What happens is that the solar (or wind) charge during the day gradually increases the charge in the battery from the overnight figure (about 12.4-12.5 volts is a good figure) up to about 14.1 volts if it’s a good day.
Once it’s at that figure it maintains the charge for a short while to give the batteries a chance to warm up inside and to shake loose any oxides that have accumulated, and then it goes into PWM mode, which is where it distributes the charge equally over all of the batteries and balances the incoming charge against the outgoing load.
When it’s happy with all of that it goes into FLOAT mode where the circuits close down until the charge in the battery drops to about 13.4 volts, and then it all starts up again and we repeat the cycle.
So today was the first day since October (I think) that we all went into FLOAT mode, even with the fridge running throughout the day. Three good days of solar charge has done wonders for my system.
This morning I was woken up by Antoine ringing me. Mind you, it was almost 10:00. I’d slept through all of the alarms again. I’ll have to do something about that. Then Antoine phoned me again, Claude came round for a chat, Liz phoned me twice and Francois phoned me once. I’m still in demand as you can see. I’ve never been so popular.
Today I made a start on the garden. I’m resiting my vegetable plot as you know and so I need to clear a place to move the old Ford Transit, the Merc and the British Salt Cortina because it’s under where they are currently that the vegetable garden will be. Back in 2002 all of this was cleared out but all these years of neglect has seen bushes, shrubs, brambles and trees grow right around everything. First job was to cut down a tree that was about 15 feet high and about 2 inches in diameter. That’s grown since 2002!
I could get at the back of the old Transit then and so I took off the towbar. I’m going to let Terry have it to fit on his new van. His is a 2005 model and rear wheel drive so it should fit okay and the tow bar is doing no good at all to anyone, rusting down a field. Older readers of my blog will remember the old Transit. I was on my way to a ferry at Caen to go to the UK for my OU science lab work when I had a puncture. You know that I prefer steel-belted radial tyres to textile belted ones. I’d been travelling at high-speed for hours and so the tyres were quite hot, and the blow-out occurred with such force that it blew the tread and the belting off the tyre. The steel belting spun round like a flail and ripped out the side of the van and the nearside wheel-arch and floor. Mind you, the van was 16 years old and it had seen much better days but it was still a mess and not fit to be driven on the highway after that.
But it’s going to be a lot of work to do this garden. I’ll have to start making the borders for my raised beds.
In other news, the UK is getting weirder and weirder. Some woman has been given a suspended prison sentence for breaching an Anti-Social Behaviour Order. And the Anti-Social Behaviour Order she has breached? Well, her moans and groans during lovemaking are too loud for her neighbours, and they played a tape of it in the courtroom. Personally, I cannot imagine anything so pathetic. I reckon that what it is is that the neighbours are just thoroughly jealous. I remember telling Nerina that it would be nice if she would moan while we were making love. And sure enough, half-way through the next performance she said “when are you going to paint this ceiling? It’s been like this for 5 years. And the walls need papering too …“
Mind you, I did once live next door to a couple whose lovemaking was exceptionally noisy. But never mind the ASBO – I always wanted to give them a round of applause when they finished. But you know how it is – you can’t clap with just one hand.
