And I see the SCP is once again being produced and offered for sale!

Ask them to do it?  Sometimes it is just a matter of asking. Schneider did this because I told a bunch of people to complain.
There are folks who only want to look out the window and see a picture & read Soc. It works for them. They are the boss!

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.

Why not revert to the tried, trued and tested Trimetric 2030 from Bogart engineering? I miss the old 2020 units that we installed on every off grid system back in the day.

Are there any off the shelf solutions to view battery SOC via a wired meter mounted remotely on a property? 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.  

 

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. Ideally the SOC will come from the inverter or the battery itself, not an external source (to avoid discrepancies).
