An outdoor generator enclosure can help to reduce sound while also protecting your machine from the elements. Depending on how soundproof you want it to be is determined by how much you insulate the interior of the enclosure. Most of the pre-made enclosures I’ve seen are in the $700.00 to $900.00 price range, with portable generator tent covers running around $200.00.
Obviously, a tent style cover won’t offer any noise reduction but it will keep your generator safe from rain, snow and the elements. Building your own custom enclosure allows you to insulate if you’d like, with material costs averaging about $350.00. The following video shows a really nice custom built portable generator enclosure fully insulated with exterior control switches and a nice exhaust fan.
