Two inverters for 50 amp service
We have a Go Power IC Series 3000 watt inverter and 50 amp service on our 5th wheel. I have 2 complaints about it that I wasn't aware of when it was installed. The monitor panel only monitors Line...

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.
Even hooked to shore power you will end up with anywhere between 0 and 50A in the neutral. It would be rare to be either 0 or 50A, but I agree, two inverters phased together will have the combined current in the neutral and 1/2 the combined current in each hot leg.
