Dbus Enphase Service

A virtual device for the Victron Energy ecosystem that retrieves real-time data from the Enphase web service and makes it available on the Victron D-Bus. This service enables seamless integration of Enphase energy production data into Victron systems for monitoring and analysis.

Features

• Retrieves power and energy production data from Enphase microinverters.
• Publishes data to Victron’s D-Bus for compatibility with Victron monitoring tools.
• Configurable via an external config.ini file for authentication and network setup.

Use Cases

• Hybrid Systems: Monitor Enphase production data alongside Victron installations.
• Energy Insights: Integrate Enphase inverter data into Victron GX devices.

Installation

wget https://github.com/falcovd/dbus-enphase/archive/refs/tags/v1.0.0.zip # replace v1.0.0 with the latest release
unzip v1.0.0.zip
cd v1.0.0
chmod +x install.sh && ./install.sh

Configuration

The config.ini file contains:

• Auth Section:
  • token: Enphase API access token.
• Network Section:
  • ip_address: IP address of the Enphase system.

Limitations

In this version there are some limitations, because I have developed the system primarily for my own use. The limitations are:

• Only metering and parsing 1 phase
• Hardcoded 230V on L1 Voltage
• Calculating Amps from L1 - (PV production / 230)
• Hardcoded maximum power 4350W (my PV capacity)

Development

Prerequisites

• Python 3.x
• Victron's velib_python library (included in submodule)

Testing

Run the script to simulate the D-Bus service and test its functionality:

python3 dbus_enphase_service.py
