I have a similar system, 680 watts solar, mppt 100/50, multiplus 12/3000/120-50, 4 Battle Born 100ah lithium batteries.
"Input current limit ... 50.0" as shown in your image means the inverter has been set to 50 amps input max.
To understand your system, when connected to shore power
Can you run the air conditioner(s) with the inverter turned "off"?
Can you run the air conditioners with the inverter in "charger" mode?
Can you run the air conditioner with the inverter on ("invert" mode)?
As Chad Heiser mentioned it is important to know whether you have a "sub-panel" installed. Trace the 120vac input wire from the inverter back to its source. Is it a breaker sub-panel? If so it is likely that the breaker that feeds the inverter is 30 amps. So you are limited to 30 amps input to operate the inverter in "charge only" mode. Open up the sub-panel and look at the main breaker in it to verify. Looking at the sub-panel box will also enable you to determine what loads in your RV have been wired through the inverter. Usually the air cond., microwave, entertainment center. 30 amps is sufficient to run the inverter's battery charger. So you should leave the inverter in charger only mode.
If you can provide the above information I can try to help you.
