Input values for Peak Load Shaving
The input value for Discharge Setpoint/
Consumption Limit is interpreted by the Inverter
Manager as a positive value and the one for Charge
Setpoint/Feed-in Limit as a negative value. If the
Inverter Manager, for example, has to limit the grid
reference power to +50 kW and charge the battery
below a grid reference power of +10 kW, the value
50 must be entered for Discharge Setpoint/
Consumption Limit and the value -10 for Charge
Setpoint/Feed-in Limit.
If the value for Discharge Setpoint/Consumption
Limit and the value for Charge Setpoint/Feed-in
Limit is set to 0, this corresponds to the classical
increased self-consumption of PV power without the
shaving of peak loads.
5.2.7 Changing of Inverter
Parameters
Figure 25: LCS-Tool - changing of inverter parameters
All inverter parameter are Grid Guard protected and
require the Grid Guard code for changes. To change the
inverter settings, use your SMA Grid Guard code under the
user group Installer (see section 5.2.2, page 21).
Procedure:
1. Open the LCS-Tool.
2. Log in as an Installer.

FNN note
In Germany, according to FNN note "Connecting
and operating storage units in low voltage networks"
(October 2016), systems eligible under the FIT
scheme in accordance with EEG and KWKG are not
allowed to feed energy from storage units into the
utility grid. To ensure this, the input value for
Discharge Setpoint/Consumption Limit is not
allowed to be negative.
3. Call up the menu Setup.
4. Enter the respective values under Inverter
Parameter.
5. Select [Save] to save the changes.
