This is what I use for 110 and solar in. You can just use a regular heavy extension cord.

They are available in white, but the black seems to look better as the white gets dirty quickly.

This has the wrong end on it doesn't it?? I was looking for the female end like a plug at the house. You would need a double female ended extension cord to use this. Never seen on of those. I have to be wrong here...right?
