Cut off switch with solar panels

[4x4ord]

I bought 4x 100 watt solar panels and a Renogy Rover MPPT charge controller. The Rover manual states: NEVER connect the solar panel array to the controller without a battery. Battery must be
connected first.

So I guess I have to remember to remove the batteries I need to disconnect the panels first. I find this interesting because my father has been pulling his batteries out of his 5ver for winter storage for years and I'm sure he doesn't disconnect his solar panel to controller. Maybe the wattage of his panels isn't enough to fry the controler. I think this sounds like an accident waiting to happen. At some point someone will disconnect the battery to replace it or clean the posts and not know to disconnect the controller first. I guess it would help some to install a switch on the positive wire from panels to controller?


Edit: I was wrong. He pulls a fuse on the front of his controller when he removes his batteries.

Maybe he's under cover..?

That’s what most installers do. Might be a good idea to post a label by the battery terminals reminding techs to turn of solar switch -and where it is located- if you’re anticipating someone other than yourself working on it.

I turn my solar off before putting the coach in for repairs just in case.
