Procedure for multicluster systems with battery-backup grid
All systems for which VDE-AR-N 4105-11:2018, EN50549-1:2018, C10/11:2019, G98-1:2018, G99-1:2018,
CEI 0-21:2019 type A/type B, TOR generator type A of the European grid connection regulations according to
Regulation (EU) 2016/631 are subject shall not be set up as multicluster systems.
Multicluster systems with battery-backup grid can be set up with the Multicluster-Box 12 (MC-Box-12.3-20) and
the Grid-Connect-Box (see documentation of the Multicluster-Box and Grid-Connect-Box). When doing so, always
perform the following steps:
• In a multicluster system with battery-backup grid and increased self-consumption, set the ranges of battery
state of charge for each cluster to the same values.
• In a multicluster system with battery-backup grid and without increased self-consumption, always set the
Internal consumption increase switched on
parameter to
No
.
If the values for the battery usage ranges are incorrect, no adjustment is possible
If all battery usage ranges combined exceed 100%, the parameters for battery usage cannot be set.
• Ensure that all battery usage ranges combined result in the value 100%.
The basic procedure for changing operating parameters is explained in another section (see Section 8.6, page 113).
