during operation. You and your customers benefit from SMA's many years of experience.
Proactive communication
After diagnosing and analyzing a fault, SMA immediately informs the installer and system operator by e-mail. All parties are thus optimally prepared for troubleshooting. This minimizes downtimes and reduces effort and costs. The installer also gains valuable insights into the overall system from the regular performance reports.
Replacement service
If a replacement device is required, SMA will automatically deliver a new inverter within 1 to 3 days of fault diagnosis. As the installer, you can actively approach the system operator and replace the inverter immediately.
