Hardy Barth eCHARGE eCB1 measuring point

Central current measurement and control for the Hardy Barth Wallbox. With this control unit, you can conveniently control the charge current of the Wallbox, regardless of the inverter or storage system installed. The measurement is performed independently at the network tie points. Thus, you can only charge the vehicle with PV energy. 

Advantages of eCB1

• Installation in meter cabinet 4 TE
• Interface: LAN and RS485
• Display of the total consumption per phase and in total
• Visualisation via web interface
• 400 V, 3-phase up to 63 A or with transducer measurement up to 600 A
• Dynamic charge current control with pure PV current from 6A per phase in 0.1A steps
• Switching between eco and power charging via the web interface

Compatible system manufacturer for visualisation

If the eCB1 is installed directly at the grid connection point, only the excess energy can be determined. This is the basis for a dynamic vehicle load. But how much energy the car actually charges depends on the charge level of the battery and the charge controller installed there. In order to be able to visualise this information in the portal exactly, a second measuring point on the wallbox is required.

Applications with eCB1

• PV overcharging
• Load management for several wallboxes
