For VDE ARN 4105, the curve cos = f(P) should refer to curve B. The set
default value is shown in curve B.
For e8001, the curve cos = f(P) should be curve A. The set default value is
shown in curve A.
For CEI 0-21, the default value of PFLockInPoint is 1.05. When Vac> 1.05Vn,
Pac> 0.2 Pn, curve cos cp = f(P) corresponds to curve B.

l please refer to ) PU Function (applicable to specific countries, local
grid requirements)
The PU function is a volt-watt response mode required by certain
national standards such as AS4777.2. This function can control the
active power of the inverter according to the grid voltage.
Selecting "Enable" means that this function is turned on and is the
default value.
Select "Disable" to deactivate the function.
