Great vfd for a home lathe
This unit was basically pre-configured and ready to go to simply power a single-phase motor for a small lathe or similar application. If you want to do more, most of the time you can change a few pre-set variables in a few minutes. So far, very quiet, very reliable!

Works great and runs quietly
Very easy too install and setting up parameters was as simple as it gets. Works great and runs quietly. I have been running one unit for 5 months now everyday and not a single issue. I will recommend this 3.7kw single phase to three phase frequency inverter to my friends.

Good three-phase inverter
This inverter borrowed from a neighbor's house is very easy to use. It has very powerful functions. I like the advantage that it can save energy. It will not use much energy for a long time. It really saves the cost of the family. Also buy one from the inverter online store.
