Custom Charge profiles not working - Yeti Pro 4000
I have been trying to use custom charge profiles on the Yeti Pro 4000, but it seems to keep ignoring them. For example, I set it to max charge 95%, min charge 15%, and start charging when it hits 90%. But the Yeti will run itself down to 0% sometimes (and then get stuck, and wont charge back up until I do a full reset). Or it will charge all the way up to 100%. Or it will ignore the recharge setting, and just keep running down the battery, even though solar panels are plugged in, and it should be charging back up - for instance, the other day it was down to 67%, even though it should have started charging at 90%. This doesn't happen every time, but maybe about 50% of the cycles it happens, so very frequently. The display on the Yeti shows that I have a custom charge profile enabled, and it's definitely still set in the app. As soon as switch back to one of the 3 default profiles, everything resumes functioning as normal.
Anyone else having the problem, or found a way to get them working properly? I've had this issue with two separate Yeti PRO 4000 units, so does not seem to be a problem with one specific unit.

I have the same problem with a 3000x. Sometimes have to cycle the power switch on the 600 watt charger. My 1500x has worked very well.

Same problem for me with the Pro 4000. The standard settings seem to work ok, just not the custom ones.

4000 running 1.7.7, same issue with custom profile: I had min charge set to 10%, and sometime overnight it went to 0% SOC. It also subsequently seems to have changed on its own from my custom profile to "Preformance". I'm going to leave it on Performance for a while so I can test out other scenarios without having to wonder if the custom charge profile is messing things up.

I have been experimenting and it seems that for me, the phone app is not sending the charge profile details to the Yeti. (app 4.3.0, Yeti 4000 FW 1.7.7)
If I set the profile to a predefined mode via the Yeti display, it takes effect and the app sees the change almost immediately. But if I set it on the phone (either to custom, or to some different predefined mode) the app continues to show what I set, but the battery doesn’t use it. Waiting some period of time (hours, days) doesn’t change that; the app shows what I set but the Yeti doesn’t match). If I view the profile on the Yeti display, the profile remains set as before. (I’m not certain yet, but merely viewing the profile on the display might refresh it back to the phone; tests in progress. I hadn’t been using the display at all for a while since the app seemed to be working well).So this might explain why it was always shutting off outputs at around 15% (battery saver minimum) instead of the 10% or other numbers I had set in the app.
At one point I did see a “USER” setting when cycling through the profiles on the display, so maybe it works sometimes, but that hasn’t appeared in the list for a while despite trying to set custom values over several days. I haven’t found a pattern to it yet.

Update:
It seems to be a one-way issue, possibly a bug in the latest app version? If you set the charge profile in the phone app, it is apparently not pushed to the Yeti. At this point, simply viewing the current setting on the Yeti display doesn’t change what the phone app shows, I guess the Yeti side doesn’t know the app value was changed. If you change the profile setting using the Yeti display, then it refreshes the phone app to match. If the phone is off or out of range, the app will automatically update the setting the next time it connects to the Yeti to show the Yeti profile setting, presumably because the Yeti knows there was a pending change not yet sent to the app.
I haven’t seen a way to set a custom profile directly on the Yeti 4000.
I’ll report this as a defect to get a formal response. Since I saw a USER custom setting on the Yeti display in the past, it might have worked using an earlier app version, or there is some other explanation. This does work OK with our Yeti 1500X and the same phone app version
