Home Assistant

Kostal Plenticore Solar Inverter

The Kostal Plenticore integration allows you to get data from Kostal Plenticore solar inverters and integrate them into your Home Assistant installation. It allows you also to change some of settings values of the inverter.

The integration uses the REST-API interface which is also used by the integrated Web-UI and therefore uses the same password.

Configuration

To add the Kostal Plenticore Solar Inverter integration to your Home Assistant instance, use this My button:

Sensors

The integration disables most of the sensors per default. You can enable it in the Entity page. The sensors are split into two sets, one for the process data and one for the setting values.

The Plenticore inverter provides much more data endpoints, some of them are also dependent of the version of the firmware. If you are missing process data values, open an issue with the necessary information or make an pull request.

Common template sensors

Energy to grid total
template:
  - sensor:
    - name: "Plenticore Energy PV to Grid Total (Template)"
      unit_of_measurement: "kWh"
      device_class: energy
      state_class: total
      state: >
        {% set yield = states('sensor.scb_energy_yield_total') | float %}
        {% set batteryToHome = states('sensor.scb_home_consumption_from_battery_total') | float %}
        {% set pvToHome = states('sensor.scb_home_consumption_from_pv_total') | float %}
        {{ yield - pvToHome - batteryToHome }}

The sensor.scb_energy_yield_total entity contains the total energy. This includes both the energy delivered to the home as well as the energy from the battery to the home. Think of it like all energy that leaves the inverter on the AC side. Hence, to calculate the amount of energy flowing into the grid, you have to subtract the energy from the battery and PV to the home.

Settings Sensors

The following sensors are available in the library:

Name Unit RW Description
Battery Dynamic SoC RW Dynamic SoC.
Battery Smart Control RW Enable smart battery control
Battery Strategy RW Battery strategy.
Shadow Management RW PV string shadow management.
Setting values change less often, therefore these sensors are only polled every 5 minutes.

Battery Strategy

This sensor is on by default, which maps to the “Automatically” mode in the Kostal Plenticore Plus documentation. This mode is recommended for regions with little snowfall.

Turning this sensor off maps to the “Automatically economical” mode. Consequently, the inverter controls the battery charging automatically but switches the battery off when there is insufficient PV energy to charge the battery for longer periods. This mode is recommended for regions with a lot of snowfall.

Battery Smart Control

The Battery Smart Control sensor appears as a select field labeled “Battery Charging / Usage Mode” with three options:

  • None: the battery is loaded immediately when there is PV energy spare.
  • Battery:SmartBatteryControl:Enable: the battery loading optimizes grid feed-in and battery loading. This setting is recommended when the grid feed-in is limited to, for example, 70% of the Plenticore Plus peak power.
  • Battery:TimeControl:Enable: battery charging/discharging can be configured flexibly at different times (tariff periods). Detailed settings must be done on the web frontend of the Kostal Plenticore Plus inverter. This option activates the time-controlled battery usage mode.

Number

The following Number entities are available. The values could also be change from Home Assistant.

Name Unit RW Description
Battery min Home Consumption W RW Min. home consumption power for battery.
Battery min SoC % RW Min. SoC of battery.
