🔌🚗 QA Wallbox Solax EVC X3 G2
QA Solax EV Charger G2 is an application for communication and control of the new generation Solax EV Charger EVC X3 G2 wallbox. It enables reading operational and status values and direct manual control of charging modes and power.
The application can be used independently as a monitoring and control interface, or integrated as part of home energy management. The application itself does not contain automation logic, but serves as a data and control interface for higher-level applications.
💼 Business Presentation
The application provides an overview of wallbox charging status and operational values and enables its manual control. In standalone operation, it serves as a monitoring and control interface.
For automatic charging control based on PV surpluses, expansion with the QA Řízení spotřeby application is required.
For SPOT price-based charging control, a combination of QA Spot PRO and QA Řízení wallboxu applications is required.
The QA Solax EV Charger Integration application itself does not automatically control charging, but provides communication, data collection, and direct wallbox control for higher-level control systems.
📊 Data Analysis and Management
For clear visualization, working with measurement history, and graphs, we recommend integration with SCADA Mervis.
