Figure 1: Adaptive charging:
Bulk-mode: Entered after a reset or if the battery voltage becomes 1.3V resp. 2.6V (for 12V and 24V
charger) lower than Float voltage. Constant current is applied until the battery has reached 14.4V
resp. 28.8V (for 12V and 24V charger, temperature compensated).
Battery Safe mode: The applied voltage to the battery is raised gradually until the set Absorption
voltage is reached. The Battery Safe Mode is part of the calculated absorption time.
Absorption-mode: Absorption voltage is applied until {actual-Bulk-Ah*5 / max.adjusted-Bulk-current}
(in hours) is reached. Usually {actual-Bulk-Ah*5} = {max.adjusted-Bulk-current * Bulk-hours *5}, but
the actual-Bulk-current can be limited by ambient temperature, or remote-control.The maximum time
in Absorption mode is the Maximum Absorption time set with control panel.
Float-mode: Float voltage is applied to keep the battery fully charged and to protect it against self
discharge. After one day of Float charge a reduced Float charge is applied. This is 13V resp. 26V
(for 12V and 24V charger, temperature compensated). This will limit water loss to a minimum when
the battery is stored for the winter season.
After an adjustable time (default = 7 days) the charger will enter Repeated Absorption-mode for an
adjustable time (default = 4 quarters ).
