on the upper left of the picture is the combiner box, I added one in there and I use it every day and when I need to cut power to isolate.

Good quality. I used this DC breaker for the solar panels coming into my starter kit. I give it a four star because you need a pozidriv bit to tighten the wire down and not a regular philips. I had to get a special bit to tighten.

Comes with the din rail and screws. Very easy and efficient install.Utilized dc breaker for over current protection of charge controller on a diy solar/battery project.

I added this to my solar cart so I can switch it off rather than unplugging it. Easy to install as it snaps on rail.

I'm using this a breaker and disconnect for an 800 watt solar system. It works well, I've used the disconnect several times, but never under heavy load. I've never tripped the breaker, nor tested it. The only concern I have is the way the breaker locks onto the included rail. It locks well so it doesn't come off vertically, but it is still very easy to slide horizontally and will come right off the rail unless you do something to stop it. That's the reason for the 4 star rating.
