This also looks new to me. I wonder if this is the switch needed for those with Schneider DC charge controllers and looking to sell to the grid.

I have the Schneider MPPTs, and have always been able to "sell to the grid" (I know I sound like a broken record, but in my case that just means "backfeed to the main panel" since I do zero export.
I saw this setting too, but no idea what it's use-case scenario would be.
So, After continued testing. I decided to try something.
Flashed firmware 1.18b41.
Then, I reset to factory defaults. I set the absolute bare minimums up (network (wifi in this case), disabled the onboard charger, and setup peak load shave to 0 amps, and grid support voltage at 52.0.
I left it in that configuration for a couple of hours (previously, the insight was freezing every 20 minutes or so (To be honest, I never timed it. but thats what it "feels" like)
After a few hours, it was still rock solid.
I then let it detect my wattnode, and configured "Grid Sell" with -1200 as my "Zero Export" target, and set to 10 max sell amps. (I know, the XW can do more, but right now my grid wiring and breaker are undersized until this winter when I feel like spending a couple days in the attic to run larger wire).
In peak load shave and "zero export", it was again rock solid for a couple hours. This was yesterday.
This morning, I got up, saw it was still working.. so I plugged in the EG4 Lifepower4 communications hub (if you don't have one, this acts as the BMS, and gets wired to the insight home). *note* I did not *detect* the BMS, or setup anything around the BMS... so, no SOC control, or anything. I literally just plugged it in and nothing else. 20 minutes later.. the insight home is frozen. I then power cycled the insight, and it continued to freeze up. So, I unplugged the comms hub, and power cycled the insight. It's been rock solid since.
So, on a hunch.. I changed the DIP switches on one of my batteries, and plugged in the cable from the insight direct to the battery (bypassing the comms hub). and voila. Rock solid. Gave it 2 hours. After 2 hours, I unplugged the cable from the battery and back into the comms hub. and guess what? Then endless "freeze and power cycle" thing started up again.
Unscientific, but I suspect something between firmware version 1.10 on the comms hub, and 1.18b41 on the insight home is causing the insight home to become unresponsive. And once again, when I was on 1.17, and 1.18b33 (the one that was pulled quietly) I never had an issue.
I'm curious though, if the new insight home will suffer the same behavior on 1.18b41, with the comms hub. I'll find out in a few days, for sure.
Right now though, I have all of my old settings re-enabled. I have the comms hub plugged into my batteries (for the centralized display). but the insight is plugged direct into the top battery in my bank. And it's been good for over an hour so far. So, I suspect I've found the "what", but not the "why"
When I get the new insight, I'll try it. if it exhibits the same issue, I'll contact SS and let them know so they may be able to lab it up and see if they have the same issue.
