Let's say, for example, I have 3 SMA SB7000 (7000 Watt) inverters configured to 277V connected one per phase (phase to neutral) to a 480VAC line. I have it connected to the service with #1 Cu wire (R = 0.154 ohms/1000') and the distance is 100'. What is my voltage drop?
a) 0.67V
b) 1.16V
c) 0.38V
d) none of the above
And should it be compared to 277V or to 480V to get the %VD?
