My inverter and charge controllers do not have ground-lugs. I measured ~ohms between all DC-terminals and metal enclosures of inverter and charge controllers.
I still would like to ground metal chassis (by bolting on a ground lug of my own making) of inverter and charge controllers to a DC-ground bus bar inside metal cabinet (which is also grounded to same DC bus bar).
On the AC-side (output of inverter):
Inverter neutral and AC-ground are NOT bonded.......bonding will occur at main panel in which inverter AC-output connects via transfer switch.
I plan on bonding AC ground of inverter to the DC ground bus bar.
Does this sound like a safe plan?
I'm dealing with 150VDC and do not feel comfortable not having any of the metal chassis of the electronics components not properly grounded with metal cabinet (which is also bonded with house-ground) which houses everything.
PS: Within cabinet, all DC breakers and SPDs are housed in their own DIN enclosure, which is also bonded back to DC ground bus bar.
Thoughts?
