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.

22 is "Europe General", try 40, it can't do any harm and might have broader limits for voltage and frequency.

Are these cells new? It will be interesting to see how they compare with the used golf-cart cells.

Our members may (or may not) be interested in a bit of history, monthly generation and usage since March 2020. Significant system expansion points (total installed capacity). March 20 - 2.4kWp July 20 - 5.7kWp Jan 21 - 6.3kWp Oct 21 - 10.6kWp

If you're not making it you can't store it ???? The road to energy independance is sometimes a bit rocky. But it keeps the brain cells active.

A minor bump on the road yesterday, the solar was buzzing along at just under 8kW (batteries were full) when the output went to zero! Check the inverters via the App, no grid ???? Still drawing energy from the grid so the mains was on. Oh well, wait 'til I get home. The failure was actually on my part. When we expanded the system I didn't replace the 32A MCB on the connection to the car port. Evidently it trips at 34A ???? Probably lost about 18kWh ???? 40A breaker on order, the cable is already 6mm2 so no change needed.

Yeah, we have the 6kW version, excellent inverters. PEA approved so no issues with islanding.

My last information for MG is that they supply a 7kW charger. This will need a 40A circuit, there are some pretty specific requirements for protection, so it's best left to the contractor that MG will send to install for you. Also, I believe they will not install unless you have a 30/100 meter! So it is time to talk to PEA/MEA if you have a 15/45. I also understand that PEA will install a second 15/45 dedicated to the EV if a 30/100 isn't possible. Compared with the EV charger a couple of A/Cs is not worth worrying about.

All domestic class GTIs have anti-islanding as standard, there is no danger to PEA workers (and you are correct, it's not an option that can be turned off). What type of inverters do you now have just to verify?? I suspect that your man is misunderstanding what anti-reflux and anti-islanding are. It is important to understand the difference between exporting energy into a live grid (OK) and back-feeding into a dead grid (very not OK).
