My question is what is the most efficient way to convert 48V D.C. to 220V A.C. Not the easiest or most cost efficient but the most efficient electrically?

Also if anyone has any cheats on the best way to resupply LED House light fittings that were originally 220v supply to 48V dc I would be grateful.

  • $\begingroup$ An inverter, but planning lights for a tiny house and we are looking at 12v bulbs to put into fittings... $\endgroup$

  • $\begingroup$ @Solar Mike with an Inverter (tried 2 different ones and they were about the same). I get about 50% losses so it really messes the batteries around. I also have no light bulbs all the lights are led type fittings not LED bulbs, hence my question for an easy cheat to power them directly with DC. It is ridiculous I can run around in my electric trike for a month on a charge I cannot run the house lights and the P.C for 2 days. And the battery set for the house is larger than the Trike. $\endgroup$

  • $\begingroup$ Sounds like you do pedal assist on the Trike... $\endgroup$

  • $\begingroup$ No pedals it's like a little truck, it has a drop down ramp at the back and I use it for taking the wheelie bin to the dump as well as for shopping and going fishing. Since I had that it has made me realise how bad the solar set up is. $\endgroup$

  • $\begingroup$ So what size inverter? if you are running a 8kW inverter for 60W of lights then poor efficiency is normal. $\endgroup$
