I've had this generator for a little over a year and only recently put it to any sort of extended use on a camping trip. After roughly 3 hours it started making a knocking noise and stopped putting out voltage. I suspect the inverter has gone bad and am in the process of submitting a warranty claim. Hopefully it can be repaired.
Love this unit, only thing I’ve found is the auto display will not scroll. Waiting on reply from technician. It is the 4th of July so should hear back soon.
