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.

There's no "may" about it!! They also show PWM charge controllers which are hideously inefficient. To be honest, that kit would be nearer to 100W than 1,000W, sorry.

Do you have an actual link for that? 850mm x 680mm = about 0.5m2 With the absolute maximum insolation from our local star being about 1kW per m2 that panel is 200% efficient!!! Most real panels are about 20% efficient. A 330W panel is about 1m x 2m. Something doesn't add up.

Where are you getting 1,000W panels for 1,500 Baht?? A 1kW panel would generate about 3-4kWh per day of decent sunshine. It would also be about 3m x 2m and weigh ... Direct EV charging (DC) from solar is an emerging technology = $$$ Easier would be to use a simple grid-tie inverter to supplement your grid energy usage whilst using the "granny charger".

High tide today, slightly down on yesterday 🙂 The calm before the storm??

If your prospective load is over about 10kW (which would max-out a 15/45 supply) then the supply authority will likely want you to go 3-phase. Some locations will do a 30/100 single-phase supply (20kW or so) but it's by no means a given. And, as our OP notes, he has 3-phase machines. Also, having 3-phase gives you some redundancy. It's common to lose 1 phase, with a 3-phase supply you still have two good phases. You can even get automatic selectors that pick the "best" phase for your essential equipment.

Just how big are the A/C units you're looking at? The problem with 3-phase equipment is that the loss of one phase will take your kit down. And. By far the most common failure mode of power supply here is the loss of one HV phase (it's always the one our single-phase supply is on)! Cue no A/C despite you having at least some lights and outlets. If you have 3-phase machines, get 3-phase for them, but treat the rest of your home as 3 single-phase installations.

Apparently, reptile eyes are sensitive to blue/green so it might dissuade the beastie, but the call of food may be stronger. Jinjoks will certainly chase the red-dot of a regular pointer in case it's potential food.
