Have you considered cabling loses? There is a reason power lines use very high voltages.

Have you considered cabling loses? There is a reason power lines use very high voltages.
- webignition 12y agoI've considered voltage drop over cable length only in as far as I'm aware that it occurs. I haven't tested the level of voltage drop. I currently use 12v circuits in my camper van and haven't experienced any significant drop over cables about 3m in length. LED-based lighting and a 12v fridge operate as expected and the voltage at the point the power reaches these devices is very close to the voltage over the battery supplying the current. I previously used 12v circuits in a narrowboat I used to own and didn't experience any drop over cables about 20m in length. This used halogen-based lighting and again the voltage at a lamp was very close to the voltage over the battery.
