So Andy,
Only just seen this. Do I understand correctly that it was geared to being charged from mains or from a car?
Did you ever adapt it to use solar. Looks like it wouldn't take much. Just add a charge controller and some panels and you have your home made Jackery.

I know you never figured what it cost, but I bet it was a lot cheaper.
You could sue Jackery for stealing your invention.

It does raise the point that energy resilience doesn't HAVE to be about solar. Something like this would be great for coping with rolling blackouts where it charges whenever mains is available.

Thinking out loud..... Did/could you have some sort of mains feed-through to make it like an uninteruptable mains supply?? Such that you could plug your freezers, or whatever into this, plug this into the mains.... And have it so that if mains was on, it just trickle charged, fed the freezer directly and NOT use the inverter, but if mains went off, the inverter kicked in? And if the mains came back on again, it just went back to charge mode? And as an aside, feed the batteries off solar as well?
Is that a daft idea, unnecessarily complicated? Am I over thinking this?

Is that something an unqualified person could do safely and legally or is that a step too far with electrical regulations??

Everything is possible take a look at this where I got my inspiration from..

It's since had a Anderson plug added for solar charging from my 60w Bosch panel 😂 my intention though is to join the new 100w panel with a 50w I already have ( bought flexible as they will survive the upcoming England football star in the garden) already got a charge controller to suit in a drawer ..

The 20a caravan PSU/ charger is continuously rated so could provide 20a continuously...

With tye added advantage of shoving 100ah back into the batteries in 5 hours like you say was intended for rotor cuts :) the Inverter hasn't got a remote switch which would be needed for remote starting taken from a contractor switch module in the event of a grid down it would then start rather than leaving it on standby all the time
If your roughing it, Your doing it wrong ;)

Lack of planning on your part doesn't make it an emergency on mine

That video is indeed inspiring. I don't expect to come close to the elegance of his system. He's clearly qualified.

A few instant takeaways from the video though.....

600Ah +100Ah Batterys!!!!!! Bl006y hell!!!!!
Economy 7 dual rate electricity??? I had to check that's still a thing. It is, sort of!

But the biggie...
He seems to be feeding his whole house from the ONE 13A socket in the back of his inverter!!!!! So I googled the inverter..... It's just 1500W !!!!!
An expensive, quality 1500W
Plenty for lights and the odd fridge and TV.
Obviously he avoids using the kettle, toaster, microwave, shower, washing machine, tumble dryer,. To turn any one of those on would surely overload the inverter?

He implied he could switch to charge mode every night and inverter mode every morning, manually, to save money???? That would be a chore.

Off to watch it again.

Lots for me to think about now. I'm awaiting delivery of my inverter and have started seriously hunting for VFM panels.

Shell energy is trying to get my mum and dad off e7 and get them to install a smart meter.. unfortunately for them my dad told them to get erm "lost" even with the after August the meter might not read correctly... :tinfoil so dad says it's either going to be in your favour or mine and he can monitor it :mrgreen:

Dad's worked on power stations / commercial electrician so well err yes that argument is dead In the water
