6000xp bug in charge controller setpoint voltages with open loop

I have snow showers happening today and for the next 2 days, and may or may not get a full charge by the end of the day.... I'll capture and post the next good data set confirming whether the current settings result in proper charge behavior or not.

Sun came out today and charged system to full.... verifying that the charge curve is NOT doing what I programmed. The 6000xp is holding end-of-charge voltage (56v) for three hours rather than dropping to float at 54.0 right after hitting EOC voltage as programmed.

The 6000xp charge firmware really needs a patch for best performance and longest life from LFP batteries.

Correct CC/CV charge for LFP should charge at a max current possible to float voltage, then CV to end of charge voltage, then immediately drop to maintain at float voltage..... and reset overnight (indicated by zero PVinput for more than 4 hours OR by voltage dropping to ACchargestart or GeneratorChargeStart voltage).

This issue should not be closed until patch is available, available for download/update, and documentation and release notes have been distributed to ALL registered 6000xp accounts.

I have FINALLY found a combination of charge voltage setpoints that appear to give a "correct" CC-CV charge curve for LFP. I think EG4 still needs to dig into why it is so hard to get a LFP charge curve if you want open loop communication, and they definitely need to document these settings as an example to help people understand how to program a LFP-friendly curve.

batt type= lead-acid

amp-hrs= xxx

Vcharge= 56.2

Vfloat=54.0

Veq=54.4 , days=0, time=0

system reverted to "bad behavior" for some reason.... floating at charge voltage ?! really, really, really NOT what I want. When can we expect to see a firmware update that fixes this reliably ?

I wouldn't have gotten the eg4 6000XP had I known it was so wonky with charging lithium batteries. Hopefully a firmware update fixes this.
