Ah that's interesting. So you run the NG3 with the Generator because of its capacity? I'm just wondering with the NG1 or NG3 that if you have it permanently mounted on board even in a (relatively) dry place that the marine environment will get to it over time (if not all at once) and you'll have a fire on your hands if it is connected up. I can see how in your setup though that would be avoided. Do you have any pictures of how your NG3 is mounted, that you could post to forum? That would be helpful.
Cheers,
Bradley

Of course it's mounted high and in area where it won't get wet and if it does I probably have other things to worry about.:) Just yesterday I ran it full out from about 9 AM to 7 PM while operating in hybrid mode with the Honda 2000 generator while on my current cruise. Then I got to the mooring ran it another three hours to recharge the 48 volt battery bank through the bulk charge cycle. It's proven it's self to me but, yes you do need to keep it out of the weather.

I will also use it primarily when at a dock with AC power to do a complete charge. But, I'm not at a dock that often. So usually it's the Zivan and Dual Pro in combination as I have described.

I had the Zivan NG-1 but unfortunately it is just not capable of being used very well in a marine environment as far as I'm concerned. it's a great charger but I have to take it out of the boat after each charge and sail. I believe I'd prefer a single bank 48 volt charger instead of a 4 bank charger 12V charger but am open to conversion with reasonable argument. Does anyone have a good or great suggestion on this front?
