question

Hi @SolalaSolar

In 'Vicron-speak' (a generally accepted standard)..

..Bulk is a transitional stage on the way to the Absorb target. There's no setting for it.

..Absorb is the maximum V that's targeted on a normal cycle. Akin to your 14.8V, but that's quite an aggressive level.

..Float is after Absorb is finished (the same in your case).

..Equalize is a maintenance procedure, not done daily, and you may decide not to use it at all. That'll be the 15.4V level you listed.

What you actually choose is largely dependent on what you're doing with your batts, cycling daily or largely as backup (Storage). And of course the batts themselves.

Bear in mind that Temperature Compensation will also apply, so the settings you choose will rise with cold batteries (and vice versa). If the maker doesn't provide their settings for that, then they aren't being fair, and the V settings they provide become 'shaky'.

Aggressive settings can cause longevity issues, and I prefer to take a softer approach. Usually the Victron defaults are fine, say 14.4 Abs/13.8 Float for non-specialized batts. You choose..

And yes, for 24V just double them.

Hi @JohnC!

Thank you for your time and answer! At this Point i have this Settings:

- Absorption Voltage 29,60

- Float Voltage 27,40

- Equalization Voltage 30,80

Here is a Screenshot of the manufacture Settings. Maybe you can See something there, but it‘s german. If necessary i can try to translate ist. Thank you again for your help!
