FW500 DC parts?

Postby dan100acrewood on Sun Jul 05, 2009 12:01 pm

First my system is working!! Now I'm looking over the extra parts; I have the piece of metal about 2 by 3 inches with holes in it. How should I have used it?

It sounds like a DC buss. It is typically used to connect the DC conductors together -- battery cables to charge controller outputs to inverter inputs.

If you have a small enough system, one approach is putting too many cables together under a single bolt. Look at the ends of your larger conductors and see how many other larger conductors (lugs, whatever) are under the same bolt or screw. That's where you should have used the DC buss you have leftover.

might be nice if there were some directions in the documentation. So far I've found good places for all the wires (I hope!)
Thanks

Dan,

Some of what is missing is just standard electrician stuff. Like, knowing which direction to wrap a wire under a screw, or how many wires can be put under a bolt.

Did you manage to find a use for that plate? Determine that you don't need it because you don't have enough connectors in need of connecting?

Julie,

I think my system is still pretty simple. I have a few multiple connections, but nothing I'm worried about. Else I would have asked sooner. I have a big binder full of documentation and nothing about that buss. Could I be the first newbie to solar and outback to have missed it?

Dan,

I dunno -- not putting more wires under a bolt or into a terminal block than rated is pretty much Electrician 101 stuff. I don't want to say you have to get rid of the places where you have multiple lugs under a bolt by replacing them with a buss plate, but it wouldn't hurt.

I am in the process of installing our flexware 500 and the DC side lacks good installation instructions. I'm very impressed with the overall design of the equipment and instructions in general but the DC side doesn't have any wiring diagrams or much for instructions. I even looked on their wedsite to see if we lost something and you can see there is a gap in their documentation.
