5.2.8 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.
The Peak Load Shaving function cannot be used in parallel
with the Time of Use function. Which function is active,
Installation manual
Procedure:
1. Open the LCS-Tool.
2. Log in as an Installer.
3. Call up the menu Setup.
4. In the menu Power Management enable the function
Peak Load Shaving. Otherwise, the Time of Use
function could be used.
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.
