Access ModBus data from almost any network connected Sungrow Inverter.
On first connection the tool will query your inverter, retrieve 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 multiple export locations out of the box:
- Console - Log directly to screen
- MQTT - Load into MQTT, and optionally Home Assistance including Discovery
- PVOutput - Load into PVOutput.org
- InfluxDB - Load data directly into InfluxDB (v1.8 or v2.x)
- Prometheus - Scrape from /metrics endpoint
- Simple webserver showing collected data
- Rasberry Pi Docker support
- and more coming....
I have learned a lot from the following projects, THANK YOU
- Full Home Assistant integration, as HACS addon
git clone https://github.com/bohdan-s/SunGather.git
cd SunGather
pip3 install --upgrade -r requirements.txt
Copy config-example.yaml to config.yaml, change values as required (see comments in file)
cd SunGather
copy config-example.yaml config.yaml
Run SunGather:
python3 sungather.py
docker run options:
-v {path to}/config.yaml:/config/config.yaml <- Set Config File Location
-v {logpath}:/logs <- Set Log folder Location if using log to file (also set log_file in config.yaml)
-e TZ=Australia/Sydney <- Set Timezone
-p 8080:8080 <- Set Web server port (only if using the webserver export)
docker pull bohdans/sungather
docker run -d --name sungather \
--restart always \
-v {path to}/config.yaml:/config/config.yaml \
-v {logpath}:/logs \
-e TZ=Australia/Sydney \
-p 8080:8080 \
bohdans/sungather
Note: replace Australia/Sydney with relevant timezone
See config-example.yaml it contains default options and comments.
If you want to use the new Energy section in Home Assistant, follow the Home Assistant setup below.
usage: python3 sungather.py [options]
Commandline arguments override any config file settings
-c config.yaml - Specify config file.
-v 30 - Logging Level, 10 = Debug, 20 = Info, 30 = Warning (default), 40 = Error
--runonce - Run once then exit
-h - print this help message and exit (also --help)
Example:
python3 sungather.py -c /full/path/config.yaml
A collection of exports are available:
- console: Output information to console, useful for troubleshooting
- webserver: Output to a simple website, default http://localhost:8080 or http://<serverip>:8080
- mqtt: Output to a pre-existing MQTT server, needed for Home Assistant integration
- pvoutput: Output to PVOutput.org, requires account and solar is set up on website first.
- InfluxDB: Output directly to InfluxDB, can then be used by Grafana, etc..
This tool should be able to access most registers exposed. Set the following in config.yaml under inverters section.
-
level: 1 - This is the most useful data for day to day
-
Level: 2 - This should be everything your inverter supports
-
Level: 3 - This will try every register, you will get lots of 0/65535 responses for registers not supported.
-
smart_meter: True - (Only needed for SG* Models) Set to true if you have a smart meter installed, this will return power usage at the meter box, without it you can not calculate house power usage. Hybrid inverters will provide this by default (load_power_hybrid)
This is just a brief list of registers I have found useful
daily_power_yields - Total Power in kWh generated today
total_power_yields - Total Power in kWh generated since inverter install
total_running_time - Total Hours inverter has been powered on since install
internal_temperature - Internal temperature of the Inverter
total_active_power - Current power being generated by the inverter in Watts
meter_power - (SG* Models)Power usage at the meter box, needs a smart meter installed. +ve means consuming from the grid, -ve means exporting to the grid
load_power - Power being consumed in total
load_power_hybrid - (SH* Models only) Power being consumed in total
export_to_grid - How much being currently exported to the grid.
For SG* Models this is calculated from meter_power if -ve value, returned as a positive value. (For Hybrid models export_power_hybrid is used)
import_from_grid - How much being currently imported from grid. This is calculated from meter_power if +ve value (_for hybrid models export_power_hybrid [will be negative when importing from grid] is used)
timestamp - Last time data was collected, based on Inverters clock by default
In the SunGather config.yaml you need to set the smart_meter if you have one
For Hybrid Models smart_meter doesn't need to get enabled
# Only for SG* Models
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
The Inverter reports Power (W), but HA needs Energy (Wh). You can use a "Riemann sum integral" (called integration) to convert it. Put the following into your sensors.yaml
sensor:
- platform: integration
source: sensor.inverter_active_power
name: Solar Production (Sungather)
- platform: integration
source: sensor.inverter_export_to_grid
name: Return to Grid (Sungather)
- platform: integration
source: sensor.inverter_import_from_grid
name: Grid Consumption (Sungather)
The additional sensors then setup in HA are the following with Wh unit of measurement for the Energy platform.
Solar Production (Sungather)
Return to Grid (Sungather)
Grid Consumption (Sungather)
Restart Home Assistant for the sensors.yaml to be loaded. Make sure SunGather is running, wait 5 minutes for initial data to populate. Navigate to the Energy platform (Configuration > Energy). Add these sensors to the following areas:
Electricity Grid > Grid Consumption -> Grid Consumption (Sungather)
Electricity Grid > Return to Grid -> Return to Grid (Sungather)
Solar Panels > Solar Production -> Solar Production (Sungather)
