User Manual 2 Product Description
17
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 that not exceeds
10 % of the maximum active power per minute.
2.3.5 Reactive Power Regulation
The inverter is capable of operating in the following reactive power control
modes for the purpose of providing support to the grid. The reactive power
regulation modes for the country “DE” can be set via the LCD in commissioning.
For the other countries, they can only be set via iSolarCloud App or iSolarCloud
server.
Fixed Power Factor Mode (PF)
The PF mode controls the active power factor of the inverter’s output according
to a set-point set via the LCD. The PF ranges from 0.8 leading (+) to 0.8 lagging
(-), with the default value of +1.0.
Voltage Related Control Mode Q(U)
The voltage related control mode Q(U) controls the reactive power output as a
function of the grid voltage.
