SolarEdge Modbus data collection library

Home Assistant customcomponent for SunSpec modbus devices

HA Custom Component to integrate data from ABB/Power-One/FIMER PV Inverters that support SunSpec Modbus (Sunspec M1, M101, M103, M160), natively or through the VSN300 wifi logger card.

Home Assistant integration for SunSpec Modbus devices. Based on pysunspec2 1.3.x

ABB/FIMER PVI inverters - VSN300/VSN700 REST API integration for Home Assistant

A local-first Home Assistant integration for FranklinWH power systems

FranklinWH Modbus Battery Control Library & Web Manager

ProjectEnergy32: read SolarEdge inverter values using SunSpec / Modbus TCP, publish to MQTT (Python version)

SunSpec Modbus → MQTT/InfluxDB bridge for Fronius inverters and smart meters. Home Assistant autodiscovery, monitoring dashboard with per-inverter power-limit control.

CreaBus Tool — a Modbus simulator and client in one window, over TCP and RTU. Test against industrial devices with none of them on the desk.

DERIM (Distributed Energy Resource Integration Middleware) is an open-source, modular middleware platform that bridges the gap between heterogeneous distributed energy resources (DERs) and modern smart grid management systems. It ingests real-time data from solar PV inverters, battery energy storage systems, and EV charging stations with standars

Local SolarCity/Tesla collector replacement for Power-One PVI-5000-OUTD-US-Z via Digi XBee and SMLIGHT

Reverse-engineered SunSpec Modbus map of the APsystems ECU-C (firmware C1.2.26): every register with its implementation status, an undocumented model hidden after the end-of-chain marker, and a silent failure mode that breaks zero export. Probe scripts and Home Assistant config included.

☀️ Open-Source-Dashboard für PV-Anlagen aller Hersteller – Live-Energiefluss, PV-Prognose, Strompreise und Tipps. Self-hosted mit Docker, läuft auf dem Raspberry Pi.

Home Assistant integration for Steca inverters (Kostal Plenticore platform): reads via SunSpec/Modbus TCP and the Kostal web API, and dynamically curtails feed-in power against a grid sensor.

This project shows a dashboard with relevant parameters such as a battery energy for a solar car.

A reproducible bench for Pylontech CAN to SunSpec Modbus bridging, and five places where "compatible" implementations disagree.

FIMER (ABB / Power-One) PV inverters - Modbus TCP SunSpec integration for Home Assistant

Monitor and control KACO solar inverters in Home Assistant over SunSpec Modbus TCP

Home Assistant integration for Fronius inverters, storage systems and smart meters using SunSpec Modbus TCP.
