Data incorrect

Hi All

Never really looked too deeply into PVoutput since setting it up years ago. Thought I’d check it today and I ma noticing the data does not seem to be correct.

Yesterday its saying I generated 25kw when the fronius app says 27kw

Seems each day there is a 2kwh difference.

My antique TED5000 software system reports slightly different as well. I correct my numbers to the reported numbers on my electric company’s meters so that I can get a very accurate number that is close to my end of month production/usage. My TED5000 software has the capability to adjust the relative readings of the CTs and I adjust them to match the electric company’s meters. (in 0.1% increments/reductions up to 5%). Alternatively, you can apply rules to your PV output numbers that can automatically adjust them in real time.
