With SMA Smart Connected, SMA offers free, automatic inunlar monitoring that allows the installer to provide fast, targeted services to its customer. SMA proactively informs the installation owner or installer of any inunr malfunction. This reduces diagnostic and downtime times to a minimum, to the benefit of facility operators and installers. If a replacement is necessary, SMA will ship the exchange inser free of charge and as soon as possible.




SMA Smart Connected Activation

As an installer, you activate SMA Smart Connected when recording the installation on Sunny Portal and you start automatic monitoring of inverters by SMA.



Automatic inverter monitoring

SMA performs an automatic and permanent check of the inunntor to detect malfunctions. This allows you and your client to benefit from SMA's long-standing experience.



Proactive communication

After diagnosing and analyzing an error, SMA immediately notifies the installer and the final customer via email. All parties are thus prepared for correcting errors, minimizing downtime and saving time and money. In addition, regular performance reports provide valuable information about the entire system.



Replacement service

If a device needs to be replaced, SMA automatically delivers a new inletor within 1 to 3 days after the error diagnosis. As an installer, you can anticipate the owner's request and replace the inputer.



Service performance

If the replacement inunr cannot be delivered within 3 working days, the owner of the facility is entitled to seek financial compensation from SMA.
