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...

ktmrfs, doesn't your current example apply to any 50 amp RV without an inverter?
What is the difference between with and without an inverter as far as neutral current applies?
first question, yes applies to any 50A connected to shore power
The current with inverters is a more complex calculation
My initial thoughts.
with ONE inverter, connected to one leg neutral and hot currents are equal. Two or more inverters on one legs in phase same thing.
Now with two inverters, one on each leg one needs to know the phase relationship between the two inverters to determine neutral current.
If they are in phase then the neutral current will be equal to the sum of the current in each hot leg. If they are 180 degrees out of phase like a normal 240V set of legs, the neutral current would be the absolute value of the difference between the two hot legs.
Now assuming the inverters don't either sync in phase or 180 out of phase, one gets into complex math to determine the current in the neutral and to calculate the current one would need to know the phase difference and then do the complex math to determine the current.
My opinion. If one connects inverters to both legs, unless you KNOW the inverters are synced 180 degrees out of phase make sure the TOTAL of the inverters is less than 50A/6000W or one risks neutral current >50A
