KOSTAL introduces Multi Device Control (MDC) for PLENTICORE G3

KOSTAL is expanding the range of applications for its PLENTICORE G3 inverter series with the new Multi Device Control (MDC) function. With MDC, up to three inverters can be controlled and monitored centrally via a single PLENTICORE unit. The aim is to simplify the implementation of complex photovoltaic projects – such as those involving challenging roof surfaces or increased storage requirements – as well as to reduce installation and configuration efforts.

Multi Device Control is currently available for PLENTICORE G3 and PLENTICORE MP G3. KOSTAL is continuously developing the function – with plans to support further compatible inverters, such as the PIKO CI, in the future. MDC can be used from software version 3.06.10 onwards.
 

One system. One control unit. Full control. 

In an MDC network, a PLENTICORE G3 acts as the MDC host, taking on the central control and monitoring of all integrated MDC-enabled devices (clients) in the home network. Additional inverters are integrated directly via the device manager in the host’s web interface – simply, quickly and without additional system logic.
Important: System management is carried out exclusively via the MDC host. Control via KSEM or other external energy managers is not permitted in the MDC network and must not take place in parallel.
 

Optimised storage strategy for balanced utilisation 

By default, a battery system is connected to, operated and controlled by the MDC host. With the optional ‘Battery Control with MDC’ product extension, up to three storage systems can be integrated – one storage system per inverter. A storage system may also consist of several battery towers connected in parallel and is treated by the system as a single unit.

The charging and discharging power is intelligently distributed across the connected storage systems, ensuring the most consistent State of Charge (SoC) possible across all storage units. This ensures optimal utilisation of the total capacity and increases system efficiency.
 

Backup operation: clear priority, clear logic 

In the event of a backup, only the storage system connected to the MDC host is used. The other inverters in the network are not activated in this operating mode and do not feed into the grid. Parallel control of multiple inverters in backup mode is not currently planned.
 

Ready for grid requirements and dynamic tariffs 

The MDC Host can centrally process curtailment signals and distribute them to all clients. Furthermore, the system supports modern requirements, including the use of dynamic electricity tariffs.
The entire system is clearly displayed as a power flow diagram on the screen and on the MDC Host’s web server. Furthermore, by enabling data transmission to the KOSTAL Solar Portal, the entire system can be managed in a single overview.
 

KOSTAL MDC: simple, efficient, intelligently controlled 

With the new MDC function, KOSTAL lays the foundation for more efficient systems, better utilisation of storage capacity and the simple implementation of modern requirements such as dynamic tariffs.

This is because the central control of up to three PLENTICORE G3 inverters significantly reduces complexity during planning, commissioning and operation. At the same time, the enhanced battery management enables a flexible and scalable storage strategy – particularly for larger and more sophisticated PV systems. A clear added value for installers and operators alike.
