I'm pretty sure it shouldn't buzz and have replaced the GFI and the same thing happens. Any suggestions outside of pulling the GFI out and installing a regular outlet. Thanks
Your inverter is probably a modified sine wave inverter, and perhaps the GFCI you bought doesn't like it. I suggest putting a GFCI breaker in the panel and putting the plain outlet back. The breaker panel GFCI breakers are much higher quality and perform better with fewer issues. I have several in my inverter panel and they work fine with my MSW inverter.
