Solar Panel and Wind Turbine Power in the Same Cable

[SolarWindBoy]

Hi,

At home, I have both a 15kW AC wind turbine and a 1000V solar array in my garden. To decrease the cable losses between the generators and the inverters I am looking at installing a higher gauge wire.

I had spotted that it was cheaper to buy a 5-core cable as opposed to a 2-core and 3-core cable. So I wanted to check if it was safe/legal to use a 5-core cable.

In NEC 690.31B I saw it says that they should be separated by a partition. Would the insulation around the conductors be suitable for this?

Or should it be 2 separate cables installed in 2 separate conduits?

Thank you for any help that can be offered with this.

I can't answer this for sure, but because the wind turbine is an AC current and solar DC, I would expect this would not work as you stated. There is a lot of power going through both those cables.
