You can connect a potential-free switch (e.g. key switch or ripple control receiver) to one of the two S0 inputs on the cFos Power Brain Wallbox, e.g. to S0-2
, as shown in our documentation on S0 meters
. You can then query this input using charging rules
and thus influence the charging. Some network operators / energy suppliers require that the charging power of the wallbox(es) can be reduced or set to 0 by means of ripple control receivers if necessary. In order to fulfil this requirement for grid-serving control, you can enter a formula as follows in the Charging Manager settings for the parameter "Max. total power (W)" instead of a fixed value: PB.input2 ? 25000 : 0
If the S0-2 input is set (switch closed), the Charging Manager takes 25 kW as the house connection power, otherwise 0 kW. You can adjust the specific power values according to your application.
