Quattro 48/8000 stays in absorption with Pylontech US3000

Good day,

I just want to make sure if this is normal or not...


I have set up everything to the dot from the steps here:

https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom


But what I see is after 48 hours with constant AC-in, the Quattro still stays absorption:

I never saw that it went to float, only see it in absorption...

  • Quattro is newest firmware
  • Venus GX is newest firmware


Is this normal?

Thanks!

Hi @Goose

See faq Q7:

https://www.victronenergy.com/live/ess:design-installation-manual#faq


While discharging, and connected to the grid, the state can still show a charge state, such as Bulk, Absorption or Float. Even though it is not charging. This is normal, nothing to worry about.

Thank you for this, but I currently do not have ESS configured, only DVCC for Grid Backup.

Does the same argument apply?
