Didn't mean any offense with my last comment just wanted to point out that an ev inverter is a slightly different beast to an off the shelf vfd
what i'd like to see with this project is that it stays within the limits of what a person with a soldering iron and a few hand tools can build given a pre made pcb. I'd also like to see some smart design in there to prevent or at least minimise the probability of major failures. thats what i like about the dc controller. Its small , smart and easy to build. No crazy magnetics or stupid qfp smd parts etc. I built an atmega programmer in 30 minutes from some junk box parts.
