12v shut-off

Yep, my 2013 Sabre (bought in 2012) did not come with a battery disconnect from the factory.

Thanks guys, I'd love to know the reasoning behind that. I thought all RV's had CO sensors that draw power 24/7 and not conducive to long term storage without a switch.

Your correct and that's why so many new owners complain of dead batteries in their new trailer. All that grief for a $14. discount switch.

What I can't understand is the dealer not explaining this to a new owner.

Cost, pure and simple.

No they are not a standard option they put on. My last 2 did not have them and I bought my own and installed it.

My first trailer did not have one. My current one does. It's hit or miss if the manufacturer installed one or not. Probably more do NOT install them if I were to make a guess. You are then forced to just remove lead from the battery, or install your own.

I have no experience with Solar, so I cannot directly answer your question, but one thing about the Mfr provided battery disconnect. For liability reasons, it does not disconnect everything, like CO/LP detectors, breakaway switch, etc. This is the reason I installed a disconnect right in the battery compartment. That way I *know* everything is disconnected and wont come back to a dead set of batteries a month later.

So shutting off 12v from the batteries to the trailer does NOT shut off the solar panels ability to keep the batteries charged?

It shouldn't. My solar goes from the controller directly to the battery. The shutoff goes from the the battery to the trailer, So I can shut it off to the trailer and the solar keeps the battery topped off

Only a voltmeter knows for sure.

Seems like disconnecting a battery should be turning a 'connect' off.
