Hi Joel,
For some controllers running without the battery connected may let out the magic blue smoke.

No switch. My RV runs 24/365 on solar. And with 510 watts you should not have an issue. Off is fine too.
Always cut power from panels before you disconnect controller from battery.
What's the danger....overloading the controller? I have a fused breaker before and after the controller and shut the one off between controller and batteries occasionally so I can measure true panel output without the battery influence.
I used the cutoff switch while replacing my batteries last weekend, and suddenly heard that rising pitch whine that usually means smoke escape is imminent. I forgot to shutdown the solar first. I think I got lucky. Everything appears to be working.
