Note, this is in the USA, where the street lines are 4,800vac (I think?)...and the lines from the pole are 220VAC to the panel. For example, let's say I'm making 225vac from a DIY solar array (connected to my main panel), and the amount of energy I'm currently producing is more than what I'm consuming at my house (and there is no net metering setup...just solar panels with inverters pushing 225VAC connected to my panel). Assuming (since I'm in the USA) that the power coming from the street to my panel is 220VAC, and the power at the line is much higher (4,800 right?).......can my excess (unused) current get to my neighbor's house? I always thought it could not, because the line at the street is MUCH higher voltage. However, someone said it can, because the transformer at the pole would simply take the 225VAC and step it up so it could flow back into the grid, and be used by someone else in the neighborhood. Is that right? Will the transformer step the voltage UP?? Like I said, I thought it would not....but someone recently corrected me and said it will. Anyone know for sure?? Thanks!
