A story from a sensationalistic newspaper like the Daily Mail isn't worth the paper it is printed on. Can be true or can be invented, the latter being more likely.

Stunning view you have there! Where in Thailand is that?

There is a difference in price of around 54000 baht, a bit of that towards a couple of strong Thai men wont fix it? A good electrician should be able to dismantle a LVTopSun 15KWh battery into a 20kg box and 16 batteries of 5.5Kg per piece and then put it together again.

I would probably replace the 6x415 panels with 6x550 to get more power for the day when PEA switches your meter to a digital one. I would then install a small battery to cover the nightly consumption but not until you get a digital meter. 4 of the old panels can be used for the washroom.

Some parts are way overpriced.. Deye 10KW 1-phase 75000 + VAT = 80250 can be had from shopee for 69000 Combiner box 15900 ouch ! A PV only combiner box is 2500-3000 and the AC breaker and surge protector is no more than 500 baht. Still, they should not mix high voltage DC and AC in the same box! Batteries 165000 + VAT 11500, you can get 2x15KW LVTopSun from Shopee for 122000 baht. Same physical dimension but only 2 battery packs. Permit? You only need a permit to change the house structure if you mount the panels on your roof and you get that from the tessaban/amphoer. Doesn't cost 15900 + VAT.. You also need to tell PEA that you are installing solar but you don't need their permit to do it. They may come and inspect your install but it is without cost for you.

It is quite the opposite, no way Thai authorities would oppose an extradition when requested by China.

It is the simplest way to know how much excess energy you have which then can be diverted, their eddi for controlled making of hot water works in the same way. Home Assistant knows how much excess energy you have but there is no way to communicate that to zappi or eddi that I know of.

It is a Deye and I did previously have grid charging enabled for Time 1 but that was when we had lots of grid cuts. That to make sure that I started midnight with not less than 28% SOC which would take me through the night without power cuts. The screenshot is from the Solarman remote monitoring and configuration program.

Yes. Continue a bit further down is section 5.7 to "Time of use". Time of use when activated controls charging/discharging when grid power is present. The setting takes precedence over the battery setting in section 5.6. I have the battery setting in 5.6 at 10% deepest discharge but at 20% between 4 am to 8 am in time of use. If battery goes down to 20% when grid is active then grid will take over, if grid is inactive then I have another 10% until the inverter stops producing from battery. You can also charge the battery from the grid at a certain time based on the SOC setting in Time of use.

It is possible, the EPS output from a Deye inverter can supply your whole house if you want, not only the essential consumers. It can supply up to the limit of the inverter (in your case 10KW) from PV and/or battery and if you don't have enough power from PV and or battery then it will take the missing part from the grid through Deye's grid connector (grid-assist). You will not even need a CT if you run everything on the EPS output, there is a setting for it: "Zero Export To Load: Hybrid inverter will only provide power to the backup load connected. The hybrid inverter will neither provide power to the home load nor sell power to grid. The built-in CT will detect power flowing back to the grid and will reduce the power of the inverter only to supply the local load and charge the battery."

It is correct that you will need a CT to protect from export into the grid through the AVR which most likely won't like power flowing through it in opposite direction to which it normally operates. Most inverters do have a UPS/EPS output for emergency light and equipment and that is the only active output from battery and PV when grid is not present. The inverters grid connection follows the frequency and voltage of the grid and will become inactive (island mode) when grid isn't present. What brand of inverter did Thai Solar System quote to you? In general I'd say by looking at the picture that this is a very "el cheapo" Thai system. A PV combiner box combines 2 or more strings and contains fuses, breakers, and over voltage protection, that is the upper part of the box in your picture. I would never mix DC (PV or Batt) and AC (grid) in the same box! If the installer has to put everything in one box in order to keep the price down or his profit up then I would go somewhere else. Using lead-acid batteries is also a sign of made in Thailand for Thais..

Not generally but one of the inverters they package together with their batteries is a Deye rebrand, the others are not. LVTopSun's main product is ESS for solar.

It was more like Trump: I'm hungry, mouth is open. Hand over your beef and stay out of my hose.
