At least in Thailand I think the MEA does a decent job of buying back solar produced electricity at 2.2 Baht. other countries they only give you credits, not cash. I've been interested to build a solar farm here on some of our lands. looking for something like a 50kW system under 1MB. Anyone here in the forum had experience at this level?

The European Sealion 7 vs the Thai version has differences: - 91.3 kWh battery, vs 82 kWh on Thai model - 800V system vs 400V - DC Fast charge: 230kW vs 150kW I think the Thai version being priced right is already quite good. the RWD at 1.1Mb is a bargain, if the car doesn't have flaws and issues.

yep, I know, I know... 😄 I'm also a Computer Engineer, did in Thailand. However one thing: even we know that at 800V you need half the current used for 400V, the cables still need to support 400V at high currents. What you said is also true for power transmission lines. the 220V you get in the outlet has been stepped down multiple times, typically down from between 2kV and 33kV, the really high power lines are at 69kV or 115kV, even up to 500kV, so that that can send power to whole towns. 800V is really nice thou, not many cars here are on that platform yet, even the BYD Sealion 7. The Sealion7 sold in Europe is on the 800V platform, and so it also costs more than the one sold here. you get 800V only on the top end cars like the Porshe Tycan and Xpeng

yep, there are losses in regen, and there are losses in acceleration with high current. high current => copper/heat losses in the wires. I wonder if anyone ever reviewed EV car wires gauge and quality, I'm sure the BYDs are inferior and thinner than the ones like in Tesla. To fast charge at 250kW, you need some crazy thick cables. New BYD firmware shows dynamic ranges, mike usually show 5-10% less than with previous firmware, I have bigger tires and go 100-120 often, living in the best province of Thailand 😄 (235/60) I get 16-18.0

No, it's a bug on BYD. stops at 99.9kW man... That 12.5 is really hard to reach with the atto3, I know it's possible with the Tesla model 3 to reach under 13.0 kWh/100kms. maybe the Dolphin standard range could... my actual usage was 18.5 kWh/100km 95% highway 90-110 km/h I get 15.0kWh only in the city.

This one I was referring to: https://www.linkedin.com/posts/jaruwin-intharat-9389b91a2_ev-hub-at-ptt-station-huahin-were-activity-7234167185605046273-4uqC https://www.facebook.com/story.php?story_fbid=10231465389230573&id=1013432379

Never stopped the car, charged while running it. I actually drove way more than 11.1 hours. Total trip was 14:00 hours (left home 5:30, arrived 19:20) I think BYD display didnt count charging time and the time wasted when PTT chargers all crashed and rebooted a few times. What was really impressive, was the PTT station with EV HUB in Hua hin, it had 8 Super fast DC chargers is a format that looks like the pump, under the big roof, next to the Gas stations. Best experience I ever had. Also saw many of the EV Trash trucks recharging, those are massive batteries, and they charge every day. Anyways, that was some really impressive engineering feat from PTT. If they continue doing this, my PTT stock will be happy 😄 There are 4 stations (2 cars per station), each station claimed to provide 180kW, that would mean 720kW or 1800 Amp total!! in the USA this is peanuts, but here, it's new. being 3Phase, still we are talking about 600Amp per phase. I used 148kWh for the 799km trip. Total: 152.6 kW Total - Losses: 148 kW There seems to be a 3-4% losses from the CCS2 DC fast charger and the final battery storage. this could be due to the copper losses (i²r) PTT Charger (Car display) 86.5kW (84.7kW) => 2.2kW losses 56.8kw (54.2kW) => 2.4kW losses

Took the Atto 3 for a loooong drive. Is that really a consumption bug? look like It can't go more than 99.9 kwh I spent about 650 baht at PTT only. not too bad, but could be cheaper... this trip is still half the cost of an eco car, and 1/3 of a large car.

They should send this car to Autobahn with a good driver.

Report Monk in Nonthaburi Brutally Assaulted Over Debt Dispute
brfsa2 replied to snoop1130's topic in Bangkok News
Monk got what he deserved. maybe not even enough, 12,000 baht worth of that drug is quite a lot. -
I see people saying engine breaking is bad because it heats up the transmission. To correct: True for CVT transmissions, they are they worst you can ever have. Not True for Diesels, with "real" transmission that can handle high torque, Engine breaking cools down the engine quite a lot and is necessary for Diesel. During low gear at high RPM without giving gas, the engine sucks in a a lot of cool air at high speed without combustion. Cooling down significantly the oil. Diesel works best at very high temperatures, the downside is that the oil burns faster. you can observe with an OBD2 adapter or similar dashboards. Sport Mode in the Fortuner models with 500NM also cools down the engine by injecting a lot more fuel at the same RPM, the Boost is so nice and you can really feel that crazy torque. You can say there is no need to ECU tune, just press the sport button.

