Device network control via MDC
Please note:
- A G3 inverter must be configured as the MDC host during initial setup. 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.
- A maximum of 1 inverter with a connected battery may be used in the device network if the paid product extension ‘Battery Control with MDC’ has not been activated.
- A maximum of 3 inverters with connected batteries may be used in the device network. In this case, the paid product extension ‘Battery Control with MDC’ must be purchased and activated.
- Only the devices listed in the table are approved for use with an MDC system.
- A KEM or KSEM must be connected to and configured on the MDC host inverter.
- The energy meter must be installed at the grid connection point.
- Inverters may no longer be configured in the KSEM. This is done exclusively in the device manager of the MDC host inverter.
- Control via the KSEM or another or external energy management system is not possible.
- Power monitoring or dynamic limitation of the feed-in power (e.g. to 60%) at the grid connection point is configured only in the MDC host for all inverters.
- The power flow diagram for the entire system is clearly displayed only on the web server and on the display of the MDC host inverter. The MDC client inverters display only the instantaneous values of the respective MDC client inverter.
- All inverters must be configured to send their data to the KOSTAL Solar Portal. If an MDC host is used in conjunction with a KOSTAL Smart Energy Meter (KSEM), the KSEM does not need to send its data to the KOSTAL Solar Portal.
Device network
The following KOSTAL inverters can be used in a device network.
Type | Inverter |
|---|---|
|
PLENTICORE G3 with battery |
|
PLENTICORE G3 without battery
|
System consisting of PV inverters without the ‘Battery Control with MDC’ product extension on the MDC host
Device network consisting of PV and hybrid inverters without the “Battery control with MDC” product extension on the MDC host
Device network consisting of PV and hybrid inverters with the “Battery control with MDC” product extension on the MDC host
In this configuration, the inverter with the largest battery must be the MDC host. In this case, the MDC host can control up to two additional PLENTICORE G3 inverters with connected batteries.
