KOSTAL Solar Electric
Implementation of the Kostal PV inverters.
PV-Inverter.Kostal
Tested on - Kostal Plenticore 5.5 - Kostal Pico 5.5
With versions: - UI Version: 01.18.05255 - MC version: 01.47 - IOC version: 01.45
Older versions had problems with the implementation of sunspec.
Configuration in Kostal UI: Modbus must be active and byte order must be big-endian for sunspec.
Implemented Natures: - ElectricityMeter - ManagedSymmetricPvInverter
PV-Inverter.Kostal.Piko
Implements the KOSTAL PIKO PV inverter using HTTP/HTML parsing.

Channels
The component provides the following channels:
Standard PV-Inverter Channels
-
ActivePower: Current AC power output [W] -
ActivePowerLimit: Active power limit (not used) -
MaxApparentPower: Maximum apparent power (not used)
KOSTAL PIKO Specific Channels
-
Status: Current inverter status (e.g., "Aus", "Feed-in", etc.) -
TotalYield: Total energy production [kWh] -
DayYield: Daily energy production [kWh]
DC String Channels
-
DcString1Voltage: DC voltage of string 1 [V] -
DcString1Current: DC current of string 1 [mA] -
DcString1Power: DC power of string 1 [W] -
DcString2Voltage: DC voltage of string 2 [V] -
DcString2Current: DC current of string 2 [mA] -
DcString2Power: DC power of string 2 [W] -
DcString3Voltage: DC voltage of string 3 [V] -
DcString3Current: DC current of string 3 [mA] -
DcString3Power: DC power of string 3 [W]
Implementation Details
This component:
-
Connects to the KOSTAL PIKO inverter via HTTP using Basic Authentication
-
Fetches the main status page HTML
-
Parses the HTML using Jsoup to extract values
-
Updates channels every 10 seconds
-
Handles connection errors gracefully
The HTML parsing is based on finding table cells with bgcolor="#FFFFFF" attribute and extracting values in a specific order.
Compatibility
This component is compatible with KOSTAL PIKO inverters that provide a web interface with Basic Authentication (typically username: pvserver, password: pvwr).
Tested with: * KOSTAL PIKO 10.1
