- ended up instead making "insulated jackets" for the batteries instead on the house north wall.
Any pictures of what you did?

22kW fast chargers (64 Amps, per phase), plus two Powerwalls charging over 6 hours (20 Amps).
Do you actually need that "peak"? Or can they all PowerShare in some way? My PowerWall steps down (from 10kW to 3.5kW I think) if I have a car charging at 7kW. That obviously means that PowerWall won't fill within its normal timeslot ...
And if the Car Chargers PowerShare - so that rather than all of them start at midnight and be done by 10-past they charge the cars sequentially (or in parallel but at lower AMPs) - would that do?
I'm thinking that 22kW (if car supported it) over 4 hours = 300 miles - would it be rare for you to need that? on two cars the same night? (I'm just curious as to real world scenarios)
I think there’s a terminology/organisation issue here. AFAIK the National Grid has nothing to do with domestic installations. They don’t have a problem supplying sufficient power via their top level backbone. The issues are at the distribution end of the supply networks … so the issues/challenges described are the responsibility of the DNOs … of which there are several, most likely with different policies depending on their local infrastructure and demand.There's also one other reason.
National Grid limitations.
At the moment, while all this is 'novel' ... it's fairly 'easy' to get stuff signed off.
But I also think in the future, National Grid will seriously start limiting what people can have.
Get in early, have it all.
Get in late, get nothing.
"National Grid" is the new name of the-company-formerly-known-as Western Power Distribution.I think there’s a terminology/organisation issue here.

There’s a recipe for confusion! We now need to call the original National Grid the ESO …"National Grid" is the new name of the-company-formerly-known-as Western Power Distribution.
They are the DNO serving the West Midlands and (if I'm not mistaken) a chunk of North Wales.
Quite a confusing change! Everyone used to know what we called the National Grid … but this new National Grid isn’t even a National grid . Nevertheless it’s useful for us all to keep track of whether we are talking about the ESO (old National grid) or one of several different DNO companies.Western Power (DNO) are now National Grid (DNO).
So my terminology for my area (West Midlands) is accurate.
Things are changing all the time...

The DNO are at ours in a few weeks, to finally unloop us ( detached property but on the end of a loop of another two houses).
Road up, both paths, block paving up, meter cupboard at front of the house ( lovely), jointed and -later- reinstated.
All gratis .
Not sure what they'll make of the solar and batteries, I've not sorted the legalities with that yet.
House to the side of mine has a 7.2kw charger.
Looped to their next door, the DNO aren't bothered as and I quote " it's been installed for a few years and it hasn't caused a problem yet".
just to clarify:Just to clarify my comment above about the Smart Meter...
DNO's can't physically move Smart Meters. Only the Electric Utility Provider can do this. So it complicates the job, waiting for each Organisation to do their bit...
However, a DNO can move an analogue meter. So the job is much more fluid and less delay / inconvenience to you. Once it's relocated into the new meter box, you can then apply for a Smart Meter upgrade whenever you want.
just to clarify:
DNO has to provide exact date/time of move and power supplier can disconnect and reconnect meter at the same time/date. so you can do it all in one go.
been there couple of months ago (insurance claim)
Sadly, I have a Smet2 meter now ( autocorrect turned that to Smethwick, how awful)Ask them for a 3 Phase Upgrade, free of charge.
I did... they agreed.
BUT, you MUST ask them.
They will upgrade to 3 Phase cabling, and a 3 Phase cutout, but only connect one phase to your meter. You can then decide what to do later.
Don't upgrade to a Smart Meter until after the work is complete, preferably...
