I have a 3 HP Perske spindle and need buy an inverter for it. Is it adequate to match the 3HP spindle with a 3HP inverter, or do I need an inverter that is rated for more HP than the spindle?

When I requested a quote from a supplier of inverters, I was given a quote for a 5HP inverter, which is why I am asking the question.

Cheers,

Dan
