I have an Orion-Tr Smart 12/24-10 Isolated (firmware v1.17) charging a 24V AGM thruster bank (2 x Exide Dual AGM EP450 in series) from a 12V LiFePO4 house bank.
The Orion is permanently powered and remains enabled continuously. Charging settings are:
-
Absorption voltage: 28.8V
-
Float voltage: 27.0V
-
Re-bulk voltage offset: 0.1V
-
Adaptive absorption: Enabled
-
Max absorption time: 2h
Once the charger has completed a charge cycle and entered Float, it does not appear to re-enter Bulk automatically.
If I disable and re-enable the charger, it immediately starts a new charging cycle and enters Bulk, later reaching Absorption at 28.8V.
My question is:
Should the Orion automatically re-enter Bulk when the battery voltage falls below the Float voltage minus the configured Re-bulk Voltage Offset?
I am concerned that the AGM battery bank may not periodically receive an Absorption charge unless the charger is manually restarted.
