New to solar. DC breaker between inverter and panels?

[bcm59]

System:
Eg4 48v 3000w inverter
Operating voltage 120 to 500
In specs max current draw 18 amps?
Eg4 48v 100a battery
Six 400w panels
VOC 37
ISC 13.8
Would a 500v 20amp 2 pole circuit breaker be the right isolation between panels and inverter?

Yes, that's fine.
It's only being used as a disconnect. So, it could even be a higher amperage if you want.

Thanks, appreciate the info.
