The site had or has a Bergey 7.5kw XL-R wind turbine, on a tilt tower which is almost impossible to tilt, a solar array on a stacked log tower, Kubota generator, flooded cell lead acid batteries and Outback Inverters. Your assessment of the system is 100% correct, bad workmanship, and little or no maintenance. The original design was poorly thought out as well. The poor workmanship was not limited to the energy system, the electrical infrastructure had issues as well. The original installer was in way over his head.

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)<u></u><u></u></span></div></div><div style="margin-bottom:6pt"><div style="margin:0in 0in 0.0001pt;font-size:11pt;font-family:Calibri,sans-serif;background-color:white"><span style="font-size:11.5pt;font-family:"Segoe UI",sans-serif;color:rgb(5,5,5)">The new owners 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%.
