Erroneous usage data being logged to pvoutput

[gyrex]

Hi guys,

I’ve got a strange situation where erroneous data is being logged by pvoutput. I’ve got a large 60kWh battery connected to Victron inverters which effectively means my energy usage sits at or around 0kWh outside of PV feed-in.

I’m a donator and I’ve got a Fronius smart meter installed at the feed-in point and I’ve got Fronius log uploads enabled.

All the data from Fronius and my inverters show that there’s virtually 0kWh being used but for some reason every day at around 10:50pm-midnight, pvoutput shows a constant 1kWh being used which isn’t logged anywhere else other than pvoutput. Magically at midnight, the usage goes back to 0kWh. This happens every single day at the same time.

I’ve attached graphs and other data from Fronius Solarweb history and my utility provider which backs up this strange anomaly and it appears that the only erroneous part is pvoutput.

Any ideas on why this might be happening?

If you’re using the “auto=1” push option try removing it to see if makes any difference.

This option relies on “EnergyReal_WAC_Plus_Absolute” and “EnergyReal_WAC_Minus_Absolute” which isn’t always known to be reliable.

Thanks for responding mate. These are my pushes:

Inverter: /service/r2/froniuspost.jsp?sid=xxx&key=xxx

Fronius Meter: /service/r2/froniuspost.jsp?sid=xxx&key=xxx&auto=1&v6=Voltage_AC_Phase_1&v7=Voltage_AC_Phase_2&v8=Voltage_AC_Phase_3

LogData: /service/r2/froniuspost.jsp?sid=xxx&key=xxx&v9=Current_DC_String_1&v10=Current_DC_String_2&v11=Voltage_DC_String_1&v12=Voltage_DC_String_2

I can see there’s an auto=1 in the meter push but I thought this would be overridden by the log data?

I’ll remove it anyway and report back.

Now it’s reporting a constant 1kW load which is incorrect.

@gyrex

but I thought this would be overridden by the log data?

Suspect that the 5-minute meter pushes are generally incorrect and that the hour log pushes overwrites this with correct data.

The issue could be that the last log push midnight isn’t made, will need to wait till tomorrow to confirm, but vaguely do recall that this was a log push limitation when the feature was initially added.

Thanks for following up on this mate. This strange issue occurs at 10:50pm every day, shouldn’t the data between 10:50pm-11pm be overridden by the 11pm log data upload?
