Check out Delta-Q  chargers.  I believe they say they are >90% efficient.  No connection to me but I have used a couple of them.  Designed by a Canadian company but, sadly, made in China.

Capt. Mike,

I am planning a similar backup with a Honda generator. I was surprised to find that the on-board chargers, in general, are so inefficient. Minn-kota's MK 460, a four bank, 15 amp charger is the best I have found, so far. They told me it draws 8 amps at 120v ac and the ac must be sinusoidal, which I think the Honda EU series is. This means 960 watts in and 750 watts out, about 78% efficiency. Other vendors were more in the range of 60%. I was hoping to use the Honda EU1000 (for size and weight) but that looks like it will be calling it too close. I would think that with today's technology, we should be able to get closer to 90%. Did you find anything better? I will be charging a series of eight 6 volt wet cells.
