You missed the point. The inverter output is less than the motor rating.Your name plates on the Jet are OK.
4.6 x 230 = 1058 watts, close to 1.1 kW and that relates to 1.417 hp which is close to 1.5 hp
The 1.6 kVA is also close enough, based on 240V and a high power factor.
They did a good job.:thumbsup:
