life passes by too quickly to not live in freedom
So maybe it’s that amazon doesn’t search well but I can’t find what I’m looking for. My own unfamiliarity may be a part but I’m not an idiot.
Backstory: had sudden sun today with batteries at 12.0-12.1ish. Blew 20A fuse for my 2S2P @400W setup. (I am aware fuse should have been 30A; neglected at upgrade, cables are 8ga)
So I got to thinking I should actually just get a combiner box to accommodate the max I’ll likely ever do for this RV trailer which is 3S3P (I have the panels for 3S2P right now, just only running 2S2P)
My issue is if I blew a 20A fuse, that suggests that the boxes like the ecoworthy come with 10A breakers. I’m assuming they can be replaced but why not just buy it loaded with 15A but I can’t find that option.
Second, the combiner boxes I’m seeing appear to only be made with MC4 plugs on the box, and for exterior use - not a provision for interior clamp fittings to connect the cable inside the box mounted inside. I intend to pass two or three pairs inside and simply connect them in the box like a breaker panel. That’s all I need, it feels simple and neat and clean but I’m not seeing these. There’s some midnite boxes that seem ok too but, again, this is a lot of why I’ve been hanging here, to get to know what I know I don’t know.
Am I reinventing the wheel here? Or should I just buy a small empty box and populate it how I want?
