Will i need to add a cutoff switch for when I am on Shore power to protect the Charge controller?

No, the charge controller and converter will play along nice with each other. Sometimes, depending on variables, the device that delivers the most power will do most of the heavy lifting and the other charger will sulk along in a corner, taking a time-out. Sometimes, both chargers will be additive delivering more charge than either single device.

I'd suggest to use a manual circuit breaker between the solar panels and the charger. It is a handy way to turn off the solar charge if you wish to do some work on the system. I use this CB manual breaker. I think I've interrupted power just a couple of times to do some battery upgrades.
