<p>That's a long enough run that you really need to weigh the cost
of a separate system. I'm not seeing the advantages of keeping a
single system for the whole island. <br>

good one for you.. We were tasked to refurbish a
Stand Alone (aka Off Grid) power system on a 100
acre private resort island off the New England
coast a few years back.. The system has a
12kW(AC)/ 48VDC power center (@120/240VAC) with a
10kW Bergey wind turbine, 3kW of Solar and a 12kW
Diesel Generator.. It currently powers two main
lodges and 10 private cabins.. The system was
never installed properly and had significant
damage when we got there (no system ground,
evidence of several lightening strikes,
open/corroded connections, and poor workmanship in
general)</span></span></span></div>

want to build a third lodge at the other end of
the island.. Some 3600ft away, and want to feed
full power from the existing system to the new
lodge.. Thing is, the new owner is pretty brainy
(keeps me on my toes).. My first thought was to
bump the 120/240VAC up to 480VAC and send it on
like 4/0AL and back down to 120/240VAC at the new
lodge (we've done it before).. The new owner wants
to launder the AC to DC and back for
transmission.. Says DC for transmission is the new
Cats Pajamas because of the efficiency.. News to
me.. Anyone have experience with DC for
transmission? Again.. I'm shooting for 15kW
(including 25% for continuous duty), 3600ft, 600V
wire (but could go with a different wire) and a
line loss under 5%. TIA db</span></span></span></div>
