2.4.2 Reactive Power Regulation
The inverters are capable of operating in the following power factor range. Any
operational point, as a result of the following definitions/curves, will be reached
at maximum in 10 seconds.
PF Mode
The power factor is equal to 1, adjusted in factory, with tolerance to work from
0.98 leading (inductive) to 0.98 lagging (capacitive).
The power factor can be set via the LCD menu. For details, see “7.5.5 PF
Setting”.
Q(p) Mode
The Q(p) mode is not applicable to SG2K-S. This mode is disabled by default.
You can enable this function via the cloud server www.isolarcloud.com.hk. Then,
after any change in active power, the inverter is able to adjust the reactive
power automatically according to the following power factor curve.

The power factor curve can only be enabled when the grid voltage surpass
the activation voltage, adjustable value between 100 % and 110 % of
nominal voltage level, with pre-defined value at factory of 104 % of nominal
voltage.
