I don't want to add a device that provides a separate (different) state of charge than what is reported by the BMS itself. That is just going to lead to confusion and complaints from the homeowner. I was hoping the Sol-Ark could feed SOC and voltage information to a simple external display. I'm leaning toward the cheap tablet idea, but that isn't ideal because the Sol-Ark app doesn't automatically refresh, so it can't be used to display the current SOC without physical interaction. I suppose I could use a web browser with an auto-refresh feature. But this isn't really what I had in mind.
