If an optional push-button (not included in the scope of delivery) has been fitted in the
device, the push-button can be used to switch between all modes (except Lock Mode).
With this function, the charging power specified by the customer is made available to the
vehicle for charging.
If there is a PV surplus at the grid interconnection point, the amount drawn from the grid is
replaced by the PV power or, if possible, increased to the PV surplus.
If desired, a minimum PV surplus power can also be defined here. This is the minimum level
which must be present before charging is started at the power level defined by the cus-
tomer. If the surplus power falls below the defined minimum value, charging is stopped
again.
This function can be used to charge the electric vehicle in the evening, for example, when
there is no longer enough PV energy available but the electric vehicle needs to be charged
for the next morning.

PV surplus
This surplus can also be used to charge a battery.

Max. wallbox charging power 11 kW (3-phase).
3
Fixed minimum starting charging power
In this example, at 50 % of the max. charging power of 11 kW (for 3-phase connec-
tion with 3-phase vehicle = 5.5 kW).
4
Set min. surplus power at the grid connection point before charging is started. In this
example, 60 % of 5.5 kW = 3.3 kW.
The additional charging power of 2.2 kW (5) is drawn from the public grid.
5
Charging electric vehicle from the public grid. In this example 2.2 kW.
6
Charging electric vehicle from PV surplus.
