Battery consumption peaks of 50 kW

Suddenly a number of battery consumption peaks of 50 kW.

This is completely impossible. Who knows how this can happen.

My battery is only 32 kW

Please detail your system.
Its a known issue with some third party devices and mods.

Hi,

“EnergyFromBattery” is basically the last flow, that is mathematically concluded. It kinda is “consumption/AC-need recorded, that is not seen as sourced from grid, neither from solar”.

That means, your issue is most likely that one of the other 3 figures jumped by that 50kWh.

  • Consumption you would have mentioned.
  • Solar does not produce “negative” values, thus there it would be energy2battery, if that counter bounces.

That leaves us with the grid value. Precisely with the /Ac/EnergyReversed Counter of your meter:

It’s regular value seems to be 50 kWh. And whenever that value turns to 0, the system assumes a counter reset - and as soon as the 50kWh are restored, the system concludes 50kWh feedin to just happened.

And that in above maths means: “That energy mathematically musst have come from battery”.

→ Find the issue, why your grid meter resets it’s EnergyReversed Counter to 0 occassionally and fix that :slightly_smiling_face:. It may be a meter issue, but also 3rd party implementation bug or therefore just carelessness on handling readfailurs / disconnects.

If you used a virtual grid meter in node red, make sure you don’t initialize it with defaults, as that will produce a 0 upon every reconnect / reboot / flow deployment.

To verify this is what’s happening, you can visualize that counter in VRM advanced. You may not see clean 0 due to averaging, but if you see spikes down in a otherwise forever incremental graph, that’s your issue.
