12V to 240V inverter 500W can be had for 50 GBP. Add a transformer for 240 ...24 ? It does seem bizarre to use a 12VDC to 240VAC inverer, only to convert the 240V back to 24V - but I s'pose that's "economies of scale" for you?? :-( How does the efficiency of going from 12VDC to 240VAC back to 24V compare to going directy from 12 to 24? I was recently in a fairly remote part of Mozambique - where they have no mains electricity - and they were bemoaning the fact that it's difficult to get a laptop PSU that will simply connect to a 12VDC supply (eg, car battery or solar-charged 12V battery). Actually, I think CPC have a 12VDC lapop PSU... |
