What you and pretty well everyone else seem to miss is that these inverter style gensets are housed in a plastic case that is purposely designed to keep intake air, heated cooling air, and hot exhaust gases completely separate, meaning that simply sticking one of these gensets into a box and blowing lots of air across it is the wrong approach. What you
do want to do is butt the genset exhaust bezel against some sort of contoured seal that closes tightly and prevents hot exhaust gas and hot cooling air from mixing with with cool intake air. My own Honda EU2000i Quiet Box is designed around this principle, as is forum member
jauguston's EU1000i quiet box, a design on which mine is based ... his original forum discussion on the topic is

here. An alternate solution to devising your own method of sealing the exhaust bezel are these commercial exhaust bezels from
Generator Line.
