    Regarding those air compressors….

    With my Victron setup it is easy to check and I was quite shocked to see my ARB compressor draws 34A.

    Thanks Woolf! I learnt a lot and had great fun. Of course, the motivation to build a box like this needs investigation.

    Is it "better" to purchase a National Luna box with everything? Or "black box" units like Hcdp, Wrnd or National Luna? It's probably cheaper, smaller, neater. I don't know. But this is very satisfying!

    Wow, that's a large draw! It makes sense to rather run it off an idling crank battery (alternator).

    Which ARB model is that?

    Yes, there's no doubt about its safety. Just a heads-up when considering large draw items.

    Mine draws about the same (from the manual), which is why I have it on a separate 50A circuit... And I run it off my aux battery

    Leon, as promised, a pic of my setup, going the "DB board" route as opposed to a box. Yes, it is less portable, but seeing as I may only be camping 3-4 times per year, it is "reasonably portable" if I wanted to unbolt it and use it for loadshedding. The solar panels might be awkward (but not impossible) to set up in my garden; or I can purchase a 220V LiFePO4 charger.

    Next to the switchbox is the blue BH connector for the solar panels. Underneath the switchbox (red plastic square) are my strip fuses, just as extra protection to the DC circuit breakers which are housed in the switch box. Copper lugs (plumber's copper pipe) can be seen to the right of the fuse box (positive) and to the left above the black sockets (negative) to which I attach my compressor. Sockets are 1 x dual USB and two cigarette lighter sockets. My LED lights run off one of the cigarette lighter sockets. The fridge runs off a BH connector mounted on the back of the DB board, just above the left copper lug. Those are the two lonely bolts poking through.

    Circuit breakers inside the switchbox, left - right are: Load, PV input, Battery and Compressor. Battery can be seen held down by turnbuckles at the bottom, and the compressor sits conveniently positioned on the wooden "bridge". I have a small (300W) inverter that I will need to use to charge my radio (has no car charger, only 220V) , which I will mount most probably top left of the board.

    Seeing as everything is mounted up against the bulkhead, it takes up more space than a box, but is not too much in the way. I'm not a great craftsman, so everything is functional rather than "neat". Also, cabling is reasonably accessible (on the back) to troubleshoot.

    FWIW...

    Thanks for the pics Rob. That setup looks perfectly functional, and obviously serves your needs. I like the vertical stack. I think it takes up less space than a box, and everything is visible. I particularly like your very practical compressor lugs . Well done!

    Thanks, Leon. Wherever possible I hate cutting cables; the lugs make it easy to use the supplied crocodile clips on the compressor.

    The battery box is fully built, and now sports a cigar plug, a hella plug and a dual USB. These appear to be de rigueur for the modern, well-dressed battery box.

    As a loadshed-buster, the box is a screaming success:

    That means I can still plug in my Dell XPS 13 (60 W while charging and working), and even the Engel (40W) in an emergency, without coming close to hurting the 400W Phoenix.

    Very, very nice and neat Leon. Looks like the work of a true craftsman.

    I'm curious as to what adapter you are using for the schuko socket on your inverter? They're quite hard to find.

    I have one of these which is working well so far:

    Hi Stuart, and thanks for the kind words. It was a nice project to learn a bit more about the mysteries of electricity!

    I made up a little cheapy lead in the interim, with a male Schuko from ACDC.

    I must say, the standard of electrical fittings is quite low generally. I have yet to find a shop that provides a wide range of quality fittings in Cape Town, and it's very frustrating. I'm going to build a portable box for the inverter, and will post here what I come up with.

    I used one of these SA sockets. It splits in 2 halves. One on either side of the front plate. They are sold by AC/DC. No need then for any adaptor.

    I haven’t seen them in a hardware store for a looong time. They usually come as moulded plugs with the lead.

    I suspect they may even be illegal to sell.
