I wonder what the cost is to the NHS to take care of all the lung diseased smokers. Probably a lot more than £45M. That is possibly what the UK has in mind. I'm having trouble seeing a parallel scenario in Thailand.

This is a something and nothing bit of news. What's the spec. of the panels? What is the efficiency? What is the technology etc.? Nice to know they are likely to be lighter and therefore more manageable but will they now get even bigger and less manageable I wonder? As for the article saying: "Solar panels are notoriously difficult to recycle, meaning they often end up in landfill." That is not true. Check this out https://www.cnxrido.com/ I do like the idea of them running cooler.

I think I'm missing something here. Did we celebrate Songkran last year?

Went to DoHome today and was told that well worn phrase..........No Have The girl did at least say "maybe next week" ☹️

Err. I thought I mentioned lead carbon which is genus lead acid. Depends if you are talking "power wall" or box of assorted bits n' pieces but generally 33% to 50% of a DIY jobby.

That doesn't make sense. I have done this a few times now. Always for my own personal use and never any problem. It would help if you could send the link for the import license regulation.

No. I am my own import-export agency which is a pain but doable. I had to organise my own transport from Bangkok port. I will need to pay VAT for everything (about 8K) in order to release the duty free goods.

I'm getting 12 of these direct from the factory. They should be here in a couple of weeks. https://www.cspbattery.com/hlc-series-fast-charge-long-life-lead-carbon-batteries-product/

All batteries work at their best at 25ºC Lead acid loose 50% capacity for every 10º above that. Lithium loose also but not so dramatically. Maintaining a controlled environment is economically a good idea relative to the cost of the battery and their early demise. Now, If there is no temperature control the batteries are exposed to whatever the ambient is which is never going to be as bad as having a permanent 24hr increase of 10ºC but I figure for the sake of maximising my 125k 750Ah battery investment It's worth an inverter air con for 18k baht + a few AAC blocks if available.

I'm going for lead carbon gel batteries. https://www.hiteksolar.co.nz/blogs/news/106430214-why-should-i-consider-using-lead-carbon-batteries https://link.springer.com/article/10.1007/s41918-022-00134-w There are loads of scholarly articles about them, but briefly they are about the same as LiFePO4's life expectancy but a lot less expensive and don't require a BMS to look after them. They will charge very quickly but they are very heavy which isn't an issue for stationary batteries.

For me, it's more a question of what it pays for. Wasn't there talk some while ago about paying for hospital bills?

Thanks, good idea, but all the building work around here is conventional concrete blocks with middle bits missing. If I get 200 from DoHome your welcome to make an offer for 100 of them.

I wish I could enjoy some of those positives. I've been chasing around all over the place trying to get 100 off 75 x 200 x 600. I can't find any in stock except DoHome who supply 200 minimum quantity.

I know where you can get some cheap hearing aids if you are interested ????

High up is relative just so long as one's head has a bit of clearance when walking underneath. I'm not so tall but I think I would be hard pressed to avoid cranial damage if it was only 100++ cm up.........

Thank you for your important reply and I take your point re. concrete beam. Do you have any first hand knowledge of AC units falling off?

I want to make a small, air conditioned room using AAC blocks. Has anyone mounted a split air conditioner internal and external units on an AAC block wall?

You have highlighted the "cutting it a bit fine" scenario. The two choices we are faced with when deciding to go solar are; 1. Do we make enough power to run everything at random or 2. Do we build a system knowing that we must adhere to the limitations. Using PEA is a relatively bottomless pit of available power, but making your own power demands paying close attention to what you are expecting for your investment. I have always advised anyone contemplating solar independence to make a list of the equipment you have and the time of day when it is going to be used. I have to say. Most people don't bother and then wonder why they ain't got enough power. The spreadsheet is an absolutely worst case scenario. I did my spreadsheet before I started and came to the conclusion that a 12kW inverter would be required powered by 7kW of panels + 36kW of batteries. I ended up with an 8kW inverter, 7.2kW solar and 36kW batteries. It looks a wee bit underpowered but my wife and I are aware and watch what we run which, most of the time is not a problem.

There is, of course a very un-subtle reason for things getting hot at this time of the year. Inside your all singing all dancing inverter there is something called a charge controller. It spends it's entire life looking, electronically speaking, at the voltage and current coming from the solar panels and dithers around to give you the maximum power as you may require to charge batteries, run air conditioning and keep your beer cool in the fridge. Well there's yet to be invented a charge controller that can work at 100% efficiency so they get hot especially when they are made to do a fair chunk of work. They have to pour loads of charging amps into the batteries and also loads of amps into the inverter which is keeping your house (and your beer) cool.

This is probably his second reborn life already.

We used to do burn-in testing for some products which involved cooking the products which were 19 ch. data reel to reel recorders. We cooked them in a room at 40ºC for 24 hrs then readjusted everything which had permanently drifted. Inverters and charge controllers are a different kettle of fish so they shouldn't succumb so readily to high temperatures. Solar panels however, are massive thermometers and it is therefore in their nature to "throttle back" as temperatures go north. Likewise batteries loose due to permanent degradation when cooked. Less of a problem with LiFePO4's than with Pb but still a problem.

Main concern is, of course, to make enough power to keep the beer cool. ????

You asked a "simple question" and you had an answer. What more do you want. Fact is this has been done to death several times.

The method show in the Qcon drawing is indeed different to the way the worker is doing it. However, I've had a look at the Qcon manual and the method the guy it using is mentioned with pictures. I am particularly interested in this as I will soon be building a new temperature maintained solarbattery, charger and inverter room. Looking at the detail of what is required in the manual is putting me off using AAC blocks a bit ????.
