Energy dashboard - PV produces electricity at night

[RudiSH (Thorsten)]

Hello,
I currently have HA running very well and wanted to start integrating the Energy Dashboard.

First of all, data about my PV system:
Inverter 1: Huawei Sun2000-8KTL
Inverter 2: Huawei Sun2000-6KTL
Storage 15KW: Huawei Luna 2000 (connected to inverter 1)

The integration was done via HACS (Huawei Solar)

I have integrated various constellations of entities in the energy dashboard, unfortunately I got the right result, each time values were displayed that should not be there because it is dark. The system shows energy production at night.

The currently connected entity reads out the total yield per inverter.
The storage is connected to inverter 1, the values that should not be there come via inverter 1. Could this have something to do with the battery?
If so, what could it be? I can’t understand the problem

In this screenshot you can see 3 points (marked with the red pen) that go from PV to grid, home and battery.
It is currently 9.40 pm and dark. How is this supposed to work?
Does anyone have an idea where the problem is?
Thank you.

I have just stood in front of my electricity meter and observed it.
In the 2nd line, where I can see what my current consumption or feed-in is, it goes really round in the dark, among other things there are also minus values, which in HA are probably then evaluated as production of the PV system.
This is also displayed in the graphs.

Now I just have to find out which entity I can use for the display without this display appearing at night.

I would be grateful for any tips.

I used some ChatGPT and found the solution. At least I think so at the moment.
I will use a new sensor to add the values determined for both inverters and then check whether the value < 0 then take 0 otherwise. Let’s see what the values look like tomorrow when it’s sunny, at least the error is no longer occurring at night. The sensor currently looks like this, it is in my tamplates.yaml

- sensor:
    - name: "PV-Erzeugung Gesamt (kWh, korrigiert)"
      unique_id: pv_erzeugung_gesamt_kwh_korrigiert
      unit_of_measurement: "kWh"
      state_class: total_increasing
      device_class: energy
      state: >
        {% set wert1 = states('sensor.wechselrichter_gesamtenergieertrag') | float(0) %}
        {% set wert2 = states('sensor.wechselrichter_gesamtenergieertrag_2') | float(0) %}
        {% set gesamt = wert1 + wert2 %}
        {{ gesamt if gesamt > 0 else 0 }}

It seems that you set the total inverter output as the solar production, which includes the battery output. From the images from github you should take “Total yield” as PV generators, “total charge/discharge” as the battery config and “Consumption”/“Exported” as the grid config. The config is also described here: huawei_solar/images/energy-config.png at 979f49c11b03e9d5609dabbfaa8711ae722c1d45 · wlcrs/huawei_solar · GitHub

Deutsch: Vermutlich hast du den gesamten Inverter Ausgang als PV konfiguriert, dieser gibt aber auch den Strom aus der Batterie ab. Du solltest die Einstellungen so setzen wie in dem Screenshot oben.
