Shorter is better for sure, and using what you have is wise. If you can double the supplied wire, with that shorter length, it would better
I always try to help on load calculations, because I want everyone to have the best possible system. I am glad you are up on load and voltage drop, this is usually where most systems fail.
Keep charging! :)
Yeah I think that load calculations are important as well. Having the advice of electricians is always good!
One thing on doubling the wires and why I avoid it is because it is also doubling the resistance/ohms. If I am wrong about that let me know.
Capacitors in parallel double, resistor values in parallel are halved. Since we are fighting (small) wire resistance we can lower it by parallel wires.
:)Try it, you will like it; and it's free!
Nice One! Good to know! So basically the double wire conducts the same as one larger gauge wire would?
Basically at DC it will act that way! High frequency signals would see some differences.
Ahh that makes sense. Thanks again for your valuable insights. :)
Happy to help! Any time.

@smithlabs I came into the solar stuff knowing a good bit about DC power, electronics, wiring, inverters, AC electrical 'best practices' and low voltage systems in general but even with all of that I wish I had at the time had someone like you that I could ask questions of and get good advice from. I am not sure @ganjafarmer knows how fortunate they are to be getting advice from both a hack like me and a pro like you.
