On the iOS app, click on your profile and then normal setting. Then unselect “use new settings page”. Then go to the settings tab on the Flexboss. Scroll down and you should see it.

Wow, I just made a huge realization. The web app and the mobile app are not the same. They feel the same, and have 80% of the same options, but the web is missing things.
Web:
App:
Web is missing everything after Discharge - Peak Shaving.
Setting it to 1 for start and 255 to end seemed to work. Its night, but the smart load breaker has power now during a grid outage.
I will confirm tomorrow that it actually accepts power.

That’s great news! I hope everything works as expected. I can definitely see the advantage of AC coupling for battery charging, though standard AC coupling from installers already facilitates this—converting solar energy to AC and then using it to charge the inverter. In my view, the real benefit of integrating AC coupling within the EG4 ecosystem is ensuring that the AC solar system remains operational even during a grid outage.

Success!
Turned off grid, and eventually AC coupled grid-tied inverters starting giving power. Took maybe 10 minutes to reflect it.
I just don't know if this was because of firmware, setting change, or both.

Can anyone recommend a good funnel? I need to put my champagne back in the bottle. I let it run for an hour, and as it got closer to 100% battery, everything went dark. Gridboss/Flexboss/loads. All dead as can be.
Had to flip the grid back on to get anything to light up.
I will be calling support about it, nothing in event log.

Any luck with support and finding a resolution? I was super excited reading your previous post, but quickly fell back to earth with your last one. Lol
I’m currently waiting to get the GridBoss installed (and connect my enphase ac coupled system) by the electrician. One that is done, will hook up the Flexboss and batteries.

Maybe set the AC coupled end SOC% to like 95%?

Support couldn't find a culprit, I spent most of the time asking them about why the settings pages don't match up between phone and web. They said they copy/pasted Flexboss21 settings from 18Kpv, and some things copied over that shouldn't have(or something to that effect).
In playing around though, I might have stumble upon the root cause. My guess for now is it has nothing to do with Flex/Gridboss, but is a battery issue.
So 2 nights ago, I wanted to not have my batteries at 100% in prep to test turning off the grid. so I turned on force discharge in the web app, let them discharge about 10 percent or so. Later on my phone, I turned off force discharge, thinking the working mode would go back to backup mode, but it didn't. It went down to self consumption mode. As a matter of fact, you can't turn on backup mode in the app, best I can tell its only in the web app.
Anyway, I wake up in the morning, and batteries are at zero. Well, my fault right, I should have checked. But when I dug into the charts, it was worse. They dropped from 35% to zero in 20 minutes with no change in consumption.
Then, today, again later I tried to enter force discharge mode, and was only getting something 100w even though I had it set to 5KW. I let it sit there for a while and it never budged.
I waited about 5 hours, and now its discharging just fine at 5KW.
So my guess right now is the batteries freaked out for some reason, and since I was disconnected from the grid, everything went black. No breakers tripped, but my garage camera had a very audible click like a relay closing.
For the record, here was close to the time the blackout happened:
Sadly, AC coupling can't be listed as Solar PV, it is just invisible on this graph(even when grid is up). I don't know why it doesn't understand consumption in this mode either. You can see I had excess AC coupled PV power though, since it was charging batteries at 3393w.
Did the batteries suddenly not want any more current and shutdown or something? Again no breaker trips/alarms/events in event log/nothing.
Re-enabling grid required no on/off of any buttons or breakers.
Batteries are 2 wall mount outdoor in parallel. Chargeverter on busbar as well, but was switched off for all this.
Admittedly, batteries are new to me, this could be operator error.
This weekend I am going to try and force it to happen again with the same scenario to see if I can replicate it, so I will keep you posted.
Honestly, after today, I think it will work long term, we are just working out the hiccups.
I don't mind being the beta tester. My wife on the other hand.....

Good idea, I will test it this weekend.

The "helper" (? mark) next to AC Couple SOC End (%) says:
"In off grid mode, it exits AC couple after SOC reaches End SOC.Set to 101%, allowing the AC Couple bypass to take load after being fully charged"
I haven't disconnected the grid to test it but I set it at 101%...

Thats where the UI is just so hard to understand. I interpreted that as when you have this setting enabled:
Not when it is disabled, but the grid just happens to be down state.

It seems the reason there is not a quality operation manual for the FlexBoss21 and less so the GridBoss is that the settings pages are such utter garbage. Can you imagine trying to write this in a technical manual?
I'm glad they are continuing to work on the settings but I fear the documentation will continue to diverge from reality.

Ok, progress! Here is how you can get is working.
Step one: Take your kids to a birthday party and let your wife stay home so you earn enough credits for the later power outages.
I put a multimeter on the smartport AC couple breaker, then put a camera on it so I could use web interface and phone app, and take screenshots.
Here are the results.
The discharge settings in the mobile app are irrelevant. They don't do anything.
When disconnected from the grid, the AC couple settings don't make sense, but here is how they work.
Battery state of 84%.
start at 1, end at 90. No voltage on the breaker.
Battery state of 84%
start at 85, end at 90, and there IS voltage on that breaker, which wakes up the inverters and starts producing power.
It makes less sense as we go along though. I set the start to 87 while the battery was 86, but it blew right past it and continued
Now we at least know how the setting "works" in on grid mode, when the grid is down.
at 89% SOC, and about 50 minutes after I flipped off the grid, total blackout again. I had upped the end SOC to 92 at this point.
I added another multimeter to measure battery voltage, but forgot the camera was wireless attached to a AP not on UPS, so it died.
These were values an instant before blackout:
Battery charging hit its peak right around then, but could be a coincidence:
