I got this generator for backup home use. When connecting to the house transfer switch, the gfci would trip immediately. I was able to remove the jumper that bonded neutral to frame; however, this did not solve the problem. I ordered a new 2 pole double 40amp GE breaker (non gfci) that would fit the connections (was $25 shipped online or $80 locally). After removing the gfci, this unit powered my house without issue. Unit is well built and hopefully will run flawlessly when needed. This unit is designed more for jobsite use than home backup as the gfci can be an issue unless certain steps are taken. Look for a floating neutral without gfci to make the simplest connection to the house.
