As you state, the current tax free exemption for gifts is THB 10 million, but that is for gifts between people who are not related. For gifts to close relatives and spouses, the tax free exemption is THB 20 million. For inheritances, there is a tax free exemption of THB 100 million. Inheritances between spouses are exempt from tax irrespective of the value of the estate.

I doubt you would be able to get that information over the phone, however you might be able to find the valuation on this website: https://landsmaps.dol.go.th/ Not all land parcels have a valuation registered on the site, though.

Thanks for the explanation. I will have no load between inverter and the CT, in fact the nearest load is 50m from the inverter location so it would be way after the CT. Given that, I think I will go with the "Zero Export To Load" setting. I will probably install the CT even if it is not needed, just in case I change my mind in the future (or if I for some reason would want to run my meter backwards, in which case I believe the CT is necessary).

Thanks for the reply. So for my setup, it doesn't really make any difference whether I select "Zero Export To Load" or "Zero Export To CT", other than I don't have to install the CT for the former setting? Any advantages in selecting one setting over the other? Keep in mind, that for 80% of the year when the sun is plentiful, I plan to have the breaker open between grid and inverter (so I will in reality be off grid). I do this partly to provide a little added protection from lightning surges coming over the incoming lines, but also because I have learned from other threads, that the Deye inverter have some ghost import/export even when set to zero export. I want to avoid this as much as possible.

Does it matter if I set the inverter to "Zero Export To Load" or "Zero Export To CT"? I don't have a backup load, or to be more precise my whole house is the backup load. So my wiring will be like this: In both modes the inverter will provide power to the backup load, and will not export power to the grid. This is how I want it to work. However, I note that only under the "Zero Export To CT" mode does it say, that if PV and battery is insufficient to power the load, then the inverter will supplement with power from the grid. What happens under "Zero Export To Load" if my house draws more power than is available from PV + batteries?

It sounds like you closed the fixed deposit account prematurely. The 469.72 is the interest you would have received had the deposit been fully matured. The 366.97 is returned interest because the account was closed prematurely. Net interest is 469.72 - 366.97 = 102.75 and 15% tax on that net interest is 15.41.

Because of the location I will not have the inverter connected to WIFI, so if I want to see data/status I have to physically go down to my equipment. So seeing the batteries parameters in the inverter doesn't really give me any benefit, I can just check the batteries directly. There is one place in the house that I am able to pick up the bluetooth from my DIY battery pack, but not from my Liyuan pack.

What is the reasoning for this?

I have no idea. I have two 280aH batteries connected in parallel without communication with the inverter, everything is controlled by voltage. One of my packs is a DIY job, while the other is the same Liyuan battery (with JK BMS) that you have. If the Deye inverter doesn't work without communication established, can I just connect the communication cable between the inverter and the Liyuan battery pack?

Another thing from the Deye manual, that I don't understand: This is something I haven't seen when watching people installing solar (professional or DIY). What's the purpose of wrapping the battery cable and BMS communication cable around a magnetic ring? The recommended cable size for the battery is 95-120 sq.mm. (for the 10KW and 12KW inverter respectively). I would imagine trying to wrap a 120 sq.mm. cable two times around a magnetic ring could prove quite a challenge). I am a bit worried that the Deye inverter won't work with my existing batteries, I am hoping that it is not an absolute requirement that communication is established between inverter and battery.

I do have MCB's between the panels and the inverter in the current set-up, so am able to turn them off when I want to. But my current inverter only have inputs for two MPPTs, so two strings are connected in parallel. The Deye inverter has three sets of inputs, so by running each of the three strings through one of those "combiner" boxes into a separate MPPT on the inverter I could optimize the production from each string. It would also free up space in my existing CU, as I would no longer need the MCBs to be in there.

The incoming supply to the house is buried underground, so connecting the two earths would mean digging up the NYY cable and run a wire between the two earths. Not really something I want to do if I can avoid it. With regards to the PV panel surge arresters, I was thinking of running each of the three strings through one of these so-called "combiner" boxes: If I were to do that, what MCB amperage should I go for? My current panels have open circuit amperages of 8.79 to 10.12A, but I would like to have the flexibility to easily connect future panels with different specs (maybe even connect two strings in parallel). Would 25A be a reasonable compromise between safety and flexibility?

Sorry, I'm not sure I understand what you are saying. You have the load and grid connection earths connected with your house earth, as well as connection between the house and inverter earth? Because of the distance (50m), I won't be able to do that. My current setup, and what I am planning to continue with the new Deye inverter, is to connect both the inverter metal enclosure as well as the load and grid earths to a local earth rod (I think you have earlier called this a TT island). Only live and neutral will run between inverter and the house wiring. Will wiring the Deye inverter like that work OK and be safe? Thanks for you reply.

It would be very much appreciated, if anyone has a reply to my question (in my post from Wednesday) about how to wire up the inverter? @Crossy? Before I buy, I want to make sure that it will actually work for me.

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).
