Operation and function
Smart Remote
The Smart Remote function is used for remote access to the controller via a
4-state signal.
The sensor inputs S4 and S5 of the controller are used as switching inputs. The
switching states are On (contact closed) and Off (contact open).

Inverter
This function is used for operating the inverter at reduced power, if the excess
exceeds a threshold. The operation is specified by a switching signal.

The parameter Power can be used for adjusting the nominal power of the inverter.
The threshold is calculated from the adjustable limitation in relation to the power
of the inverter.
Threshold = power x threshold limit
If the average threshold value is continuously exceeded during the adjustable mon-
itoring time, the signal is switched via the potential-free relay R4. If the value falls
below the average value during the monitoring time, R4 switches off.
Note:
This function is only available, if the variant Module has been selected in
the Measuring unit menu.
The control unit reduces the feed-in power of the PV system into the public grid. If
the store is fully loaded (REmax), the full inverter power is available for grid feed-in.
With this function the power can be limited.
