Some things to remember about igbt modules. You need a 2 pack module minimum to build a controller. You need a switch and a diode. So with those modules being 1 pack modules, you will need 2 of them to build a controller. That means with the 4 modules you got, you will be able to build a 600A controller before derating. it would be wise to cut that 300A limit each back to probably 225A to 250A max.
