This is all a bit academic really, though not that academic from a scientific point of view. We first need to establish what SOH is intended to mean and how it should be measured. In my opinion, SOH should be a representative figure for how good the battery's maximum capacity is now, compared...

Sounds like a good plan - it will look in keeping with the extra 8 panels that you snuck onto his roof (y)

My eyesight seems to be deteriorating :(

(y) I'm a VW ID gal :)

You "buy" 1kWh for 7p, but that gives you 0.85kWh to export, which at 12p/kWh pays you back 10.2p. So, assuming your efficiency is similar, a gain of 3.2p per kWh. IMHO, cost per kWh is minimal. Early studies of LiFePO4 chemistry indicates that calendar ageing will likely degrade your...

I've measured the round-trip efficiency of my inverters to be about 85% (i.e. 230V AC -> 48V DC -> 230V AC). So, yes still worth it :)

Yes, but I'd still not recommend charging at 13A anymore. P = I^2 x R, so at 13A there is 69% more power dissipated at any given point of resistance than when you charge at 10A and a whopping 2.6 times the power than if you are charging at 8A. As I keep saying BS1363 plugs and sockets, even EV...

So... does that mean a new MGS5 is heading your way soon?

that's a clever oxymoron :)

Yes, it's good when you need more house / EV charging capability than export allowance. No, worries - didn't mean to be over-corrective, just felt I should clarify those points for others reading the thread.

No worries, we have @Rolfe who knows a thing or two about replacement tyres ;)

Don't all vehicles built in the last 20 or so years allow you to close all windows via a long press of the remote lock button? :unsure:

That is my main concern, but specifically compounded by the fact that a radial circuit only needs one loose connection at one of the sockets (and I've seen that on multiple occasions) to become two radial circuits, each carrying up to 40+ Amps before any solar production is added to that, all on...

not good :(

(y) Not legal in UK and IMHO, unlikely to be. This is because we typically have ring, rather than radial, finals in the UK and applying a secondary power source on the load side of the fuse is likely to end in tears.
