Noob trying to figure out grounding, so better run this by you all before I destroy life/equipment.
I am building a portable system very similar to this: https://www.mobile-solarpower.com/mobile-48v-system.html
Here is a photo of my current setup (battery+pv+12vStepDown not wired yet)
My Growatt Inverter doesn't have a chassis ground. I read in various comments that it grounds through the AC Input.
My Battery does have a chassis ground....
Ground via AC-IN?
am I correct that I can "just" ground via the AC In? So if not on grid, I could build a "pluggable" grounding rod from these parts+wire, plug the AC-Input into it, and I'm all good?
Battery Ground?
What about the battery chassis ground? This post says that if the AIO AC-In is grounded, the battery chassis doesn't need grounding. https://diysolarforum.com/threads/how-to-ground-wills-hand-truck-system.64729/post-810224 so nothing needed here?
If I do need to explicitly ground the battery, Could I tie it to the ACIn Ground and that's all good? That's what I gather from this nice doc: https://diysolarforum.com/resources/grounding-and-bonding-the-mpp-lv6548-inverter.323/
Bus Bar?
If I really do need to tie the battery into the AC In's ground.... whats the best way to do this in my setup photo? Buy a bus bar like this photo? Should I also tie the hand-truck frame into it?
Thank you much for the read/help.
