Description
The user interface of the inverter is used to configure and monitor the
system, but primarily the inverter and battery.
If there are multiple inverters installed, one inverter can be configured
as the System Manager. The user interface of the System Manager is
used to configure and monitor all inverters and batteries in the sys-
tem.
If there is an SMA Data Manager installed, the SMA Data Manager
is configured as the System Manager. The user interface of the Sys-
tem Manager is used to configure and monitor all inverters and bat-
teries in the system.
The LEDs indicate the operating state of the inverter.
The battery management system display is used to make some basic
settings during commissioning of the battery. The display also shows
the event messages for the battery.
The external switch on the battery cabinet door and the SWITCH
control element on the battery management system are used for com-
missioning and for disconnecting the battery from voltage sources.
The LED in the SWITCH control element on the battery management
system indicates the battery operating state.
