Volt-Watt Response Curve (“AU” for example)
12.3.2 Volt-watt Response for Battery Charging
When the power from the grid is required to charge the energy storage system,
the import power from the grid varies in response to the grid voltages. The
response curve is defined by the voltage reference values and the
corresponding power consumption from the grid for charging energy storage.
The Volt-watt response mode for battery charging
is enabled by default.
Set four grid voltages and the corresponding
power consumption upper limits (in % to the
maximum input power 3000 W).
