Building System, need input

[Lafnbug]

Some of this I have, much I am almost ready to order.

(4) Renogy 150w panels for 600w total solar
https://www.amazon.com/gp/product/B...e_10?ie=UTF8&psc=1&smid=A05654602L3XUQ70M87BV

(2) Branch connectors
 https://www.amazon.com/gp/product/B00W85TGDW/ref=ox_sc_act_title_8?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

(2) 30a inline fuses
https://www.amazon.com/gp/product/B019YP0KSS/ref=ox_sc_act_title_5?ie=UTF8&psc=1&smid=A2TN19FHI2Z5KL

(2) 10awg  MC4 from panels to CC's
https://www.amazon.com/gp/product/B...ct_title_13?ie=UTF8&psc=1&smid=A1Z4QPXV0KM1LQ

(1) Blue Sky 2000e

(1) Blue Sky 3000i - I want redundancy. 2 panels in parallel to each controller

(2) 10AWG from CC's to Batteries (4 GC's)
https://www.amazon.com/gp/product/B...ct_title_14?ie=UTF8&psc=1&smid=A2D22KZJD14Y8Y

(1) Blue Sea 5026 fuse panel
https://www.amazon.com/gp/product/B01C7A8PT8/ref=ox_sc_act_title_15?ie=UTF8&psc=1&smid=AIETQIZIYBNIX

1. Can someone recommend fuses to use between the batteries and Charge Controllers?

2. What wiring should I use to run my circuits for:
a. 12v fridge: undetermined
b. lights (3) of these: https://www.amazon.com/gp/product/B00CZCY5SE/ref=ox_sc_act_title_12?ie=UTF8&psc=1&smid=ATVPDKIKX0DER
c. this: https://www.amazon.com/gp/product/B01AYOSD50/ref=ox_sc_act_title_11?ie=UTF8&psc=1&smid=ATVPDKIKX0DER
I'm guessing about 3-4 amps each for the fans:
d.  Fan 1: https://www.amazon.com/gp/product/B003ZOF09Y/ref=ox_sc_act_title_7?ie=UTF8&psc=1&smid=ATVPDKIKX0DER
e. Fan 2: https://www.amazon.com/gp/product/B0000AY2Z6/ref=ox_sc_act_title_3?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

3. What else am I missing, besides a fat wallet?

I will be adding other items to this system later, but wanted to get a basic usable system for now. One thing I'd like to find is a good ciggy/USB combo for 4amps to recharge larger devices. This is my first system; any comments welcome!

And the best method for getting the solar cables thru the roof?

are you planning on fuses each panel? on the roof? if so I would use waterproof fuse holders and mount them under the panel up off the roof. some people just drill holes in the roof feed the cables through and use the self leveling sealant to seal them. I prefer a terminal box, then you can also combine all your wires and only send 2 down. highdesertranger

I used Blue Seas Cable Clam to pass four 10ga wires through the roof. I'm happy with it, but didn't feel that the tightening of the top clam really compressed the rubber puck much, if at all...and I read that was part of how it tightens to cables for waterproofness. 

But it was a tight fit anyway, had to use some WD40 to make pushing them through easier, and it didn't let any rain in over past week. Still, once the installation is complete, I'll probably hit it with some caulking...

HDR: Yes, these are roof mounted. I was planning on running 2 panels each, in parallel, to each charge controller. Basically two equal, separate systems. Do I need to fuse each panel, or just the main coming into the controller?

BradKW: Those look nice. One thing that concerns me is I'll be coming through a thin aluminum roof. I'm starting to think the terminal box that HDR mentioned may be preferable, as it will spread the load across a bigger area of the thin metal. IIRC, Matlock did this on his identical vehicle.

I have never fused a panel, but I have only run 12v panels. highdesertranger

My controller (Morningstar TS 45) recommended a 60 amp fuse in line with the solar panels.  Makes an easy way to disconnect the panels for maintenance.
