I see a broken neutral. Start at the service FROM the meter IN the panel and measure the volts from each side to ground or the EGC - not the neutral. If it's anything but 120 volts - high, or low for that matter, the neutral is broken somewhere before the panel, - maybe the meter perhaps? Then measure the voltage in the panel from neutral to the ground or EGC connection. Voltage from neutral to ground of anything over about 2 volts indicates a busted neutral somewhere. Hope that helps you.