Bangkok Offers Waste Collection Discounts for Sorting Food Scraps
brfsa2 replied to snoop1130's topic in Thailand News
This great! I used to neatly sort our house trash in the past 10 years. trash collectors in Bangkok always appreciated it. The organics went to the soil as food for the worms... Still doing that when in Bangkok. Here in the middle of nowhere, we just burn everything, including plastics. Cant give a damn anymore really, everyone in the village does the burning too. The collection from gov stopped years ago. So we just burn at night once or twice a week, everything, all plastics. at night is easier to hide, never got fined. Only the organic waste goes to the bushes in the backyard, food for the the water monitors around. -
Solar panel package suggestion.
brfsa2 replied to kwak250's topic in Alternative/Renewable Energy Forum
Nice! you can even wash it yourself. unfortunately my setup in Bangkok house has to be in the roof. It also helped a lot getting house 2nd floor cooler. Now, on my new house in the country side I will also do it in the roof but it will be a flat concrete roof, so I can wash it myself. still 2 years before the house is built. I am also considering potentially doing it on the Garage roof, I will have a detached garage and storage room on the side. Actually after I writing it, that makes even more sense now to put on garage. Let's see... -

no way I'd do it myself. even thou I have the full knowledge of it. I could definitely do it on a smaller scale if not on a modern house roof with 2 guys helping me. - If you are planing to do on-grid solar setup for your house, and looking to sell back to the grid, then get a reputable Vendor to do it. - If you know electric, you want something small and off-grid and you have a few electricians to help you, then yeah you can do it. unless you are expert like the other guys posting in this forum, just hire. my house setup was 6 guys working on it, took almost whole day. they started with 1. Roof rails, drill holes in the roof, attach rails 2. Attach panels 3. Wiring, and conduits 4. Dedicated Grounding rod (I now have 3 ground rods in my house, the more the better: built-in the House, EV chargers, Solar) 5. panels, inverter, meter. and of course, they left many holes not fully closed in roof, normal in Thailand that 99% of engineers cannot finish the job, always leave something undone or half done -

That's another reason I went for Solar on my Roof side that bothers me the most with the heat. It's so much cooler now that side of the house. -

I got a 5kW setup and paid roughly 210,000 baht. Without power optimizer, it would be 25K baht cheaper. - Huawei 5kW inverter (it's the best you can get in Thailand, and the Fusion solar app is pretty good) - 9 x 555watt Monocrystalline panels highest grade - 9 x power optimizer (this is optional) Batteries are super expensive here, unless you got with an inverter that supports any battery, such as Lead acid or LifePo4 batteries. The downside of the Huawei inverter is that it only works with the Huawei LUNA batteries. It's 145,000 baht for the 7kWh LUNA battery. My electricity bill went down from 15,000 baht to less than 5,000 baht now. (I have EV cars) I sell back the excess to MEA at 2.20 Baht per kWh. -
Meet the Thailand dolls! Which one are you ?

The two blue pill got me laughing "hard" 😄 -
Gold is still so useful, the second best thing you can do with your money for long term. But gold involves money, and money involves being tracked almost all times. you dont go sell some gold bars to buy a car with the cash. It's sure to be reported to the authorities. but in some countries you can already do that in Bitcoin. To buy a car with Bitcoin, the only down side is that in the Dealership records, they keep records connecting your identity to the Bitcoin address. Bitcoin is the only asset Government cannot manipulate, print notes or track people. the reason it's hard to get general public usage and acceptance. the controlling and corrupt government no way want it. Trump and Elon has a card hiding to be played later for Bitcoin, only time will tell. just wait and see.

Thailand's Solar Power Leap: Cutting Red Tape for Factory Roofs
brfsa2 replied to webfact's topic in Thailand News
It's quite a pain to get it approved. It took almost a year for MEA to get things right with me, after 10 months of waiting, they installed the wrong meter, they fined me 2,000 baht for sending electricity to the grid with wrong meter, then they realized it was wrong meter. They changed meter to the final correct one and I still lost 2000 baht 😄 TiT. 1 year later I can now sell my excess for 2.2 THB still a good deal since I break even in 4 years only. Anyways, I can only give an estimated guess: because they want to ensure safety of the solar installation since most setups will be on-grid, and the workers need a tip to do their job. Off-grid setups also need inspection, although anything over 15kW is almost always going to be on-grid. in the small town here in south some new hospital have setup a massive 300kW setup on the parking lot roof, SMART!
