The mob that made mine, make single 3.7v cells from 40ah to 10000ah (no thats not a mistake- a ten thousand ahr 3.7v single cell...) so you can spec up practically everything from a small UPS supply, to powering a factory... just select the cells you need... Once people actually start looking...

You obviously have no idea of how far battery tech has advanced... ;-) I am currently running off 10kwh of lithium batteries (half my eventual bank of 20kwh) and they are literally the size of a medium to large suitcase... That's half the bank (2 series strings of 4 x 400ahr to give 12v in...

A lot depends on the local regs- I'm well and truly out of date re the UK solar/hybrid battery scene unfortunately... In Australia, you are required to use only approved battery boxes for gridtie systems, which limits you down to Tesla (not very popular here- overpriced for the storage capacity...

Same still applies- a switchmode can run quite happily off any waveform, as the first thing it does inside is rectifies it to DC anyway, then uses a high frequency oscillator to 'chop' the DC to a square wave AC waveform (usually in the tens of khz region) ie the same as the old kettering...

Actually- 99% of modern electronics not only don't need a pure sine wave inverter- many don't even need AC at all!! Seriously- anything with a switchmode power supply in it (that 100-250v 50/60hz label on it) will run straight from the DC battery bank of many modern offgrid houses- which often...

That's exactly what mine will be doing once the house is built- the house will be a 4 bedroom one with all electric cooking, electric HWS, led lighting, and aircon (must here where I am in Australia- summer days can hit 43C plus for days on end and in summer nights will often be over 25-30C as...

I haven't bought a replacement battery since 2014, according to the dates written on my batteries- I have bought a few aftermarket elcheapos to fit my dewalt stuff, and then when their batteries fail (usually within a few months at the usage I give them LOL) I repack with quality cells (usually...

I been living offgrid (third time in my life) for the last year and a half in Australia- this is a 'temporary' setup to supply power to my shed and caravan- only 3kw of panels (1.5kw north, 1.5kw west) feeding 10kwh of LYP batteries (half my future house bank) and a 8kw 12v inverter (stayed with...

Firstly, the issue was masked by the battery in the first installation, and when it was installed, the sheep weren't even thought of (indeed they didn't make an appearance until several decades later) The original installation was done by an electrician (now retired) known to me, and he was...

Yup- although I plan on a complete DIY system rather than a prebuilt as a basis... Ive built several systems in the past (one at my sisters, another at a rellies farm) using linear actuators and a simple remote system with reversing relays- hardest part was 'finetuning' the emergency 'stop and...

It was originally speced for one gate opener and a driveway light only, they then replaced the original gate opener (after several decades) with a different one that was mains only, rather than the battery with mains charger of the previous one, and that was when troubles started It was all done...

I am in the process of homebrewing my own here, solar charging a battery to run the opener and remote system (plus a camera/intercom for the drive)- its a 500m driveway, so running a cable is obviously out... plus its an offgrid home anyway so running mains would be a bit pointless in my case...

30 x 100ft- thats a warehouse.... in metres thats 9 x 30m.... I have a farm shed here thats slightly smaller- 9x25m (4 bays, so yours would be a 5 bay equivalent of mine... another 'door' longer in other words...) But mines on 30 acres.... big difference.... To give you an idea of the size we...

I have one here that I bought back in the 1990's- so yeah- they have been around for a while.... ;-)

I had to say I was unaware of how far that was..... I have to drive a third that distance just to get to a McDonalds or Bunnings (Australias 'big name' hardware store....) So just a quick trip down the road then LOL

Yup- practically every town here in Oz has a 'Men's shed' (although many have women members too lol)- a great idea thats taken off hugely here with the aging 'baby boomers' who often downsize their properties to a smaller place- but find their 'shed' collection is simply too big for the new...

He was screwing a brass nameplate up to the front of his letterbox using selftappers- which were a bit too big for the holes in the nameplate- one bit into the name plate and spun it around with the bit as the self tapper bit in, and because he was holding it with his fingers, the edge of the...

Yes, but thats true of any powertool really It's up to the user to make sure they have the knowledge of what they are doing (the manufacturers can put warnings on the box and in the instruction manual- but so many don't even bother to open those.... Then it all comes down to the Darwin...

That's one of the reasons I have so many, jobsites are just so much easier with cordless tools (and I do have to say that mine have been used to the point of being replaced over the years, Despite the original toolkit coming with THREE drills (2 speed heavy screwdriver light drill, extra heavy...

A trick I have used quite successfully is the 'adapter' units- you can get them in almost any combination of batteries available, makes 'sticking to your brand' far less of a 'must' because you have already got such an investment in batteries or whatever My first was a DeWalt 18 to 20v adapter-...
