"Last year I changed from an Ed Visa to a Non-O and had to pay 20K to do so...."

May I asked if this happened with or without an agent?

Any projects that save the world should be in interest of the Brits. Once the gulf stream is gone... a lot of problems are to come.

If you want the full 130Ah then the C/20 rate would be 6.5A. Discharge at the C/5 rate of 20A and you're down to 100Ah.

 

As to the maximum safe discharge current, I'd limit it to the 1C rate of 130A or so but your available capacity will be waaaay down.

Just great Crossy! with your help and some additional reasearch on the web I managed to read the specs. and just learnt how important the c-rate curve for the corresponding battery is and exactly this is the most important part of the specs. The rest is more or less just blabla... 

Hi

maybe someone can help me figuring the maximum save discharge current of this battery without damaging the battery. Attached the specifications. Is there a simple thumb rule for it?

Thx

We are using 200Ah LiFePO4 cells in a 16S (nominal 48V) configuration.

May I ask where you bought them? I found some on Lazada but it's hard to find a reliable seller. Can you recommend one? I'm very confused why e.g. homepro and globalhouse do not sell them together with all the solar-stuff.

The BMS’s were bought on AliExpress, they both broke in the first week so I don’t recommend them.  The Active Balancers were also bought on AliExpress, they’re ok I believe.

 

I now run without BMS, but my battery boxes have breakers for short circuit protection, my hybrid inverters are set for a low maximum charge rate (I charge quite slowly so I don’t need thermal management) and to only charge to 80% SoC and 10% DoD. In effect they are line interactive UPS units the way I use them.

 

I bought the Hybrid inverters direct from MUST Solar in China, they are 5.5Kw models and cost 16,333 baht delivered all duties paid. I bought the MUST Grid-Tied inverters from Thai Jeen Solar on Lazada. I had to add those because I export on average 80 KwHr’s per day (peak 120) and we use about that too as we run all the 11 air conditioning units 24/7 and keep the house at a constant temperature.

 

The MUST Hybrid Inverters are extremely poor at exporting power to the grid.

 

The batteries were imported by my friend and sourced by his Chinese ex-wife. Unfortunately, he crashed his motorbike and killed himself a week after the batteries were delivered, I believe they are Listen 272Ahr prismatic cells, I have 32 of them in two battery boxes.

 

I would caution against using more than one battery box, if a breaker trips and they get out of sync, you can’t just switch it back on as you’ll get an uncontrolled inrush of current from the other battery box.

 

I’m looking for a Hybrid Inverter that can run 3 units in parallel, can export a decent amount to the grid, and delivers its power in all conditions without using a separate emergency power circuit, and is also fanless. I’ve achieved that using 3 grid-tied and 3 hybrid inverters but I’d like to simplify it on the next project.

 

I build high end homes in Chiang Rai for resale. 

Hi

sorry for dropping in. Do you have a special room for the lithium batteries like a bunker or how do you shield the rest of the house from the batteries? There were cases were Tesla cars started to burn and they really have top engineers and almost unlimited financials.

Is this your solution for it?

"I now run without BMS, but my battery boxes have breakers for short circuit protection, my hybrid inverters are set for a low maximum charge rate (I charge quite slowly so I don’t need thermal management) and to only charge to 80% SoC and 10% DoD.

I'm absolutely a greenhorn in this topic but would like to use one day lithium batteries - this is the reason for my question.

Now I understand better, why some of you might think, I just made up this story, because you were discussing "MJCM" inquiry back and forth 3 days ago, which I didn't know.

This goes back many years but to change from Marriage to Retirement in Bangkok required a current medical certificate (dreaded disease list) and that wife appear with you - the feeling being you may be about to do a runner from your wife was the stated reason from an officer.

".... the feeling being you may be about to do a runner from your wife was the stated reason from an officer....." It's funny, I had exactly the same thoughts, when I left the Imm office, because the 2 ladies in there where looking at each other - like giving each other signs. Well, next year I will bring my wife with me. Hopefully until then, those ladies forgot what I was asking for....and I will let my wife speak - I hate doing this because the outcome is often completly something else than what I wanted. Oh my oh my....

You can always ask to see the supervising officer

Hmmmmmmmm, I would only do this in case I'm in a very very desperate situation or if I can change the immigration office ????

I agree, the first time (ever which was in Pattaya) I did the extension of stay on Marriage and the IO asked why I don't go for the retirement one, I said "Sorry I am not yet 50" he looked at my passport and smiled and said oke ????

That's funny, the same IO was telling me the same story last year as yours. Well sure but just under the condition to leave the country... hahahaha

It's not in ISAAN! I was told yesterday by someone in my Thai class, he tried the same thing years ago at another place and they told him exactly the same story. The IO just refused to do it. So he gave me the advice to do as they say and not to argue...., while another colleague in the same class told me - he had no problem to change it in the past. I hate all these free-style thing....

but I can not change them, I can only change myself ????

Just found the following link and I only hope that this information is not outdatet:

https://www.immigration.go.th/en/?p=14714

Section 22: 

Criteria for Consideration

1. Must have been granted a non-immigrant visa (NON-IM).
2. etc...

Oh my oh my.... Still have another year to go. Hopefully, until then the IO has forgoten my question and so will not loose face. I will show the person section 22 and will kindly ask him/ her if I'm qualified with my existing Visa Non-IMM O, if all other criterias are fullfiled.

Your prerogative..... just means that you often won't receive useful information.

Mea culpa maxima, but it's just a tiny immigration office in the outback with 2 people sitting there and only one is responsible for visa matters.

Thx Ubonjoe. I need to ask you for another favour. Do you have by chance an official link or a document I can show this to the person? I have to invent anyway a nice story so the person won't loose face.

Which office?

Hi, I don't want to expose anybody nor any offices.

Hi

my current situation:

- NON-IMM O

- Extension of stay based on marriage

target Situation:

- NON-IMM O

- Extension of stay based on retirement

Today I went to Immigration and asked, if I can apply for a extension of stay based on retirement and the IO told me, that I have to leave the country first and then apply for a retirement visa. Is that true?

Hi

on page 17 of the manual, it says that this inverter is made for AGM and flooded batteries. Can one still combine lithium batteries with this inverter?

Here is the link https://en.pwa.co.th/calculate/water-tariff to check your waterbill. Because you have no waterbill based on meter-reading, you need to do some estimation. Accourding to my understand, you are using more than 25'000 liters within 15 days. This is just isane.

Insist on a bill based on a meter reading. Someone is cheating or you have a private swimming-pool in your condo.

Hi

as far as I know, one can register a scooter or car with the yellow book without a residency certificate from immigration. I have a yellow book, which is only in Thai language also names which were taken from the marriage certificate translated in Thai. The blue book for the car will have names of the owner in Thai as well if registring with the yellowbook, while the passport is only in roman alphabets. Does anybody experience this situation and might this cause any problems later on?

Thanks

As far as I remember, Tesla bought a few years ago a company, which is specialized in Supercaps to implement this in his cars. Once the "proof of concept" is done by Tesla all other companies will do the same and this will be breaken-down to aircons and smaller devices.

I read somewhere, that deep cylce batteries should be drained to 50% everyday otherwise their lifespan will be shortened - is that true?  Maybe I just mixed up a few things .

LiFePO4s are that cheap? Well, I would like go for them but don't don't know if contractors can handle them...I myself have very limited Know-How about electronics and electricity is nothing I really want to play with when it comes to high voltage...

I was thinking about something cheaper solution than lithium, because I strongly believe, that technology in batteries will change dramatically based on the huge demand for them and in a few years maybe, I will reconsider to replace the Yuasas. 4 Yuasas for the aircon during the night instead feeding power back to the grid and the rest from the grid. It's an idea and maybe more of prototyping and gaining experience than saving money.

Hi

anyone have already made experience with Deep Cycle Battery YUASA EB-130AH 12V130AH e.g. regarding maintenance and duration?

Thx

Congratulation!!!
