So you are running AC to the charger
or DC to the batteries?
As far as I can recall
, maximum output from the EU2000 model on the AC is a mere 13 amps continuous (see Specifications - Honda EU2000i Generator and Honda EU1000i Generator
), and on the DC side, it's just 8A (96W).
That's not a lot. Practically, I have run a Makita 7 1/2" circular saw (10A draw) from the Honda 2000, but it "sounds" close to the edge. I would not use it to power anything bigger than a 10 A Guest ferroresonant old-school charger
, which I've done when my older boat's on the hard
. With that, I can run a single
100W worklight, but that's it.
I can run that for six hours, straight, however, so the Honda is great for "low-middle draw, continuous". In many situations, it's a lot easier to haul the 2000 around than to run 200 feet of 12 gauge power cord across a wet yard.
My suggestions are therefore to a) use a smaller charger, b) somehow restrict what the existing charger can draw, c) use a short, heavy power cable to reduce loss, and d) consider longer term buying
a second Honda 2000 plus the kit to use them ganged together to provide a "real" 30 amp (or close to it) charging
Two Honda 2000s are considerably cheaper than a Westerbeke
4.2 genset, and arguably are a great deal more flexible.
