Help with Q.Home ESS (QCell) System Setting Battery for Outage

[Aceman]

So I had solar panels installed by Axia and they have never had anyone teach me about the system despite repeated requests (that's anther story). What I want is to stop the battery from disharging when a power outage is scheduled (happen in my area several times a year). So if you see the attached screen shot I believe this is where I would do it. From the manual (see attached) it appears as though I enable "Grid Tied Min SOC En" and then set it at something high like "80%"? Also attached is a screen shot of my current settings.

Is this correct?

Also I have two batteries so I assume I need to do this same setting with both batteries?
