There is a product I'm looking into buying that has a 0.25kw, 0.6A and 3000r/min motor. Which genetry solar inverter will run two of these motors at the same time? I used w=va and got 416v.
Firstly, you need to know the voltage rating of the appliance. I haven't found an appliance--or motor--that didn't list the rated voltage on it somewhere. This determines what you need to power it.
I did see on one of them its 380v the other is 220v

Are they 3 phase motors by some chance? 380V is normally either that or DC. If 3 phase then any GS inverter with a suitable VFD would work. If DC, then it would depend on the motor as Smartdrive motors are pulsed DC as would be some of the servo motors. Again, you would just need a suitable power supply to hook into the GS inverter. I can run a 330VDC .9HP 3.3 Amp motor on a VFD and a 3000 Watt Inverter.
Obviously, 220v/240v is pretty easy for a GS inverter to run, and the low amperage will not be a problem for any of 'em.
If you need to run 380v, for smaller loads like this a step-up transformer would probably be the most economical choice. But it is possible to "split-phase sync" 2 GS inverters to get 360 (or 380) and 408 (or 440) volts if necessary. I can find a photo of a test I did on this some time back if necessary. Basically running the "slave" inverter 180 degrees offset from the "master", you'll have 240 + 240v out (and of course can change the voltage to 204 + 204 out for 408 total, or put a 240 + 120 together for 360v, etc.)
If you need a large order of inverters for a specific task, we can talk customizing; making a 380v output inverter is not too difficult.

while I love the other two options and I know they will work I think simplicity of the 380v inverter saves the day.

We will need to talk customization and price. We don't have transformer winding machines here in the States (yet, though it's been talked about), so a custom machine would have to be ordered from the factory. Not impossible by any means, just this isn't an off-the-shelf solution.
I would suggest calling Sean at 833-Genetry to discuss your needs. It is completely possible to meet them, just we need to figure out what exactly you need.
