Read data from SolarEdge Inverter and publish it to MQTT

SolarEdge 2 MQTT Service

The SolarEdge2MQTT service is a project designed to read power data from a SolarEdge inverter and publish it to an MQTT broker. The service is useful for integrating SolarEdge inverters into home automation systems or other applications that use MQTT for data exchange. It provides real-time monitoring of power flow and other parameters from the inverter via Modbus.

You can also gather the panels' energy production data from the SolarEdge monitoring site. This feature is optional and does not use the API, but rather your monitoring platform account.

The SolarEdge Wallbox can be monitored as well via REST API.

Additionally all values can be saved for visualization into a InfluxDB.

The SolarEdge2MQTT service is currently in an early stage of development. While it is functional and can be used to read data from a SolarEdge inverter and publish it to an MQTT broker, it is still undergoing active development. Features may be added, removed, or changed, and there may be bugs. Users should be aware of this and use the service with caution. Despite its early state, the project is open-source and contributions are welcome.

Installation and Configuration

Install and update using pip.

pip install -U solaredge2mqtt

Install and update using docker

docker pull ghcr.io/deroetzi/solaredge2mqtt:latest

Service configuration

The service is configured by environment variables. The following options can be set:

Basic configuration

Environment Variable	default	description
SE2MQTT_INTERVAL	5	Interval between requests in seconds
SE2MQTT_LOGGING_LEVEL	INFO	Set logging level to DEBUG, INFO, WARNING, ERROR, CRITICAL

Modbus configuration

Environment Variable	default	description
SE2MQTT_MODBUS__HOST	None	IP address of your inverter
SE2MQTT_MODBUS__PORT	1502	Modbus port of your inverter
SE2MQTT_MODBUS__TIMEOUT	1	Timeout for the modbus connection
SE2MQTT_MODBUS__UNIT	1	Modbus unit address

MQTT configuration

Environment Variable	default	description
SE2MQTT_MQTT__CLIENT_ID	solaredge2mqtt	MQTT client id
SE2MQTT_MQTT__BROKER	None	IP address of your MQTT broker
SE2MQTT_MQTT__PORT	1883	Port of your MQTT broker
SE2MQTT_MQTT__USERNAME	None	Username to authenticate to your MQTT broker
SE2MQTT_MQTT__PASSWORD	None	Password to authenticate to your MQTT broker (for security reason use secrets with docker)
SE2MQTT_MQTT__TOPIC_PREFIX	solaredge	SolarEdge2MQTT will use this as prefix topic

Monitoring

If you want to get panel energy values from the SolarEdge monitoring platform, add additional parameters.

Environment Variable	description
SE2MQTT_MONITORING__SITE_ID	Your site id from the SolarEdge monitoring plattform
SE2MQTT_MONITORING__USERNAME	Your username for your account on the SolarEdge monitoring platform
SE2MQTT_MONITORING__PASSWORD	Your password for your account on the SolarEdge monitoring plattform (for security reason use secrets with docker)

If you want to monitor the power values of your SolarEdge Wallbox, add additional parameters. The Wallbox needs to have firmware version >= 1.15.0 and activated REST API.

Wallbox

Environment Variable	description
SE2MQTT_WALLBOX__HOST	The IP adress of your wallbox
SE2MQTT_WALLBOX__PASSWORD	The password of user admin you use to login the Web UI of your Wallbox
SE2MQTT_WALLBOX__SERIAL	The serial number of your wallbox

InfluxDB

If you want to save the monitoring data to a InfluxDB you have to generate a full access token, because the service will generate two buckets and a task for you.

The first bucket (raw) is used to store every interval the data of the components inverter, meters, batteries and wallbox to a measurement called component and the current powerflow state. This can be useful for debugging reasons. The generated aggregation task will store the energy values of every minute to this bucket. By default this bucket holds the values for 24h.

The second bucket is used by the aggregation task to store the powerflow states and energy values aggregated by 1 hour intervals. By default this bucket holds the values for 2 years.

Environment Variable	default	description
SE2MQTT_INFLUXDB__HOST	None	Set your host (for example: http://localhost)
SE2MQTT_INFLUXDB__PORT	8086	Set your port
SE2MQTT_INFLUXDB__TOKEN	None	Set your token (for security reasons use a secret with docker) The token must have full access because the service manages the needed buckets and tasks
SE2MQTT_INFLUXDB__ORG	None	Set your organization ID
SE2MQTT_INFLUXDB__PREFIX	solaredge/solaredgedev	Set a prefix for bucket and task names
SE2MQTT_INFLUXDB__RETENTION_RAW	90000 = 25h	Set a retention policy in seconds for bucket raw
SE2MQTT_INFLUXDB__RETENTION_AGGREGATED	63072000 = 2 years	Set a retention policy in seconds for bucket aggegrated
SE2MQTT_INFLUXDB__AGGREGATED_INTERVAL	10m	Aggregate power and energy valuse in InfluxDB set a interval for the task should be between 10m and 1h

Forecast

The service can read forecast estimations from forecast.solar. You can setup information for 1 or 2 strings, and you need an API-key. See forecast.solar documentation for more information about settings. If you have configured influxdb power and energy forecast will be saved for visualization as well.

Environment Variable	description
SE2MQTT_FORECAST__LATITUDE	Set latitude for forecast values
SE2MQTT_FORECAST__LONGITUDE	Set longitude for forecast values
SE2MQTT_FORECAST__API_KEY	Set your API key for forecast values from https://forecast.solar/ (for security reasons use a secret with docker)
SE2MQTT_FORECAST__STRING1__PEAK_POWER	Set values for the forecast calculation of string 1
SE2MQTT_FORECAST__STRING1__DECLINATION	Set values for the forecast calculation of string 1
SE2MQTT_FORECAST__STRING1__AZIMUTH	Set values for the forecast calculation of string 1
SE2MQTT_FORECAST__STRING2__PEAK_POWER	Set values for the forecast calculation of string 2 (you need at least a Personal Plus plan for a second string)
SE2MQTT_FORECAST__STRING2__DECLINATION	Set values for the forecast calculation of string 2 (you need at least a Personal Plus plan for a second string)
SE2MQTT_FORECAST__STRING2__AZIMUTH	Set values for the forecast calculation of string 2 (you need at least a Personal Plus plan for a second string)

Example configuration

You can download .env.example and rename it to .env. Inside, you can modify the default configuration values to meet your needs in this file.

Run the service

In the console

Copy the .env.example file to .env and modify it according to your needs.

Then, simply run solaredge2mqtt to start the service.

With docker:

docker run --name solaredge2mqtt --rm \
    -e "SE2MQTT_MODBUS__HOST=<INVERTER_IP>" \
    -e "SE2MQTT_MQTT__BROKER=<BROKER_IP>" \
    -e "SE2MQTT_MQTT__USERNAME=<MQTT_USERNAME>" \
    -e "SE2MQTT_MQTT__PASSWORD=<MQTT_PASSWORD>" \
    -e "TZ=Europe/Berlin" \
    ghcr.io/deroetzi/solaredge2mqtt:latest

Add optional environment arguments from above to fit to your setup.

With docker-compose

Copy the .env.example file to .env and modify it according to your needs.

Get the docker-compose.yml file.

Generate a .secrets directory and put at least a file called mqtt_password inside with your MQTT broker password.

If you want to use module energy values additionally, uncomment the secrets parts for the se2mqtt_monitoring__password secret inside the docker-compose.yml file and place an monitoring_password file in the .secrets directory. The same applies to wallbox_password and influxdb_token. These are the minimum secrets you should use. Feel free to extend it with other parameters such as usernames, site_id, and location.
