I commissioned my 6000xp and its connected to eg4 powerpro battery a month ago. EG4 monitor is set to "Lithium" battery and com set to "0:EG4" so im using SOC% and not setting absorb/float voltages. The online XP Monitor can read the battery stats. Where are the charge settings coming from, the XP or the powerpro? Because the powerpro document recommend settings are 56.2v bulk/absorb and 54v float. Buts it not doing that, is maxing out at 54v and floating at 53.4v and saying its 100% SOC. So 54V is now 100%?

You might need to top balance the battery cells. I would recommend charging by voltage for a few days then switching it back to SOC. You would have to set the battery type to "Lead-Acid" and set the absorb/bulk to 56.2, float to 54V and the low DC cutoff to 47V.

In progress, doing it remotely!
 
OK, doesn't seem to be working. On 2 separate 3 day long stents I set up 6000xp as Lead acid to top balance, bulk 56.2v and Float 54v. It followed the lead acid voltages just fine. When going back to Lithium-SOC mode its still barely getting over 54v for bulk and floating around 53.5v. So how to run in Lithium-SOC mode and get the recommended 56.2v bulk and 54v float?

So how do I get SOC mode to hit the correct bulk and float voltages? I don't see these settings on the battery display.
 
Interesting that once you hit 100% SOC it doesn’t keep the voltage up to balance the batteries. Either you’re hitting a cell OVP or the inverter is acting like what’s happening in the threads with Pylontech CAN protocol where the 6000xp and Lux branded version just stops charging and ignoring RCV from BMS.

No faults or errors so cells ok. I'm using the CAN connection. Do I need to switch to RS485?

I’m not sure on the EG4 batteries. Several of us have very balanced DIY batteries and the JK and SEPLOS BMS are doing something similar where once SOC hits 100%, RCV is ignored for some reason.
