Sorry, wrong answer, but my fault. I didn't formulate question correctly. Why do you see 60Vac from ground to neutral, or from ground to hot when measured with a digital volt meter? And why does an analog meter measure perhaps only 6V? The inverter is not bonded.
wa8yam comes close to correct answer.

A couple of test questions.
1. Why 60Vac?
2. Why does the analog voltmeter read about 6V (from gnd to neutral or gnd to hot)?

Sal, it all has to do with how inverters work, particularly the cheaper ones. A bit tough to explain, but in a nutshell, when producing the AC power is creates a positive and negative voltage (think sine wave) using different parts of the circuit. Instead of trying to invert the one side to increase voltage, it's easier to connect 1 output to the hot and the other output to the neutral. Run each at 60VAC, and you get 120VAC across the outlet. Most devices won't care either, so long as what they get is 120VAC. Clear as mud? Anyway, read Inverters By Wikipedia; that could probably explain it far better than me.
At least, that's how I see it.
Cheers!
