This repository provides a Home Assistant custom component (solax_modbus) that integrates solar inverters from multiple brands (SolaX, Growatt, Sofar, Solis, SRNE, etc.) via Modbus TCP/serial/RTU. It exposes real-time sensor data, battery status, energy totals, and control entities (numbers, selects, switches, buttons, time) into Home Assistant. The component features a plugin architecture where each inverter brand has its own module defining entity descriptions, register maps, and inverter detection logic. It includes an energy dashboard virtual device that aggregates grid, solar, battery, and home consumption for the native Home Assistant Energy Dashboard. Advanced capabilities include remote power control (VPP modes), autorepeat loops, parallel master-slave support, and automatic bad-register quarantine. The codebase is well-tested with unit tests and CI/CD, but suffers from some duplication across plugins and hardcoded register maps.
