A direct DC genset would be more efficient and you could size it to provide all the power you need – but the price goes WAY up. This setup allows me to potentially leave the genset off the boat while sailing around the harbour and doing club races and only using it when travelling afar. Plus, I can justify having it at home in case of a power outage.
Love to go the DC genset route, but the overall cost puts the idea out of range.

By the number of posts on this subject this seems to be a popular and convenient way to extend your range. I'm wondering about efficiency. What are the losses going 110V AC to some other voltage thru a charger? Wouldn't a direct DC generator be alot more efficient?

I’ve seen some post on this group that they can run their Honda 2000 generator plugged into their shore power plug and use their battery charger to “limp” home. I’m wondering about the numbers.
If I have a quad battery charger (eg Pro Charge) rated at 15 amps per battery (x4 = 48v), the full draw on the generator would only be (4 * 15A * 12V) = 720 watts. I just can’t imagine getting even 2 knots at this power level. Am I missing something or do the chargers produce more then 15A when the draw out the other end is greater then 15A? Would this potentially burn out the battery charger?
