Do not connect any loads that require a stable energy supply
The secure power supply operation and the battery-backup operation may not be used for
loads that require a stable energy supply. The energy that is available during the secure
power supply operation or battery-backup operation depends on the battery capacity
available and the state of charge of the battery (SOC).
• Do not connect loads if they are dependent on a stable energy supply for reliable
operation.
Black start function
The inverter has a black start function and an auxiliary battery that provides energy for the black
start. In battery-backup systems, you have the possibility to install a standard switch for black
starting the inverter and battery. The black-start switch is used to start the battery-backup operation
manually in the event of grid failure if the battery and inverter are in sleep mode and, therefore, are
unable to provide energy. When the black-start switch is switched on manually, the energy from the
auxiliary battery is made available in order to automatically switch the battery and therefore also
the inverter from sleep mode to operation in order that the inverter can make energy available from
the battery. You can stop the battery-backup operation by switching it off manually.
SMA Smart Connected
SMA Smart Connected is the free monitoring of the inverter via the SMA Sunny Portal. Thanks to
SMA Smart Connected, the PV system operator and qualified person will be informed automatically
and proactively about inverter events that occur.
SMA Smart Connected is activated during registration in Sunny Portal. In order to use SMA Smart
Connected, it is necessary that the inverter is permanently connected to Sunny Portal and the data
of the PV system operator and qualified person is stored in Sunny Portal and up-to-date.

Installation Manual
Explanation
Waiting for feed-in conditions
The conditions for feed-in operation are not yet met. As soon as the
conditions are met, the inverter will start feed-in operation.
Secure power supply operation or battery-backup function
The secure power supply operation or battery-backup function is ac-
tivated and the inverter supplies the loads with energy from the bat-
tery.
Update of central processing unit
The central processing unit of the inverter is being updated.
Parallel grid operation
