Time to find out what these MCBs control and investigate, I'll bet the damp has got in or the local wildlife has had a nibble. If not already done, pop off all your outlets and light switches to get any damp or creatures out. Madam's hair-dryer is a useful tool! Since you can get two MCBs active, check what they control (and record) so you at least have an idea what not to look at.

That's probably the only currently accessible copy of that website in the known universe! The WaybackMachine is down after a cyber-attack although they say that the data is safe and they will be back "soon".

I bet you have a N-E fault on your shed circuits. Disconnect all the neutrals from the neutral bar, hopefully it then won't trip. Then put them back one by one until it does. This kind of fault can be a nightmare to find so don't lose heart. Of course, if you had an insulation-tester ...

Surely that's a plug-in hybrid because it combines human energy with battery

Yes, it's a question of voltage and control. Most EV packs are >300V most domestic solar is 48V. There are direct solar-EV solutions available but they are relatively new and not inexpensive. https://enteligent.com/products/enteligent™-tlcev-t1-trusted-charging-presale At the energy levels involved this is not a DIY job!!

Sounds like you definitely have an issue of an earth-leakage nature 😞 Does it trip with the main breaker in the shed switched off? I'm assuming that this is a 2-pole breaker.

Mount it on a drone 🙂 Give it a FPV camera and you can zap beasties from your armchair

Does your meter actually read Zero with nothing in the clamp? Use the "rel" function to get more accurate readings.

High today, still pretty stable, long may it continue!

Well this has to be a world-first! Over the years I've bought loads of 32650 LiFePO4 cells with varying degrees of success! Our garden floodlights are powered by "Franken-Packs" made up of matched sets of the rather less good cells (some are absolute junk). Space in this case is not a constraint. I have an application where space is a constraint, i.e. an upgrade to grand-daughter's e-scooter which currently has knackered sealed lead-acid batteries. Luckily, I hit paydirt with this seller. I think they are a reincarnation of a seller I had good results from in the past who then had a load of iffy cells and vanished. Anyway, these Tipsun "6,000-6,500mAh" cells actually test at >6,000mAh. Get 'em whilst they're hot! https://www.lazada.co.th/products/i1927620957-s6091720828.html EDIT Before anyone asks, no I'm not affiliated in any way shape or form with this seller

If going the recommended hybrid inverter route, you would get inverters that can run in parallel (not all can) and tell them they are configured for 3-phase. They talk to each other over an RS-485 link.

I do wish that people who post "confused" emoticons in a technical forum would actually post WHY they are confused, then we can take steps to un-confuse them 🙂

They differ in that the three phase voltages are at 120o to one another. If you are using one phase then phase angle doesn't matter but when you use all three then it does. It's just a fact of life that swapping two phases cause a 3-phase motor to run the other way. There's plenty of on-line tutorial stuff on 3-phase or you can get the text books I used long, long ago 🙂 EDIT This is the exact version we used 🙂 https://www.amazon.com/Higher-Electrical-Engineering-John-Shepherd/dp/0273400630 That image brings back some (not always good) memories of Bath in the 1970s

A number of members are already doing it, some with multiple EVs.

I can see now why you need 3-phase, that is one big home. I'm amazed it was actually on a single-phase supply at all. Do verify whether you are MEA or PEA (look at the meter or the one next-door) as MEA doesn't go that far out of town. We are in Greater Bangkok and on PEA. 130m2 of panels would be in the order of 21kWP and would generate about 70-80kWh per day (very much dependent upon the weather). I'd initially look at 3 single-phase inverters, one per phase, say 10kW each. Certainly go hybrid even if you start out with no batteries.

I really hate this kind of advertising as they put the solar industry in a bad light when they come nowhere near the advertised performance. Somewhere in there is the disclaimer, not found it yet.
