The inverter may well have suffered infant mortality when a semiconductor in the output section shorted internally and then caused the breaker to trip. If electronics fail on their own it will usully be within the first few minutes or hours of operation.
The indication of low input voltage could be consistant with the operation of a protective circuit that activates in the event of a potentially dangerous overcurrent condition in the output section (technically it's called a "Crowbar Circuit"). If there is such a potentially dangerous condition it kills the input (12V) supply.
The problem could also be with electronics downstream of the inverter. Think television, satellite antenna, or any other 110V device that is connected to operate on battery when dry camping.
Therefore, after disconnecting the 110V output from the inverter confirm that 12V is present at the inverter input. Then check for a circuit breaker on the outside of the inverter case that you can reset then check for 110 at the inverter output. Failing that, plan on replacing the inverter.
It should be a warranty issue no question. Should you decide to open the case in search of a fuse you will most likely void the warranty. If it's not under warranty then go for it - there's nothing to lose.
