About The Project

Access ModBus data from almost any network connected Sungow Inverter.

On first connection the tool will query your inverter, retreive the model and return the correct registers for your device. No more searching registers or creating model files.

Register information based on official documentation: Communication Protocol of PV Grid-Connected String Inverters and Communication Protocol of Residential Hybrid Inverters

Has muliple export locations out of the box:

• Console - Log directly to screen
• MQQT - Load into MQTT, and optionally Home Assistance Discovery
• PVOutput - Load into PVOutput.org
• and more coming....

Usage

See config-exmaple.py it contains default options and comments.

If you want to use the new Energy section in Home Assistant, add the following sensors to convert from Power to Energy:

sensor:
  - platform: integration
    source: sensor.inverter_active_power
  - platform: integration
    source: sensor.inverter_export_to_grid
  - platform: integration
    source: sensor.inverter_import_from_grid
