My downloadable 15 minute data from the SolarEdge monitoring site give two columns of data. The first is System Production and the second Solar Production. Do you receive both columns and how does PVOutput handle the data you receive?
The totalActivePower column is used to record generation data.
The two columns are labeled “System Production” and “Solar Production” respectively.
Anecdotally, it is clearly (and incorrectly) using the system production numbers rather than the solar production numbers. It reports that our system is “producing” in the middle of the night while the inverter is producing power from the battery.
(And sorry for resurrecting such an old thread… I misread “Oct '17” as just “Oct 17” and thought it was only a couple of months old.)
