  1. Peak output, possibly https://en.wikipedia.org/wiki/Supercapacitor

    If you mean running multiple inverters in parallel, yes, provided the inverters are designed to work that way.

    It's also possible to use a small pure-sine inverter to trick a grid-tie inverter into starting up and supplying power (Google AC-coupled solar), handy to get things going if the grid is off and the sun is shining.

    I'm guessing all a grid-tie inverter needs to see is an AC waveform within it's own operating frequency range? I can't imagine anti-islanding works by looking at voltage, otherwise you'd never be able to have parallel grid-tie inverters.

  2. My setup with Crossy's cheap eBay changeover switch goes in this weekend smile.png

    In my case, the generator needs to remain portable, so it interfaces via 32A 2P+E plugs and sockets.

    This all went in on Saturday as planned, and I'm happy to report it works just fine ;)

    I now have 2x AC's, 3x fridges, and lights/fans able to run off my 5.5kva genset - thanks Crossy! ;)

  3. In the end I bought a bunch of the boxes pictured in my last post for about 300 Baht/ea.

    Things I've learnt already:

    1. My pool pump & chlorinator, which are spec'd to draw 810W actually only draw 690W, and that only increases to ~700W when it's time to backwash the filter.

    2. My main house pump which is a 750W inverter, draws up 1200W (!)

    3. These energy meters also have non-volatile memory (they do not lose numbers when without power), so in the end they're just as useful as something more advanced, I just need to keep some spreadsheets ;)

  4. After I check Daikin specs, it seems FTKM is for the inside unit and RKM is for the compressor. Seems a bit strange to me but maybe that's the way it is. Anyway... the unit is installed and working as advertised. Well, except there is nothing on the unit or the manual (Ok it's in Thai) that says it's SMART or SMILE or like that. Still searching.

    There should be a label on the bottom of the indoor unit with the FTKM.... model number. The outdoor unit should replace the "FTKM" prefix with "RKM" but the rest of the model number should match the indoor unit.

    e.g. FTKM33NV2S (indoor) RKM33NV2S (outdoor)

  5. The PEA say they are going to do it... But when it'll get done, who knows.

    Said there's no way for any contribution or even full payment to speed things up as it's non-private so just have to follow their procedure.

    How best to wire in a stabiliser? (I have a SafeTcut CU with RCBO.) Only stabiliser available local are these Chinese rebrands:

    The stabilizer goes between the meter and the CU.

    I just looked up some prices, and it seems the 15kva model is only a couple of thousand more than the 10kva one, so maybe that's a better idea as it could run your water heaters as well?

  6. Just had the sticker on the prop shaft come loose. It's common and Luckily I had seen this on the Everest Thailand facebook site and seen a video of the noise it makes. It's a pain in the butt to get to. Burnt my arm on the silencer box lying on a gas station forecourt. Had to Jack the car to get underneath to get a hold of it. Would recommend removing it as its a right pain if it goes on the road.

    Picture attached of offending sticker. My Ev has 14000 kms on it.

    So last night I pulled this sticker off as "preventative maintenance". There goes my "crap if dropped" jokes. I think mine was one that wasn't going to come off though, because wow was it hard to remove!

  7. Sounds like in that office I will have to ask the desk to part with its attachment to the wall.

    The other office I have no idea how I can work em.

    I suppose wall mounted brackets with extension arms are a bad, bad idea??

    I use wall brackets for my 4x surround-height speakers:

    post-163537-0-46503500-1463107354_thumb.

    I haven't tried this at ear level or for mains, but I have no reason to suspect it wouldn't work.

    I got these brackets off eBay, after the two local suppliers I found both came back to me to say "no have".

  8. Hearing about these discounts is bugging me. Why? Well... Hiccup No.1 - Despite paying a 5000 baht deposit to hold a promotion the dealer now phones to say the promotion ended and no longer can give 50000 baht off retail price. £1000. This after finance accepted and car ready for collection. Mazda dealer looking like cowboys, idiots or both. Will be having words with them. If I take the car all the free accessories better be present and if they don't give the promotion and I still want the car I will be smiling when I demand this month's new promotion and demand this month's 7000 baht lower retail price. Car better be absolutely spotless though or walking away with my 5000 baht deposit... but now sounds like they are trying to pull a fast one and remove the discount as know they have a sell. Pickup waiting to be collected. Guy called 15:00 to state car ready. Finance only accepted day before. Then 18:30 calls again. Outside office hours... to say promotion ended and 50000 discount not available. Amnat Charoen Dealer BTW.

