Witty charging control, house load limitation + 3-phase PV CHP charging. Charging control module for use with Hager charging station and for installation in the meter cabinet. The module enables dynamic adjustment of the charging current of the charging station to the available free capacity of the house installation in order to avoid overloading. If the set limit is exceeded, the vehicle's charging current is reduced until charging is interrupted. Alternatively, the device can also be used for targeted charging of energy generated from renewable sources (PV, CHP). The current transformer is attached to the feed-in line for this purpose. After connecting a vehicle, the charging station waits until the minimum current is exceeded and then starts charging and dynamically follows the current fed in. Charging control module consisting of DIN series-mounted devices with 3 transformers. Possible adjustable limit values for the entire installation from 15 to 100 A. Note: A two-wire connection to the charging control module in the charging station is required.
