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. The smart meters from various manufacturers, some of which are already installed on the mains supply, can be used for this purpose. The eCB1 can be combined with the following manufacturers:

  • SMA Energy Meter-20 or Home Manager 2.0
  • Fronius inverter incl. Fronius Smart Meter
  • Kostal Plenticore + Piko IQ

Applications:

  • PV overcharging
  • Load management for several wallboxes

Scope of delivery:

  • Hardy Barth Wallbox cPµ1 T2 11 type 2
  • Hardy barth Smart Meter eCB1-LR-PV measurement and control unit

For the control, a data line between smart meter and wallbox is required (e.g. CAT 5e)
