The following figure shows the under-frequency response.
Between the Start value and the End value, all adjustable power generation
systems shall reduce (for frequency increase) or increase (for frequency
decrease) the active power Pm generated instantaneously.

Fig. 3-5 Active Power Response at Under-frequency
If the grid frequency increases and is between 49.80 Hz and 50.20 Hz, the
active power supplied to the grid will recover with a gradient not exceeding 10 %
of the maximum active power per minute.
For the country Italy, the under-frequency response is described in “11.2.5
Frq-watt Response”.
3.2.5 Reactive Power Regulation
The inverter is capable of operating in reactive power regulation modes for the
purpose of providing support to the grid.
For the country Italy, the Q(U) mode can only be set via the iSolarCloud App or
the iSolarCloud server. The other modes can be set via the LCD menu.
For the countries except Italy, the Q(U) and Q(P) modes can only be set via the
iSolarCloud App or the iSolarCloud server. The other modes can be set via the
LCD menu.
