Hardy Barth eCHARGE eCB1


Central current measurement and control for the ABL eMH1 Basic WallboxWith this control unit you can conveniently control the charging current of the wallbox, regardless of which inverter or storage system is installed. The measurement takes place independently at the network connection point. Therfore you can exclusively charge the vehicle with PV energy


Benefits of eCB1

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

Compatible inverters and monitoring systems


Due to the compatibility with the following manufacturers, the data can be taken over from the network connection point. With this, you can use the eCB1 to measure the actual charging power at the charging point.

  • SMA Energy Meter and Home Manager 2.0
  • SolarEdge with Modbus counter via Modbus TCP
  • Fronius with Smartmeter via Modbus TCP
  • gridX via Modbus TCP 

Compatible billing systems
