Quick results on the electric drive system.

Used the electric drive for 10-minutes to get out of the slip and out on the fairway, then raised sails and enjoyed the 12-15 knots of wind out on San Diego Bay. As we were sailing at 6+ knots most of the time the electric drive was able to regenerate and recharge the batteries a bit. On the way in, we motor sailed for about an hour instead of tacking about half a dozen times to round Shelter Island. Net Result, we ended up arriving back at the dock with 0 (zero) voltage used! Still at 100% after a day’s use. I don’t think my solar panels will know what to do with the time.

I mounted a couple of pieces of King Starboard inside the starboard pilot berth’s storage area and used that to mount both the 12 and 48 volt distribution systems.

Above: The 48v Pos/Neg BlueSea BusBars. Below those, and in the forefront of the photo is the raised mount for the eDrive’s Class-T fuse and capacitor. I wanted them to ride above the bundle of 2 AWG battery cables, but below the BusBars. I also ran the system’s On/Off switch to the panel’s cabin-facing side (see below).

Electrical system’s vertical home. From left to right; Fusion stereo, Sevcon 48v/12v DC/DC converter, 12v fuse hub, 12v BusBars, thermal fuses, the 48v BusBars and, finally, the 48v, 18A, Delta-Q QuiQ charger.

Here is the heart of the electric drive’s 48 volt distribution system. Banks three, two and (to be installed at time of photo) one for left to right on both positive and negative sides, with the various charges and taps. The fourth spot is the eDrive’s power feed (to the 250-Amp, Class-T fuse — then the On/Off switch — then the capacitor that feeds the 3.8klw electric drive system itself. 

And, finally, the simplistic eDrive meter and On/Off switch located behind the seat cushion. There is another, programmable eDrive control mounted on the pivoting electronic’s panel.
