  1. No, he/she is saying the exact opposite, that although it doesn't make sense statistically he/she is still more nervous flying domestically than driving here.
  2. This one? It shows as not yet operational (the spanner symbol) on PlugShare. which I believe is pretty trustworthy.
  3. The 14.8 km/kWh seems to be mislabelled (and unrealistic). From the numbers it seems to me to be more like 148 Wh/km, so 6.76 km/kWh and a total range of about 338 km.
  4. "If I Remember/Recall Correctly".
  5. You can report two weeks early, so if for example your report date is Tuesday 20th of December, the earliest you can report is Tuesday 6th of December.
  6. Since your latest extension was based on income, you only need to have the 800k in the bank for two months if you switch to the "money in bank" option.
  7. Chang produces switched sockets that accommodate two three pin plugs (Lazada link????
  8. Looks like the Joven 500: And yes, no mention of earth leakage protection in the specifications on their website
  9. Huntsman spiders are venomous but the venom is generally harmless to humans. In fact all spiders except for a few small groups are venomous.
  10. Musk already fired half of the 7500 employees at the company, so with hundreds leaving he is probably left with less than 3000 employees. And ,as has already been mentioned, the hundreds that are leaving are the ones that have a choice i.e. the highly qualified people who can easily go out and get a good job at another company. With the messages Musk has sent out, nobody would want to work for him unless they have no other choice.
  11. So somewhere between eight and ten million Baht, that doesn't sound budget to me???? Yes, I realize it was just a typo and you added one too many x's.
  12. It's down in the corner of our land and in the wettest part, the location is not suitable as car port or sitting area.
  13. Yes, I know about top-balancing the cells, I will start doing that as soon as the adjustable power supply I have ordered arrive. I have bought this BMS:
  14. So a month and a half on, and things are starting to get real. We just picked up 14 of these JinYuan 340W panels from Global: Our local Global here in Lamphun didn't have any in stock, and neither did any other branches here in the North, so Global had to transfer panels from their Buriram branch. Then there is the question about what to do about batteries. You basically have three choices: The cheapest option is DIY with cells and BMS bought from China. Buy one of the battery packs assembled by "some guy" here in Thailand. Not much more expensive that doing it yourself, but the option comes with question marks about what quality of cells they are using. They may claim to use new, top quality cells but there is not way to really know. Also, what is the build quality of these battery packs? Finally, most of the packs come with NMC cells, which I personally don't think are very well suited for solar battery storage. Compared to LFP cells, NMC cells have their strong points (high energy density, fast charge/discharge rates neither if which are really needed for solar). But they are not as safe as LFP and have a much shorter life span. Buy a factory built battery pack. A good, safe option that more or less guarantee you a quality, well built and nice looking product, but also costs close to twice what it would cost to DIY. In my opening post I said that I would not be building the battery myself, but after doing the research I have changed my mind. Building your own battery pack really isn't that complicated, and you will know exactly what components goes into the battery. So two weeks ago I ordered 16 pcs. EVE LF280K cells on AliBaba, which will give me a little over 14kWh of storage (10-12 kWh if I leave a 10% bottom and top buffer). The cells were shipped Monday this week, and Friday morning we received a call from Nim See Seng that the cells had arrived in Lamphun, and as we were in the city anyway we picked up the packages at the depot. Just four days for shipping from China, that's pretty rapid. Both the 14 PV panels and the 14kWh of battery storage is a little more than originally planned, but once I start looking at buying something I always end up wanting a little bit extra. When it comes to need vs. want, want often comes out on top (at least for me). Next step is to have the ground mount for the panels built, which will hopefully happen over the next couple of weeks. Similarly to often ending up deciding to upgrade a bit from the original plan when buying stuff, the ground mount will no doubt end up being somewhat overengineered. But better that than have the whole thing fly away during the next thunder storm. .
  15. This seems more like a "Plants, Pets and Vets in Thailand" than a "DIY" topic.
  16. Both Bangjak and PTT are busy installing EV chargers at their petrol stations.
  17. Bangkok Bank has a 50 Baht per month management fee for accounts with a balance of less than 2,000 Baht and no user initiated activity for more than one year. The 50 Baht will be deducted every month, and when the balance reaches zero, the account will be closed. So just keep the balance above 2,000 Baht or make sure you use your account at least once a year, and you will be fine.
  18. Not exactly a new idea, they tried that in Thailand back in 2019: https://www.reuters.com/article/us-thailand-3d-crossing-idUSKBN1Y20D0
  19. Even so, he is asking for experience on the cars reliability and after sales experience. Given that the most anyone could have had the car is a few weeks, they probably don't have much to say about those areas. I am surprised that you were quoted two day delivery, since MG's business model is built to order.
  20. I don't think you will get much information of people's experience with the MG VS here. The model was only launched in Thailand two months ago, and they probably haven't even started delivering cars to customers yet.
  21. I receive bank statements every month from Bangkok Bank with my address written in the Latin script. I needed an official document same as you for my home country, so I asked Bangkok Bank to register my address using the Latin script. No problem at all. i don't know about other banks.
