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)
