14.5. Appendix E: Charge Characteristic
14.5.1. 4-stage charging:
Bulk Entered when charger is started. Constant current is applied until nominal battery voltage is reached, depending on temperature and input voltage, after which constant power is applied up to the point where excessive gassing is starting (28.8 V resp. 57.6 V, temperature compensated).
14.5.2. Battery Safe
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.
14.5.3. Absorption
The absorption period is dependent on the bulk period. The maximum absorption time is the set Maximum Absorption time.
14.5.4. Float
Float voltage is applied to keep the battery fully charged
14.5.5. Storage
After one day of float charge the output voltage is reduced to storage level. This is 26,4 V resp. 52,8 V (for 24 V and 48 V charger). 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 = one hour) to ’refresh’ the battery.
14.6. Appendix F: Temperature Compensation
Default output voltages for Float and Absorption are at 25 °C. Reduced Float voltage follows Float voltage and Raised Absorption voltage follows Absorption voltage. In adjust mode temperature compensation does not apply.