  22. Apologies in advance for a long post, but I want to give as much information as possible. I have read some of the topics in the Renewable energy forum, and as some of you have already done it yourself, obviously the answer would be yes. So what I really mean is; can it be done by someone starting out from scratch with little previous knowledge of electrics/electronics? I did all the electrical wiring when we build our house (with a lot of help from this forum, special thanks going to Crossy), and have had not had a single problem over the subsequent eight years, but that is as far as my knowledge of electrics go. Our electrical consumption is fairly limited, so having a professional company install solar at our house would not make any financial sense. Even if saving on costs by installing it myself, the purely financial argument for solar is probably not very convincing in our case. However, my decision on whether to go for solar or not, will not be solely financially based. We have the occasional power cut during thunder storms maybe once or twice per month on average. It’s really not that bad, but if we decide to have solar power, I want to kill two birds with one stone by going for a hybrid, on-grid system. I would like us to be largely self-sufficient, but don’t mind having to draw on the grid from time to time when there is no sun, or our consumption is at its maximum. If it turns out that we draw more energy from the grid than expected, I wouldn’t mind the option to export (unofficially) to the grid to minimize our costs. We still have the old type spinning meters. First a little information about our circumstances. As mentioned our power consumption is relatively modest and doesn’t fluctuate that much between the different months. Our “base consumption” is around 300-500 W, and we only go above 1,000 W if the water pump or one of the kitchen appliances (rice cooker, electric kettle) is on. The only time we exceed 2,000 W if the shower heater (and pump) is on, and I have never seen us go above 4 kW. Over the last few years the consumption numbers have been as follows: 2018: Total cost for the year THB 16,827 for 4,189 kWh. Averages 349 kWh per month or 11.5 kWh per day. Monthly high 394 kWh, low 312 kWh. 2019: Total cost for the year THB 18,427 for 4,504 kWh. Averages 375 kWh per month or 12.3 kWh per day. Monthly high 470 kWh, low 300 kWh. 2020: Total cost for the year THB 16,649 for 4,209 kWh. Averages 351 kWh per month or 11.5 kWh per day. Monthly high 375 kWh, low 321 kWh. 2021: Total cost for the year THB 15,694 for 4,048 kWh. Averages 337 kWh per month or 11.1 kWh per day. Monthly high 372 kWh, low 299 kWh. 2022 (seven months): Total cost for the year THB 10,529 for 2,440 kWh. Averages 349 kWh per month or 11.5 kWh per day. Monthly high 381 kWh, low 295 kWh. The cost for 2020/21 is slightly effected by the Covid discounts, but not the consumption figures. We have ordered a new EV, which will probably arrive sometime at the end of this year or the beginning of next. This will obviously add to our consumption, but as we really don’t drive that much a shot in the dark is that we will consume an additional 1,000 kWh per year for the EV. I plan to almost exclusively charge the EV using a “granny charger” during mid-day on sunny days so as to avoid drawing power from the grid. As our normal drives are only around 50-60 km, a few hours charging at 2.3 kW will be enough to top up the battery again. With the EV added, and figuring in the rising cost of electricity, my costs for electricity for 2023 will probably be somewhere in the THB 20k – 25k range. To get an idea of what kind of battery storage I will need, I logged our consumption for a month from 8.00 - 16.00 and from 16.00 – 8.00 with the following result: 39% of our consumption fell from 8.00 – 16.00 when the solar panels produce power. 61% of our consumption fell from 16.00 – 8.00 there will be little output from the panels, so will largely need to be covered by battery storage. During that month we on average consumed 10.8 kWh per day, so slightly less than a normal month (this was February). This was split with 4.2 kWh during daytime and 6.6 kWh during the “night”. 8.00 – 16.00: Average 4.2 kWh, high 9 kWh, low 2 kWh. 16.00 – 8.00: Average 6.6 kWh, high 9 kWh, low 5 kWh. Only on four days did we use more than 7 kWh between 16.00 and 8.00, so as battery storage is expensive it probably makes more financial sense to only plan for batteries to cover 7 kWh, and draw from the grid to cover any excess. From what I have learned reading other people’s topics, I will need the following equipment: 10-12 solar panels approx. 340 W. 5 kW hybrid on-grid inverter. 10 kWh of battery storage, more would be better but would come at a cost. I believe it should be possible to buy these items for a ball park figure of THB 150k, and they should make it possible for me to save at least 75% on my cost of electricity. So that would mean annual savings of THB 15k+ or about 10% of the investment. My initial impression is that a solar installation is somewhat more complicated than wiring up a new house. But then again, when I first started planning how to wire the house, it seemed fairly complicated too. In the end it wasn’t too bad. So what’s the verdict, do you think I would be able to do this myself (“with a little help from my friends”)? I don’t plan on building my own battery storage as others have done or anything like that. I will be buying ready to go equipment and just put it all together myself. And am I completely off with what I have quoted about costs, savings and necessary equipment to achieve my goal? No need for now to post links to Shopee/Lazada/AliExpress with equipment I can buy. If I satisfy myself that I will be able to do this, I will make follow-up posts to fine-tune the details. If it's a go, I plan to install the system during the dry season, the time between now and then is for planning. Thank you in advance for any input you may have to give (even negative one).
