Got the charger working! Turns out the charger controller didn't fail, my 12V battery (which powers the charge controller) just got too low and the internal relays of the controller were cycling without enough voltage - making a buzzing/clicking noise like something had failed. The 12V battery just needed a charge up. Now I have the extra module showing up but not a big deal - it was only $45. I feel batter that it didn't actually fail.
Elcon reprogrammed it to 5KW from 6.6KW for me yesterday. It will be able do a charge from zero to full in about 8-10 hours and won't push my 30A circuit anywhere close to trip. Most often with this car I'll plug it in after every drive so I should only be looking at a few hours in reality to top it off. It's unlikely I'll ever run it close to zero.
What I'm still missing is the ability to see state of charge (a fuel gauge). There aren't any aftermarket solutions out there for the higher voltage setups like this yet but EV West told me they're working on a CANBUS shunt that will talk to my BMS with a firmware update and show charge level on my controller display. That should be a nice solution.
