Open Dynamic Export

Getting started ​

Introduction ​

Open Dynamic Export is a Node/TypeScript project implementing dynamic export control/solar curtailment of inverters. It aims to solve these use cases:

  • dynamic connection requirements (CSIP-AUS/SEP2/IEEE 2030.5) of various Australian energy distributors (DNSPs)
  • fixed/zero export limitations (e.g. 1.5kW export limit)
  • two-way tariffs (e.g.time based) export limitation
  • negative feed-in (e.g. Amber) export limitation

Architecture ​

Limiters ​

The system uses one or more "limiters" to set the operating envelope of the site. All limiters are restrictive, that is a combination of multiple limiters will evaluate all limiters and enforce the most prohibitive value of each control type at any one time. Learn more about configuring limiters.

Inverters ​

The system supports one or more inverters to measure the site's generation metrics and control the power output. Learn more about configuring inverters.

Site meter ​

The system supports one site meter to measure the site's load and export metrics. Learn more about configuring site meter.

Install ​

Docker compose ​

  1. Clone Git repo

  2. Copy .env.example and rename it to .env and change the values to suit your environment

yaml
TZ=Australia/Melbourne # Your system timezone
SERVER_PORT=3000 # API server port
CONFIG_DIR=./config # Directory to store configuration files
SEP2_CERT_FILE=sapn_cert.pem # CSIP-AUS/SEP2 certificate file (in the config directory)
SEP2_KEY_FILE=sapn_key.pem # CSIP-AUS/SEP2 key file (in the config directory)
SEP2_PEN=62223 # CSIP-AUS/SEP2 Private Enterprise Number
INFLUXDB_USERNAME=admin # InfluxDB username
INFLUXDB_PASSWORD=password # InfluxDB password
INFLUXDB_ADMIN_TOKEN=super-secret-auth-token # InfluxDB admin token
INFLUXDB_ORG=open-dynamic-export # InfluxDB organisation
INFLUXDB_BUCKET=data # InfluxDB bucket
INFLUXDB_PORT=8086 # InfluxDB port
LOGLEVEL=debug # Log level (valid values: trace, debug)

  1. In the /config folder, make a copy of the config.example.json file and rename it to config.json. Update it with the relevant values, see the "Configuration" section for more details.

  2. Run docker compose up -d (optionally run docker compose up -d --build to build the image from the source code)
