Does the shiny digital meter phone home, or do they still need to read it the old fashioned way?
I don't know what this particular one do but I found the original Chines mfgr when googling for a users manual of it.
Mfgr specifies that it can be fitted with one or more different type of interfaces as 433MHz RF, optical. wifi, mobile broadband, modbus. rs-485 among others.
Mine have what looks like an infrared diod in its round window.

Can you please share some photos of how you fixed the panels to your roof
No photos, company I bought the panels from did the install, I'm too old to enter the roof.
Roof was once covered by leaf tiles (temple type tiles) so it has 1"x1" horizontal metal beams every 10 cm from top to bottom, the tiles were replaced by OSB board and shingle a few years ago.
The guys mounting the panels understood the 10 cm distance between the beams and screwed solar panel mounting rails through OSB board into the beams. I've been up in the attic a couple of times to check for leaks and haven't seen any.

How long before you need a new 280,000 Battery ? How long before it's efficiency starts to deteriorate ? Thanks.
The battery is rated for > 6000 full discharge + charge cycles , I don't do full discharges so I estimate that I do the equivalent of ~200/year.
With a pessimistic calculation they should last at least 10 years, optimistically 20 years.
My system is not only intended for saving on the PEA bill, I live along a road with frequent power cuts due to high-voltage fuse blown.
When worst it is a couple of cuts per day for a week after which we are down to normal which is once per week or two week and this has been ongoing for more than 20 years.
Those cuts lasts for a couple of hours until the PEA fuse-swap-monkey has dragged his lazy legs out of bed.
Then we have the cruise ships anchoring on the sea cable from the mainland and that will surely happen again now with a new cruise ship terminal being built and a doubling of arriving ships.
So, in myself I trust, in PEA Samui I distrust. Self sufficiency in electricity and water (have own well) is a must here.

32 x 445W Longi panels installed by company 200.000 baht
Do-it-myself:
Deye inverter imported from China 96.000 baht
40 KWh ESS battery imported from China 280.000 baht
Various install material 20.000 baht
Total 600.000 baht, reduced PEA bills of 90.000++ baht/year so 6.5 years until ROI.

I've been wondering for some time when someone at PEA will react to our drastically reduced power consumption since end of May last year when I first started to use solar power.
We have always had our meter read in the morning of the 20th during the 22 years we have lived here and the only exception to that has been them reading it one day earlier if the 20th was a public holiday.
That changed in February when they came the 19th even though the 20th wasn't a holiday and then in March they came even earlier, the 18th. 🙂 so I suspected that something was in the doing.I have not exported much to the grid this year, only around 20 units/month but not close to the dates the meter reader has been here so I'm quite sure that he has not seen a reverse spinning meter.
The bill for April was an empty one with all lines x:ed over, not even listing the 17 units we had used so I was not surprised yesterday when I found that they had replaced the meter.- 1

Ordered April 14th from Qishou Shenzen as DDP and it arrived in Koh Samui today.
I have an empty Seplos Mason 280 DIY chassis to put them in.
The cells are EVE MB30 which are rated for 306Ah but in reality can deliver 330Ah and they are rated for 10000 recharge cycles. Flexible busbars and isolation sheets were included.
Total price was $1168 + $289 for the freight or $90.5/cell at my doorstep, the Seplos chassis was around $500 earlier this year so $2000 for around 16KWh of ESS.

Again, the date they want is in the box on the left, which is the date of the next 90-day report.
No it is not and by saying that you also say that the 90 day report is a visa.
The date they want is the date in your passport of the "Permission to stay until" stamp.
STAY visa is the keyword. There is nothing from a 90-day report receipt that you need to fill in when you do a new one.

visa expires is the date in the box on the paper clipped in your passport from the last 90 day report.
There is no visa expires date on the 90 day report receipt you get after doing an online report.

No it is not.
A 90 day report is not a visa, the date is the expiry date of stay and it clearly says so.

On the paper you print off to put in your passport, in the oblong box to the left is the date of your next report, this is the date you use on your next online 90 day report...
You have obviously never done a TM47 90-day report online.
You are asked for 2 dates, "Arrival Thailand Date" and "Stay visa expires" , the latter being the date your "permitted to stay until" stamp in your passport indicates.

Update: Temp coming down again.. after tightening the 2 screws.
They will loosen up again, sorry to be repetitive but you are using a flat lug that will have a very limited contact surface with the switch.
It doesn't bottom out so the pressure on it will deform its side edges with time and that is when it get loose again.
Don't ask me how I know this..

IMPORTANT NOTE: - Please don't lose sight of the fact that there is a LOT of energy tied up in your battery packs.
These packs are quite capable of pushing several thousand amps if shorted, that 1/2" drive ratchet stands no chance
My way of doing it in the battery room under the house.
50sqmm feed, switch, 35sqmmx2 to the250A fuse and the busbars.
Two battery stacks of each 4x5KWh (=40KWh) connected to the busbars.

Looks like you are using some kind of lug on the wires, maybe DZ47/C45 lugs like this:
the switch however is intended for bare wire which you can see from its rounded bottom.
I use DIN-rail enclosures for all my other switches but the battery DC switch I used is this one:
it has proper M8 hex bolts and not weak Philips type screws..

Yes Schwab reimburses, but I find the cash advance most convenient and can get large sums of money rather than withdrawing many many times from the ATM machine
Maybe you could do a one-time exception to your rule just for test purpose?

Unfortunately that SIM card will expire in 1 week (18 april), so I am looking for a new 1-year dTac unlimited download SIM.
Some 1-year dTac cards does not have to expire, you can fill them up at a dTac shop for another year.

Elon should have built his mega-battery in Grünheide instead of building it in Australia.

That means that you can temporarily overload your meter up to 50++ Amp somewhere above that your fuse will trip but your meter could withstand up to 100A (before it heats up so much that it starts to spin slower ☺️ )
-
A 15/45A single phase meter can withstand 15A continuously and 45A for a short time, not 45A continuously!
The same goes for a 30/100A 3-phase meter, it is 30A per phase continuously.

Interesting to see that I'm not the only one to have a consumption peak 31/3, our daily consumption during March was 52KWh ± 3KWh with 0.5KWh daily purchase from the grid (because current transformers in wrong place) and no feed-back to grid.
31/3 we had the record consumption of 68.4KWh and we had to buy 6KWh, I'll have to rectify that purchase today 😁

We got a shiny new digital meter

A lot of crap is manufactured in China mainly by smaller companies but there is also a lot of good products from companies with a name to defend.
I get a deja-vue feeling when people believe that everything Chinese is substandard, it reminds me of the 60's and the Japanese handheld plastic transistor radios and how we made fun of Japan then.
