How about a solar car port on a budget?
Muhendis replied to Crossy's topic in Alternative/Renewable Energy Forum
There are things called combiner boxes which allow safe connection of multiple, parallel strings. These boxes also have lightning protection and fuses for each string. Otherwise it can be regarded as a junction box. The output goes to the solar input of the inverter. If you do this using the combiner box there is no need to worry about different outputs from each string as they are effectively isolated from each other. The output from the combiner box will be a balance of the panels best outputs and none will be dragged down by it's less capable pals. -

Digital wallet scheme may switch to cash to boost economy
Muhendis replied to webfact's topic in Thailand News
The owner of the global convenience store chain 7-Eleven has received an offer from a Canadian rival to buy the company, in what could be Japan’s biggest ever foreign takeover. https://www.theguardian.com/business/article/2024/aug/19/owner-of-7-eleven-stores-receives-buyout-offer-from-canadian-rival I thought 7-11 was an American company. We live and learn. -
Digital wallet scheme may switch to cash to boost economy
Muhendis replied to webfact's topic in Thailand News
Now I can understand why 7-11 is being taken over. I wonder if that delightfully useful shop is partially owned by a Thai family............ -
Digital wallet scheme may switch to cash to boost economy
Muhendis replied to webfact's topic in Thailand News
Suddenly, all those shops who signed up to the scheme have lost their guaranteed customers and all those eligible for the 10k handout are left wondering why they only got 9k plus an IOU for 1k. How does this scheme help the Thai economy? In my opinion it will be a disaster for Thailand. -

Thailand Has Global Ambition to Become Tech Talent Hub by 2030
Muhendis replied to snoop1130's topic in Thailand News
So it would seem that the powers that be have now given up on educating their own people and will import intelligence from elsewhere to claim the tech hub award.- 121 replies

Thailand's Schengen-Style Visa Proposal Faces Hurdles
Muhendis replied to webfact's topic in Thailand News
Quite so. The schengen system works in Europe because of free and borderless travel between countries. That is highly unlikely to ever exist in Asia. Once again. a politician has made a statement which is his fantasy idea and nothing else. -
Tourists Safe After Going Missing In Tham Nam Thalu cave

The answer to that question is "neither". The tourists trusted their guide who has an intimate understanding of caves and rainy seasons. -
Upgrade Solar Inverter+ Batteries now or wait
Muhendis replied to eddysacc's topic in Alternative/Renewable Energy Forum
Lead acid and AGM are the same thing and I agree caution about dod ranges. At 80% dod you'd be doing well to get 300 cycles out of them. Lead carbons, whilst still the same basic chemistry, are a whole world different as I expect you have already noticed. You quoted 6k cycles earlier Are you able to say at what dod this number of cycles refers? We'd be looking at just under 16½ years life expectancy. That's a huge number of cycles and well worth the investment if the price is right. Remaining capacity and hence life expectancy of batteries is based on the number of cycles at a particular dod. Once the capacity has dropped to 80%, that is when the battery is considered to be at the end of it's useful life. Have you looked at flow batteries? they can go on forever at 100% dod. They will occasionally, after many years, require membrane replacement and maybe electrolyte top up. The only downside for us mere mortals is the mortgage needed for the original purchase.
