I've got an electric panel with two mains, but the voltage across L1-L2 is 220 volts, and the voltage L1-N and L2-N 127 volts. 127 * sqrt(3) = 220, so this means the two lines are 120 degrees out of phase, not 180 degrees. Which means this is not split single phase service, but three phase service with only 2 of the 3 phases coming in to the main panel. WTF?
So, I've got Enphase M250 microinverters that are tripping out-of-voltage errors, either due to 220 being too low (216 supposedly the threshold) or 127 being too high (130 supposedly the threshold).
I can't use Enphase three-phase cable because I don't have 3 phases in the panel. WTF do I do?
