Average power spikes

Questions
#1

In my daily graphs there is some kind of problem with the average value. I don’t see this for other people’s setups, so it must either be a data issue or a configuration issue.

For some reason it’s always a factor of 1200:

What am i doing wrong? i’ve looked in the help, but there it just states that it’s a calculated average value. Ok, I get that, but why is not calculated correctly then?

#2

Average power is calculated from energy.

The issue is the energy is increasing in 100Wh blocks rather than 1Wh, so it is not accurate enough.

#3

Ah indeed. Sadly my Growatt only sends 1 decimal after the kWh for the Total production. So 100Wh is the minimal increase per cycle. So the average won’t work correctly in my case then :frowning:

#4

The energy upload should be disabled by either not uploading it or sending -1 values. This will allow energy to be calculated from power.
