Solar Design Review / Help

Thanks all for the responses. One response indicated I should up the wire size to the batter to maybe 4AWG. What kind of wire should I use? A lightweight battery jumper cable? Or Tray Cable wire? As far as the fuse from the charge controller to the batteries, I will up the fuse size to 50 although the charge controller only puts out 30A I believe. Remember the charge controller is receiving 24V and regulating out 12V to the batteries so in that scenario the manufacturers literature says max 540W PV's. All this is so confusing. I don't want to start a fire. Summers here are bright and hot. Even if the PV's are mounted flat, I'm concerned that in the mid summer sun, I will see high amps coming to the charge controller even though the PV's are only rated 8.35Amps open circuit.

Thanks again for your comments.
