Arlid:
The electrical system was designed by Mickey Smith, as you suspected. Mickey and I have a funny history together. Decades ago, when I ran a computer game company (Sierra On-Line), Mickey was our representative from Intel. We were located at Yosemite, and he once brought his family along for a tour of our studio. I never would have suspected we would wind up someday linked in a completely different way. It's a very small world. Mickey also had a 62, and is likely someday to be an owner again.
Our cruising alternators were Electrodyne on the 62, and I'm fairly certain that's what we will have on the 68. I'm not sure of the exact model. I didn't know that Dashew had them on his boat. That's quite an endorsement. Here's a question for you: I had always thought there was a direct correlation between horsepower and fuel. Aren't the hydraulic alternators consuming exactly the same amount of fuel that an equivalent generator would? Nordhavn owners usually speak of their output as "free electricity", but I'm not sure it is. In my case, I'm happy to have a little extra load on the engines. With twins, I'll be consuming only about 90hp per engine much of the time. I'm not sure constant under-loading is good for an engine.
As to the house battery bank: . we'll have 1,530 24v amp hours. That should be enough for our use. 99% of the time it will just be Roberta and I on the boat, and we're pretty conservative on using power. On Sans Souci, our 62, the primary power consumer at night, while at anchor, was the sat TV positioning unit. I always had to power it off, and the Fleet 77, before going to bed.
"...How do you split the load between the genset and the inverters when you have central air using chillers?...
It has been a few weeks since I looked at the electric panel. I need to do some investigating to answer this question. I'll look this afternoon...
...Well if you get stuck feel free to send me an email..
Thank you!!!
