The specifications on this inverter look OK...
Since this is the second one you've had trouble with, I suspect that either their quality control stinks OR there's something amiss in your onboard setup.
What size cable are you using to connect the inverter to the batteries? How long is the cable? Are you connecting directly to the batteries, or thru a breaker panel? This inverter can draw 20A.
Before returning the inverter, I'd be very sure that it's getting the power it needs to operate properly. Small wiring, long runs, dirty contacts, low batteries, etc., can combine to drop the actual input voltage to the 10.5 volts or below, at which point the inverter may cut out.
