No indication as to the size of the charger. I can just barely run 2 40 amp chargers at full load. The honda is NOT 2000 watts, it is about 1400 if you get a good one.
Yup, that information could be useful...
Assuming a single 50 amp charger, the Honda 2000 should certainly be up to the task. There's a thread now on this subject over on Cruising Anarchy, and Evans Starzinger finds his EU1000 to be adequate for use with a Sterling charger, but I don't know how he does it...
I have a Honda 1000 aboard for emergency use, but I'm really starting to wonder why I bother. I have NEVER had to use it aboard the boat, in fact the only use it has ever seen was at my home in the aftermath of Hurricane Sandy, when my neighborhood was without power for 20 days. If I am gonna bother with carrying one of these things, I really should have gone with the 2000. But that additional size on a boat as small as mine, it makes all the difference, as I just happen to have a perfect spot the 1000 fits very neatly into...
In testing, I've tried to get the Honda to run my older Heart Interface Freedom 1000 inverter/charger, and it really struggles. The initial surge will shut down the generator immediately. Even after dialing down the 'Power Share' setting to a very modest percentage, it barely handles it (I'm guessing my older style Heart Interface is a pretty inefficient unit, by today's standards) The only way I could get it to work, was to run it for a bit using the 12V cords to the battery, in an attempt to get them 'up to speed', so to speak... But, having to use that thing as a routine means of charging, I think I'd probably quit sailing, instead...
but, as long as I have the damn thing, if anyone has any magic bullet solutions, I'm all ears...

If I didn't need it this summer, however, I seriously doubt I ever will, and I think the smartest thing for me to do is to put the thing on eBay...
