5.4.11 Peak load shaving
With the "Peak Load Shaving" function, you can optimize the behavior of the battery inverter with respect to the power
exchange at the point of interconnection. This is mostly useful when a higher supply of energy would lead to a higher
electricity cost. With the "Peak Load Shaving" function, certain grid-exchange power outputs to which the battery
inverter is adjusted depending on its power and battery capacity available can be set. Power peaks and additional
costs can thus be avoided.
You can configure setpoints for the power drawn at the point of interconnection. When the loads require additional
energy, the battery is discharged and the maximum value is kept constant at the grid-connection point. This is based on
the prerequisite that the battery is sufficiently charged.

Explanation
No country data set set
Operation of the inverter is stopped because no country data set is set. Once the
configuration has been completed (for instance using the installation assistant or
via a communication product), the inverter will start operation automatically.
Waiting for valid operating conditions
The conditions for charging and discharge mode are not yet met. As soon as the
conditions are met, the inverter will start charging and discharging.
Charging and discharge mode
The inverter charges or discharges the battery in current-controlled operation
(e.g. on the utility grid).
No battery voltage
Error
Inverter operation has been stopped. In addition, a distinct event message and
the corresponding event number will be displayed on the inverter user interface
or in the communication product (e.g. SMA Data Manager).
Warning
Communication with a higher-level plant controller has failed. The inverter contin-
ues to operate with restricted function (e.g. with set fallback level).
In addition, a distinct event message and the corresponding event number will be
displayed on the inverter user interface or in the communication product (e.g.
SMA Data Manager).
Communication connection is being established.
The inverter is establishing a connection to a local network (Ethernet/Wi-Fi) or is
establishing a direct connection (Ethernet/Wi-Fi) to an end device (e.g. com-
puter, tablet PC or smartphone).
A communication product requests identification of the inverter.
