It's a Power Electronics Hands-On that shows LabVIEW & LabVIEW FPGA controlling a switch-mode power supply. I'm not sure whether your problem is that you have a simulation model of your inverter that you just want to control or whether the issue is that you want to make a model of your inverter, but either way this should show you how you can use LabVIEW and Multisim Co-simulation Tools to create a model of the inverter (this bit is done in Multisim) and then control it (this bit is done in LabVIEW FPGA).
Obviously you will need to create a model of your actual inverter but I hope that it shows you roughly how this can work when you have made the model.
As for making the model you will, as others have said, have to contact the manufacturers for help on that.
