Very, very expensive price but nevertheless don't forget to factor in the increasing cost of PEA power. If DIY that price of 400k could be halved and most components doubled.

House value is increased significantly if free electricity is included. ????

OK so looking at the suppressors they each have a Uc (continuous working voltage) of 800v which effectively means they will only suppress voltages over 800v I suspect that is higher than the components of your inverter would be happy with. The suppressors need to be somewhere in the range of 329.7v minimum to 500v maximum. It would be nice if you could find one with Uc of 450v https://shopee.co.th/Suntree-เสิร์จกันฟ้าผ่า-SUP2H-PV-DC-SPD-500V-2P-20-40KA-กันฟ้าผ่า-อุปกรณ์ป้องกันฟ้าผ่า-Surge-Protection-ซันทรี-ธันไฟฟ้า-SSS-i.303694660.2960555499?sp_atk=0289ebcc-e17f-4047-acce-39f10d304d1b&xptdk=0289ebcc-e17f-4047-acce-39f10d304d1b

Another question or two What it the maximum open circuit voltage of the panel array? What is the maximum solar input of the inverter?

Your PEA meter and that of your neighbour both became u/s at the same time so something happened on the PEA line. What is the distance from the PEA meter to your PEA input surge protector? What is the distance from your PV fuse to your PV surge protector?

Something like this. https://shopee.co.th/ฟิวส์พลังงานแสงอาทิตย์-PV-DC-1000V-PV-Fuses-10A-15A-30A-แรงดันสูง-ป้องกันระบบสุริยะ-ไม่ใช่ชุดเดียว-i.516543065.15598785952?sp_atk=258598d3-0d81-4e68-841a-ec4381c991a9&xptdk=258598d3-0d81-4e68-841a-ec4381c991a9

You have almost certainly had an EMP event from a nearby lightning strike. It seems your surge arrestors in the solar panel incoming circuit did not trip the DC isolator quick enough and the pulse(s) were big enough to bypass the built-in surge arrestor components inside the inverter. The PEA meter damage also indicates a surge. Probably the same lightning EMP. Yeah indeed as I would also. Sometimes natural events can be bigger and stronger than we can anticipate. The only thing I can think of to prepare for the next time is to put some high speed fuses in the solar panel feed. This should ensure that when the surge arrestor conducts, the surge current will instantly cause the fuses to blow and break the connection before damage is done. Maybe the DC MCB was a bit too slow.

Is the incoming surge arrestor in good health and did the incoming breaker trip?

Do you have surge arrestors on you incomer from PEA? If you do. Are they located immediately after the incoming power breaker/isolator?

There's also a very good chance, being as how the electricians were there for a different purpose, the guys didn't even look at your meter concentrating as they were on getting their bit done so they could go home early. Preparing for the worst is a good strategy though.

Our 93 million mile fusion generator is actually working 24/7. The reason we can't see it all the time is because some silly soul keeps spinning our world round. Clouds are a bit of a problem but that only diminishes the energy we receive. Having a decent battery ESS (energy storage system) is definitely useful for dark times but this is a whole load cheaper than buying a reactor. For example. A 36kwh set of batteries would set you back 150,000 baht and would last 10 years. This works out at 1,250 Baht a month. This is conditional on a few details, but I don't think there are too many reactors that cheap. Made in China? Who cares.

Not at the railway crossing in Buriram. Bells and lights and barrier-lowering all at the same time. The man in the trackside shed doesn't give a monkeys about what is happening on the crossing. I have seen slow moving traffic get trapped between the barriers. Fortunately the man in the trackside shed saw it too and raised the barrier to allow the car to proceed and get off the track.

You keep beer in your pocket?

Buriram office asked to see the bank balance again one year but for the past two years they haven't asked for it.

The 400k needs to be in the bank on the day of application (+ previous 2 months). That is the immigration requirement. However this "under consideration" thing may mean there is a possibility of having to do the application again so funds are needed in the bank. This whole thing of "under consideration" stinks in my opinion because, many years ago when I first applied for an extension, the wait was two weeks or thereabouts. Under consideration has crept into the rules and may not even be official. Perhaps someone knows if it is in the rules now?

Or not. Those were the days of two pin, five amp mains plugs and sockets so there was a 50:50 chance of the chassis being very live. Or in my case more like 95:5.

Anyone remember the live chassis radios? It got rid of the mains transformer and also the ground wire in the power plug. One of the deadliest innovations ever. Modify one of those at your peril. My electrician father did exactly that by adding a ¼" coax plug for an extension speaker. He connected the screen to the chassis. Nobody noticed anything until one day the plug accidentally contacted a water pipe. My concerned mother made certain that radio went off air 'till the mod. was removed.

There used to be a factory in Bedminster, Brislol called Will's which made Will's Woodbine cigarettes. The first floor was taken up by a huge valve computer programmed by thousands of punched cards. Those valves had to be frequently swapped and tested on an AVO valve tester and valves below par were placed in the reject box. I had quite a few of them which were good enough for my various amplifier projects. Incidentally the heat from the valve computer was ducted around the factory to keep the workers warm.

Yes they are the connoisseurs choice, and price too for that matter. Available on line. The only thing I can say about valve sound is that the distortion is such that some things actually sound better to some people.

Aah yes. A sweep generator. Didn't use them much. Simply screwed the cores up and down a bit 'till you got better undistorted sound or 'till the core shattered. Did a lot in connection with SAWF (Surface Acoustic Wave Filter) in the early 70's which replaced IF strips in TV's

Strange but I've just been reading about how gullible the Thais are.

As others have noted. It's not 20 years away but more like 93 million miles away and working.

Stopping them working is easy. The difficult bit is getting them to work in the first place.

And food being nicely warmed up in the fridge. This is why we should all have solar.

Not sure about "wobulators in the testers" but there was such a thing as a wobulator which had the job of making the spot wobble as it traversed the screen. The idea behind that was to try and fill in the gaps between each of the 405 lines. Which were quite noticeable on a 21" screen. I managed to wreck a few CRT's by "rejuvenating" them. Zapping the cathodes to release a few more electrons worked mostly and could put off buying a new tube for a few months. A friend of mine, aged about 20 at the time, fancied himself as a TV repairer and was given a 21" B&W TV to fix. It had a series connected heater chain driven through a mains dropper and no heaters were showing. Safe in the knowledge that the tube heater was at the high end of the chain, he decided to connect the other end of the mains to the dead side of the heater. For about half a second the cabinet was flood lit fantastically. The owner was quite forgiving since it was an old set and my friend decided on a different career direction.
