Yeh, I mentioned before I got a bonded neutral on the generator, I gotta convert to float. Your panel is already bonded (unless you're looking to backfeed a subpanel, those usually aren't), so a bonded neutral on the generator backfeeding it ain't gonna work out.
Diesel, if you're gonna use that generator for other stuff, just make sure to build or buy a bonded neutral plug. Basically it's just a plug (w/o a cord) with the neutral terminal connected to the ground terminal in it...so you just plug that into whatever outlet in the generator and now it's bonded neutral again and safe to use. When you're gonna use it to backfeed your panel, you just unplug that plug first.
