My understanding is that the average and the normalised data is based off the power data. Is this always in multiples of 1200w?
Cheers,

no over 5 min outputs average regardless of output unless, output --0
So does this looks right?
In my mind if it’s taking an average between 3522w and 2347w then it should show the average as 2935w but is instead showing 2400w?
hi the average is always 5 min behind real power and so is averaged, the power is taken at A instant time every 5 min only this is why on the chart the average is sometimes higher then the power output.
there seem to be somthing wrong with your average power readings. mine looks like this
Thanks @jimdcollie.
I can see from my graph what it’s trying to do but with my data it doesn’t seem to be doing it right! The average seems to be jumping around with the actual value being the smoothed version of the average!!
Not sure why as the data I’m passing it is all accurate, I’m uploading it every 5 minutes so very strange!
The ‘average power’ is calculated based on the energy reported.
hi possibly its this. go to settings then edit system at bottom right, scroll down to Advanced setings, net delay should be set to NONE {not 5 min,} hope this fixes it jim
No luck unfortunately. I think it may be due to the resolution of my energy data from my inverter which is out of my control.
At 1240hrs it had generated 12.600kWh of electricity. At 1245 it had generated 13.000kWh.
- Energy difference: 13.0 kWh - 12.6 kWh = 0.4 kWh.
- Time interval: 5 minutes = 0.08333 hours.
- Average power: Power = Energy / Time = 0.4 kWh / 0.08333 hours ≈ 4.8 kW.
This matches up with the average in PVOutput.
Seems like unless a firmware update changes my modbus data resolution that my averages will be inaccurate.
I think mine works like this, average power from 12,35 is used for the calibration of the 12.40 average power, average power is always 5 min behind live power, to check this see you PVO on inverter start up, there is NO average power showing for the first 5 min of the day, is your FOX ESS inverter sending dater every 5 min and how have you configured it to PVO ? Jim
have just looked at your system and all your readings are odd, ie power is not changing unless there is a big input of PV power, this should always change if more than 10 whatt produced over 5 min, also you average power is only showing some 5 min NOT every 5 min interval, perhaps if you like you can send me a screen shot of your PVO settings {blank out passwords and Keys} and i will see what settings are different to mine, only if you want to share OK jim
