First of all the Soliton1 won't control a sepex motor.... So the fact you couldn't parallel the controllers and expect it to work doesn't matter.

the soliton1 right now doesnt have regen. Kelly makes a 400amp controller that does regen.
can a system be set up that the soliton controls the motor for acceleration and then when the bake is pressed it switchs to the kelly to send energy back into the traction pack?

This is not a recommendation for or against, but look again at the Kelly website. They recently introduced a 1000 A 144 V sepex controller. If you get one please let us know how you like it.
Disregard my question
Just found it:

Looks good. I just hope it lives up to claimed performance.
The Kelly is designed like most others for you to provide a proper heat sink that will properly move heat away. You must put a heat sink on that controller. You could put a water cooled one on or a finned one on. I have a finned heat sink and will be including a large fan to help dissipate the heat away. Worked like a charm on my other controller.There is just one thing that worries me.
I know Soliton1 is like 17lbs and with the fans it "barely" manages 400A continuous with IGBT.
Kelly claims 450A continuous without fans, with mosfets and at 11lbs.
Or maybe 450A is with water cooling though I do not see where the water inlets are. Then what would the ratings be as is (without fans and without water)? 300A?
Definetely needs testing. If it lives up to specs, it can be a great controller.
Maybe Major/Tesseract will have some comment on it?
Nothing wrong with mosfets. They actually work quite well. They have been used for a long time and have a proven track record.Oh, and it uses MOSFETs too!
Yes. Other reasons are that it can provide 1000 Amps continuously and of course that it has built in contactors and precharge circuit so you don't need to mount those externally. All those things add up so to be fair you should compare weight and price with those external components included.Each mounting application is different. Soliton1 heat sink is built in and is also set for water cooling. That is one reason it's so blasted heavy.
So, what's the complete price tag when it's all done? How much have you paid when you sum up the cost for the controller, the contactor, the heat sink, the precharge circuit etc?
Indeed. They also have their limitations which is why IGBTs make more sense in high power applications.Nothing wrong with mosfets. They actually work quite well. They have been used for a long time and have a proven track record.

Qer:I know Soliton1 is like 17lbs and with the fans it "barely" manages 400A continuous with IGBT.
Which is correct?Other reasons are that it can provide 1000 Amps continuously and of course that it has built in contactors and precharge circuit so you don't need to mount those externally.
Actually, Plamen, the Soliton1 weighs closer to 33 lbs, IIRC. And, yes, if you insist on running it continuously on fan cooling alone then the maximum current will generally get derated down to about 400A after a minute or two. That's still higher than the maximum continuous current of a Zilla Z1K with liquid cooling so I don't feel particularly bad about that spec.There is just one thing that worries me.

See that phrase from Plamenator I put in bold? Yeah, I guess you missed that in your haste to lambaste us, eh?Which is correct?
