Wrenches
We have done transformers for issues just like this with good results, the cost
vs the new wire, conduit and trenching must be done to make sure which
direction. We have had to use paired mcm 300 to make residentual so run the
numbers

</div>Perhaps I missed it but you didn't say what you measured the voltage to
be at the clients service entrance panel at his house?

Yes, what current did you use to calculate that voltage drop? How big is the PV
system?

Good day,
I have a potential client that has an existing 1,000 foot run from the meter
and transformer at the street to the home. 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).
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.
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.
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? This would need to be service entrance sized.
