Hi All,
We are half way through our new build house and are at the stage where so wiring desicions need to be made. We are off grid so have a bit of a unique situation, we have a large 48v battery bank, generator and solar. I want to use led lighting to keep power consumption to a minimum, I would aslo like to use remote switches, I was considering using (say it quietly) a transformerless supply for each light and triac dimming (with a pic). I've a feeling I might run into regulation problems (uk). Seems to make more sense to tap into the battery and run some 12v dc lines into the house for the lights and avoid losses through our inverter stepping up to 240v then transformers stepping back down for the led's. 12v is much easier to switch and I could pwm a mosfet to dim the lights.
Am I barking up the wrong tree? Has anyone here got experiance doing this? Will my losses on the low voltage dc cable be enough to out weigh the gain of not using the inverter and led transformers?
I can get away with short dc runs if I do the remote switchs, compared to quite a lot of 240 ac wiring.
Cheers Geoff
