Quick question, for those who have a SMA solar inverter and use the related Sunny Portal to monitor and export the data from your system, does the web portal cost anything to use?
I have also heard there is a professional version of the Sunny portal, does that cost anything?
Side question: How long is the data retained for?
Regards: Elliott.
