Change of Batteries Use, winter 2022 -23, New Strategy.
Since last year the Energy structure in Europe has become very difficult, with loss of cheapish Ruskie fuels, and poor planning by Governments.
Here in France we were official warned by the French Government that they might have to implement rolling power cuts across France because of Electricity shortages during the winter.
Yes, they dragged old Nuke stations back on line and started all sorts of other energy saving measures and public messages everywhere.
However, what that has meant for us is that when it’s get dark here in France I have to ensure my battery pack is full or well charged to stand 4 hours of NO POWER in the night time.
'Hang on', i here you say, you are Off Grid?.
Yes, we are but we do use the Utility EDF, (government controlled) supply as a standby generator, as here it’s cheaper than buying, servicing and fuel costs on running a 15KVA Generator. On our 22-year-old Sustainability and RE Project, we do have 9 separate buildings to also supply. Here in France, we have 8 hours during the night period of very cheap electricity tariffs that’s when we use the EDF utility virtual generator especially in the winter months.
So this year we are re-thinking our battery storage 1300ah 48vdc strategy.
Yes, we will still have them as we need them for the buffer supply when AC Coupling as we have 30Kw of PV, and those 9 buildings requiring power. But I will have to put my thinking cap on and closely look at what the longer implications, future proofing required and of course the ROI.

Good idea to start the planning stages well in advance.
We have a new "smart" meter that now tells use the charges for peak times and off-peak charges.
Since we are at work during most of the peak time, I have timers on all of the heavy loads that turn off everything not absolutely necessary to keep the animals safe.
It certainly does help!
How goes the battery builds?

Hi Bruce,
Yes, its that spring time of year where i have loads of jobs that i am slowly getting done.
Having to build a small steel frame and oak open-end barn for the Tractor grass cutting equipment. Still working on restoring and passive house works on the 1700's Old House. Structural repairs and old-fashioned brick laying where the old lime mortar has washed out. As the weather is not cold/freezing as much now so work outside becomes possible again.
Also started squaring up my Oak plank timber i have had for jobs, about 60 planks rough sawn from the mill, with my big table saws and chop saws, planks are about 10 foot, 6 to 10 inch wide and about 1 1/4 inch thick. Also means i am doing those requests from family about oak work tables etc, sigh!
Still got to electrically wire up the 60 year old Deutz tractor lights, horn, indicators, warning flashing lights etc, before i can go on the public roads agin. Everything is repaired renewed and tested, but needs me to put in correct thickness new cables, which is a job i am not looking forward to. !
PLANTE battery project still progress but slow, each plate roller ribbing takes about 15 minutes, so 28 sides means 7 hours of work per battery. I try to do 2 plates a day when i can, but i am also working on the Geotextile 400gms thick polythene socks for each plate as they get finished.
Also sorted out the design for the main positive and cathode buss bars, especially not keen on just resting each plate on the main buss bar, so doing a slot in the bus bar for each plate that then can have a lead cotter pin arrangement to lock the plate for a good electrical connection. Need to work out the cotter pin so it can be removed with out to much difficulty.
Once all the Plates have their socks, and the polypropylene 10mm by 10mm grid sheet stiffener between the plates, then i will know the exact dimensions for the case so i can start working on that as well.
So yes, work continues.
I trust you and the family are oaky. ?

Do you have a way to store energy as heat, and use it later?
Bruce S:
Family doing very well. Amy's NOT coming to the EU this year, she was asked to come back to Greece by the group at the Iklaina dig, but the Professor, requested she give a few Freshmen a chance to go.
Robin's still cooking!!
After another brief time off, I'm back at work!!
I do have a Pin-OAK tree I wish I could send you! 25' dia last guestimate was right at 100+' that got hit by lightning last big storm. That's when you're glad those arrestors are in place along the roof line and chimney are in place!!
That tractor!! I'd love to come help rewire it!! I didn't find it in the posts, is it 6Vdc? OR?
Ya know, if you ever "HAD" to , you could use it's generator to charge the batteries ;D. I trust it's GEN is original gen and not an alternator.
Good the read about the batteries still coming along.
You still brewing?
Cheers
