A standalone background service for managing and monitoring a SolaX X3-HYB-G4 PRO hybrid inverter and a SolaX X1/X3-HAC EV charger. It operates entirely within the local network over Modbus TCP, with no cloud dependency, so polling is immediate and the data stays on the premises.
It reads PV generation, battery state of charge and grid power flow, and uses them to drive EV charging and home-battery use from household surplus: charging the car on live solar, holding the battery back when the forecast says it will be needed, and targeting a departure time. A web UI is built in, and it can publish itself to Home Assistant over MQTT.
The built-in web interface requires a password. A fresh installation serves only the page that asks you to set one, and shows no history and no controls until you have; it then asks you to sign in. Authentication can be switched off deliberately for an isolated network, which is not the default. The interface speaks plain HTTP, so it belongs on a network you trust or behind a TLS proxy.