    When you made the booking, were all the terms of the deal written down on the booking form?

  9. You know you have at least one phase that's low voltage - have you tested the other 2? If they also have the same problem, going to a 3 phase system isn't fixing anything. If you do test and find that one or both of the other phases are OK, just get a sparky to hook your meter up to one of the more healthy ones.

    If all phases are low, or likely to be so, just get a single phase voltage stabilizer and suck up an extra 5% or so on your monthly bill ;)

  10. Cheers for that.

    I think I'm going to have to re-work things in the office. The desk/shelves are fixed to the wall. So I have to leave the speakers as are, or perhaps think about placing them behind me at the other end of the room - about 5-6 metres. I do kinda like em up close though.

    The other office is much worse - narrow fixed shelving on walls - they would have to go sides to the wall, probably 1.5 metres behind me, 5m apart, with me off-centre.

    Off centre listening is not a problem - you can stand right in front of one of them and still hear a stereo image. Heck you can stand against a side wall and still hear a stereo image wink.png These things have a very wide sweetspot. Speakers behind you is a worry though - you're not going to hear them at their best with your back to them sad.png

  11. The biggest benefit of the Michelin inflator is it's size - it's tiny - so can be stowed in the car easily. The second benefit is it's speed - it's more than twice as fast as other inflators I've tried/own. Lastly, the programmable stop point, with accurate pressure metering, means no more sitting next to your car for minutes while the tires inflate wink.png You'll hear it cycle on-off a few times when it hits the target pressure, so you know when it's just about done too.

    Only downside? It can't de-inflate tires to a preset pressure. That would be useful for those times when you've gone to max. pressure for a heavy load, or want to deflate tires for driving on sand etc.

    For Everest owners, note that it fits in the cubby holes under the trunk floor perfectly. None of my other inflators come close to fitting. It also has a soft bag, so it doesn't rattle when stowed either.

  12. I have recently fit a 5 stage filter to my water supply, it looks the same as the cascade, but under another brand name. I fitted it about a month ago but have noticed the white primary filter becoming very yellow.

    If it's plumbed correctly, the primary filter should be your sediment cartridge. If this is a ceramic one, it can be cleaned a few times before it needs replacing. Yellowing indicates your supply water isn't too clean.

    Has anyone heard of a water company called Lux, they called yesterday selling these filters, aparrantly the sand in them comes from the Netherlands. My water supply was extremely dirty, so we went ahead and had it installed. The guy that fitted it showed me samples of water before and after, in the before the water was green and even had some sort of leech in it, the after was pristine. We have one months 'free trial' and pay 3000 baht the first month and then 1000+ baht for 11 months. Does this seem a fair price? Sorry about the image being on its side, but no matter what I do it still comes out that way.

    This is the same basic concept as what I use - mine is just a little bigger. So long as you remember to backwash it regularly enough (somewhere between daily and weekly depending on mains quality), it should keep on doing a good job for years to come. 14K Baht all up over 11 months obviously more expensive than just buying it outright though.

    The only thing I added was a carbon filter after the sand filter - which needs replacing every 5-6 months.

    I bought a slightly smaller version than yours (about 4' tall) for my father's house (very light water usage) and it cost 6xxx Baht + extra for fittings/valves - but I fitted it as a DIY. I don't recall them claiming imported sand though wink.png

    Actually, on second thought, that one is probably also 4' tall ;)

  13. Let me put it this way:

    If i dont sprinkle it will be hotter inside.....right or not??

    It should cool down your attic, yes. How much effect it has on the rooms below solely depends on how good your insulation is.

    I can say that in my houses, it wouldn't do much - we get maybe only 2-3c of heat gain through the ceilings each day, and that's all happened by mid-afternoon anyway. We use ventilated soffits all the way around our house though, so as soon as there's any breeze, the attic is getting cooled naturally, and completely free.

  14. Again stubborn George. In my case water is no problem at all. Also groundwater. Sprinkling a roof for couple of hours thus no problem with my tiny pumps hehehe....see the thai vid posted by me for @gary before, page 28.

    If its working for a chicken shed why not for my tiny house?? Give me a good reason. Ofcourse it wont work like an aircon but if inside it will be cooler, why not give it a try.

    Attached pict screenprint sprinkler system thai vid page 28.

    If using ground water, just bear in mind that your roof might not look very pretty for long ;)
