I need a wiring diagram for a 24 volt off grid PV system using a Xantrex SW 4024 inverter. Is there somewhere on the Internet where I could find such a thing? I know the question is vague, but the specifics of the system don't really matter for my purposes, which are purely academic. The  supposed modules put out about 1800 watts total.

Actually, what I need is a design for a system with the Xantrex and about that much wattage from the modules.

Any help out there?

Thanks,
K.

PS - Imagine you were going to go to your County planning dept for a permit and you need a wiring diagram-what would you show them?

Do you just mean basic wiring diagram and parts? If so check out

There is a bunch of PDF's for the XW line (repalced the SW line. I am currently running a XW6048 and really like it.
