Dana, I'm glad to hear that you're happy with that calculator. I've considered buying it in the past but I just couldn't get past the fact that the website claims: Enter BTU to find Kilowatts per Hour ... -Nik Dana wrote: Voltage drop and Vd% We have been using a Calculated Industrie

Friends: We are missing some information. We know the mid-string distance, but what is the distance from the positive and negative ends of the strings to the inverter? This is all part of the entire string circuit and must be analyzed. We have spent a lot of time researching voltage drop.

I have scratched my head on this one before, because it seems that two terminals bonded together by a wire are essentially the same terminal. The theoretical voltage difference on a terminal is zero. How do we figure a voltage drop on a wire that has near zero volt potential between the ends
