I did write a Blog about this subject back in the early days, and I don’t think that much has changed since…

If after reading the blog, there are still some uncertainty, then I would say in few words that:

  • While 12 Volts seems to have plenty of appliances and accessories available, they are very expensive, and not always of good quality..
  • 12 Volts system required very large expensive cables and massive amperage fuses..
  • 240 Volts appliance and accessories are getting better and better at using less power, they are cheaper to buy and available everywhere..

In my opinion, the best solution at the moment would be to keep the existing vehicle voltage (either 12 or 24 Volts) for the simple, basic things like lights and driving fans and use 240 Volts for everything else…
