Dynoman IS the MAN!!!
To anyone who ever encounters this weird anomaly where a USER profile won't float -- Dynoman's note that the equalize charge interval must not be zero is 100% the cause (at least for mine.) Changing this to a nonzero is functionally irrelevant as the equalize charge time...
Hey mbour!
The problem with the DCC50s is that the boost time for the default Li profile is dashed out -- meaning it NEVER shuts off...so the boost recover of 13.2 is irrelevant as it is never reached until the MPPT production fades in the late afternoon/early evening production....which is why...
I appreciate the response and info -- I'll take another look at the settings and see if any of the gotchas you listed are the culprit.
Spamming the BMS's with full charge (boost) all day sure is a bummer...and really stupid...and I'd prefer not to can this charger.
I'll report back in case it...
I use the Renogy BT app instead of the DC Home -- it has more settings available....but it can be a bit clunky getting the dongle to connect.
Finally getting my USER profile to work if nothing else made me feel a lot better as I wasn't seeing 14.4 all day every day -- knowing Li really doesn't...
I used the default Li profile on my Renogy dcc50s for a year...and my batteries (2 SOK's and a Battleborn) all had their capacities drop by far more than I expected.
I replaced the SOK BMS's on warranty (they had old / wonky balancing logic)
I decided I needed to finally use a user profile...
Yep--that's the one. It is much more functional than "dc home."
Fortunately in my case -- it's all I need as my BMS's further manage my batteries themselves.
Cheers
Hey lebowski -- I posted my exact settings above. Hope they help -- the equalization interval not being zero was the irrelevant keys to the kingdom to get my Renogy to actually follow my custom values...Renogy can be so weird. :)
Cheers.

I can see the advantage of configuring the DCC50s to "ignore" the solar if you want the full alternator over just flipping a solar breaker -- which has been our approach since first installing ours a few years ago....meaning our DCC50s likely doesn't even have that option anyway :).
It's also...
