My question is concerning grounding in my rv. My intent is to ground the solar panel frames, 4 charge controllers chassis and the two multis chassis to a single point on the Motorhome chassis. The new lithium batteries are placed next to the inverters and all goes through appropriate fusing and disconnects for the size system. The cables for the old inverter (3/0) are in the compartment where I have installed all the new equipment and my intent is to use those cables to run back where the old batteries were and install buss bars to handle all the connections (chassis ground , house distribution and alternator charging) that went to the old lead acid batteries. All the aforementioned equipment have new pos and neg buss bars where everything is landed and the neg would be chassis grounded about 10 feet away on those old inverter cables on the same chassis rail but due to the location it would be a feet to ground it all in that location. Is this acceptable or could I have a potential for a ground loop somewhere even though all the equipment will only have one chassis ground but some in one place and some in the other. Also is it safe to daisy chain my chassis ground for the two multis with a cable that would handle 1 not 2 going into a ground faulted condition or would it be a better practice to run each one to the grounding point separately and I suppose the same question applies to the charge controllers as my intent was to daisy chain them as well using a cable sufficient to handle one faulted at a time.
