Settings for peak load shaving
Additional electricity costs can be saved if you reduce your power consumption from the utility grid by intelligently adjusting your battery storage system. An increased energy demand at certain times of day (e.g. in the morning or in the evening) leads to so-called load peaks, which can have you classified into a higher tariff category. Thus, the battery-storage system allows you to capture, i.e. "shave" these load peaks with stored electric current. Adhere to the following information for the configuration in the process:
Setting | Explanation |
|---|---|
Peak load shaving | By activating the operating mode "Peak load shaving", you can specify the maximum power supply from the utility grid as well as a limiting value for the portion of the total storage capacity of the battery system for the peak load shaving. |
Limiting value for peak shaving | The threshold specifies the maximum power that may be drawn from the utility grid. When this power is exceeded, the energy required is drawn from the battery. As soon as the battery is discharged, the corresponding load can no longer be operated. In order to be able to operate a load despite the battery's insufficient state of charge, the purchased energy limit can be increased temporarily; see 'Increase threshold adaptively'. In this case, the load is operated with electric current additionally drawn from the utility grid, which needs to be compensated for as well. |
Threshold for switching operating modes (multiuse) | By entering a SOC (state of charge of the battery) limit, the total storage capacity of the battery system can be divided.
|
Adaptively increase threshold | When activated, the threshold is automatically adjusted to the new maximum value if the grid-supply limit could not be met, e.g. due to insufficient battery charge. |
