Reading between the lines (and I may be misinterpreting what you wrote), it sounds like you: Moved into your place in Bangkok, and your landlord filed the required TM30. You subsequently obtained an extension using an agent. The agent have contacts in Chonburi, so they moved your address to Chonburi to get the extension. You now try to file a TM47 in Bangkok, which obviously is not going to work, since your official address is in Chonburi. In order to file the TM47, your landlord need to register, that "you moved back to Bangkok". Your landlord not unreasonably reluctant to do this, as from his point of view, you never moved away. If I am correct in the above assumptions, then the only way to get your TM47 done, is for you to persuade your landlord to update the TM30 (monetary incentive?). Immigration in Bangkok is correctly refusing to file the TM47, until your address has been updated via a TM30. I am afraid this is just one of the complications with cutting corners and using an agent to get your extension. Immigration have no problems with you moving between provinces, but it is a legal requirement to file a new TM30 every time you move.

I received this reply from Deye customer service:

There is a separate battery temperature sensor included, with a (as you suggest) much longer wire. I have asked Deye customer service what this little thing is for. It was quite the task for a solo installer (me) to lift the inverter into place, especially since there is a battery pack in the way that I had to lean in over. Not to mention that I cannot quite stand upright where the equipment is. I went from a PowMr 8.2 kW inverter weighing 14.2 kg, to the Deye 10 kW inverter weighing 35.6 kg. Hopefully this increase in weight is reflected in a similar increase in quality, especially in the inverters ability to keep cool and not overheat.

No everything looked factory sealed. Here is a (hopefully) better picture: It looks like there is some kind of small device at the end of the wire. Could it be some kind of sensor/wireless communication device (I have no idea how small a BT transmitter can be).

Sorry, I don't understand. How/where would a 10 cm piece of communications cable be connected to achieve communication with the BMS?

What's this little doohickey for? It's not mentioned in the user guide's list of things you will receive with the inverter.

I decided to go for the Deye SUN-10K-SG02LP1-EU-AM3 inverter, so I ordered it on Shopee during the the 6.6. sale. The inverter was delivered about a week later, however they delivered the wrong model i.e. the SUN-10K-SG05LP1-EU. This model has inferior specs, most important for me was that it only has two MPPTs whereas the model I ordered have three. Return and refund went smoothly, the inverter was picked up on the same day as it was delivered and despite initially stating about two weeks for the refund to be completed, the money was in my account three days later. So I ordered another inverter on Shopee, this time from another shop. The new inverter (correct model) was delivered Wednesday by sellers own fleet, so I have been preparing for the install over these last two days. However, it turned out that was not the end of my shopping experience. An hour ago we received a call that they would deliver my inverter today with nothing to pay. This time the delivery was done by a transport company, but the inverter came from the same (second) seller as the inverter I received Wednesday. So it seems they decided to have an impromptu and unannounced "buy one get one free" sale. Obviously, we told the delivery guy that we already received the inverter, so he took it back with him .

I bought one of these MCCBs (200A version), primarily to function as an isolation switch: At a cost of 650 baht it was only a couple of hundred baht more than a similarly rated MCB. When it arrived I was quite surprised by the size and weight of the device, it has some serious heft to it weighing in at almost 1.3 kg.

The SPD does have an earthing symbol, to indicate that it has to be connected to earth.

What's the purpose of this little earth block in the "combiner" boxes? The block is connected with the SPD with a rather thin earth wire. I was planning on connecting my earth directly to the SPD with a thicker wire, but maybe there is a good reason for the earth block.

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.

It's only for businesses, ordinary people are not allowed to visit.

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).
