  1. At the sort of power levels we are talking about you just connect the inverter as if it was a regular appliance, you could even (temporarily) put a plug on it and plug it in to an outlet. Purely for testing of course Important Note: A domestic grid-tie inverter will not output anything unless it is connected to a live grid (island-protection) so even if you put a plug on it there's no danger of electric shock, unlike a generator which will happily kill you!
  2. @Bosscat Do you have any actual 3-phase appliances? You could consider using 3 x single-phase regulators like @carlyai suggests (not a single 3-phase one) to regulate your supply or maybe go for 3 x single-phase protectors and retain the 3-phase one for any 3-phase appliances.
  3. By PM please, not on the open forum.
  4. There are certainly solar power / solar assist A/Cs about, but they are not cheap and not very available here. Your best bet would be to install a grid-tie solar inverter which would offset daytime usage whether A/C or not. If you have an old type spinning-disc meter it would go backwards if you made excess power (not permitted of course) A 24kBTU unit will suck about 800W on average when down to temperature so adding a 1kW grid-tie solar inverter and 3 x 340W panels would get you in the right ball-park and not break the bank. Maybe go a bit larger and offset all your daytime consumption. Personally, I'd go for a mid-range grid-tie inverter of about 3kW (have a look at Sofar units) starting with 5 or 6 x 340W panels and see if the "free" energy bug bites. Are you going to DIY or use an installer??
  5. If you believe your contactor is faulty you should replace it with exactly the same type (all the numbers and letters specify coil voltage, contact form etc.). What does your contactor actually do in your system? If it's an under/over voltage protection there should be a controller too where you can set the trip voltage.
  6. In an EV you (or your dog) can sit in the cool for as long as you like without upsetting anyone with fumes
  7. It actually sounds like your pump pressure tank is getting waterlogged. If bleeding it fixes the issue for a while, then the only solution is a replacement tank, they're not expensive. Are you quite sure you have the correct technique for your pump, Google the pump type and "bleeding".
  8. The problem is, if it's a dedicated 60Hz transformer then it may overheat even on 100V 50Hz, running it on 110V 50Hz would make that issue worse. I agree that it would "probably" be OK, but in my business "probably" isn't good enough.
  9. As the subject of said anecdote I should give notice that I'm in Cairo until the end of May and so won't be able to do my usual round of visits. The view from our office.
  10. You mean Bob declining a drink?
  11. John: (entering shoe shop) Uhm, miss! My wife asked me to buy her these shoes, problem is I just don't remember her size. Saleslady: Ah no problem sir, here, hold my foot so you can estimate your desired size. (and John held and measured the foot of the saleslady) John : Yes! Maybe it's ok miss, I think you're the same size,.. I'll buy them! Saleslady: Ok sir! I'll just put them in the box, then you can pay for them at the counter. John: Oh, by the way, I almost forgot,.....my wife was also asking for a bra and panties, I don't know her size either!
  12. Ideally, they should be on a separate circuit with RCD protection. But I admit that our gate opener (and Madam's koi pond) is plugged into the second outlet of our water-pump socket. The outlet is on an RCBO and happens to also feed the range hood and igniter. All our outside lighting is solar but I'd be tempted to use low-voltage lights with a power supply in a protected location if you want to use mains-power.
  13. Growatt do have a big following, pretty good bang-for-the-buck but support appears to be somewhat, er, "variable".
  14. Generally, inverters with multiple MPPT inputs allow them to work independently, so different voltages are quite happy. Best to download the manual for your proposed inverter to check. Also, if you intend adding storage "later" do check your inverters can run without batteries (not all do). We are also in the process of upgrading and I'm going for 3 x Deye 5kW hybrid units running in parallel for a total of 15kW coupled to 70kWh of 48V LiFePO4 storage. At about 45kBaht a pop the Deye units are not exactly cheap, but they are a well-known and respected brand with (apparently) reasonable support.
  15. I'm afraid that this is Thai banks all too often, no idea what they are looking at so it's filed as "too hard, go away!" Great that you got it sorted and thanks for the update.
  16. The owner of a large company was confused about paying an invoice, so he decided to ask his secretary for some mathematical help. He called her into his office and said, "You graduated from University and I need some help. If I were to give you $20,000, minus 14%, how much would you take off?" The secretary thought a moment, then replied, "Everything but my earrings."
  17. Please note that this "relaxation" does NOT and will not apply to AseanNow. You want "free speech" you know where to go.
  18. Yeah ^^^, I've found Google Translate/Google Lens works pretty well for one-on-one conversation, but it's not so good in meetings particularly with multiple background conversations (as is common with Thai meetings). It also needs a pretty good internet connection for speech translation.
  19. Yeah, works for me too. The actual address is https://nsw.doa.go.th/nsw/ The login/registration page https://nsw.doa.go.th/public/index_en.php has an "English" button.
  20. Yes, this is possible, we had an example a while back where L and N had become swapped at the meter! https://aseannow.com/topic/1250930-earth-rod-is-hot/ A pretty extreme example but it's definitely worth checking your supply polarity.
  21. Saint Peter is at his desk near the Pearly Gates when a dirty white Ford Transit pickup stops at the entrance. Inside are three travellers. He looks at them with distaste and asks “What do you want?” “We’ve just been killed in a road crash and we want to come in.” Peter replies “We don’t want any of your sort up here.” “Well this is the Kingdom of Heaven, you don’t refuse anyone if they’ve repented their sins.” Peter says “Wait here a minute then, I’ve got to go and ask the management.” He goes off to find the Almighty. Peter finds God sitting on his throne, and tells him what has occurred. “Go back and tell them all are welcome, let them in.” says God. “Oh, very well then” says Peter, not very enthusiastically. Five minutes later, Peter returns. “They’ve gone.” “What, the travellers?” “No, the gates…..”
  22. "Cat-fight on a flight" - got the title all we need now is a screenplay
  23. That we are remembering these says something about the impact they had on us!!! I was a member of the Tufty Club! You?? I also admit to having owned a Robertson's "Golli" badge
