Yes the Dual Pro will not work well in driving the motor from the generator. But, it will help keep your batteries in the bank in balance. I use my Zivan NG-1 battery charger when I want to power the motor with the generator. It provides 16 amps into the system. Works well for my needs. I think Eric has an Elcon unit that provides a little more current. Keep the Dual Pro for charging at the dock. Just add another power supply/charger and you'll be good to go with the generator.

Maybe my set up is not sufficient. I have a dual pro sportsman edition charger that I am using for my 4 battery bank system. My initial rational was to run the charger which would provide 10amps to each battery at max charge. But in my trials I could not see that I was holding a steady state charge. I have a PakTrakr that I use to monitor the system. When I use the initial set up of 100 amp max vs 200 amp max, I get two different readings (my system is 150 amp max). Anyway, when I played with the generator to run the motor, it did not appear to work well and I thought I was putting excessive stress on the battery bank (drawing and charging at the same time). I did not want to shorten or damage my current system so I have not messed with it since. I had called up dual pro to ask them about using the charger in this application and was told that it would work for awhile then the system would shut down because the computer chip would think something is wrong. To reset the dual pro you would just disconnect the power for a few seconds and it would go back to the initial charge setting. What kind of charger or set up would allow me to run the motor off my honda? Is there an AC/DC converter that is marine grade that someone has used?
