  1. For ESS you might like to look at NeFe storage cells. They are not cheap but the chemistry is good for 30 years or more. Focus on the TLC. It may put you off The price is good but only over an extended period' I like it, but I'm old.
  2. If I were you I would take the two (or however many) battery cables to a common bus bar and then have a single cable from that to your isolator/MCB. The thought also occurs to me that the cables may be bigger than they need to be.
  3. Quote from Johns Hopkins medicine: https://www.hopkinsmedicine.org/health/treatment-tests-and-therapies/lithotripsy#:~:text=Lithotripsy treats kidney stones by,pass through the urinary system. "Lithotripsy treats kidney stones by sending focused ultrasonic energy or shock waves directly to the stone first located with fluoroscopy (a type of X-ray “movie”) or ultrasound (high frequency sound waves). The shock waves break a large stone into smaller stones that will pass through the urinary system." It seems there is a bit of exaggeration going on here. I'm sure this non-invasive treatment is available in Thailand. This ex DSI man is taking the piddle.
  4. I bought a plastic box about 300L x 300H x 150D with a front door. I put my own window in and also fitted a power meter (volt, amp, watthr) which I rarely ever look at. Inside the box is a backplate for easy assembly. With a load of glands, all the cables went in and out the top.
  5. They are all in Buriram. The best one is London Steak opposite the Isuzu place in town.
  6. You might like to look at this web site https://www.nuvoair.com/blog/do-you-know-how-to-interpret-the-results-of-your-spirometry-test
  7. And don't forget the panels are also giving better output in this cooler weather.
  8. Yes it is something else. It's a combination of food quality and quantity. People have more money to spend on food so they eat more but often the diet is of poor quality. That, coupled with lack of calorie burning activity, leads to an unhealthy lifestyle and overweight.
  9. Very similar but mine does need regular lubrication with refined snake oil.
  10. I have been working very long hours these past few days on my design of a translucent energy force field and am now in a position to offer it on pre-order for 500,000 TBh per unit. One unit is sufficient to protect 2 x 340W panels. PM me for further details.
  11. I don't understand the reason for highlighting this woman's job as a civil servant. That has nothing to do with her trickery or his idiocy. Unless, of course, being a civil servant is seen as training for such.
  12. Buriram seems pretty busy too however most of the crowd are not tourists but are Cambodian workers.
  13. Best protection is an insurance policy. On the other hand, the savings made in electricity costs could be banked ready for such disasters.
  14. Aah yes. That'll be Murphy's Law.
  15. Some people are so lucky ????
  16. I really do like that display. It's a simple, no messing about indication of what is happening overall.
  17. Also issued there and then in Thai embassy in London. UK seems to be a second class service in comparison.
  18. Sods Law ????
  19. This is an interesting thread. It reminds me of when I did some bus bar work for a Korean company. The bus bars were big and copper and were to carry around 80k Amps for an electroplating plant. Torqueing the many bolts was very specific because the copper has a certain amount of elasticity which needs to be retained for expansion-contraction purposes. Too much torque and this elasticity is lost and the joints will become loose. In order to have the right pressure between busbar surfaces, we used special spring washers under the bolts which had to be compressed but not flattened.
  20. That would be quite normal. What I did was to place a breaker/isolator in series with each battery before the parallel connection. This is to ensure that if a battery goes faulty, ie short circuit, then current from the other battery will trip the breaker. My batteries are Gel not lithium. With lithium there should be a BMS for each of the parallel batteries which should protect the batteries from each other. It's always useful to include a breaker/isolator for maintenance for each battery.
  21. Will there be an escape route for the water between the pipe wall and the slat wall? Or are you planning for a fish farm perhaps.
  22. The PEA eng. was quite interested in my system and the discussion covered FiT at which point we both had a good laugh and the conversation moved on.
  23. Snakes eat rats so bring 'em on. I have quite a few snakes so the rats go and live else where which is good for my rice storage barn. Your builders concern is probably a reflection of his (and Thai villagers generally) fear of snakes.
  24. No they didn't Some years ago when I had a 1kM temporary supply, I shared my line with a new neighbour who paid the bill. I was on solar 100% at that time. Along came the monks and the Amphur head man and hooked into my meter for a bit of loud music. They were having a dedication party for a newly built Budhist shed just down the road from my house. The Amphur head man nominated his best village electrical engineer to do the hookup. This wonderman of electricity also swapped my live and neutral so connecting live to my ground through 1kM of 25mm² aluminium cable. The cable got warm and the meter spun round quite merrily racking up a 4k Baht bill for the day. My new neighbour didn't 'arf complain to the PEA about that so they sent a posse of engineers round to inspect the cable from the meter through the trees to my house. We had quite a discussion at the time about the ease of access to my meter and all sorts of things solar. So PEA were very much aware of the non-use of the meter (except for my neighbour). The Amphur head man was persuaded to pay that bill and promptly sent his electrician (Mr. Wonderman) to correct his mistake. Of course, this happened over a week or three so in correcting his mistake he didn't check first to see if I had already done so. You should all be ahead of me by now. I had already corrected this swapped wire problem so when the wonderman came he effectively did the same again. That was another 4k Baht bill only this time the Amphur head said it was not his problem so we had to sort it out ourselves. The upshot of this story is that PEA office were now intimately aware of my solar activities so are quite content to leave me and my rarely used meter in peace. By the way, I have had my proper supply for a few years now but I had to wait almost 8 years to get it. Such is the speed of progress.
