Heidelberg Connect Charging Station

Three-phase or single-phase AC charging station with Modbus integration.

Overview

This bundle provides integration with the Heidelberg Connect electric vehicle charging station, a flexible AC charging solution supporting both single-phase and three-phase configurations. The station communicates via Modbus for integration with energy management systems, offering phase-switching capability for dynamic load balancing.

Heidelberg Connect is suitable for commercial charging networks, workplace charging, and residential installations requiring flexible single/three-phase charging.
