Solar panel disconnect switch.
What do you guy’s recommend for a Solar panel disconnect switch? I'm thinking that I don't want my battery’s always connected to the solar panel while the trailer is in storage. I pull the main bat...

Blue Sea makes a marine grade switched circuit breaker which is what I use. I can mechanically switch it off or it trips with a short in the circuit. I used it so that I can kill from the panels as they are still "hot" current even after the sun has set.
With most charge controllers if the positive and ground wires are switched even for a second it destroys the controller. I wanted to be able to kill power from the panels at the C-box. Not current into the controller then no current out to the batteries. I have a separate fuse on the output from the controller to the batteries.
A good charge controller will function like a trickle charger to keep your batteries topped off and maximize their life. Discharged batteries freeze at higher temperatures and will deteriorate faster so keep the controller connected.
