Wednesday 29th February 2012 – I’VE GONE …

… onto summer hours!

Yes, already! It’s now light enough to be still working outside at 19:00 and so that’s what I’m doing.

And the computing activities that I need to do, well I’m doing those from 10:00 until 12:00.

So with an early night after my dithering about, I had an early morning as well, just for a change. And on went the coffee pot again because if anything it was even nicer today than yesterday.

So much so, in fact, that I ran the electric heater up here. Not because I needed to, but because it was a shame to waste the energy.

One of the things that I needed to do was to print off about 50 pages of stuff that I need to complete. And I think that I’m having printer issues. The black ink didn’t work at all and in the end I put a new cartridge in.

That worked fine for a few pages and then we were back to the missing lines and dirty heads again. I cleaned the heads, and that worked fine for a while and then we were back in the missing lines and dirty heads.

I don’t know why that is. Printers never seem to last very long with me.

This afternoon I had a pile of fun.

I’ve had a few parcels delivered these last couple of days, and one of them contained the half-a-dozen 12 volt DC hour meters similar to the 230 volt ones that I bought to run with the mains inverters.

control panel solar energy wind turbine timer overcharge meter les guis virlet puy de dome franceThe purpose of these 12-volt hour meters is to wire them into the solar panel circuits to see for how long a solar charge is received by the panels (to help in resiting them to an optimum position), to wire into the wind turbine circuits ditto, and also to wire into the overcharge circuits to see for how long surplus energy is created.

And so I spent a happy afternoon wiring in the overcharge timers and the solar timers. I’m not able to do the wind turbine timers as I need diodes to stop the backflow of energy from the batteries and they haven’t come yet.

The wind turbines are connected directly to the batteries with no charge controller so if you wire a timer in there without stopping the current flowing back from the batteries, the timers will be running 24 hours per day, feeding off the batteries.

I also did some tidying up of the panel that I made a couple of months ago – the one with the 600-watt inverter, the electric meter and the electrical sockets, that I’m using in the barn. That looks neater and tidier, and works better than before.

But I forgot to say that when I was in Brussels at Christmas, Marianne was chucking out an old hair drier – something like 400 watts or so. Anyway, I chucked it into Caliburn and brought it back here.

The reason?

Every now and again I use heat shrink insulation on bare wires and while you are supposed to shrink it using a hot-air paint stripper, I don’t have enough power to run a hot-air paint stripper.

I do have enough though to run a 400-watt hair drier and while it’s slower and not quite as effective, it does in fact work well enough.

I’m quite impressed with that.

Tuesday 17th January 2012 – YOU MAY REMEMBER …

victron energy 1200 watt inverter les guis virlet puy de dome france… the other day that I mentioned that there was a new digital 1200-watt inverter in the post on its way here. Well, it turned up a couple of days ago but I never had time to install it.

Anyway, that all changed this morning and after cutting another huge pile of wood I set about fitting it in the system.

It’s quite a monster and quite heavy too, and the cable is 25mm welding cable. And to fit it on my panel board it involved moving a few things around in order to make the space.

But it’s certainly impressive and if it works as well as it’s supposed to, it will be a big improvement on the current (well, we are talking electricity here) analogue 600-watt inverter, which creaks and groans under the load that it sometimes has to bear but which has kept going for almost three years, day-in and day-out, nevertheless.

600 watt inverter portable power board les guis virlet puy de dome franceThe aforementioned has now been relegated onto the portable power panel that I made the other week which I drag around the outside from place to place when I need power.

As for the 150-watt inverter that was on there that has creaked and groaned day-in and day-out for even longer, that has now been relegated into Caliburn where it will just be used for charging up the laptop and the occasional power tool once in a while, replacing the unsatisfactory 150-watt pulse inverter that only seems to want to pulse when it wants to, which is never when I want it to.

This afternoon I did something that is so unusual as to merit recording here on the blog. And that is something called “tidying up”.

That’s a phrase that is contained in the vocabulary of many people but is somehow missing from mine.

You can’t see much of a difference because I seem to be the only person in the world whose tidying up makes more of a mess that it was before I started, but I’ve recovered 7 square metres of roofing tiles left over from the roofing of the house and the two lean-tos.

I’ll put them on one side for now and think of a way of using them.

I also went into the field next door hunting for the nails that made a bid for freedom. I don’t want the farmer’s cattle to find them first. I recovered a dozen or so but that’s just a tiny fraction of the number that got away. I’ll go for another look tomorrow

But the purpose of tidying up was to clear all of the wood off the floor of the first floor of the lean-to. Where the tarpaulin had been blown away, that area of the floor was soaking wet and the wood that was piled on it, much of it new stuff, was also soaking wet and it was all stopping the floor from drying.

