For VDE ARN 4105, curve cos φ = f(P) should refer to curve A. default value of setting is as
shown in curve A.
For E 8001, curve cos φ = f(P) should refer to curve B. default value of setting is as shown in
curve B.
For CEI 0-21, default value of PFLockInPoint is 1.05, when Vac > 1.05Vn, and Pac> 0.2 Pn,
curve cos
φ = f(P) should refer to curve C. Default value of PFLockOutPoint is 0.98, when Vac
< 0.98 Vn, cos φ = f(P) will exit curve C.

d-1-3) Grid
The enduser do not need to set the grid parameters. All default value has set on
factory according to safety rules.
If need to reset, any changes should according to the requirement of local grid.

d-1-4) Export control
This function allows the inverter able to control energy.There are user value and
factory value. The factory value is default which can not be charged by user. The
user value setting by installer must be less than the factory value.
Choose”Disable” means the function will be shut off.
