Actually, looking at Future electronics, they have a 1100V, 1500uF model:

Now here are some things that are confusing me: We are running wye connected three-phase, (at least my motors are) and the phase-to-phase voltage is what's important; So, what are the battery (and that capacitor) subjected to??
I mean, if one does the calcs for 120V three phase, the phase to phase voltage is about 208V.
It seems doubling the IGBT rating for potential spikes is a great idea, but how does this work out for the DC link capacitors??
Thanks for any help and education!

At the moment, I only have 600v 600amp IGBTs. If people were wanting to drive that 650v motor, you would also need a different ring cap, and 1200v IGBTs. They have an 800v ring cap now.
