The Mill Market in Rangsit has some small turbines in the car park. I drive past every weekday afternoon on the way home from work. I have never seen them actually going round ????

RCDs (just earth leakage) and RCBOs (earth leakage with over-current) are readily available in all the big-box DIY places (HomePro, Global, ThaiWatsadu etc. etc.), usually 30mA but 10mA are available. There is also an add-on box branded Safe-T-Cut which is an adjustable (30mA or lower) RCBO in a box, a bit expensive but handy to add on to an existing system. At least a front-end RCBO is a requirement to pass the MEA or PEA inspection for a permanent supply so every new build "should" have one. "Chint" are a mid-range Chinese manufacturer, major brands like ABB and Schneider (Square-D) are readily available along with a plethora of "off" brands. We installed ABB RCBO units when we built the house, but assorted add-on circuits have Chint and Chang units as what was available in the store at the time.

Ok, since this seems to have gone political / pro-anti EV bickering I'm going to lock it. Our OP has his answer. Want to re-open? Give me or any online mod a really (really) good reason.

Is your son Thai or foreign?? Let's shift this to the special covid forum for detailed discussion.

Please!!

We are in much the same position, were MG actually happy to supply but not install the charge box??

What sensitivity is it set to?? If you post a photo we can show you how to tell if it tripped on over-current or earth-leakage.

OK I'm going to lock this pending review by The Bosses.

Those with solar might have a look at open EVSE https://www.openevse.com/

It's well hidden down Thailand Extra forums, Community forums. Or here https://aseannow.com/forum/4-farang-pub-fun-entertainment-and-expat-life/

I have found the True live help (in English with video chat if needed) works very well, so if you are struggling to register ...

Yeah, you have to be prepared and logged in whilst in the line.

Persevere with True Money, once you're actually registered it works well. Note that you will need a Thai ID (pink card) to satisfy their KYC (know your customer). IIRC a WP will also work, but I used my pink card.

A photo would be good. And is it going off on earth leakage or over-current? One lamp shouldn't be tripping the beast, inrush wouldn't be that big on a domestic install (it's definitely a problem on large installations). The surge arrestor shouldn't making any difference, could possibly be the extra cable length. Most odd.

Absolutely totally me too!

Love the way he looks around furtively before the snatch!

Meanwhile back on-topic. This is the Great Wall Motors "charger" installation instructions (in Thai but Google Translate works well enough). home-charger-installation-gwm.pdf

We now have (since last October) 32 panels totalling 10.6kWp. Really bad day (18/03) gave us 15.7kWh, best day recently (30/03) gave a very satisfactory 42.8kWh.

But some do, @Thaifish can confirm ???? Note that there's an important difference between it running backwards (ours does) and it being seen going backwards by the meter reader (ours isn't).

Good point @007 RED although our OP has 3 x single-phase inverters so will have 3 x CTs (one on each incoming phase) so he will need to arrange to switch all three. My ESP8266 based unit could be modified to drive a 3-pole relay to do the job automagically.

Update:- The Irish SAS have arrived, killed the gorillas and released the ostriches.
