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.

I have a client with a simple voltage based meter for lead acid batteries that they are accustomed to using as a quick and approximate gauge of SOC. They want something similar for their new Sol-Ark with EG4 LL batteries. <div dir="auto"><br></div><div dir="auto">They will have smartphone app visibility, but they want something they can see inside the house without picking up a phone or going out to the inverter.
