At most I'll have three 365W panels in series. The lsc of each panel is 11.07A. Do I need a breaker between the panels and the inverter, and if so, could you please recommend one if possible. Thanks.
Those baby boxes are pretty pricey for what they are. If you can get some DIN Rail you can get creative and avoid needing the box.I have a Midnight Solar 20A single pole DC breaker, and a baby box in my amazon cart. Do I really need the box?
I have added Din Rail to these Square D boxes for those type of breakers.

Would a piece of this work? Or this box, it has a piece if DIN rail in it. The box is only like $7.Those baby boxes are pretty pricey for what they are. If you can get some DIN Rail you can get creative and avoid needing the box.
That's the Din rail. You can simply screw it to the wall alongside the inverter. Kind of rough looking application but it will work to hold the breaker but not the most substantial support.Would a piece of this work?

Noooo... that ANL fuse is only rated at 32V ????An ANL fuse on the positive is also a good idea.

It's for low voltage battery to inverter not PV to inverter.
you do not, the breaker is no good for solar, you would need breakers if you had 3 or more strings combined in parallelAt most I'll have three 365W panels in series. The lsc of each panel is 11.07A.

This is because a solar panel, or string of panels will not ever put out more current than it is rated at. Even two panels, or strings in parallel won't put out enough current to damage the wiring. Only when you get three panels or strings in parallel will you get more current than the wiring is rated to handle. This is code. Therefore, a disconnect, switch, CB or whatever is purely for convenience.Some say the fuse is optional in your configuration for various reasons,
Any suggestions for a 60a version?

Midnite Solar has a 300 Vdc version also.Something like this
IMO DC Isolator 16A 2 Pole 800V (Single String)
The voltage matters for a DC switch, not just the amperage. Very useful to be able to switch the solar off, you can't turn off the sun.

We've almost come full circle. This is the one I originally looked at. According to my math, this would be the correct breaker.Midnite Solar has a 300 Vdc version also.
