Solis Modbus Integration for Home Assistant
Description
The Solis Modbus Integration for Home Assistant is a streamlined solution to connect your Solis inverter with Home Assistant. This integration was inspired by fboundy’s ha_solis_modbus. However, it enhances the native Modbus integration in Home Assistant by consolidating multiple register queries into single calls, eliminating unnecessary overhead.

Solis cloud
You will lose access, unless you use a waveshare device. You will still have the option to disable the modbus, when updates are required. https://github.com/Pho3niX90/solis_modbus/discussions/154
Installation
To install the Solis Modbus Integration, follow these steps:
Open your Home Assistant instance.
Navigate to the “HACS”.
Click the 3 dots menu
Click on “Custom Repositories”
Fill in the repository “https://github.com/Pho3niX90/solis_modbus”, and category “Integration”
Now search for “Solis Modbus”
Click on Download
Total Sensors
Whilst the solis inverters do provide total sensors for today, yesterday, month and year. I highly suggest to create a utility meter in HA, as a time difference between HA and Solis might have the values reset before midnight, causing issues in charts.
Manual Installation
Copy the “solis_modbus” folder into your “custom_components” folder
Setup
Navigate to Settings -> Devices & Services
Click on “+ Add Integration”
Search for “Solis Modbus”
Add in the IP of your inverter in the first box, and port in the second.
Connection Type: S2 is the default option, only select waveshare if you are using a waveshare device, and some sensors are higher than normal, see here https://solis-modbus.readthedocs.io/en/latest/sensors.html#waveshare
