I guess that device was his backup power. Would he normally run off 220v do you think? Perhaps he needed a backup for his backup supply.

This is totally wrong. It suggests that the governance should be absolute with no debate to ensure that decisions are both technically and legally correct and therefore acceptable to the electorate. I think it's about time reporters were allowed to present alternative opinions based on what politicians tell them. The PM and the government should be accountable to the country and this cannot happen so long government decisions are kept secret.

Yes. That was my first thought. Normally, medical devices made for life dependency have their own independent power supply rather like a UPS. It could be that this ladies device either malfunctioned (flat battery) or was of non-medical origin (not from a hospital). Whatever. PEA did what they always do and had the meter removed after two payments were missed. Happened to me when wifey forgot to pay a couple of times. Didn't notice straight away because I have what you might call whole house UPS in the form of solar with batteries.

Make the pavements bigger and ban all non-electric vehicles........😀

Following this to a conclusion of some sort, this onward reduction in embassy workload will end up with no visa's issued and therefore none needed to enter any country. 🙂

Please, anyone who even thinks about nanny state control, go bury yourself. Enforcement of safety rules is totally the most necessary thing needed to prevent so much loss of innocent life.

That sounds, to me very much like Rasputin the Russian monk. I wonder if there is a connection in there somewhere, to the Kremlin.

He's an expert without a doubt. https://www.area.co.th/english/president.php Ph.D. Land and Housing, Asian Institute of Technology (AIT), Bangkok.

If I was as well qualified in my chosen field I would undoubtedly be regarded as an expert to whom all others turn.

There are no dangerous roads in Thailand. There are, however, millions of drivers who occasionally drive dangerously with scant regard for the rules and/or the safety of themselves and others.

As a rice farmer myself, hand planting is still by far the best way but it's labour intensive and needs controlled irrigation. I do direct seeding with a tractor drawn seeding machine and send the wife off to the temple for the rains.

We desperately need a Groan emoji..............

I'll give Banksi a call for you if you like. He's good at that sort of thing.............

Great news. How was this installation financed? It should be government policy to fit solar power to all government buildings.

Doctors in Thailand are very well trained in terms of which medicine is good for which disease. Unfortunately some of them don't seem to get the same level of training for detecting variables between one patient an the next. Giving "catch all" medication is not necessarily a benign solution as in this OP case.

Bon voyage m'sr

The OP's picture is of the external unit so no drain pipe. This problem is in need of an expert AC engineer since it could be serious in terms of AC units. Call the man in from the shop installation company.

I have often wondered about these modified wagons. The ones with extra long bits on the back and the ones made wider near the top. They must be carrying extra weight greater than is permitted. At the weigh bridge "Over weight? That'l be 5,000 baht sir".

Don't forget the electronic tags from a few years ago

In UK second hand car showrooms, all second hand cars have the price displayed on the windscreen so you can easily see if it is affordable. Why don't they do this here in Thailand?

For further reading and because I'm way too lazy to write so many words, have a look at this. https://www.alternative-energy-tutorials.com/photovoltaics/photovoltaic-panel.html

Simply put. A solar cell is made from a reasonably pure silicone sheet. Each cell is "doped" in a vacuum during manufacture with different gases which will modify the silicone into 'N' type on one side and 'P' type on the other. Thus an NP junction is formed similar to a diode. It is this junction which is termed 'P' type that has a forward bias of ≈0.5 to 0.6v. However the solar cell is sensitive to light and it's this sensitivity which gives us the ≈0.5 to 0.6v when light shines on it. This is the open circuit voltage with no current flowing. There are panels on the market now which have a higher junction voltage of ≈0.63v and also a better temp. co. The silicon diode has a junction which, although made the same way, is slightly different and designed to carry a specific amount of current in one direction. There are many different types of silicon diode the small ones (1Amp 'ish) will have a forward voltage drop of about 0.7v. Larger beasties can be ads much as 1.1v. This is why schottky diodes are better for higher currents because their Vfwd is considerably less than a bog standard 1Amp 1N4007 for example. As an aside, transistor radios used to be made with not silicon but germanium transistors. The OC45 comes to mind. If one were to scrape the paint off 'em they would make excellent light sensors but at a fraction of the price of purpose made devices. After a while the plastic encapsulation was made opaque which put a stop to that cheap trickery.

I find it a bit disconcerting that all we ever seem to hear about is the tourist industry in Thailand. I believe that is 20% of the economy. It would be interesting to know what the other 80% is earning for Thailand and a few success stories to go with it.

All solar panels that I know of have diodes in their junction boxes on the back. These are bypass diodes. They are there so that if a string of three panels has a failure of one cell on e.g. the middle panel, there is a current path through this diode to allow the remaining panels to continue functioning after a fashion. the solar panel itself is little more than a whopping great big diode. This is why, on the face of it, you don't need blocking diodes. But solar panels are not designed to be blocking diodes and so additional protection of diodes in the combiner box is considered to be necessary.

I have never heard of any that don't have blocking diodes. Why would anyone build a combiner box without diodes? Mine has 25A Schottky bridge rectifiers cunningly connected to accept two inputs each.

There are things called combiner boxes which allow safe connection of multiple, parallel strings. These boxes also have lightning protection and fuses for each string. Otherwise it can be regarded as a junction box. The output goes to the solar input of the inverter. If you do this using the combiner box there is no need to worry about different outputs from each string as they are effectively isolated from each other. The output from the combiner box will be a balance of the panels best outputs and none will be dragged down by it's less capable pals.
