Grounding... I need help

OK. Quick overview. 400 watts of roof mounted panels. Epever MPPT controller. 230AH 12V battery bank. And a newly purchased Victron 12/1200. All of this is setup in my garage where I run a 14/2 to my home office to run laptops etc.
Before I had a Magnum Dimensions inverter with a GFCI, so I never paid attention. But yesterday, I got the Victron setup. Open Neutral… I read the manual and I see that I can switch the jumper and bond the neutral to the ground. But then I need to ground the chassis. Here is the problem. I don’t have a grounded rod in the garage. Being that it is “Off Grid”, and not tied into my house wiring, can I use a ground from a nearby outlet? I do have a copper pipe that is working as a drain, but I have no idea how deep. Or do I just leave it be?

Any help would be appreciated. Thanks everyone!

Have you considered adding a GFCI outlet box after the 12/1200 connected to the line terminals, and using the GFCI load terminals to power the 14/2 to your home office?

Appreciate the response!
That’s a good call. I was under the impression that I had to ground the GFCI for it to work properly but that doesn’t appear to be the case. Regardless, it’s a good safety measure.

I would still connect the ground wire to the chassis of the 12/1200.

The GFCI senses a difference of current on the line and neutral and trips to protect you.
