Nexttime I will RTFM. It turned out it was the circuit breaker on the generator itself. After reading the manual, I found the circuit breaker and reset it.
And I know what caused it. I turned on the air conditioner BEFORE turning on the generator. I should have waited until I had the 110V.
Everything works now!
