OK children. Let's play nicely, shall we? There's a big-bad Teacher Mod watching Our OP got his answer a while back, the "close" button is on screen.

Currently we are at about 230k Baht.

Time for that nice, new, inverter A/C (yes, they do make a visible difference) ????

Yeah, we actually use about 30-35kWh per day, but this makes a bit of a difference

I await our 19/12 bill with bated breath ???? Current prediction (if the weather plays ball) is for about 200kWh.

U got a link for that, I thought it was only for 3 months (I would love to be proven wrong).

There's a thread somewhere that details the FT discounts, sorry I'm not going looking for it (IIRC it was in the News forum). Google Translate on your phone CAN read Thai and gives quite good results on energy bills. Our bills that were printed on 18/09, 19/10 and 18/11 show the FT discount as a -ve amount under the FT charge. The discount is almost 1 Baht per unit if usage is below 300kWh, a sliding scale between 300 and 500kWh usage and no discount over 500kWh usage. Our last bill (printed on 18/11) for 114kWh usage shows an FT charge of 106.51 Baht, immediately followed by the rebate of 104.93 Baht. The bill printed on 19/10 for 303kWh shows an FT charge of 283.09 Baht, followed by the rebate of 156.05 Baht (just missed the full rebate by 3kWh ???? ).

It's pure speculation on my part, but I would suspect anything much over 400 units exported from a 3kW system in a month (that would mean no local usage) MIGHT trigger an alarm somewhere. Like you we'll stick with the "unofficial" net metering (and get 1:1 $$$) and expand our storage should an electronic/no-reverse meter come a calling.

IIRC discounts are for bills printed in September, October and November.

Thing is, what happens when your "3kW" system starts blasting 9kW into the grid? The authorities here are not totally stupid, despite appearances sometimes.

Yeah, definitely tempting despite being Li-ion.

Of course;- Order your cells here https://www.alibaba.com/product-detail/Luyuan-8pcs-280AH-LiFePO4-LFP-3_1600066769898.html?spm=a2700.shop_index.89.1.7db6273e83n0Uy You need to order 2 (16 cells). And the DIY kit here https://www.seplos.com/sale-21924968-mason-diy-unit-suitable-eve-280ah-cell-box-stack-type-without-cells.html And make this ????

Ouch! I can build a 280Ah 48V (13.4kWh) pack using grade A cells and a DIY kit from Seplos for about 2,500USD (95k Baht) and keep the other half million in the bank ???? OK the Powerwall does include a 10kW inverter and the management hardware, so add another 50k ????

Moving on from my earlier comments Shenzen Luyuan are very well regarded on other solar forums and they definitely supply new cells. https://szluyuan.en.alibaba.com/ I've not bought from them personally, but I've not heard any negative reports.

This ^^^ if billed direct from PEA, if you get your bill via a landlord, it could be rather more. But, there's a potential (possibly large) increase in the pipeline for January ????

There's even an App to point you in the right direction https://play.google.com/store/apps/details?id=esrith.nbtc.dtv&hl=en&gl=US I have the .APK for an earlier version if that one won't load for you.

In a similar vein the Moro Islamic Liberation Front https://en.wikipedia.org/wiki/Moro_Islamic_Liberation_Front often wonder why they are on page 3,000 of a Google search ...

Is this antique box for digital terrestrial (has a TV-type antenna) or for satellite free-to-view (has a dish)? I'd certainly be looking at digital terrestrial now, the boxes are much of a muchness https://www.lazada.co.th/products/hd-tv-digital-dvb-t2-hdmi-wi-fi-i4037667360-s16124794837.html New TVs have digital tuners built-in, could be time to treat yourself ???? If your existing box is digital terrestrial maybe just a re-alignment of the antenna is all that's needed ????

I agree with your sentiments on Li-ion although if they are in a fireproof home away from your house and vehicles there's not really that much risk. Buying cells on-line is a nightmare, there are far too many sellers with "new" cells that are really used, at least we knew that our cells were used and sold as such. I've also bought 32650 cells from one seller and had good experiences only to buy some more from the same seller and got junk. There are known good sellers on AliBaba / AliExpress but for best results you need to look at the dedicated solar energy forums, we really have too small a footprint here to maintain accurate and up to the second data. Our cells live in a well shaded home, we don't push them really hard so battery temperatures rarely climb above ambient.

Never had that problem with the stuff we buy, but it comes from a local burner who uses forestry thinnings and traditional (ok, oil-drum) burners.

What he said ^^^. The solar installers know they have you over a barrel so they can bump up their costs, expect equipment and accessories to be 40 - 45% of the total installed cost. And yes, they do have to be actual registered contractors, you can't DIY "to code" and get approval, I asked! LiFePO4 batteries are significantly more long-lived than lead-acid and keeping them in the 20-80% charge range should put them well into the 8,000 cycles (22 years' worth) bracket before they lose a significant amount of capacity.

Yup, exactly what we use to get the barbie charcoal going. And, of course, it doesn't leave that diesel or rubbery taste (which takes a surprisingly long time to burn off).
