cornishcarlos Posted January 24, 2020 Share Posted January 24, 2020 Hi, Apart from Lazada, where are people buying solar components from ? What's the better brands for panels, charge controller and inverters and deep cycle batteries ?? Lots out there of varying costs, so would like recommendations based on personal experience... Looking at setting up a small system for our little holiday hut in Chaiyaphum... 100-200w with a 50-100Ah battery, just for some lighting and charging stuff incl my power tools batteries !!! 2 Link to comment Share on other sites More sharing options...
BritManToo Posted January 24, 2020 Share Posted January 24, 2020 (edited) Amorn (in a Tesco Lotus superstore near you), Shoppee and AliExpress. Nice hut! Edited January 24, 2020 by BritManToo 1 Link to comment Share on other sites More sharing options...
Crossy Posted January 24, 2020 Share Posted January 24, 2020 Inverters from AliExpress (China), panels from Amorn, batteries - none we're grid tie. Mounting hardware from the local metal shop. 1 Link to comment Share on other sites More sharing options...

Grumpy John Posted January 24, 2020 Share Posted January 24, 2020 For solar panels try Global House if you have one nearby. In Phitsanulok store they had a stack of.......I think 280w panels for 3300 baht each. Which is a good price in LOS. If you know what else you need Aliexpress is probably your cheapest option....maybe not with inverters....but it's free to look! 1 Link to comment Share on other sites More sharing options...
Metropolitian Posted January 24, 2020 Share Posted January 24, 2020 I got my setup by: [Amorn] 330w panels from Amorn, together with 15m solar cable size 6 (They only have black) and a dozen of MC4 connectors. The inverter is from ShenZhen (China, via Amorn). [Shopee] Mounting rails and clamps from a 'local' dealer More solar cables, size 4 and 6 red and black [Local hardware] Tools, screws and snuff stuff gathered from here and there [Batteries] The setup is ongrid, one panel is reserved for offgrid. I have ordered a few LiFePo4 batteries to experiment with, the controller just came in (BMS) so that project have to start yet. Batteries will be for (emergency) lighting which are 12 volt to circumvent the conversion losses. 1 Link to comment Share on other sites More sharing options...
ireckonso Posted January 24, 2020 Share Posted January 24, 2020 Do Home has a good selection now if you have a store near you. One thing I will say you get what you pay for when it comes to solar components, many cheap panels only have a 1 or 5 year warranty, same with batteries and inverters. Your roi isnt worth much if they die prematurely and you cant get them replaced on warranty. 1 Link to comment Share on other sites More sharing options...
cornishcarlos Posted January 25, 2020 Author Share Posted January 25, 2020 Result.. I found a 45Ah battery tucked away, forgot I had it ???? That's one item ticked off the list... 1 1 Link to comment Share on other sites More sharing options...
JohnMc45 Posted February 2, 2020 Share Posted February 2, 2020 If I remember Amron had a packaged unit that might work for you. I was thinking of trying to send one home for the Hunting/Fishing shack. Battery, controller and inverter where self contained. Had 12v dc outputs for lights and fans they sold. Also had a couple USB ports and a normal plug or two. As a side note Dewalt has a 12v car charger for there 12v/20v Max system. 1 Link to comment Share on other sites More sharing options...

Save you from going from 12v DC to 240v AC back to XXv DC. Was looking at Makita here in Canada but Dewalt and Milwaukee are just more common. Makita make a tool battery powered coffee maker I found interesting. Link to comment Share on other sites More sharing options...

farmerjo Posted February 3, 2020 Share Posted February 3, 2020 Sounds against the thread but if not there all the time a single stroke diesel engine coupled to a generator would be more satisfying. Maybe or maybe not. Link to comment Share on other sites More sharing options...

While Crossy has pointed out that there is a theoretical single stroke engine, I have no idea if you are really talking about a 2 stroke single cylinder, a 4 stroke single cylinder or something completely different.

The ship and sub engines had reliability issues and many were replace with more conventional units, but materials technology has moved on since and they are possibly practical again. https://en.wikipedia.org/wiki/MV_Stirling_Castle I'm sure @farmerjo really meant single-cylinder, we all make typoing erros ???? 1 Link to comment Share on other sites More sharing options...

Years before the use of the stirlings on the vessels, Philips in Eindhoven made a 'camping generator' which gave about 200 watt of power, it was the MP-1002-CA. Looks very much like the Motobecane AV42 but without the wheels ???? same grey color I had long time ago, great bikes. Link to comment Share on other sites More sharing options...

Obviously if you're 'off grid' you'll need a battery set up but........it may be different in Thailand as I'd guess the amount of sunlight makes systems more efficient but my neighbour is the UK has given up with his battery system. He says his batteries needed replacing every five years and the cost swallowed up all the savings he made. 1 Link to comment Share on other sites More sharing options...

Yea, sorry for the confusion, I never associated MV Stirling Castle with Stirling engines but with this, the castle in Stirling, Scotland after which it was named:- Link to comment Share on other sites More sharing options...

Union-Castle Line named most of their ships with the suffix "Castle" in their names. Like Windsor Castle, Warwick Castle, Edinburgh Castle etc. I used to work for Blue Star and most of their ships had the suffix "Star" Link to comment Share on other sites More sharing options...

Wanted those for a long time, but previously batteries were the bottleneck. Now, it seems, that Lithium batteries has become both better as well as cheaper, to be considered as viable option to a house, which uses quite little energy. For example this battery pack of 120Ah (4x3.2V) = 1500KWh batteries costs 14.000 baht. I guess the point is, how long does the batteries lasts and how much energy each cycle can give without destroying the batteries. Link to comment Share on other sites More sharing options...

eisfeld Posted February 6, 2020 Share Posted February 6, 2020 For panels you can pick any brand but I'd assume 330W poly panels are right now about the sweet spot in terms of baht per watt. Retail price should be about 3.5k THB as mentioned. No need for a top brand here. Keep in mind that a 330W panel will only peak at that and on avg give you much less but for lighting and charging some batteries it'll be fine. With the batteries I would be careful. Double so in a remote wood hut (fire risk). LiFePo4 on paper have a good potential for this usecase but I wouldn't take the noname route for it. Maybe also consider putting the battery in a seperate compartment somewhere on the ground (but consider flooding). Link to comment Share on other sites More sharing options...
