Another example of why you have to be very careful what you use AI for:

No, definitely an inverter for a 48V battery. The supported battery voltage range is specified as 40-60V.

The wiring diagram in the Deye inverter manual have a local earth rod connected to the metal enclosure of the inverter, and the earths for the grid and load connections connected to the same earth rod as the house wiring: Alternative wiring example where the load earth is not connected: My equipment is 50 meters from the house, so for the current inverter both the metal enclosure as well as the grid and load earths are connected to a local earth rod (TT island?). The house wiring is connected to a second earth rod close to the house. Any problems connecting the Deye inverter the same way? It seems to me that the recommended battery cable size is a little over the top: For all other cable connections the size is specifically mentioned as being for copper wires, but for the battery the cable material isn't specified. Maybe it's supposed to be aluminium, but if so it would be nice if they mentioned that.

Not really. In most countries the income will already have been taxed at higher rates than used here in Thailand, so with the credit you get for the tax already paid no tax will be due in Thailand. Sure, there will be some expats for which this will result in extra tax, especially if they have income that is not taxed in their home country, but which is taxable in Thailand. But for the majority it will just cause extra paperwork. Most serious high earners are not living in Thailand anyway. Despite what some people here think, this move to tax foreign earned income is aimed at Thai people, not expats. We are just caught in the cross-fire.

Perhaps. However, they want to tax foreign income, but they also don't want to limit capital inflows to Thailand. The logical solution is to no longer link taxation to transfers and just tax worldwide income for all tax residents, irrespective of whether the income is transferred to Thailand or not. That's what most countries in the world do.

Yeah, I know the name is misleading but I don't actually want to combine anything. I would just use them for isolation of PV panels and for the surge and lightning protection.

My current inverter only have two inputs for PV panels, and as I have three strings, I have had to connect two of the strings in parallel. If I buy the Deye inverter above, I will change that and connect each string to it's own separate MPPT. I am considering running each PV string through one of these "combiner boxes" (I don't know why they call them combiner boxes, as nothing is combined): Box from Taxnele: Link: https://www.aliexpress.com/item/1005005960373005.html?spm=a2g0o.cart.0.0.37ae38dasnMqeb&mp=1&pdp_npi=5%40dis!USD!USD 27.91!USD 26.21!!USD 26.21!!!%40214100f417475456200213633ebc32!12000035605718499!ct!TH!754241718!!1!0 Another one from TomZN: Link: https://www.aliexpress.com/item/1005005242730785.html?spm=a2g0o.cart.0.0.37ae38dasnMqeb&mp=1&pdp_npi=5%40dis!USD!USD 32.30!USD 30.57!!USD 30.57!!!%40214100f417475456200213633ebc32!12000032472536403!ct!TH!754241718!!1!0 So, good idea or bad idea? If good idea, would you go with the Taxnele or TomZn box and why (or a third option, suggestions are welcome)? What current rating would you select (best combination of safety and future flexibility)? I like the input connectors on the TomZN box, it makes it easy to move things around in case of a malfunction.

No, I have no plans to run any smart functions.

So if I am reading your second graph correctly, you were pulling a load of 4-6 kW consistently for about six hours without problems, correct? My existing inverter doesn't seem to have problems when charging the batteries, it's when a high house load require the inverter to convert DC from the panels or battery to AC for the house. What would you guess is the highest consistent load your inverter has to deal with, for instance when charging your EV? (I also use a granny charger).

Yes, I would expect this inverter to be able to handle my load, and at the same time it would give me quite a lot of flexibility should I want to add more panels in the future or change the existing ones to others with different voltage/amperage characteristics. Where did you get that screen shot from, that seems like a pretty good price?

Yes, the fans are still working (and quit loud too), but I have not added any extra fans. The location of my equipment is right smack dab in the middle of termite and ant territory, and since the inverter is not sealed I expect critters to take up residence inside the inverter at some point in the future, so I don't want to add extra equipment to keep it cool. I'd rather change the inverter with a better sealed unit. The overheating doesn't really seem to be closely related to ambient temperature. It overheats even in the cool season if running constant high'ish loads for an extended period. And it's not consistent, sometimes it overheats and other times it doesn't running similar loads and at similar or higher temperatures.

I have a cheap Chinese PowMr 8.2kW inverter. It runs OK most of the time, and handles 5-6kW loads fine for a short period. However, if we run constant loads of 2.5-3kW or higher for two or three hours, then the inverter at some point overheats resulting in it derating or shutting down. I think it's time for a new, higher quality inverter. I was thinking about the Deye SUN-10K-SG02LP1-EU-AM3 inverter (I don't want to run two 5K inverters in parallel). Our absolute maximum load (when shower heater plus some other loads are running) is 6kW, and the maximum constant loads for extended time is around 3.5kW (when charging the EV). I would expect the Deye inverter to be able to handle that without any problems and without overheating. I can get this inverter on Lazada/Shopee for just under 70k baht. Before buying, however, I would like to hear the experiences of other board members who have Deye inverters. Have any of you had any problems with overheating/derating when running large'ish loads? Also, I have two battery packs with different inverters connected in parallel without communication between inverter and batteries. That works well for me. Can the Deye inverters support batteries without establishing communication between inverter and batteries, i.e. you just input charging voltage, at what voltage to switch over to grid etc. Thanks in advance for your input.

I would guess that at the time your local PEA ordered wires for their 5/15 meters, what was in stock was blue wire. Like-wise, when they ordered new wires for 15/45 meters, what was in stock at that time was black wires. Next time they run out and order new supplies, maybe it will be the other way around. What I am trying to say is, that I don't think we should make any assumptions on wire size based on colour.

