Multiple-inverter connection of KOSTAL inverters
With battery storage
Without battery storage
In a multiple-inverter connection, up to 10 KOSTAL inverters can be used in the same house grid.
Only one KOSTAL Smart Energy Meter is required to monitor power and limit feed-in at the grid connection point. This is installed at the grid connection point in the house grid as shown in the illustrations.
INFO
In a device network comprising several KOSTAL inverters, the data is merged in the portal. Correct and complete visualisation can only be found in the KOSTAL Solar Portal and in the KOSTAL Solar App and not in the individual inverter.
To visualize the overall data, the KOSTAL Smart Energy Meter and all KOSTAL inverters must be added in the KOSTAL Solar Portal as devices of a PV system.
Approved KOSTAL inverters for a multiple-inverter connection with battery storage
In a multiple-inverter connection with battery storage, a maximum of one hybrid/battery inverter (PLENTICORE or PLENTICORE BI) with connected battery may be used.
