Lithium Battery

RockDr896,
So you do not have a separate solar disconnect switch? Our 385fl came with a main battery disconnect and a separate solar disconnect. When I stored my unit in Sept with a 86% SOC on my 300ah lithium, I pulled it out 2 weeks ago and it was at 85% SOC. Do you have lead acid batteries?
I learned my lesson in 2023, when I bought the rig. I went round and round with Alliance, because the NEC requires a complete disconnect between the panels and the rest of the system. Alliance told me, the RV industry did not adopt that part of the electrical code...LOL. I installed my own and have not had a problem since. It' also nice, because it isolates the panels when tracing electrical issues. Solar panels cannot be shut off...all you can do is isolate them. I guess maybe they have reconsidered their stance on this $89 fix...good to hear. I have three 100Ah lithium batteries

and since the trailer is not truly grounded and grounded to the frame, the possibility of a hot skin issue is real. Maybe rare, but possible. Shortly after that, they also did a recall at the roof penetration area. They had used wire nuts at that point. Perhaps, they listened and quickly started correcting the issues...a feather in their cap for listening and taking action!!

Shore power ground is not connected to the frame? 😮😮😮😮 I didn't know that. I'm shocked.😉
I am not sure about that, but I would guess you are grounded on shore power. Smarter people here can answer that. While boone docking or traveling down the road, you would be grounded to the frame.

I think you are grounded to the frame with DC, even on shore power....again...smarter people can chime in on this as well.

I bought my rig in Dec and had to fight the additional issue of parking a solar package in a dark warehouse. The batteries were drained, because of solar panels not having a breaker to shut them off....so batteries were drained....and I could not wake them up. So I had backed up and married to my 5th wheel hook up, but then jacks would not work. So luckily, I released my 5th wheel jaws and turned the truck around. Hooked my jumper cables to my batteries and that woke them up on a 28 degree day and charged them enough. I am not recommending this approach, but I am saying I survived it, nothing caught fire, nothing was damaged, and the trip was not delayed. I am offering this, as a caveman's approach...hell, I have insurance...LOL...did someone say "Camp Fire talk"?
Same question as 2 Allies. We bought our 32RLS 9 Sep and it has battery disconnect and solar disconnect in forward storage area. No, you can not turn the solar panels off. You can just stop them producing any useful power.
