i have replaced a 1.5hp with a 3hp dual phase motor with 2.2kw 230v invertor. however the new motor does not have any real difference in power capabilities. under a reasonable load the motor slows considerably until load removed. the load is not excessive. i have the same setup elsewhere and the improvement was considerable. what are the possible causes ofd this problem. a wiring fault ?. a set up problem with the invertor ? the setup is factory settings - 230v,
