Digital Multi Control

Generator support with external transfer switch

For a system with a MultiPlus together with an external transfer switch, the control panel can be configured to allow the AC current to be changed while the system is connected to the grid but has a fixed AC current limit when connected to a generator.

The panel sends the current limit to the inverter/charger system as set via the knob. If the screw terminals on the panel's back are short-circuited, a preset current limit is sent instead, and "GEN" is displayed.

To enable this, connect the screw connector terminals to an externally controlled switch, typically the auxiliary relay of an external transfer switch. For setup, refer to the Generator current limit chapter.

This feature is not relevant to a standard Quattro setup, which does not need an external transfer switch, and a fixed generator AC input limit can be configured in the Quattro.
