Orion-Tr Smart 12/12-30 Tail Current

Though I have a strong desire to start a rant about design flaws of the Orion such as not being that smart without VE networking or because it’s configuration is lacking of several parameters, please, community and/or experts try to answer my simple question based on the common experience, that the Orion switches way too early from Absorption to Float:


WHAT IS THE FCKN TAIL CURRENT HARD CODED TO IT?


If I‘m not able to configure it myself, I at least want to configure MPPT and BMV to interpret data the same way.


TIA

Might it be the tail current is at around 4-5A fixed? I will try to monitor that few more times to check if there’s a common pattern. With my 90Ah GEL 4.6A is way to high, as far as I‘m concerned.

Hi @cstenger

Where did you see that it uses 'Tail' to decide? If it used that then there would be a setting in the app.

I think your choice is between a Fixed absorb time, and Adaptive, which takes a proportion of the max abs time, dependent on what V the battery shows when the charger starts.

Hi @JohnC


well, that was at least my assumption as the MPPT works that way. Of course Charged Voltage would be the second parameter required to be configurable.


My Absorption Time is set to Adaptive. If the battery nearly full, the Orion switches to Float at lower current, around 1-2A, because Absorption started at lower current already. In that scenario, the current hardly drops in Absorption phase. Hence I'm wondering why it doesn't keep charging when coming from a lower SoC until it reaches about the same current as for higher SoC.
