When my ev ohm charger was installed they needed to see earth bonding points on my ch pipework and water pipework and took pics before they would install the charger.

Things are different in Scotland, but id imagine in England and Wales you would need a spark to connect you to the CU and ensure your rcbo's are small enough to protect your wiring and your wiring was big enough to take the potential load.

Domestic electrics are pretty straightforward tbh, it's generally single circuit (ev charger for instance, or oven)
Parallel circuit (lighting generally)
Or ring circuit which is basically a Parallel circuit with a return (sockets).

Everything is a single voltage too. 240Vac

Id argue that if you wanted to be by the regs, you would get a spark to wire up your inverter on the AC side as most of the DC batts are 50V, and when it comes to it, doesn't really matter if you have 1 x 50v battery or 100, as they still have to go through the inverter which is wired by the spark who will (we hope) ensure the correct level of wiring, isolation and rcd /rcbo protection.
I could be swayed by an argument of the spark also being responsible for installing any DC isolators, but id struggle to see the need for a spark sign off on the 50V DC side after isolator.

My lux inverters are the same ones which started with i think 6kwh each and now have 30kwh each.

I'm sure that my installations are electrically sound, I mean, my kids live in this house, right?? whether an insurance company would decide I was legally competent, I couldn't say.

When i rewired my house as part of adding an extension I got a spark to come and do a full test at the end with a few grands worth of fancy test machine to certify all was good, it was required for the final sign off.
However that spark told me that I didnt have enough earth in the house, and I needed to connect all my radiators and plumbing to it as that was my main earth, or something to that effect.
He advised I should fish out the earth's I had just cut on twin and earth cable going to double insulated potlights/downlights (as they only took connections to live and neutral) and reconnect them all too, so as to add to my earthing capacity.
I believed him, and conveyed that message on here and was basically told it was a load of tosh, the earth comes from the supply.

Why bring this up, because I feel qualified and competent are not the same thing, and that works both ways around.

If you have lights, you're supposed to run an earth all the way to them even if the light fitting is double insulated.  Because light fittings can be changed, and the next one might not be double insulated.

Yeah the T&E is ran all the way, but when 2 wires go into a fitting and you have a spare conductor floating about you can tie it up, tape it up, or cut it back to the sheathing, I cut it back

The Seplos V4 kit is cheaper at ~£1140 but requires more work - including top balancing, if the description is correct (the cells in my kit last year were already balanced):

Set one of these Seplos kits up a few months ago. Cell balancing is built in and worked well. Remarkable value and has performed to specification so far without issue.
