If the inverter is MSW your ordinary voltmeter will read 97 or so it varies. You need a fancy meter (RMS something) to get the "real" voltage.
If the inverter is PSW then it should read the full 120, same as shore power.
I will second that. The fancy meter is called a "True RMS Meter" Rms means "Root, Mean, Square. and if you were to look at the curve of the power output on a scope it is the area "under" the curve (Between the line of power and the base or zero line)
All very confusing but many meters are "Peak reading" and due to the Flat Top of the Modified wave... The peak is lower for the same area.
