This is 4/0 Al and quick calcs show the voltage drop at over 12%. He acknowledges that the wire is undersized to keep voltage at/about 240 volts (I have not measured directly at the street / transformer yet).<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">I know the wire has the necessary ampacity to carry his current service needs and to carry amps from the to-be-suggested solar system.<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">My concern is that the voltage drop will change the 240 volts at the street/transformer/meter to 211ish (or will I see a higher 268’sh voltage at the far house end?) at the house. The inverter will try to synch to this voltage but of course this is outside of typical inverter parameters.<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">So, instead of re-running much large wire, does anybody have experience and comments about potentially using a buck-boots transformer at the home to get us back to 240 volts?
