I'm curious if anyone has solar panels in a field approx 200+ feet away from their home. What is the preferred method for transferring power to the home inverter and batteries? Has anyone experimented with voltage drop at those distances? I was recently watching a youtube video on a water generator and he said something interesting, "if transferring power at the same voltage, DC is actually more efficient than AC." This goes against what many of us believe but it seems there is some truth to it. So it seems the higher the DC voltage I can transmit it at the more efficient it will be and I will also not have the restriction of eddy currents as I would in AC. Has anyone ran high voltage solar DC wiring at length? I am able to input 2 165V DV inputs into my unit, but I also understand at this point the DC voltage is getting to a "not safe" point. Obviously roof mount is an option but requires a lot more code and inspection processes.
