Just to be clear, you were doing only 120vac? That is, half the outlets in the building were dead?
He turned off and tagged out the circuit breaker, not the panel breaker, so ONLY the lights and outlets on that particular circuit were energized by the inverter. (All other circuits were powered by the grid.)
I agree that a simple "tag out" without some type of physical lock/interlock isn't something you want to do long term, but as he was on-site and presumably monitoring the circuit/system/panel it doesn't seem too dangerous.
(Unless he used a suicide cable that somebody could unplug from the outlet and touch the ends while it was still powered by the inverter....I was also concerned when he said he had moved the outlet circuit to the same breaker as the light circuit, which made me suspect he had a double-tap off of that breaker, which is also a No-No.)
