Search on the web for ideas about making an enclosure for the Honda.
Unfortunately the vast majority of DIY genset enclosures one finds on the web are simply boxes with a large fan at one end, an exhaust vent at the other, and clearly demonstrate that whoever built it didn't understand the concepts involved in not only quieting the racket but also maintaining running temperatures where they should be. This is especially true of noise reduction boxes built for the Honda EU and Yamaha EF series of inverter gensets which are a breed unto themselves and can't just simply be stuck in a box with a fan but instead require isolation of the exhaust gases from the intake air in order to be truly effective. The only designs I've found that address this are those from Japanese designers, with one notable exception ... this design by rv.net forum member J Auguston. I based my own noise reduction box on his design and although it's not quite as effective because I built it at minimal cost with existing materials tests show his design does properly isolate exhaust from intake air, allowing the genset to run continuously inside the box even in the hottest of conditions with no excessive heat build up. The devil is in the details. ;)
