I have suddenly found myself unable to get news stories on Microsoft News. I can get the headline blocks but they are blank if I try to open them. Does anyone else have this problem? Has it been barred from Thailand for some sinister reason?

It mock's the system that created it. Just imagine a civil servant dreaming up a form like the life certificate. Hardly ever been outside his home town. Thinks the rest of the world operates similarly to his/her world and does a cut'n past job on signatories. Not a thought about how to check the authenticity of anything outside the UK. Assuming that postal services around the world are the same as in UK. (They have a list of safe postal service countries which includes Thailand). Whilst having an exchange of emails with them, as soon as you suggest making a change from post to email for delivery of blank forms to you, they immediately send a separate email informing you that if you want a change you must put it in writing via post. Brainless?..........Yes. Almost completely.

Reading this one could be forgiven for believing that the only musical instruments in the world are guitars.

This is about Sterling/Baht. Are you talking USD?

Agreed. I was being a bit tongue in cheek but couldn't find the emoji. Having said that it was 75 before I got here and yes @freedomnow those were indeed the days for all the best reasons.

I think I'll hang on 'till it gets back to 72...........

Government workers probably.

And got paid for it............????

Yeah. Perhaps I should qualify a bit by adding Competent electrician.

You should get an electrician to do the replacement since you already said you have no knowledge of electrical things. The electrician may also need to be good enough to go hunting for the orginal fault which caused the RCBO to keep tripping.

I'm trying to buck that trend. Once you're past 85 are you in the "safe zone"?

Ha Ha Ha Considering Thailand is something like 90% "out in the sticks" that makes Thai post only reliable in 10% of Thailand

@Calmer You can go to their website and leave a message. They will respond within 24 hrs https://secure.dwp.gov.uk/ipc/personal-details

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.
