Are the two serial strings joined into a single feed in a combiner box or are they two separate feeds into the solar inputs of an inverter? If the former then only one is needed at the combiner output. If the latter then it's one per string. Also please note that an AC anti surge/lightning protector is different from a DC one so get the right one for the job.

An emp (electro magnetic pulse) from a nearby lightning strike came into my inverters via the overhead electric supply. Internal mov protection was not man enough in two of the three inverters and the ATS. The damage caused was significant and very expensive. Lesson learnt and protection fitted. Protection of the solar panel output is standard and always fitted in supplied combiner boxes. The cost of fitting a protective device is a one off thing for a few hundred Baht whereas an insurance policy is usually ongoing. So I don't think of it as a scam.

Small point but the Lazada batteries you mention are not LiFePO4's. They are NMC's same as used in power tools.

And don't forget surge/lightning protection

On every roof indeed. My idea which is probably same as everyone else, is that all small communities of say 500 households should be independently solarised and connected to each other into a mini grid.

Have you considered paralleling three units of 4 or 5 kilowatt inverters? That will give you all the power you need. Also since you are talking off grid you will have batteries. If the day is a bit cloudy and you need more power than the panels can supply, the batteries will take up the slack so to speak. You might also spend some time to make up a chart of power consumption against clock time then develop a few house rules about what is allowed to run and when. Grid power is a relatively bottomless pit in terms of power availability but solar power needs to have it's limitations fully understood and maybe worked around.

If the 500v inverter input relates to the solar panel input (which it probably does) then the maximum number of solar panels per string would be the sum of the open circuit voltages (Voc) of each panel not exceeding 500VDC. In the example label shown, that would be 500VDC/45Voc = 11.11. That's 11 panels in a string.

Good. But the fire in Chonburi was not at an entertainment center. The building was a restaurant as far as the authorities were aware. Better check restaurants too.

Send me 1,000 Baht and I will tell you all you need to know.

There seems to be and increasing number of scams/cons from sellers on these shopping web sites. I got caught once when I ordered a Razer mouse which was cheaper than it should have been. I received a cheap plastic keyboard and mouse worth a fraction of the Razer mouse. When I raised the issue with the shopping web site, the advice they gave was to go to the police and file a report and let the police sort out the fraud. I didn't think much of that idea and took the loss. I would advise anyone to do what I now do which is to take a look at the sellers "shop". If there is nothing in that shop then I don't buy.

Burnt at the stake before he dies perhaps? Or is that just for witches.

I wonder how many of you have tightened the terminal screw to it's max. But the cable still not clamped, then slackened the clamp screw fully and the cable is solid as a rock. Me too......

Outboard motors don't need much ventilation.

Looking at the amount of damage to the boat, those passengers and crew are incredibly lucky there were no fatalities.

Looking on the bright side just for a moment. Each piece of paper has carbon locked up in it which the tree collected over the years so in a way Thailands love affair with paper is helping to save the world ????

Trouble is that, for me , I have to add cost in time and fuel to get the new brush. My nearest new brush shop is about 12km away.

Just a little more information. There is available in Thaiwatsadu gallon cans of white spirit which I use and is excellent for cleaning brushes. I have recently done some red oxide painting followed by gloss. Cleaning with white spirit makes the brushes almost new again. Another plus is that the white spirit doesn't evaporate very quickly.

Looking really good????

Sorry. I forgot to mention the junior hacksaw blade which I used to weaken the thread in one place.

I had a similar problem with a shower fitting. It was screwed into a brass threaded blue plastic pipe. The metal of the broken fitting was thin and quite easy to brake so I applied a bit of panic + logic and figured that if the fitting could break so easily then so would the threaded bit still inside the pipe. With a bit of judicious poking and levering about with a sharp pointy scribe and a small screwdriver or two, the bit inside the pipe became bits and literally fell out. The threaded pipe was fine and a new fitting was inserted with no problem.

I got caught once by this scam. I bought a Razer gaming mouse (good for CAD) worth over 1,200 Baht and received a cheap and taty keyboard and mouse worth 384 Baht. I now take a look at the seller's store. If they don't have other items for sale I don't buy from them.

A few months ago I bought a Total pressure washer on line. It was a total disaster only running for a few minutes before cutting off and on. Went to Ruangsangthai and got a Bosch with a continuous running capability of 40 minutes plus. Best one I've ever had.

Many thanks for this. Living in Buriram Keyvisa will be the way to go for me.

This is something I will be doing later this year. Being as how I live some distance from VFS, It may be worth using Keyvisa. People seem to avoid giving information regarding price. Please feel free to post how much you paid for this service.

The true test, as has been said before, is can your non-Thai kids inherit your land after you die. I think that would probably be "no". In those circumstances, I would imagine the land would need to be sold to a Thai at some knock down price or taken by a government agency to be sold at auction. As some have said. It is a blatant attempt to relieve foreigners of their hard earned capital.