Nope, new house so they came and installed the meter and the wires when our house was being built. And you can see from the pic that the blue wires are thicker than the black (which are 16 sq.mm. copper), so I am guessing that the blue wires are 25 sq.mm. aluminium. Why would the colour be indicative of the wire thickness, anyway?

We have a 15/45A meter with blue incoming wires.

For comparison, we just paid around 20k to have a torn ACL repaired for one of our dogs (although technically it's called CCL in dogs).

In Thailand you cannot move an account from one branch to another. The first three digits of the account number is the branch number, so the only way to "move" your account to a new branch is to open a new account (with a new account number) in the new branch.

I have filed every year since 2012, because I wanted to reclaim the tax withheld on interest on my bank deposits. I have been living off savings and haven't had any foreign income until 2022, when the first of my pensions started paying out. Since I didn't transfer any money to Thailand in 2022 and 2023, I haven't had any foreign income to include on my Thai tax return until 2024, and besides it wasn't until 2023 that the Thai government started talking about taxing foreign income transferred to Thailand. Until then it was always assumed that any transfers would be of savings from previous years, and the rules only allowed taxing of income transferred in the same year as it was earned.

Yes, I had assessable income in 2024 and included it on my PND90 filing. No, I didn't end up paying any tax, as my income is under the sum of deductions and exempt income that I am entitled to: THB 100,000 expenses deduction THB 60,000 personal allowance THB 60,000 spouse allowance First THB 150,000 of net taxable income is taxed at zero %. So a total of THB 370,000 that is not taxed. When I turn 65, which is when my main pensions start to pay out, I get an additional THB 190,000 deduction, but I am not quite there yet.

Two weeks ago I went to the local Revenue Department office here in Lamphun where I live. I showed the clerk/officer the document from the Revenue Department head office (pasted above in motdaeng's post), and explained to her that I wanted to file a tax return including my foreign pension. Unsurprisingly she had no idea how to do that, as they had received no guidance from Bangkok on the matter. Consequently, I was handed off to her boss who also knew nothing about this, but could see from the official document that I was in fact expected to file a tax return for my foreign pension. Over the next hour or so, I explained my circumstances (through translation by my wife) to the boss-lady, we looked at all my documentation and together managed to file my tax return electronically. Everything was conducted in a very cordial and service minded fashion. I have just checked my tax return online, and it has been accepted and finalized by whoever does the post-file processing. The problem people have had when trying to file their tax return, is that the provincial offices have received no guidance from Bangkok, and culturally when Thai people don't know how to handle a situation, they often revert to the "no need" response, even when that is not true. Some people here ask, why on earth anyone would voluntarily go to the Revenue Department and file a tax return. Everyone's situation is different, but personally I have several reasons for filing: Firstly, living in a foreign country where I have no absolute right to live, I try to do things by the book, which includes filing a tax return when i am obligated to do so. I don't want any risk of being accused of tax evasion (however small that risk might be) and jeopardize my future here. Especially since I don't actually have to pay any tax on my pension. The tax I pay at source is far more than any tax Thailand would potentially be entitled to, and I would get a credit for the tax paid at source. Secondly, I am entitled to claim back the 15% withholding tax on my bank interest. It is not a fortune, but I still want it back. It's a nice little bonus to get the annual check from the Revenue Department. Thirdly, avoiding having to file a tax return in Thailand by not transferring your foreign income, or simply ignoring the obligation to file for income you have transferred, could be counterproductive. The new tax rules say that any assessable foreign income earned in 2024 and later, becomes taxable in Thailand in the tax year you transfer the money to Thailand. So you have a potential future tax burden hanging over you by not transferring the income. By filing a tax return for that income, you clear that potential future tax burden. And because of the progressive nature of the Thai tax system, and the quite generous annual deductions, it's generally better to get the taxes out of the way annually, than to wait and combine income from several years into the same transfer. Example: A fictional foreigner (65 years old) living in Thailand, has an annual foreign pension of THB 1 million and pays tax in his home country to the tune of THB 100k. The double taxation agreement between his home country and Thailand allows both countries to tax that pension. In scenario one, this fictional foreigner transferred the full amount of the pension to Thailand in 2024, and will do the same in the future. Tax in Thailand on a pension of THB 1 million is THB 50k, but because he will receive credit for the tax paid in his home country, he doesn't actually have to pay any tax in Thailand. In scenario 2, the same person decided not to transfer any money to Thailand in 2024, because he first wanted to see how things developed. However, in 2025 he for whatever reason wants/needs to transfer his pension from both 2024 and 2025 to Thailand. Because he transfers the money in 2025, the income becomes taxable in Thailand in 2025. Tax in Thailand on THB 2 million is THB 277,500, from which he can deduct the tax he paid in his home country in 2024 and 2025. That still leaves him having to pay THB 77,500 in Thailand. But as i said, everyone's circumstances and reasoning is different, these are just the reasons why I have decided to file. You do you, and I will do me.

These devices have their uses. We use them when we take our dogs to the vet, as we lay down the back rest of the rear seats to give enough room for the dogs. When the dogs stand/lay on the back rest, it puts enough pressure on the seat base to set off the seat belt alarm. We also use them when buying dog food, 80 kg of dry food on the back seat is more than enough to set off the alarm. Obviously, we don't use them when people are actually sitting in the seats.

Is that your photo, and if so when was it taken? The sample dates on the sign are from 2013, which leads me to suspect that it was a photo taken before they changed the rules to allow reporting up until the due date.

Try reading his comment again. He wasn't accusing you, on the contrary he was defending you against those thinking you might have unsavory motives. Before flying off the handle, it would be a good idea if you read peoples replies slowly and understand what was being said.
