Deye Solar Inverter Zero Feed-In (Nulleinspeisung)

Hi everyone,

For those guys who are looking for a working solution to give the Deye Microinverter e.g. 600W or 800W a zero feed-in, I would like to share my template & automation here:

  1. What do you need?
  • Deye Microinverter
  • Solarman integration in Home Assistant
  • Energymeter e.g. Shelly pm between Inverter & Grid
  • Shelly Integration in Home Assistant
  • Energymeter on your Grid e.g. Esp32 with Tasmota and IR Read Dongle to get the Current consumption in Watt from the Grid in realtime.
  1. Make a custom template “Nulleinspeisung” (zero feed-in) under devices & services → helper:
{# set your max Power of your Inverter in Watt: #}
{% set maxInverterPower = 800 %}
{# set your max Inverter Regulation e.g. 100 or max 120 in percent: #}
{% set maxInverterRegulation = 100 %}
{# If your Inverter is making an offset, you can change it here in Watt: #}
{% set inverterPowerOffset = 0 %}
{# Set here your min amount of your base load in your house in Watt: #}
{% set minSolarLimit = 100 %}
{# Here can you change the Zero Point goal e.g. -5, o or +10 in Watt: #}
{% set zeroPointGridAdj = -5 %}

{% set newSolarLimit = 0 %}
{% set newRegulationLimit = 0 %}

{# Put in your current Grid sensor in Watt: #}
{% set curGridUsage = states('sensor.tasmota_stromzahler_strom_power_curr') | float * -1 | replace('W','') | int %}
{#Put in your current Solarpower sensor in Watt e.g. a shelly 2pm (the inverter sensor is too lazy): #}
{% set curSolarProd = states('sensor.solaranlage_solar_leistung_power') | float (0) | replace('W','') | int %}

{% set newSolarLimit = (curSolarProd - (curGridUsage + zeroPointGridAdj)) %}

{% if newSolarLimit <= minSolarLimit %}
  {% set newSolarLimit = minSolarLimit %}
    {% elif newSolarLimit >= maxInverterPower %}
       {% set newSolarLimit = maxInverterPower %}
{% endif %}

{% set newRegulationLimit = ((newSolarLimit * maxInverterRegulation) / (maxInverterPower - inverterPowerOffset)) %}

{{ newRegulationLimit | round (0) }}
  1. Make an automation “Nulleinspeisung” (zero feed-in) under config → automations & scenes:
alias: Solar Nulleinspeisung
description: ""
trigger:
  - platform: state
    entity_id:
      - sensor.solaranlage_solar_leistung_power
    to: null
    from: null
    enabled: true
condition:
  - condition: state
    entity_id: sensor.solarman_on_off_enable
    state: "ON"
action:
  - service: solarman.write_multiple_holding_registers
    metadata: {}
    data:
      register: 40
      values: "{{ states('sensor.kalkulation_nulleinspeisung') | replace('%','') }}"
  - delay:
      hours: 0
      minutes: 0
      seconds: 10
      milliseconds: 0
mode: single
  1. Enjoy to see the Gauge Display between -5 & 5 Watts :grin::+1:

With kind regards

Hallo Mathias,
das klingt interessant.

Helper konnte ich anlegen.
Aber wie lege ich die Szene an?
Wo muss ich deinen Code reinkopieren?

Du musst den Code direct in die automations.yaml eintragen.

Den Sensor musst du auch mit kalkulation_nulleinspeisung anlegen, sonst gibts auch nen Fehler.

Ich habe es fĂĽr mich umgeschrieben, und es funktioniert.

Hi zusammen,
kann das jemand etwas genauer erklären bzw. bekommt man da etwas zu sehen bzw. wie
Danke!

Hallo zusammen

ich habe das Skript implementiert und es funktioniert wunderbar. Musste aber ein paar Anpassungen fĂĽr meinen Deye 600W Inverter vornehmen:

fĂĽr die Automation:

alias: Solar Nulleinspeisung
description: ""
trigger:
  - platform: state
    entity_id:
      - sensor.solarman_status_lastupdate
    to: null
    from: null
    enabled: true
condition:
  - condition: state
    entity_id: sensor.solarman_status_connection
    state: Connected
    enabled: true
action:
  - metadata: {}
    data:
      register: 40
      values: "{{ states('sensor.kalkulation_nulleinspeisung') | replace('%','') }}"
    action: solarman.write_multiple_holding_registers
  - delay:
      hours: 0
      minutes: 0
      seconds: 10
      milliseconds: 0
mode: single

der Helper wird folgendermaĂźen eingetragen: Helper-> Create helper->Template->Template sensor, wobei der Code bei State template eingetragen wird (geht mit copy-paste) und hier bei Template options angepasst werden kann:

hey there, since there is a new HACS integration of Solarman and the “writing action” in the scripts above my posts is depricated, here is my acually version of the automation script which use the new Deye-Sensors:
Its now very easy to handle. Have fun

alias: Solar Nulleinspeisung
description: ""
triggers:
  - entity_id:
      - sensor.solar_power
    to: null
    from: null
    enabled: true
    trigger: state
conditions:
  - condition: state
    entity_id: binary_sensor.deye_connection
    state: "on"
    enabled: true
actions:
  - action: number.set_value
    metadata: {}
    data:
      value: "{{ states('sensor.nulleinspeisung')}}"
    target:
      entity_id: number.deye_active_power_regulation
  - delay:
      hours: 0
      minutes: 0
      seconds: 10
      milliseconds: 0

Hallo, erst mal danke fĂĽr die Beschreibung des Templates.

Weiss jemand ob man den Wert “Solarman Active Power Regulations” beliebig oft im Deye ändern kann? Bei z.B. einem Wechselrichter von APsystems EZ1-M wird der Werte in einen Flash Speicher geschrieben wird der nur eine begrenzte Zahl von Schreibzyklen hat.

TIA JĂĽrgen
