canuckamuck Posted February 26, 2021 Share Posted February 26, 2021 We want to turn a field shed into a temporary living space for field workers. It's about 200 meters as the crow flies, but there is a hill in the middle, so say 250. Anyhow they only want electric light (too many ghosts over there) and phone charging, no kettles or power tools, so we can go fairly light and put a breaker at the supply end if they hook up something too big. Just wondering what gauge of wire would work. This is only for occasional use. Link to comment Share on other sites More sharing options...
bankruatsteve Posted February 26, 2021 Share Posted February 26, 2021 It sounds like something you don't want to put a lot of money into since it's temporary. But proper cable even for small power usage along with poles to support can get expensive and perhaps end up disappearing in the night. I don't know anything about this unit but maybe an alternative? https://www.lazada.co.th/products/52500mah-power-station-solar-generator-supply-200w-inverter-energy-storage-ups-i1801722952-s5342318979.html?spm=a2o4m.searchlist.list.3.27461a14wqGXSH&search=1&freeshipping=1 1 Link to comment Share on other sites More sharing options...
Crossy Posted February 26, 2021 Share Posted February 26, 2021 A load of say 2A (400W) max at 250m you could get away with 2.5mm2, 2 core with a ground rod at the far end shouldn't break the bank. 1 Link to comment Share on other sites More sharing options...
kamalabob2 Posted February 26, 2021 Share Posted February 26, 2021 Solar lights for inside the shed and solar lights for outside the shed are readily available at Global House or Lazada. I'll second Bankruatsteve and suggest the OP look into such solar units on Lazada. The seal on some attractive solar ceiling lights I installed in a village carport was not great, so I had to modify the seal. 2 Link to comment Share on other sites More sharing options...
canuckamuck Posted February 28, 2021 Author Share Posted February 28, 2021 Thanks guys, I think I will have a good look at some solar options, it makes sense for the long term. 1 Link to comment Share on other sites More sharing options...

Do compare the price of running a cable (and poles of course) with going solar. It may still be competetive. 1 Link to comment Share on other sites More sharing options...
tjo o tjim Posted February 28, 2021 Share Posted February 28, 2021 Solar lights and a PV panel with charge controller for a battery is the way to go. Some of the charge controlers even have built-in USB ports for charging phones. 1 Link to comment Share on other sites More sharing options...
Crossy Posted March 2, 2021 Share Posted March 2, 2021 Solar could be a good solution, if it really is just lights and phone charging for a couple of guys. Trouble is, someone will bring a TV and suddenly the solar isn't big enough (you're probably looking at a 300W panel, 30A charge controller, 300W inverter and 150Ah + battery) to run a TV. Even a 250m run of 2.5mm2 cable will easily support a telly. Happy workers are effective workers ???? Link to comment Share on other sites More sharing options...

You really think you need that much? Most TVs seem to be in the 80-120W range in reasonable sizes. Aside from the battery I think you could cut everything in half and be safe. I haven’t gotten my Kill-A-Watt out in a while though. 1 Link to comment Share on other sites More sharing options...

At 120W a 300W panel would generate enough to run the TV for about 8 hours, on average. But if you retain the same battery you're only going to save about 1k Baht using a smaller panel.

Yellowtail Posted March 4, 2021 Share Posted March 4, 2021 Given it's temporary, the cheapest option would likely be the best. Hard to believe there wont be at least a kettle going at some point, and if one of the workers has a wife or kid that stays home you can forget about charging any batteries... 1 Link to comment Share on other sites More sharing options...
