6000XP Not going to float. Just me?

My 2 new 6000XPs are set to charge at 56.2V and 54.0V for float. No battery comm. Firmware is the latest.
They get to 56.2V and then stay there until the sun goes down. They never go to 54V.
It is damaging to the batteries to have them stay at the high V once full. That's why we switch to a lower float V.

Does anyone else with 6000XPs have this problem or is it just my 2 units?

Sig Solar is looking into this.

Thanks.

Feel free to send me a DM of the inverters serial number and I can look into this.

Has anyone else with a 6000XP seen this? Or even checked their system for it?

I have never seen float either. I am using the JK inverter BMS with coms.
The BMS has a requested float and charge voltage setting and it still doesnt work.

If you get this figured out please post it up here. I have a luxpowertek sna 6000(6000xp sans breakers) with 2 non coms batteries. I have yet to hook up PV and would love to hear what becomes of this. Thanks.

Might be late in replying, but the reason is, all inverter based on Voltronic design ignores the float voltage command in BMS communication mode.

There is only CV charging mode (no float mode) plus the 95% - 100% SOC charging rinse repeat.

In voltage based control mode, you need to have 2Volt differential between the CV and Float.
