HA Custom Component to integrate data from ABB/Power-One/FIMER PV mono-phase and three-phase inverters that support SunSpec Modbus (Sunspec M1, M103, M160), natively or through the VSNx00 wifi logger card. The VSNx00 provides a SunSpec to Aurora protocol adapter so that all modbus commands are translated to the proprietary Aurora protocol.
The component has been originally developed by @binsentsu for SolarEdge inverters, I adapted it, adding some features, rewriting all the registers’ mapping, for my Power-One Aurora PVI-10.0-OUTD 3-phase inverter to which I added a VSN300 card. It has also been tested with an ABB TRIO-8.5-TL-OUTD-S through a VSN300 and REACT2-3.6-TL through a VSN700 datalogger.
Register address map has been implemented following the vendor’s specification documentation listed here:
# Installation through HACS
Install it through HACS adding this as a custom repository: GitHub - alexdelprete/ha-abb-powerone-pvi-sunspec: HA Custom Component to integrate data from ABB/Power-One/FIMER PV Inverters that support SunSpec Modbus (Sunspec M1, M101, M103, M160), natively or through the VSN300 wifi logger card. then go to the integrations page in your configuration and click on new integration → ABB Power-One PVI SunSpec.
# Manual Installation
Copy contents of custom_components folder to your home-assistant config/custom_components folder. Restart Home Assistant, and then the integration can be added and configured through the native integration setup UI. If you don’t see it in the native integrations list, press ctrl-F5 to refresh the browser while you’re on that page and retry.
# Enabling Modbus TCP on the inverter
Enable Modbus TCP client on the VSN300, take note of the Unit ID (aka Slave ID) of the inverter (depends on the model, default on some models is 2 on others is 247) and during the configuration of the component, use the appropriate Slave address.
# Configuration Parameters Explained
custom name: name for the inverter, that will be used as prefix for sensors created by the component
ip/hostname: IP or hostname of the inverter
tcp port: tcp port of the datalogger
slave id: it’s the unit id of the inverter in the chain (you can have multiple inverters in one chain, default is 254 usually, but on some it’s 2)
register map base address: it’s the base address from where the register map starts, usually it’s 40000, but for VSN300 datalogger it’s 0
polling period: frequency, in seconds, to read the registers and update the sensors
If you like this integration, I’ll gladly accept some quality coffee, but please don’t feel obliged.
