TechWriter, my current GoPower IC 3kw inverter/charger does incoming and outgoing L1 and L2. The problem is it only monitors and controls the current on L1.
Does the Victron Multiplus II monitor and control current on both lines?
Not if incoming AC is connected via a dogbone.

Nice post, wa8yxm. But doesn't really answer my question. BTW, neither did GoPower tech support.
Since I don't have any 240 VAC appliances, I don't see why I couldn't have 2 separate inverters and no need to sync them.
The answer to that is rather complex and involves the neutral line
With two inverters it is possible that if they are not properly phased the neutral could be carrying way more current than it is designed to haul.
120/240/120 volt Power. like a house.. Current flowing in both legs does NOT flow in the neutral So if you have say 1,000 watts of load on L-1 and 1,500 watts load on L-2 the neutral is hauling only the current from the difference 500 watts or bout 4.1 amps. But if you have two 3,000 watt inverters is 6,000 watts or 50 amps.. that's the maximum for the neutral line.. I don't like maxing out wires.

I donโt see that as a problem at all. While on shore power the 2 inverters are synchronized. If not on shore power the 2 inverter outputs are derived from the batteries and not the inverters AC inputs.

So the output of the 2 inverters would be out of phase when plugged into a 50 amp service and in phase when plugged into 30 (or less) amp service. But I don't see an issue with that. Am I missing something?

Ruined alternator due to overload? Certainly possible. Just considering the responses so far Iโd suggest professional vetting and design for this rather unique application as without that there could be unintended issues. Design problems, wiring size, loads, etc.
"Personally I donโt like what the Cptn wants to do but heโs gotta do whatโs best for him."
Why, CA? All I want to do is have load sharing and monitoring on L1 and L2 instead of just L1.
