Ev level one charging off 24v 4000w giandel and/or 2000w victron pheonix (open ground!?)

[NickSpadaro]

I have a 24v off grid solar set up (1500watts of panels, 2 big battery units) and recently bought a chevy bolt. When I went to charge it off either of my inverters I get the dreaded open ground error. When I test my outlets I do indeed have an open ground.

To charge from a generator I just use a "ground bonding plug" to trick my ESVE. Can I do this with my giandel or my victron? Both inverters are grounded to a grounding rod, but my ev charger is still not having it. Any easy solutions?? Do I need a new closed ground inverter? Am I screwed? I tried searching and came up with many advanced open ground issues.

Need to neutral ground bond it.

Need to neutral ground bond it.

Is it safe to use the same ground bounding plug I use in my generator in my inverter?

It should work. Safe is a relative word here. I would feel safe enough using it.

I guess it depends on the inverter. I know that this can be done on some off-grid inverters (Xijia/CNSPOWER, Giandel), without issue, but on others it may be problematic.

But if you already have the inverters grounded and are adding an N-G bond, I would also add an RCD (GFCI for you U.S. guys) while your at it.
N-G bond should be on inverter output, but before the RCD.
This will give you some added safety from shock/electrocution, given that the inverter doesn't have a problem with the N-G bond.
If there is a ground fault, the RCD should open.
