Terra AC Wallbox
ABB
Description
The ABB Terra AC Wallbox is a smart AC wallbox for residential and semi-public electric vehicle charging. It integrates into the OS E-Mobility system via Modbus TCP – with dynamic load control, energy monitoring, and PV surplus charging.
Technical Data:
• Charging power: up to 11 kW (3-phase, 16 A) or 22 kW (3-phase, 32 A)
• Integrated energy meter reading: tracking of active power and energy consumption (session and total)
• Optional RFID for starting/stopping charging sessions: (RFID management is handled directly on the wallbox via the TerraConfig app, not via the OS)
• Phase operation: fixed 1-phase or 3-phase (no automatic phase switching)
