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
• MQTT - Load into MQTT, and optionally Home Assistance Discovery
• PVOutput - Load into PVOutput.org
• and more coming....

I have borrowed HEAVILY from the following projects, THANK YOU

• solariot
• modbus4mqtt
• ModbusTCP2MQTT

Getting Started

Local

git clone https://github.com/bohdan-s/SunGather.git
cd SunGather
pip3 install --upgrade -r requirements.txt

Copy config-example.py to config.py, change values as required (see comments in file)

copy config-example.py config.py

Run SunGather:

python3 sungather.py

Docker

docker pull bohdans/sungather
docker run -v {path to}/config.yaml:/config/config.yaml -e TZ=Australia/Sydney --name sungather bohdans/sungather

Note: replace Australia/Sydney with relevent timezone

Usage

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

If you want to use the new Energy section in Home Assistant, follow the Home Assitant setup below.

Home Assistant setup

In the SunGather config.yaml you need to set the smart_meter if you have one;

smart_meter: True

HA sensors created by the MQTT auto-discovery;

sensor.inverter_active_power
sensor.inverter_daily_generation
sensor.inverter_export_to_grid
sensor.inverter_import_from_grid
sensor.inverter_load_power
sensor.inverter_meter_power

Put the following into your sensors.yaml

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

The additional sensors then setup in HA are the following with Wh unit of measurement for the Energy platform.

sensor.sensor_inverter_active_power_integral
sensor.sensor_inverter_export_to_grid_integral
sensor.sensor_inverter_import_from_grid_integral

You need to utilise the customize.yaml manual method to get some friendly names and icons. Add the following;

sensor.sensor_inverter_active_power_integral:
  icon: mdi:solar-power
  friendly_name: Solar Generation
sensor.sensor_inverter_export_to_grid_integral:
  icon: mdi:transmission-tower-export
  friendly_name: Grid Export
sensor.sensor_inverter_import_from_grid_integral:
  icon: mdi:transmission-tower-import
  friendly_name: Grid Import

Restart Home Assistant for the sensors.yaml and customize.yaml to be loaded. Make sure SunGather is running, wait 5 minutes for inital data to populate. Navigate to the Energy platform (Configuration > Energy). Add these sensors to the following areas:

Electricity Grid > Grid Import - sensor.sensor_inverter_import_from_grid_integral
Electricity Grid > Grid Export - sensor.sensor_inverter_export_to_grid_integral
Solar Panels > Solar Production - sensor.sensor_inverter_active_power_integral
