  1. 85 KVA Cummins, but as you can see bearly idling at 3 kW. Even a small solar system could easily overwhelm the grid at high noon. I could go down and take a reading late at night, when everyone are using aircons, but I might never return from such a risky endeavor if I encounter the local wildlife. The night belong to the jungle.
  2. Important information. Active balance is the way to go. While we are at the subject can you also explain what is meant by 3S, 4S, 7S, etc.? Is it number of batteries in series? Are the below models active or passive? THB 1,450.93 8%OFF | DALY Smart BMS 12V 36V 48V 30A 60A 80A 100A 120A 150A 200A LiFePo4 Li-Ion Battery 3S 4S 7S 8S 10S 12S 13S 16S 20S 24S Balance https://a.aliexpress.com/_mM8bufh
  3. It is some sort of BMS (Battery Management System), but only sparkies know what they are actually doing. Battery (used) 48V x 200 Ah or 9.6 kWh, so nearly 10 kWh.
  4. How did you do your 90 days report while the online system was, well offline, in January-March this year?
  5. That is correct, but with a hybrid the fun and action happen at night. You just toss a few extra panels on top of the roof and forget they are even there. It is all about batteries baby, both in terms of cost and capacity if you can survive from sunset to sunrise and here kWh play a critical part.
  6. As it turns out, the inverter is tied to the grid but not grid tie! The inverter is connected to the grid, so if the battery runs low at 4 am the grid will simply take over the load and you can stay in bed with the AC running. I am not sure if the inverter will charge the batteries with grid power during prolonged cloudy periods or the batteries will simply stay low and hope for sunnier days tomorrow. Anyone knows or God forbid, time to pull out the user manual? What Crossy is raising the non-grid-tie red flag about, it that you can't combine grid and solar power, meaning the entire household is limited to 5,500 W. Next step is to make a list of start up power (Amps) for aircons, water pump, vacuum cleaner, hair dryer, ceiling fan, floor fan, blender, drill, etc. Never an easy day in solar world.
  7. HomePro is not sparing any expense when it comes to shipping.
  8. Apparently grid-tie hybrid and gensets are not the best of friends. From the Internet: "However, the standard grid-tie inverter’s sensing circuit is very sensitive, especially to hz, and it will require a good quality generator for this to work. Some inverters, that are designed to work in mixed source environments, like the Outback Inverters, are capable of even working with poorly regulated generators." Even of zero export is selected, the inverter is still synchronized with the genset grid and I guess floating a few mA back and forth. That is all good, until a genset trips and the backup genset kicks in. At the moment we just experience flickering lights during this 1-2 seconds switch, but the inverter might think all hell have broken lose with such a dramatic switch. Please correct me if I am wrong, I am on very thin ice with all this solar electronics.
  9. That might actually be perfect for me, as in no way shape or form can I push any juice back into our community genset grid. Apparently, it can fry the control boards on the gensets. Do I need to replace my old aircon units and the water pump with inverter type units, to avoid the x7 startup consumption or will the 6000 W solar inverter be able to handle the older 13k BTU units?
  10. Another interesting thing about his setup is that he is running all panels in serie, but since the inverter is rated to 500V he had to remove one panel and is currently only using 9 panels.
  11. <Note this is a branch from the Solar Car Port thread which I think deserves its own dedicated thread> Just met the owner of the below system and the cost are as follow: Panels 10x470W = 40,000 baht Inverter = 16,000 baht Battery (used) 48V x 200 Ah = 30,000 baht Breaker, wire, box, etc, = 10,000 baht Labor = Self installation In total, just shy of 100,000 baht for nearly a 10 kWh hybrid system How does that compare in price to your system Crossy?
  12. Coffee hadn't kicked in yet, I totally missed the "ain't" part. Good survey.
  13. Koh Tao hospital got 30 doses for front line workers, so it sure is getting out in the corners of the country.
  14. Your survey looks like an election ballot from North Korea. You might want to include the above option.
  15. How does Makita compare to Dewalt? About same spec and price?
  16. Mao did that in a slow year. CCP are the pro, when is comes to mass culling.
  17. Ha ha! You must have taken a double dose of commie propaganda sugar today. The incompetent west then developed groundbreaking new and very effective vaccines while the best of the best will full state support of the mighty CCP produced a vaccine that is best avoided if you want to stay alive. Democracy is a horrible system, but by a million miles it is by far the best system we have.
  18. They arrested some "citizens journalists", apparently treated them a bit rough, and generally Beijing prevented information from getting out of Wuhan in order to control the narrative.
  19. Ah, got it, but it is conveniently showing sold out for me.
  20. How are they getting away with this scam? Like magic 49 baht turn into 796 baht when you select size and color. https://s.lazada.co.th/s.V48P0
  21. I don't have first hand knowledge, but something can be done. I know of what couple, he is in China and she is in Thailand. They are using Wechat for money transfer, but they are using a middleman, a Chinese national in Thailand.
  22. I am OK with slow shipping, I kind of expect 1 month delivery time, but if the right item shows up after 2 months that is also fine. As long as I don't find a brick or a <deleted> in lieu of my spanner. I am new to AliExpress and currently have 12 orders pending. Based on your experience, I will not make any additional orders, until stuff starting to show up at my doorstep. Thanks for sharing by the way.
  23. What kind of scams or wrong doing have you experienced on AliExpress? Substandard or defect equipment? Empty boxes or no parcel at all? For anything bigger than a Keychain, I usually as the vendor a trivial question about the product. I only purchase if the answer is somewhat reasonable. Also I only buy from vendors that have a high'ish rating and only items that have been sold before and have a few 5-star reviews, usually with pictures. So far, I haven't been taken to the cleaner, yet.
