Just a thought (from a non electrician), If you turn off the incoming power, then try to turn the MCB on will this show whether the MCB is faulty? If the MCB fails to stay engaged it would indicate that the MCB is faulty as there is no power to be tripping it? If the MCB engages then it would indic...

any ideas for people wanting more than 80kwh in an outbuilding?

something other than a line of individual sheds with batteries in

Don't kid yourself that 48V is in any way "safe". The dangers are just different! Drop a spanner across the battery terminals and you'll get a face full of molten steel! I've replaced a few 48v forklift battery packs one heavy 2v cell at a time, tools wrapped in tape when I can;t find the...

Have you read the other thread? https://camelot-forum.co.uk/phpBB3/viewtopic.php?f=14&t=3619&p=55168#p55168 Particularly section 6.5.7 "The total stored energy of all units in an individual dwelling house shall not exceed: a) 80 kWh where batteries are installed in one of the following...

Sounds like a good project! What are you going for WRT pack voltage? Up until recently 48V was standard, nowadays you can get so-called "High Voltage" (don't get me started) inverters that work from 80-480V (or similar). Are the LEAF modules you're getting 2S or 3S? Does their connector e...

good point, my brain automatically went to tig rod without giving it much thought!

could always bash the flux of a stick welder rod?

as above, adhesive heat shrink - I like the welding rod but also.... layer up the heat shrink, 3 or 4 layers, and make then longer than needed... each bit 2inch longer than the bit under it if it got bashed/broken somehow and needs protection, sleeve it inside a bit of water pipe? a roll of 15mm pex...

I found some Nissan leaf cells on Facebook, bought 72x gen1 (brand new never used) cells from the guy pretty cheap Talking to him, he does battery swaps on cars for a living, has supplied loads of cells to people making home battery storage, has some bms setups etc. etc. Went to see him again about ...

the 2.5di engines in them are indestructible, they run forever with pretty much zero maintenance I can remember helping my dad when I was a kid, we'd only service them at MOT time, normally we'd go to check them and there'd be no water in the header tank and no oil showing on the dip stick, we'd cha...

keep your eye out for a turbo for it, or a knackered turbo van you can nick the parts from

it's shocking the difference it makes and how much nicer they are to drive
