Linked one above. I don't bother building power supplies these days, far simpler and cheaper to just buy one.

And a timer. https://www.lazada.co.th/products/digital-timer-7-days-dual-outlet-i4442589628-s17823169857.html

If you want it to go into orbit!! I strongly recommend you don't DIY this. Find a suitable 24V wall-wart and 24V timer or a mains plug-in timer. Stay away from mains. Your valve is 24V 2W so about 100mA.

Australian Energy Market Operator chief Daniel Westerman says emergency rooftop solar switch-off mechanisms must be set up across the national electricity market, to better control “more than seven Eraring power stations” worth of consumer installed PV. https://reneweconomy.com.au/solar-switch-off-a-must-for-all-states-says-aemo-to-control-seven-erarings-of-rooftop-pv/

It's not quite zero, there is a monthly connection fee, about 40 Baht IIRC (don't have a bill in front of me).

Seriously, larger rectifiers (both V and A) tend to have larger volt drops. Let's do this right. What is the current drawn by your valve (should be on the valve)? What is the current capability of your chosen transformer?

Weeeell ...

You will probably need a smoothing capacitor on the output so the valve doesn't buzz, say 1000uF 50V. Also, that bridge is waaaaaay over-sized, look at something rated around 50V 1A ????

Don't panic (yet), it's only money brought into Thailand that's taxable and you may be protected by the Thai-US double taxation agreement.

Wife checked her husband's phone and found these names: Super Woman My Love Woman of my dreams Princess Sweetheart Honey bunny She got angry and called the first number and her hubby's mom answered. Then she called the second number and her hubby's elder sister answered. When she dialed the third number her own phone rang. She called the next one, it was their daughter's phone. She called the next one and it was her own mother and then she called the last one it was hubby's junior sister's number. She cried until her eyes got swollen because she had doubted her 'innocent' husband, so she gave him her whole month's salary to make up for it. Husband took the money and bought this for his girlfriend whose name was saved as #Mechanic ????‍????????‍????????‍????????‍????????‍????????‍????

I do have this t-shirt although it was my employer who installed the bolt! I would have installed a proper 32A Commando socket on sensible wiring but, small company, no money, you know the story.

Generally, PEA is 220V phase-neutral, MEA is 230V phase-neutral. Of course, locally all bets are off due to compensating for overloaded transformers and transmission lines. In reality it matters little as all your kit should be happy with either voltage +- >10%.

NO! Because there is already 220V between any one of the phases and the neutral. If you look at the poles outside your house you will see 4 wires, three of them are the phases and one (usually the top one) is the neutral. If you trace the wires that go to your house (via the meter) you will see that they are connected to one of the phases and the neutral. No transformers or anything else needed, it's just the way 3-phase 4-wire works. Dead handy. 3-phase appliances just connect to the three phases without using the neutral, unless they have 220V control gear. What sort of power consumption would the lift be? Plenty of 3-phase off grid inverters (either single unit or three single-phase units running together). EDIT 2 A quick Google puts the lift motor at around 2HP, that's well within the capabilities of a single-phase installation, check with your chosen lift supplier to see if they offer a single-phase version. EDIT This diagram may help, note that it's for 230V phase-neutral but you should get the idea.

Phase to Neutral 220V your normal single-phase supply. Phase to Phase 380V which is what 3-phase appliances see. The apparent "weirdness" is due to the 120o phase angle between the phases, I'm not going to go into 3-phase theory here, but Mr Google or Wiki can be a lot of help in understanding.
