Thanks. That's my next step - to isolate each inverter and see if only one is the offending unit. It's an 880ah battery with a desired charge rate of 200A, so ultimately I will need at least two inverters.
I did rig up a 3000W solar array and was able to charge perfectly to my desired setpoint using XW charge controllers. It seems to be a calibration issue in one or multiple inverters, so I may need to resolve the discrepancies between actual and reported battery voltage or just adjust the setpoints to account for the discrepancy (not ideal).
