Second system extension extension.

"A" level? Surely power (Watts) = Volts x amps is absolutey fundamental - and only simple arithmetic too? After that (kilo)watt-hours is just how long you have drawn that much power, and therefore how much you owe. (...if you can multiply the consumption by the price!)
I agree that most learning of "facts" is pointless (apart from how SI works: kilo.mega etc,) and that applies especially to trignometrical values. If you use them a lot you will learn them, if not it is safer to look them up!

I cannot understand how our politicians (and their SPADS who know even less, but are presumably more determined to push their vested interests) have driven education away from teaching a simple understanding of basic concepts. I suppose it makes it easier for entrepreneurs to rip off the public who don't know - or can't even make sense of - arithmetic, so the barrow-boys can continue laughing all the way to the bank.

Yep it’s all simple once you understand it. Electricity, magnetism, projectile motion, thermodynamics, nuclear physics, and the rest.

You just have to see people write “watts per hour” or something else that betrays that they have zero grasp of the fundamentals. This forum is packed with people who know more than the average person about how electricity works. The wider community are utterly clueless. A product of teachers who prioritised memorising facts for an exam over a genuine understanding of the fundamentals that will last a lifetime.

Guys, tbh. As I age I am finding myself relearning things that were once just right there, life's been busy and I think the Hdd is a bit full! I also try hard not to fall into the trap of 'others know what I know' so will happily state the (apparently) obvious. People learn in all sorts of ways across varying cultures, seeing the light bulb go on was one of the most satisfying parts of mentoring followed closely by watching lads confidence grow in my working career. I hope that 'we' as a group manage to do that for many people over the years.

I have told myself a million times: "don't exaggerate!" (Joke!)

You don't need to actually, really understand any of those things to be able to cope with what everyone needs to be able to use. Watts times hours - watt-hours. More appliances conected, more Watt-hours. I couldn't tell you how magnetism and electricity are linked numerically, despite having Physics A-level and working in a science lab most of my life. I still don't understand how the basic physics (power relationships) of electric motors was worked out with old-fashioned magnets, when nowadays we get so much more power from motors (and generators) with the new magnets. Maybe the motors have greater output because the coils cut more densely packed lines of magnetic flux?

I used to have arguments with a friend about maths: to him (very deeply involved in it) it was philosophy and he thought people should be working towards understanding it. I said it's just a tool that 99.99% of the population need to be taught how to use.

(and teachers have to teach what the exams demand, regardless of what they were once taught to deliver. The Clergyman's Daughter by George Orwell talked about that 50, maybe 70 or even 80 years ago - but in the context of a small private school where the parents demanded that the children could recite lists of Capital Cities etc.) Again, after the 1970's, politically-driven SPADs were instrumental in changing education policy regardless of what research and professional knowledge indicated would be needed. Us? we taught our kids to cook, even though domestic science and CDT had been merged and perverted into "Design some packaging that will help us to sell this manufactured snack."

I am SO glad to have grown the system. Our son is using our home when he finishes work for cooking, washing machine, pc gaming etc and since we have been away it's been entirely off grid. That makes me feel great! No way I'd be saying this pre battery & PV extensions. It IS getting to the thin edge now in the mornings pre sun yet way better than any previous year. The shoulder months have narrowed.

Hopefully these power price surges will trigger thousands to extend their arrays and make it just a little cleaner?

Ordered Sunday evening from Earthwise, arrived Wednesday first thing.
The sensor wire is only 1.5m long! The manual says that it can be extended to “4m if needed”. I hope this doesn’t spell trouble as 7m would be nearer the distance from the consumer unit to the airing cupboard.
By the way, that’s a 2.5mm jack plug on the sensor.

Are you going to get one of these: https://www.amazon.co.uk/dp/B00L5FVWVK/ ... TR683JX2JG? Or are you going to use one of these: https://www.tradesparky.com/solarsparky ... ransformer from Joe's new favourite retailer! (I don't know if there are different connectors for different models of Solic).

That jack size is too big and be careful when getting a different CT as they are not all the same (Different ratio and voltage outputs).

It is more than just "fluctuating prices" our reliance on imported FF gas for electricity generation, space-heating, and cooking, is handing vast amounts of power (no pun intended) to Uncle Vlad!
