Setting up MDC clients in the MDC host

The MDC client inverters are integrated via the device manager of the MDC host inverter.

The device manager is only displayed on the inverter that has been configured as the MDC host inverter. The decision as to whether an inverter is operated as an MDC host or MDC client inverter is made during initial commissioning. Alternatively, the setting can be changed later via the Change operating mode menu item.

Under the Device Manager menu item, you will see all available devices that have been detected by the MDC host within the home network.

INFO

Dual control/regulation

If control via Multi Device Control is activated, control via the KOSTAL Smart Energy Meter (KSEM) is no longer possible. All devices that were previously controlled via the KSEM must be removed from the KSEM under the Inverter menu item and connected to the MDC host via the Device Manager. Any active power limitation in the KSEM must be deactivated and reconfigured in the MDC host.

If there are incompatible devices on the home network that can only be controlled via the KSEM (e.g. PLENTICORE plus G1), MDC cannot be used for control. In this case, all devices must be configured in the KSEM.

There are two ways to connect devices to the MDC host.

Manual connection by entering all values
Select device from the list and connect

Use the ‘Add manually’ option to connect the devices to the MDC Host inverter. You must enter the device values manually. Depending on the device, it can then either be read out or controlled.

If you select a device from the ‘Available Devices’ list, you can connect it to the MDC Host inverter after filling in the necessary fields.

A red X means that the connection cannot be established or that an error has occurred. Clicking on the device opens the settings, which can be adjusted. Selecting ‘Disconnect’ disconnects the device from the MDC host, and the device can no longer be controlled by the MDC host. Under ‘Info’, you can view the current performance metrics for the device.
