Operating mode

INFO

The settings in this menu can only be configured after logging in as the installer.

The connected system components are selected when the inverter is commissioned for the first time.

If the selection needs to be changed at a later date, e.g. because a battery has been added, the initial commissioning can be restarted here. As soon as the Change operating mode button is pressed, the device is restarted and the initial commissioning must then be carried out again.

Under Operating mode, select which components are to be included in the initial setup (PV generators, installed energy meter, connected battery, a connected backup unit manually or automatically).

Parameter	Explanation
PV strings	PV generators are connected to the inverter.
Energy meter	An energy meter is fitted at the grid connection point and communicates with the inverter (e.g. a KOSTAL Smart Energy Meter).
Battery	A battery is connected to the inverter.
BackUp Switch	A Manual BackUp Switch from KOSTAL, which disconnects the public grid from the house grid, has been fitted at the grid connection point. The manual switch transmits the status of the changeover to the inverter via a signal cable.
Backup box	An automatic backup box, which disconnects the public grid from the house grid, has been fitted at the grid connection point. The automatic backup box transmits the status of the changeover to the inverter via a signal cable.
Information about MDC	For inverters configured as an MDC client or MDC host, information about the configuration is displayed here. MDC: Host The inverter has been configured as an MDC host without extended battery control. The MDC host can take over control of other MDC client inverters without a battery. In this case, only one battery may be connected to the MDC host. MDC: Host with “Multi Battery Control” The inverter has been configured as an MDC host with additional battery control. The MDC host can take over battery control of two further MDC client inverters with a battery connected. MDC: Client The inverter has been configured as an MDC client and can be controlled by an MDC host inverter. No display The inverter is configured as a stand-alone unit (stand-alone inverter) without MDC.
