This looks good. At least the data is now different.
If this works, you should delete the items that are marked as deprecated.
Today the Watt values are both zero, whyever …
After restarting the browser, and lateron the whole PC,
I have the “black screen” syndrome, in the browser now.
Will have a look at it this evening. Probably a browser issue …
The values on the right, shown in this screenshot, are not okay:
For example, the 3 kW Inverter: it is not 9 thousand and 243 kWh,
it is 9 comma 243 kWh.
But probably this is simply the different usage
of the char “decimal point” and “comma” in english and german language ?
Would be enough to show one digit behind the comma
( in case the openHAB system allows formatting the values shown here … )
This shouldn’t have been any different to the original binding, so either it’s a bug (i.e. separate issue), or a display / formatting issue.
Could you please post the items code for them?
Please also try reverting to the original binding (delete/move the custom jar from the addons folder and reinstall the official binding) and see whether the Day Energy is different. Also With the original binding, see if Inverter1Power shows any value.
I’m not jet at home … this screenshot shows the old POWER, with valid value of 865 Watt
(screenshot copied from my post #4 in this thread)
I think I also have screenshots from the official binding on my PC at home,
so probably I don’t have to reinstall the official binding for the display / formatting issue.
Okay … it was said I should remove the .jar file from folder addons, after installation.
I did it, yesterday, and when I came home today, I found this:
So the system was unable to work … 
So now - the display / formatting issue. This screenshot was made with the original Fronius binding:
I can only compare this to the values stored in my sonnen battery, from that day:
- Fronius 1+2: 6,902 + 19,377 = 26,279 kWh
- sonnen says: 30,3 kWh
Might be measurement differences between Fronius Inverters and sonnen battery,
but goes in the same direction. So something between 26,279 kWh and 30,3 kWh might be the truth … 
Please note the “0,00 W” This is much too high precision.
“0 W” would be fully enough, as the displayed value.
So the inverter power works fine.
The day energy and display formatting is not a binding issue. Please check your display formatting setting. See https://www.openhab.org/docs/configuration/items.html#state-presentation

Here are the steps:
- Edit your Item for Day Energy
- Add Metadata called
State Description - In the formatting, type in
%.0f kWhthen click Save. This will give you the energy in kWh without any decimal points.

I’m doing the first steps in openHAB, so I really don’t know these basic things.
I will follow Your steps and edit my Items. Thanks for Your help !
Will Your changes be merged into the official Fronius binding one day ?
If you can confirm that it works the way you expected it to, then I’ll mark my changes ready to be reviewed.
I will keep an eye on it over the weekend, and then confirm.
Hm … I did not find “formatting”.
Instead I found “Step = Minimum interval between values”
But it works as expected … (openHAB 4.0.1)
Looks good now, values are reliable:
This is from FRONIUS website (same time, but website is not Reatime, results in differences):

I can confirm that it works, and You can mark the changes ready to for review !
Thanks, I’ve already marked it ready for review earlier.

Probably there is a naming convention for INVERTER parameters, inside the openHAB project ?
I just found Item “AC Power” which delivers the same value as “Inverter Power”.
