Also, the control board doesn't care what power electronics you use. And the same goes for the driver to some extent. With good surplus igbts, you can do 250HP for under $500 I think. And 10 HP is close to the same price. It's the same way with DC controllers. A Homemade 72v DC controller costs like $300 to build, and new it's only like $500 or $600, but similarly, you can make a $400 144v 1000amp controller, or pay around $2000-$2500.
