5.2.5 Setting Limited Export
Figure 20: LCS-Tool - setting Limited Export
With the Limited Export feature in connection with a
Modbus-capable energy meter, a maximum defined AC
output power can be made available at the grid-connection
point (see figure 22). The total nominal power of all
inverters connected to the Inverter Manager is taken into
account. At the grid-connection point, the inverter's
maximum output power is increased or decreased by the
amount of self-consumption.
The limitation at the grid-connection point is complied with,
while all connected loads can still be supplied with energy
from the inverters.
The maximum setpoint of the nominal PV system power can
be assigned with static or dynamic attributes:
• Assignment of static attributes:
Set the parameter Active Power (P_ref) for the active
power limitation in menu Inverter Parameter under
Protection settings > Support settings >
Immediate controls (see Section 5.2.7 “Changing of
Inverter Parameters”, page 28).
• Assignment of dynamic attributes:
In addition, the setpoint of the nominal PV system
power can be limited dynamically via I/O Box,
Modbus and direct marketer interface. If the value is set
dynamically, the parameter Active Power (P_ref) is
overwritten in the LCS-Tool. This applies to both the
regular feed-in operation and to the activated Limited
Export function. A load-dependent control is not
possible without an activated Limited Export function.
The inverters are then directly limited to the setpoint
(see figure 23).
Procedure:
1. Open the LCS-Tool.
2. Log in as an Installer.
3. Call up the menu Setup.
4. Enter the respective values under Limited Export.
5. Select [Save] to save the changes.
The parameters Meter IP-Address, Meter Modbus Port,
Meter Modbus Unit ID and the register Meter Power
Modbus are used for the configuration of the energy meter.
With zero export as a special case of Limited Export, the
feed-in operation into the utility grid can be completely
prevented. The parameter Safety Offset indicated as
percentage of nominal PV system power is a safety margin
to the maximum value of the output power set at the
grid-connection point.
This safety value is preset for safety reasons and due to
sudden load changes. Thus, a safety margin to the setpoint
is ensured. With the activation process, the setpoint is
reduced to the safety value. Thus, the feed-in power is
always less than the actual setpoint.

The parameter Meter Connection Timeout is the time in
seconds that is required to adjust the nominal PV system
power to 0 W when communication to the energy meter is
interrupted.
To acquire an overview of the current system values, open
the menu Status and select Overview (see figure 21).

Modbus control
To make this limitation permanent, set the desired
value in the Modbus register 40349.
To disconnect the inverter immediately from the utility
grid while the Limited Export function is running, set
the value "0" in the Modbus register 40348.

5.2.6 Setting the Peak Load Shaving
Function
Figure 24: LCS-Tool - Setting the Peak Load Shaving function
With the Peak Load Shaving function in combination with
the Power Analyser UMG 604-PRO from Janitza electronics
GmbH, the behavior of the Sunny Tripower Storage 60 on
the power exchange at the grid-connection point can be
optimized (see Figure 22). With the "Peak Load Shaving"
function, certain grid-exchange power outputs to which the
Sunny Tripower Storage 60 is adjusted depending on its
power and battery capacity available can be set. The
acquisition of active power at the grid-connection point is
systematically limited to a maximum value (Discharge
Setpoint/Consumption Limit). This maximum value is
given as upper limit for the grid reference power in the
LCS-Tool. The battery is discharged above this maximum
value in a controlled manner. Thus, the maximum value is
retained as long as the battery capacity allows it.
The battery is charged when the value is below the minimum
value set in the LCS-Tool (Charge Setpoint/Feed-in
Limit). In conjunction with a PV system, this value specifies
the threshold for increased self-consumption.
Procedure:
1. Open the LCS-Tool.
2. Log in as an Installer.
3. Call up the menu Setup.
4. In the menu Limited Export, the function Peak Load
Shaving is activated.
5. Under Peak Load Shaving, enter the respective
values for Discharge Setpoint/Consumption Limit
and Charge Setpoint/Feed-in Limit in kW.
6. Select [Save] to save the changes.

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.
3. Call up the menu Setup.
4. Enter the respective values under Inverter
Parameter.
5. Select [Save] to save the changes.
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.
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.
