Earth Ground and DC Negative bonding

Hi all. I am located in Australia where we use the Multiple Earth Neutral system (MEN). I am off-grid so have no connection to the main power grid.

My question relates to Earth Ground and Negative bonding. I have a Classic150 the instructions for which state NOT to bond earth and negative as the internal GFP circuitry achieves this. My question is, can I bond Earth Ground and Negative on the AC side, that is in the AC distribution Board without affecting the Classic?

Thanks for any advice.

I have all my all my negatives tied and they go  to ground rod and same one as AC ground goes to .
Not sure if this is proper or not but it the way I have it.
Those with more  technical expertise  will have to weigh in on this.

Thank you ClassicCrazy. I have received advice from Midnite that yes I can on the AC side bond Earth and Neutral and still use the Classic's GFP monitoring circuit. I guess this post can now be closed.
