Heidelberg / Amperfied Energy Control The Heidelberg Energy Control is a robust AC wallbox for intelligent residential charging. It integrates via Modbus RTU into the E-Mobility system of the OS – including dynamic load management, energy monitoring, and PV surplus charging. Its integrated RS485 interface also allows for local load management with multiple units.

Technical Data:

  • Charging power: up to 11 kW (3-phase, 16 A).

  • Load management: Integrated communication interface for networking up to 16 wallboxes.

  • Firmware requirement: Active control of charging power via the OS is only possible from version 1.0.7 onwards.

  • Phase operation: Fixed 1-phase or 3-phase (no automatic switching between 1-phase and 3-phase operation possible).
