Before you bury the power do place warning tape in the trench.
They make tape just for this and it is readily available
You place the tape above the wires more close to the surface so if and when someone digs in the dirt they hit the warning tape.
Next make clear map with measurements from fixed things like buildings and clear description of the trench and place copies inside power boxes at each end .
Regarding VFD selection in general.
You did well but others are suggesting wrong approach for final selection by simple derating.
Yes you can start there but as you did contact manufacturer or download the manual to see if the device will work on single phase and which model is listed en motor size.
We did this with our Allen bradley as we needed 2 hp and the manual stated 3 hp needed with the model number so eBay search for that specific one and 199.00 later we are golden.
