  1. Inverter units are much more tolerant of low supply voltage, but they behave as constant-power loads, lower voltage means they pull more amps => even lower voltage ... Exactly the same real issues as using an AVR. I'd hang on until PEA come up with a solution unless you can get a suitable AVR (about 3kVA) to just run your larger A/C for a sensible price to bridge you over the hot period.
  2. Do check your historical transactions. I've noticed that Lazada refunds, whilst taking to the "next billing cycle", actually appear on the statement at the date the refund was processed (so if you were refunded on Feb 29th look there on your online transactions) so that could be well in the past.
  3. Indeed, although in the case of LiFePO4 packs if the hydrogen is being emitted there're rather more serious issues afoot. Now, if we are using lead-acid then ...
  4. Hmmm, great minds ... Also a Toshiba of similar vintage! OK, it was Madam who installed the bungee, my claim to fame is that I made the cat keyholder when I was about 6.
  5. At least the flood will put the fire out! Seriously, Lithium-Iron-Phosphate (LiFePO4) chemistry is much safer than the NMC (or Li-ion) chemistry used in your smartphone, scooter, hover-board, monowheel and a lot of EVs and has a much-reduced tendency to "thermal-runaway". Many suggest that they are at least as safe as lead-acid (which have a different set of safety issues). LiFePO4 will burn if persuaded but most incidents involving them seem to be of an electrical rather than chemical nature. At least, that's how they start, a shorted LiFePO4 cell will out-gas and one of the products is hydrogen which is somewhat flammable. Concentrate on good electrical design and implementation, adequately rated cables protected by suitable breakers and/or fuses. It's far better to avoid starting a conflagration rather than to try to extinguish one. Our friends at the National Fire Protection Agency (NFPA) have things to say about ESS installation and location. Chapter 15 is the relevant bit for domestic systems. <Removed copyrighted document, plenty of places to download it> EDIT You can view direct from the NFPA website for free (you have to create a free account) start here: - https://link.nfpa.org/free-access/publications/855/2020 EDIT 2: - Actually, you can view the latest version too.
  6. Ignoring (for now) the actual chemical energy that's contained in the various battery chemistries (some are rather more "energetic" than others). It is worth remembering that a 10kWh battery pack (about 200Ah @ 48V) contains about as much energy as a litre of petrol/gasoline. Treat your batteries as you would the gas can for your mower! Once our packs are fully configured, we will have >60kWh of storage, about 1.5 US gallons of gas! That's staying well away from our home!! If it decides to go "whoosh" we may lose the car-port and the car but the house should be well out of range.
  7. That's not a breaker. THIS is a breaker! The 250A DC MCCB which I intend using as an overall battery isolator sitting next to one of the more regular MCBs we find in our homes!
  8. Mike Pinder, a singer, songwriter and keyboard player who helped form the progressive-rock band the Moody Blues and was among the first and most prominent exponents of an early electronic instrument, the Mellotron, died April 24 at his home near Sacramento. He was 82. His son Daniel Pinder confirmed the death but did not provide a specific cause. Mr. Pinder was the last surviving member of the original lineup of the Moody Blues. https://www.washingtonpost.com/obituaries/2024/04/25/mike-pinder-moody-blues-dead-obituary/
  9. I'd go for the wood strip on the wall, a nice piece of dead-straight hardwood would do the trick and look ok too. Pack behind it where your wall is less than straight.
  10. This is what 28kWh of DIY solar storage looks like. That's 16 series sets of 2x280Ah cells in parallel (2P16S) for 48V x 560Ah. The empty space top left with the small burn mark is where my 5A "flying-capacitor" active balancer was until it emitted the Magic-Smoke. New unit on order.
  11. Yeah, embassy websites are often out of date or simply wrong. According to Washington DC - https://washingtondc.thaiembassy.org/en/page/visa-exemption US citizens only get 15 days visa exemption by land ...
  12. Could you post a link to an embassy site or two that make this statement please? With no credible source it's just unsubstantiated rumour.
  13. OK I stand corrected. The best option would be to remove all doubt and extend after he returns as @Liquorice suggests. He would have to ensure the officer at the airport does stamp him for the few days. Last time I did something similar he noticed and asked if I wanted 2 days or a 30-day exemption, but you never know.
  14. My understanding is that the "Under Consideration" period counts as a new extension and so invalidates the existing Re-entry Permit. I've been wrong in the past mind. So, whatever his dates are he will need a re-entry permit for the under-consideration period. Of course, you can guarantee that, if you ask your immigration office and they say "no need", you will meet an officer at the airport with the opposite opinion. IMHO it's worth the cost of a single re-entry permit to remove all doubt.
