# SAJ Solar Inverter

> SAJ Solar Inverter is a built-in integration for Home Assistant. It has 216 installs sharing analytics and works locally.

SAJ Solar Inverter is a built-in integration that connects Home Assistant to SAJ solar inverters. It communicates with the device locally and exposes its readings as sensors. Setup runs in the user interface and asks for the host, connection type, username and password. If an older YAML configuration fails to import, a notice appears under Repairs in Settings.