So all of that wood has been arranged tidily where it will receive a nice current of air, and the floor is clear so that it might dry out. You might remember that it was only 18 months ago that I laid the floor and I don’t want it rotting away quite yet.

In other news, I have two companies sending representatives around tomorrow to sell me these roof-top solar panel systems.

I hate these cold-calling canvassers who ring up at 19:15 and 19:45 when I’m trying to drink a coffee and watch a film. Worse than spam e-mails they are – at least you can delete those – and so I’m fighting back.

I can waste more of their time than they can of mine.

And in other other news, the water in the new immersion heater reached 28.5°C this afternoon. Not a lot you might think, but that was 25°C over the ambient temperature downstairs, and that’s well-worth having.

It’s not hot enough to use the washing machine or to have a shower, but we are moving in the right direction.

Monday 9th January 2012 – THERE’S NO POINT …

… in having an early night and going to bed early (well, 00:15 is early for me anyway) if you wake up again at 4:45 and can’t go back to sleep.

Mind you as day started to dawn and I knew that it was soon time to get up, I managed to fall asleep again, and it was 10:15 when I finally woke up. So much for my good resolutions for New Year.

First thing that I did after breakfast was to sort out a design fault on the electric board that I had made the other day. The wires to the inverter were bent at an unnatural angle and the live was touching the earth tag. I had to tape over the ends to insulate them and then drill a hole in the board to run the wires round to the back so that they are lying straight and parallel.

There I turned round the bracket that we had turned when we raised the mast last month and straightened out all of the guys.

I drilled into the wall, fitted a wall anchor with an eye, attached a turnbuckle and then fastened a guy to it all and wound it up to take the tension so that the last is held firm in that direction. That’s one out of the four guy wires sorted out.

After lunch I made a major advance – I started to put the plywood on the roof of the lean-to. It was flaming difficult too – it’s not easy pulling those sheets up on my own, I’ll tell you that, but I have three now fastened into position.

I’m being careful with the supporting chevrons, having learned my lesson from elsewhere where I’ve been working. I’m putting the sheets into position and then fitting the chevrons underneath them so that the sheets are supported in the middle and that the edges of each adjacent sheet meet up over a chevron.

I recall all kinds of bouncing sheets when I was nailing the tiles on when I did it in other places. I don’t want to do that here.

But starting to put the roof on the lean-to. Isn’t this progress?

Friday 6th January 2012 – IT’S BEEN …

… an exciting day today

Having been pondering over the battery situation here – to whit, the house batteries are losing charge when there’s no current and I had ample proof of that yesterday as I attached a little voltmeter to the battery bank and watched it go down and down – I decided to have a butchers at the battery bank.

I reckoned that there might be one battery that was overheating but I was wrong – there were in fact two of them all swollen up. No wonder the batteries were gently emptying themselves.

So I pulled those two out and I’m now down to just 8 batteries.

I’ve been suspecting that these 90 amp-hour batteries are just too small to handle a surge of about 50 amps on a regular basis and this seems to be confirming things. There’s four now that I’ve had to change, and it’s always been the one in the centre of the bank.

You may recall that I went to Paris to the supplier just before Christmas and they had some 200-amp-hour batteries on special offer and so I bought 8 of those. That will be a battery bank and a half.

Ideally I need even-bigger ones but an issue presents it self with that in that these 200-amp-hour batteries weigh 58kgs. While I can pick them up and walk with them, I can’t go far very quickly. Imagine twice the weight.

You might be wondering why I didn’t go the whole hog and fit them today. Believe me, it was my intention. But the battery cables that I have – 225mm – aren’t long enough. I’ve had to order some 375mm cables and they won’t be here until Thursday next week.

portable plug-in electrical board mains 300 watt inverter puy de dome franceThis afternoon, tired of manipulating inverters, timers and the like around, I made myself a plug-in electric board.

We start off with a two-pin American plug with 6mm cable wired into it. This goes to a 300-watt inverter screwed to the board. From there it’s into an electric meter and from there into one of the hour meters I bought in the UK.

Finally it ends up in a 13-amp UK socket.

All I need to do now when I’m carrying out some work somewhere around out of range of the main inverters is to take my little board with me and plug it into the 12-volt circuit.

After that I went to the bank to pay in a cheque, reorder my bread and then go for coffee and a chat with Marianne to catch up on the gossip.

It’s her birthday tomorrow, and that set me thinking about all the other people I know whose birthday it is in January. Krys, Marianne, Marianne from Brussels, Mandy. Those names spring straight away to mind and I bet there are loads more as well (so apologies if I have forgotten you).

It really is astonishing.
