Procedure for multicluster systems with battery-backup grid
With the Multicluster Box 12 (MC-Box-12.3-20) and the NA Box or Grid Connect Box, multicluster systems with
battery-backup grid can be installed (see Multicluster Box and NA Box / Grid Connect Box documentation).
• In a multicluster system with battery-backup grid, set the ranges of battery state of charge for each cluster to the
same values.
You can change the battery usage through battery-backup systems with increased self-consumption on the communication
product or Sunny Remote Control.
Procedure:
1. Log in to the communication product as Installer (see the user manual of the communication product) or switch to
expert mode on the Sunny Remote Control (see the Sunny Island operating manual).

Behavior of the Sunny Island inverter
The Sunny Island switches into standby mode.
The Sunny Island starts up every two hours and
attempts to charge the battery with PV energy.
If the battery cannot be charged, the
Sunny Island switches back to standby mode.
When the utility grid is available, the
Sunny Island charges the battery with nominal
power from the utility grid.
When this range is reached, the Sunny Island
switches off in order to protect the battery.
When the utility grid is available again, the
system must be charged manually ("Charging
the Battery after Auto Power Off", see
Sunny Island operating manual).
