Hi,
I am connecting a photovoltaic system to a 3 phase load, and i am not clear with the criteria of sizing the neutral conductor of the inverter, the manufacturer manual does not say anything.
As I undestood, if the voltages diferences between phases is less than 5%, there is not a problem to connect the neutral to the system, but i am not clear the size of the conuctor, i guess it should not be less than the grounding equipment conductor, but not how bigger it should be.
I will appreciate your help with this doubt.
Thanks,
