AC wiring losses (sections)

[Fredy]

Hello

I want to simulate AC losses for a system with 4 Central inverters with a 300mm2 output cable

The minimum wiring sections that appears in PVsyst for that configuration is from 3000mm2 to 30000mm2

Is the Section in PVsyst a sum of all the sections 4invertes x 300mm2 x 3 cables per inverter (about 3600mm2)?

Or how do you choose the AC cable section in order to have an accurate simulation?

Thanks in advance

Yes, if there are several inverters, the section managed by PVsyst is indeed the sum of all individual sections of all inverters.

The minimum section proposed by the program corresponds to the section allowed (by usual practice or regulations) for the concerned current.
