2024 tab 320 css lithium upgrade and solar upgrade, please help

Sledhead1 · October 30

I found a new 24 320 css with the convenience package. It didn't have the lithium upgrade package or the black canyon. So i want to add them my self. I bought the second bb battery and a multiplus 2000 but there is no room to install it?? Where did they put them in the css models? I also orders a sun flare 180w panel but its way different than the factory panel on the front. Its 65"x 45" approx and the factory is only 35"x45" with the wires under the panel. How is it a 180w panel but so much smaller. The one i got has surface mount mc4 connectors. What is the best way to get them into the wheel well area. Im guess i wont be able to run them into the same controller now. I bought a 100/30 but i dont know what the factory panel is or its specs. Plus i have a 220w portable panel i was going to wire into another 100/30. It looks like ill end up with 3 controllers now? Does anyone have a picture of the multiplus in a 320css. The only place i can see is maybe behind the factory fuse panel? I though i was just going to copy the factory and make a 320 css black canyon with lithium upgrade but this might not be possible.

I installed the 180w SunFlare panel on the front of our 2018 CSS two months ago. (I'll post pictures once I take them.) The panel starts about 3 inches above the front window and goes within a few inches of the fan opening. The wires run through a hole I drilled into the bathroom vent cap, through the A/C space, behind the TV, down to the controller under the bench. I had already moved my batteries inside, sacrificing the lower front left cabinet. That probably was a mistake; I think they should be in the passenger bench, behind that side's Alde radiators.

Oh dear, my memory: it's going.

I went out to take pictures and discovered that actually had I drilled a hole in the roof and installed something like this.

The panel looks like this:

That better than i found. The battery wiring is very helpful, but the mutiplus cant go there in a css, its shorter inside and my ac is right by the batteries. The only possible, and im not sure it is, is behind the wfco. Every other spot is full.

This is the same panel i got for the rear of mine. Its different than the factory panel as they go in the roof under the panel I found out. And sun flare does not sell the panel to the public, its a 180w mono crystalline panel. That gland looks like the right part for the job for sure. It kind of sucks because of the different type of panels i have to use 2 mppt controllers.

Although I had problems trying to buy from Sunflare, I was able to purchase their 310W panel through nuCamp. I went through my dealer (Miller in PA) and had it drop shipped to my house. Having the connections under the panel is a cleaner installation.

Huge improvement over the 100W factory installed panel ...

I believe the factory fit for the Lithium upgrade on the CS-S has one battery turned 90 degrees and located forward of the passenger wheel well, the second battery located more or less where it is in the single battery configuration, but, shifted aft to accommodate the first battery and the multiplus wedged in between the Air8 and the second battery. It's a tight fit.

Oh, i would like to see pictures of that. im guessing its on its side then ?

This is the thread that Yanni in an earlier comment brought some photos from. Lots of good information in the rest of the thread:

When NuCamp brings out a "new version" or design in a trailer, there can be many running changes in trailers that were built only a few days or weeks apart. And, probably even more if the trailers are a year apart. So, some of the work you might want to do will have to be "creative" on your part to make things fit, etc.

Lots of owners have done various mods like you want to do, there will be plenty of help.

Howdy, Stranger!
