Hi, I have a very similar system setup to this one 400w solar with alternator charging except I have the 3000w inverter charger from Renogy which states in the manual to use 4/0AWG cable to the battery.
Reading online about ground wire sizes, everything seems to suggest to base it on max load potential so I assumed 4/0awg. However, my inverter manual says it can be grounded with 8awg.
Does this sound correct, it seems like I am missing something.
