Starting the gen, supply cuts out after about 15-20 minutes. i am using the single phase outlet on the gen as the mini apartment is single phase wired, the voltage meter will still be reading 240 after it has cut out and the green light keep flashing, i had used it on single phase for about five months without any problems
