I design electronic equipment for a living (amongst other things) I just 
completed a salt water chlorinator that controls 60A of power.

Having said this, if you can buy, then buy. Designing is a pig when you 
can't pop out to the shop for a replacement part because you are 20m down.

You can't design, build and test a unit for the cost of a commercial 
controller.

Someone asked for a controller for 36v 100A bidirectional (obviously that 
100A figure is at stall). Check out:

Here's a dual motor controller:
