Interesting coupleafew days. Much impressed with how a little bit of tech, a smidge of experience, combined with a decent round Robin comms forum setup and a whole load of professionalism can turn itself into a multiman smooth order of a large batch of LF280K V3 grade A cells from the fair China and hopefully a boost on this forum for a tremendous young fella. Photos to follow... Cheers Colin Deng! :xl:

Joyous. :twisted:

I'm in Spain mildly spangled on teq sunrise (again). It's 05.31hrs in Shenzhen, plus it's brand new Chinese New Year. The cohort is i hope, happy back in Scotland.

Colin literally rocked through Chinese New Year start, cracked on, well, well out of hours, got it all lined up deep into his night.

Deriy by comparison are 10 days out & counting, late for answering simple questions, plus they bullshitted to one of the cohort and have subsequently lost out massively.

I hope they continue to, Colin rocks.

No comparison, not even close. See it, say it. :D :)

15.8kW PV SE, VI & DW
Ripple 7kW WT & Gen to date 11MWh
28kWh LFPO4 storage
95kWh Heater storage
12kWh 210ltr HWT.
73kWh HI5
Deep insulation, air leak ct'd home
Zoned GCH & Hive 2

I can easily tap into the current busbars on the system which then go back through the fused Frankenstein switch to the Pylontechs. Although i'd like some way to isolate the new stack from the busbar Hence a pair of upgrade isolators at the new build.

Thanks Nowty, ordered a pair this afternoon. SWMBO's like 'are you going to disappear down the hut for days again'? I'm like.... :twisted: :xl:

Just one bit of advice, the split pin that goes into the handle is too big or the hole is not big enough. You might have to drill / file out the hole or squeeze the split pin a bit to get it in.

You do get two split pins though in case you feck up first one. :xx:
