Pretty slick. Instructions could be better, but good enough
I am using this drive with a single phase, 2kW motor that I installed on my table saw (to replace the single phase 1 1/2 HP motor). It is pretty cool. I don't really use the variable speed feature for this application, but I really like the soft start and dynamic breaking.

I am interested in your single phase frequency inverter
I am interested in the single phase output frequency inverter. Can I operate more than one fan motor on one frequency inverter?

Yes, you can. But run all at the same instant from the frequency inverter.
Great 3.7kW frequency inverter
Bought this 3.7kW frequency inverter for driving motor. 3.7kW frequency inverter arrived quickly and was very well packaged. Works as described, I very like it.
