f-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.

f-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 changed by user. The
user value setting by installer must be less than the factory value.
Choose”Disable” means the function will be shut off.
The meaning of the set number is the max. output power allowed. If the user do
not want feed any power into grid, then please set it to 0.
