Is this on a stock trailer or something added after delivery? I suspect it could be a solar discon
Thank you both for replying.Need more info. That does not look like a factory install. Is this a used RV? Can you see where the wires go? What are they attached to?
We have a 2024 RL310 as well and it is in fact equipped with 2 disconnects from the factory. One is for the 12 v side and the other is in fact a solar disconnect.On a related note... I have never seen a third position for a disconnect switch ("ON", "OFF", "ACTUATOR OUT")
It's for removing the knob to prevent someone from actuating the disconnect.
Thanks for following up on this. Nice to get one right once in a while .I got word from Alliance today as to the purpose of the two disconnects.
Those that said "Solor Disconnect" are correct
The left (red) one is a battery disconnect.
The right (black) one disconnects the solar PV panels from the charge controller.
Because they offer a "Super Solar Plus" upgrade with 3x 320w panels, which when wired in series can product 99 Vmpp and 120.9 Voc...with maximum of 960watts.Why would Alliance add the cost to all of their units for the very few who would ever need to worry about voltage? We often forget that most folks just buy the RV and use it without spending thousands more on it with all of our fancy gadgetry. Plus, it is really easy for you to change yourself after the fact if you prefer a breaker.
Do they deliver it wired in series? There is still not going to be a lot of current moving through that. The options list doesn't indicate which equipment is specifically included, but I would be surprised if they step down from 48v. No matter how you slice voltage and current, it is still only 960w of power. I am not sure what the breaker will buy you from a disconnection standpoint over a switch. And the controller itself should have over-voltage protection. I could definitely be missing something, but does OP have this upgrade in place? I am sure there are way more units delivered without this option than with this option based on checking inventories.Because they offer a "Super Solar Plus" upgrade with 3x 320w panels, which when wired in series can product 99 Vmpp and 120.9 Voc...with maximum of 960watts.
The OP only has the standard 320W panel.Do they deliver it wired in series? There is still not going to be a lot of current moving through that.

At the charge controller on the panel side. I just cut into the lines, put on new ends and tied back into the controller. Now I don't have to climb on the roof or remove the stranded connection at the controller. It totally isolates the solar panel system, so when chasing an electrical issue, it can be eliminated easier. Attached is a drawing I made when talking to Alliance about my issue.Where did you mount that? At the controller? In a box on the roof?
There is another connection point on my 370FB that can be accessed via a light can above the sink area. So technically, a person could hang a box "inside" the trailer without mounting another box and cutting the roof. Good luck getting that through the interior decorating dept!Thanks for the reply. I'm considering adding a switch or breaker, but I wasn't sure if I should put it there, or on the roof so it protects the cables as well.
Love your labels.What I did is what Alliance COULD include at very little cost.
