That's basically what Nature Power said in their email to us. They said that their inverters needed perfect input from the generator in order for them to produce proper Pure Sine Wave output. They added that they didn't feel that the Onans produced high enough quality for them to use.
When Camping World told me that they were going to replace our non-functioning Nature Power with Magnum Energy's MS2012, I did some research and this appears to be well tested quality Pure Sine Wave inverter.
I just went to Camping World's web site and see that they are no longer offering the Nature Power 200W inverter. They are now offering the Magnum replacement. When we ordered ours in February, the Magnum 2000W was not available.
Strangely, they still offer the rest of the Nature Power inverter line. Surely this is a "bean counter" decision. . . and a very, very bad one.
