Great Voltage Drop Calculator

For those of you trying to figure out wire size / voltage drop for your electrical systems both AC & DC I found this site:

Voltage Drop Calculator - for single and 3 phase ac systems and dc systems

I know nothing about them as a company just a cool calculator

This is a nice calculator. Checked the volt24 voltage drop for my solar . I used the round trip both neg and pos of 24 ft(12 ft distance) with 24 volt 15 amp to controller withe 4 gauge wire and came out with a voltage drop of 0.8 percent. So I am doing good and can upgrade to 30 amps with no problem. a drop of 1.5 percent
