The general rule is that all above ground earthing elements like the house wiring, electronics, ect. can be bonded together, and all the below-ground earthing elements like ground-rods, steel water pipes, and concrete rebar can be bonded together, BUT, the above ground elements and the below ground elements can be bonded together at ONE and ONLY one location. That location might be the inverter, main electrical panel, or some other designated location.
I was really regretting it when I realized I had no way of Pounding a ground rod in the ground any where ? im built on solid rock .
I use a 50 foot 12awg extension cord for my Ryobi to LV2424. Should be similar for the Growatt I would think. If you are going to run the generator at max (2200w?)10awg would probably be better. I set my LV2424 software to 10A max input (1200w) so the generator doesn't scream
So I’ll be needing 4 branch connectors correct?
About how long does it take to fully charge your battery bank?I use a 50 foot 12awg extension cord for my Ryobi to LV2424. Should be similar for the Growatt I would think.

I have only tested the generator, never used it to charge, sorry. In theory at 10a it would take 5 hours from dead to full (6kwh). I am really not pushing my system at all, but I just ordered a 9k btu mini split, so we'll see what happens when I actually use some power.
You would need four sets of 12awg wires with MC4 connectors on the end for the solar panels (4 black, 4 red), and a ground wire (I used 6awg Green). You run the other ends into the combiner box, with the four black going to the neutral bus bar, each red going to a 15a breaker, and finally the ground wire goes to the ground bus bar. Then you run a thicker set of wires to the charge controller.
Not sure I understand your question? In the combiner box or in the main breaker box? For the combiner, my MNPV6 came with a bus bar that just slides into all the breakers (it looks like a comb). For the main breaker box I am only using one leg currently, but if I expand I will just use 12awg from one side to the other.
