Solar panels - Part 2

I just realized, I never did get around to showing the rest of my solar panel installation!

Here is a photo showing the cable coming in from the panels, going to the cheapy MPPT charge controller from China on ebay and the cable running out, down to the battery bank.

Both solar panels have in-line fuses outside in weatherproof holders and the controller has a fuse between it and the batteries, so it's all well protected. It's almost all 8 gauge wire, except the ends at the charge controller, the solar panel connectors and the fuse holders. Those are all 10 gauge but such short length, they can carry plenty of amps like the 8 gauge, should I add more panels later. 10 gauge might have been all I needed, but it's better to oversize the wiring in case of expansion, rather than having to rip it all out and redo it later.

I have a 3 outlet strip plugged in to a 12v outlet up front I added. I'm not using the power output hookups of the charge controller but some people might wish to, if they do this kind of setup.
