Did you install solar panels on your house?
And are they connected to an inverter build by SMA?
If so, you can use this app to monitor your PV installation!
See how much energy it generated today, this month and this year.
Your SMA inverter needs to be connected to SMA's Sunny Portal, using e.g. an SMA WebConnect or WebBox device.
And you need an account for the Sunny Portal website.
Don't have any of the above, but still interested?
Use the "demo data" button and try the app!
