Reactive power control, Reactive standard curve cos φ = f(P)
For VDE ARN 4105, curve cos φ = f(P) should refer to curve A. Default values of setting are
as shown in curve A.
For E 8001, curve cos φ = f(P) should refer to curve B. Default values of setting are as
shown in curve B.

g) RS485 CommAddr
If “enable” is selected, the inverter will communicate with the computer,
through which the operating status of the inverter can be monitored. When
multiple inverters are monitored by one computer, RS485 communication
addresses of different inverters need to be set.

e) Grid Protection
Usually end user do not need to set the grid Protection. All default value have
been set before leaving factory according to safety rules.
If reset is needed, any changes should be made according to the requirements of
local grid.
h) Mppt Scan Mode
There are four modes to be selected. “ ”, “ ”, “ ”, “off low freq scan mid freq scan high
freq scan”. It shows the frequence of PV panel scan.
If “low freq scan” is selected, the inverter will scan the PV panel by low
frequence.
