I know @JAS21 (same inverter) was seeing some throttling earlier in the month and was experimenting with a fan.

Certainly, a tad warm, but nothing to worry about yet. I thought it might be throttling the output at about 3PM, but it's just the sun has gone AWOL.

Yeah, there's a pretty big glass recycling place near us. Beer cans (I seem to generate rather a lot of them), old lead-acid batteries, scrap steel etc. are all bagged up and sold by family for a bit of extra income. The bin-pickers really don't get a lot of joy with our bins.

Have you tried pulling the plug, having a coffee, then plugging it back in? I really do not recommend trying DIY fixes on a microwave, parts of the works can remain LETHAL even when the beast is powered off and unplugged. There's probably a local "man" who fixes stuff, ask your local bike taxi guys (they know everybody). At 12 years old it's really end-of-life and a new one is in order.

Gold surely

Not stupid money, but a bit of an investment for just a couple of joints https://www.lazada.co.th//products/i2375968786-s8049639239.html Or ask at your PEA office, many of the PEA chaps will moonlight for very nominal fees.

As noted earlier, these are the chaps you need https://www.lazada.co.th/products/gtl-16-gtl-25-gtl-35-gtl-10-compression-copper-aluminum-cu-al-tube-bimetallic-crimp-terminal-cable-wire-connector-splice-sleeve-i4435668268-s17778761147.html? along with the correct crimp tool. Complete the job with adhesive-lined heatshrink and you're good for many years.

For domestic level kit it's just the normal grid-island protection built-in to an approved inverter plus surge suppression, proper grounding arrangements and Type-B RCDs. Check out the PEA website, there's a bunch of stuff there, in Thai of course. If you go large, then there's a whole new world of hurt! Do let us know how you get on, if PEA/MEA are actually making life easier to get on the export wagon that's really good news.

This!!!

Our "battery" works the A/C too

It's getting the darned cover back on that usually stumps me ????

That's rather over-size compared with the standard Thai guesstimate of 600-700 BTU / m2 which tends to err on the big side.

Missing neutral or a phase-neutral swap can get most "interesting". Surge supressors and over/under trips are definitely a wise investment.

Inverter A/C units are much more tolerant of low voltage than conventional types due to their power supplies being "smart". If you don't already have surge arrestors, I would certainly be looking at installing them, modern inverters are pretty robust (early ones died rather too readily with surges) but every little helps. For whole-house AVRs, have a read here: -

Turbine blades I agree, but things are improving. Solar panels are mostly silicon and aluminium with (very small) traces of other stuff, recyclable or at least benign in building materials or (horror) landfill. Even those "horrible" lithium batteries are >95% recyclable.

This is the place for you https://aseannow.com/forum/319-alternativerenewable-energy-forum/

A metal roof may well fare better, yes we have concrete tiles. The steel in the piles / footings does not need to be exposed, Google "Ufer Ground" or "Concrete Encased Electrode", we have a goodly number of 16m driven piles and the steel is all cross linked. But do note that for a pukka LPS (lightning protection system) you may be looking at large earth mats or an array of rods to get the resistance low enough.

A lot of generalisations there. How did you calculate the 18,000 BTU size?

Shading your outdoor unit will help, make sure you don't restrict its airflow. Any shading you can give your walls will help too. We've had to shade our water tank as the "cold" water got too hot to shower

We've used several flavours of similar stuff both with and without the "decor". This one happens to be in-stock (it's actually conwood, same-same). For a shelf install it with the decorative side down so you get a nice flat surface.

220V +- 10% (which is sort of guaranteed) is 198V to 242V. In reality, even your non-inverter A/C should be fine down to 185V (-16%). Small AVR (automatic voltage regulator) are readily available which will magic 220V out of 150V, cover just one or two items or your whole house. Pretty well every A/C in Delhi has an AVR next to the indoor unit, power there can be somewhat "variable".

Go on the first day they re-open and you'll be fine, it will be BUSY. In future don't leave it to the last minute, your extension will start from the current permit to stay end date.

Thaiwatsadu, Global house, MegaHome have air-terminals, rods and copper strip in varying combinations, you'll likely end up visiting all three to get what you want. As to whether they actually work? Even now the jury is out on just how to protect your installation. Peruse the many manufacturer's websites and advice notes and make an informed decision. Not long after we moved in, we took a direct hit to the roof of our steel and concrete home. Frightened the willies out of the wife. Physical damage was a chunk out of one of our teak barge-boards and a couple of ridge tiles. Easy fix. Our roof steel is (fortuitously) connected all the way down to the steel in the piles which doubtless limited the damage. Electrical damage. Pretty much everything outside the faraday-cage of the house got zapped, satellite LNB, WiMax router, electric gate controller etc. Inside damage was limited to PC UPSs. Lights and TVs etc. lived to tell the tale and at the time we had no surge suppression. We still haven't installed any air-terminals although we have surge arrestors everywhere. No issue in 10 years (looking for wood to touch!).
