Multi Device Control (MDC) compatibility
The Multi Device Control (MDC) function is available on the PLENTICORE G3 from software version 3.06.10 onwards.
Multi Device Control (MDC) is used to monitor and control MDC-enabled inverters and other MDC-enabled devices in the same home network. The control task is performed by a PLENTICORE G3 inverter that has been configured as an MDC host inverter. An MDC host inverter can be operated with or without a battery. If a battery is used in the system network, the battery with the largest capacity must be connected to the MDC host inverter.
If several PLENTICORE G3 inverters with batteries have been installed in the home network, they can be controlled via an MDC host. To do this, the paid product extension/additional option Battery Control with MDC must be activated on the MDC host inverter. If several batteries have been installed in the MDC system network, the battery with the largest capacity must be connected to the MDC host inverter.
Without the product extension Battery Control with MDC, only one battery can be connected to and controlled by the MDC host inverter.
Controlling and regulating other MDC client inverters is also possible without the product extension if only one battery storage unit is used in the MDC system.
The following devices and functions are supported by MDC
Below is an overview of the devices that can be controlled via MDC. Please note the current software installed on the G3 inverter.
PLENTICORE G3 with Multi Device Control (MDC) from SW3.06.10
From SW version 3.06.10 onwards, the PLENTICORE G3 can now control other G3 inverters with and without batteries that also have SW 3.06.10 installed. This eliminates the need for the current connection of several inverters via a smart meter gateway (KSEM), where all inverters had to be registered in the KSEM. However, not all connections are currently possible with MDC. You will find an overview below.
The column 'Control via KSEM' shows the comparison with control via MDC.

If control in your system network is not possible via MDC because incompatible devices have been installed in the system network, control must be carried out via a KOSTAL Smart Energy Meter (KSEM). Please refer to the document Connecting multiple inverters, which you can find in the download area for the product.
