DaveH I've used my 900 watt Zivan-NG1 48 volt charger to move my 30 foot 8 ton sailboat up to 2.8 knots in calm conditions with the Honda 2000. It puts out a max 16 amps. With it I am only using about half the Honda's potential output. But, it allows me to operate the generator in the "eco" mode making it a little quieter and fuel efficent. The limiting factor right now on my boat is the charger output amps.
You can't get more amps then the charger will provide. A charger should not burn up on you if it is well designed but, it won't give you more amps than it is designed for either. Capt. Mike

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? DaveH No virus found in this incoming message.
