I've not actively looked for them, but try one of the specialist electrical places rather than a big box store, and ask for "fire rated" downlights. They will probably still need to order them, but at least they should understand what you need. Find some photos on the web, a picture speaks a thousand words. Somewhere like this, it's a lot bigger than it looks, they have a massive warehouse out back and as a bonus it's next to the bottle shop: -

Whilst this is undoubtable the case, our OP is a new build and he won't pass the PEA inspection for a permanent meter with ungrounded/2-pin outlets. You can safely plug 2-pin appliances into 3-pin outlets, the reverse is not the case. The additional cost for a properly wired system is insignificant in the overall scheme of things. I would also recommend running a neutral to light switches, you won't actually need it until you do, and it's a pain to retro-fit.

It's never too late. The last survivor of the Sampoong Department Store collapse in Seoul, 19-year-old Park Seung-hyun, was rescued 17 days after the collapse, on July 15, 1995.

There's very little available in English, however the Thai requirements are very similar to the Aussie regs AS/NZ3000, if you wire to that you'll be good to go. The only point where you may go adrift is the Thai method for implementing MEN (providing a neutral-earth bond) the incoming neutral is routed via the ground bar. See the diagram below (my translations). The original PEA document is here it may be worth printing it out for your sparks. Groundwire Mk2 book-Manual.pdf that's a Onedrive link, let me know if it doesn't work for you. Real and "pattern" Wago connectors are much more available than when we built our place but many Thais haven't seen them and will require instruction in their use.

There's no escape It does appear to be a legal obligation under the Statistics Act, B.E. 2550 (2007) , although I don't see any specific penalties for non-compliance. EDIT The act is here for those really, really interested https://thailawforum.com/database1/the-statistics-act.html

For clarity this is the online census form, it expects one form per address, I don't know how it works for condo dwellers, perhaps a member could enlighten us. https://popcensus68.nso.go.th/?set_lang=en and the NBT announcement https://thainews.prd.go.th/nbtworld/news/view/1025516/?bid=1

There's an old guy who collects used oil from our family restaurant (at one time he was paid to take it away, now he actually pays for it). He filters it (coffee filters) and mixes it 50-50 with pump diesel. It runs his old indirect-injection Nissan pickup and the local farmer's iron-buffaloes just fine (it's going nowhere near our common-rail diesels). The exhausts definitely smell of fried fish!

This issues with adding capacity to existing UPS units are mainly: - The electronics (including heatsinks) are designed to run for as long as the standard batteries permit without cooking (value engineering). You can mitigate by adding ventilation and fans and/or improving the (minimal) heatsinks. And. The inbuilt charger was designed to charge the designed battery capacity in a reasonable time and may never actually be able to charge your extra packs (bigger capacity, longer charge time and larger leakage). Add an external charger to at least get your external batteries to a point where the internal charger can maintain. It is certainly possible to expand run-time with external batteries, but it's never as simple as just nailing on more battery capacity. For extended run time at reasonable power levels, it may be more economical to get one of the baby "silent" generators and retain your UPSs to keep things alive whilst you start the generator. We were doing this for several years before we became a solar household.

At least the raw material is free.

Sustainable, made with fresh materials - Yup I'll go with that. USED cooking oil in an aircraft - No way Somchai. The same stuff as proper bio-diesel, ok. If the truck stops nobody dies. Will we ever know which airlines are actually using this stuff??

Done 🙂 Fixed the quotes too.

The recent 7.7-magnitude earthquake in Myanmar has disrupted solar wafer production in western China, where about 50% of the country’s wafer capacity is concentrated. Major manufacturers have suspended operations due to equipment failures, raising concerns over supply shortages and higher global solar prices. A wafer shortage is expected. JinkoSolar noted that wafer prices had already risen nearly 6.7% before the quake as the peak solar installation season spurred stockpiling.

Of course. It still has the factory seals!

Remember this? I bought one for our boss at BTS, he was over the moon, his young son was equally delighted 🙂

What nobody has realised yet, is that the model in the photo is what they are getting

A mate in Seoul got a dose of the creepy-crawlies. Being shy he didn't go to the pharmacy, he used fly-spray!! This was definitely not wise

Something like this https://www.lazada.co.th/products/powmr-2kw-12v-20-150vdc-pv-bulit-140a-mppt-solar-charger-controller-2-i5482290007-s23263269028.html coupled to a 12V 250Ah ish LiFePO4 battery would be more than wonderful (maybe 2 x 100Ah would be cheaper).

What kind of mouth ballcock wash do you use? Doesn't it sting a bit

How much power (Watts/VA) do you need and for how long? There are certainly UPS units that can take external batteries but they tend to be the more expensive variety. Or, you could use a solar hybrid inverter without solar panels and just a battery pack. The world is your oyster then 🙂

It's apparently illegal to be out in public without underwear (or to drive without a shirt)

Generally, for both your inverter and a generator you will need a transfer-switch, it is vital that you never have both your inverter/generator and the mains connected together (unless the inverter is a grid-tie type). If you have a hybrid inverter like @carlyai shows it has its own internal transfer arrangements, but an external switch is always handy as a backup if you need to service the inverter. @DD86 What is your actual goal in life for this setup?
