Inverter: long cable = increased consumption?

[st599]

Not sure you read my post correctly, Gypsy. I also use the inverter for powering food processors and other heavy loads.

Cozzykim: the router is actually a 24v system. My boat is 12v.

I do have a smaller inverter but I don't want to permanently install this one as it 'floats' around the boat as and when I need it. I don't have the money to purchase any more (and trying to source one on the Suez Canal could be problematic!).

Anyway, all of this has nothing to do with my original post! I have now installed 50mm2 cable and everything is good. Thanks for your comments and suggestions.

Would it not be more efficient to go 12v dc -> 24v dc rather than 12v dc -> 230v ac -> 24v dc?
