I am building a cabin (5mx5m) and was considering powering it by 12v DC. I’ve looked around and seen loads of solar & wind kits, however these are aimed at providing power which is converted to 110v or 240v AC. I’m looking for mine to be a bit like a caravan, with battery bank charged by wind/solar supply – outputing 12v DC to 12v DC devices. So if you know of any guides which show
1. Power sources (wind, solar etc) that generate 12v power
2. Wiring or systems to smooth the combined supply
3. Charging systems to charge 12V battery bank
4. Wiring for 12v supplies to sockets
I have a fair understanding of electrics (not an electrician – but have done some 240v wiring) and keen to understand what can be done in kit form versus what I have to do myself
I’d also be keen to hear from anyone who’s done similar as I know there are challenges – heating for example!!
you wan t to look at marine chandlers/boat suppliers and boating in general. Boats run off 12 v systems and there are a half dozen wind generators……..including AeroGen and Ampair…….that put out 12 v for boat systems
I know two people who run their houses off 12 systems, and 2 who have 12v lights and fans as backups for when the grid goes down……

This new educational kit lets you explore the mechanisms involved in harnessing the alternative energy of wind power. The windmill features loop-wing design that can be rotated by the slightest breeze. You can also run while holding it to generate wind artificially. The kit comes with a rechargeable vehicle that uses power generated by the windmill, running for 1-2 minutes for each 5-10 minute of charge.
