I have been assuming that all of the other settings in the Magnum are using default settings, but there's a possibility that the Firefly is changing other settings that I cannot see.
Like you, I would have liked access to more of the Magnum settings via the Firefly system, but what they provided seems to work well enough.
I added a Victron BMV-712 to monitor state of charge and I'm happy with it, but it obviously cannot provide any feedback to control the charging process.
I've been toying with the idea of building an arduino-based CAN bus monitor/controller to snoop on the messages that the Firefly system is sending to the Magnum and see if I can send my own messages to set the Magnum up exactly as I want.

Excellent! Thanks for the info! I actually talked to Firefly about bringing the SoC into their display via a 3rd party monitor...possible, but costly to customize...I like your idea of using a separate home-brew monitor/controller...I have tinkered with arduino-based devices in my home automation so I like that idea too.
Sorry, one final question. Does this mean, on your Firefly screen, you have a custom screen that lets you set the charge voltages (i.e.: bulk, absorption, float, etc.)? Or does the Custom profile simply let you set it on the Magnum I/C via a separate remote (i.e.: ME-ARC) and preserve/save it that way?
