… why it is that I need to move the batteries. They are blocking up the front door. And if I’m going to start some kind of serious work inside, I need the front door off so that I can bring messy stuff in that way rather than in through my little room.

Today, I put a row of breeze blocks down on the concrete base that I laid yesterday. I can’t build it right up as just right now I don’t know how high the suspended floor is going to be. But tomorrow I’ll be putting a layer of 40mm polystyrene on the base and around the sides, and dropping 10 batteries (thats 920 amp-hours in total) in there.

I’ve also started building the control panel as you can see. There are three charge controllers on there right now. From right to left, we have the charge controller for the 2nd bank of solar panels (the one for the first bank is currently nailed to the front door and will be moved onto the control panel in early course), then in the centre is the charge controller for the wind turbine, and on the left is the charge controller for the overload.

In case you don’t know, when the batteries are fully-charged the charge controllers shut down the charging circuit. And that’s a waste of energy. So what I’m doing is having an overload controller that will divert the surplus current into a “dump load” – in this case a 12 volt water heater element. So that way I’ll have plenty of hot water.

There’s also a bus bar or two on there. These are for connecting loads of heavy duty wires and cables together. Bus bars range from sophisticated professional jobs down to flattened copper pipe and self-tapping screws, but for many years now I’ve been developing the “ring terminal onto long bolt with butterfly nut” and it works just fine, so there’s no reason to change.

There will be a few other things on there too, like a mains inverter, a couple of clocks, some circuit breakers, a fuse box and all that kind of thing. Here is one I made earlier, but that has undergone considerable … er … modification since then.

And what do you think about the wallpaper in the house? The house as you know is built of stone and they plastered over it on the inside, and then put up some wallpaper of … er … stone. Why didn’t they just knock the plaster off?

Meanwhile, back at the ranch, Claude’s son came round this afternoon. he’d been rummaging around in one of his dad’s many sheds and came across a trailer board.

Well, a sort-of trailer board. The lenses on the lights were smashed and all the cable was missing but I cleaned it up, cleaned all the contacts and rewired it, and now there is in theory a working trailer board. I say “in theory” because there are no bulbs either but I have a 12-volt piazzo tester and when I connected it up to the contacts for the bulbs it did what it was supposed to do at the time it was supposed to do it.

So all Pascal needs to do now is to buy some lenses (they are “standard trailer – small” and some bulbs, attach it properly to the rear of the caravan, and there you are.

I checked and adjusted the brakes on the caravan too and during the course of the evening I learnt that
1) The caravan is over 40 years old
2) Pascal has never towed a trailer (or indeed anything, for that matter) before.
All I can say is “good luck” to him, taking that over the “Cote de Maille” between Puy-en-Velay and Montelimar at night.
