How are you measuring the AC voltage on the inverter outputs? If the inverter is generating a modified AC waveform (most cheap inverters do) you will not be able to measure the voltage accurately without a meter that does true RMS. A standard cheaper meter will measure low voltage due to the non-sine AC waveform.
If the output is really under voltage then yes, it can cause excessive heat and in some cases damage due to increased current, particularly in motors.
