Are you also installing an inverter to run the "house" electric? If so, a 2000w inverter will need bigger cable to run properly than the solar converter needs to supply the batteries. I have the 6awg running from the roof feed to the converter, about two feet of #4 cable from the controller to the connection posts on the back of the 2000w inverter, then #0 cable from the inverter to the batteries. Since my batteries are four 6v, wired in series two make two "big" 12v batteries, then in parallel to combine them, all of the cable connecting the batteries is #0. I used red and black for the pos and negs, but I ordered yellow for the two jumpers that join two 6v into a big 12v.

I already have a 1000w inverter for the residential fridge.
This is pretty much the only reason I'm putting in the solar.

We're spoiled now, having 120v available at any outlet, whenever needed. When I traded my previous trailer, I was disappointed that the dealer wouldn't give me any money for my solar system, and preferred that I completely remove it. Now I'm glad that I did, as it's all installing nicely in the new North Point!

Klassic - Are you installing a fuse between the panels and the controller? I have a disconnect switch, but the more I'm reading, it should also be fused. (I didn't have that on my previous installation.)

I looked at in-line cartridge fuses that would connect at the MC4 connections on the roof, but I couldn't find any with a UL rating, and I saw some bad reviews on them failing (melting). Instead, I'm thinking of an AFN/AHN style 30A fuse mounted before the disconnect switch, in the basement. These fuses and the fuse holders are readily available on-line, or at any of the retail places that sell the components of the high-power "boom" car audio systems. (I think that Best Buy has them.)

I am using one of those dc breakers in my picture. This way it is on a breaker and I can use the breaker for disconnect too.
I suppose it would make more sense to have the line fused closer to the panel incase the wire shorts, but oh well...I'll risk it.

Finally installed.
Not real world tested yet, but this morning at 7 I unplugged the shore power with the residential fridge running, whatever parasitic draws and the roof fan running.
I came home 12 hours later to a completely full battery and everything still running.

It is a GREAT feeling when it all comes together and works great. Now for the over night test with no shore power. Get some self leveling Dicore and cover all your mounts for added protection

I went to my dealer to get some self leveling sealant, I needed beige...they had tons. Brought them to the counter and noticed the bottom said White.
All mislabeled.
Do you think they cared? I'm still waiting, two weeks. Maybe this Saturday.

I put little squares of Eternabond under each mount before screwing. Should be good until I get the caulk.
