MultiPlus-II inverter/charger off-grid Australia
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 (14.4 V, temperature
compensated).
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.
Absorption
The absorption period is dependent on the bulk period. The maximum absorption time is the set Maximum Absorption time.
Float
Float voltage is applied to keep the battery fully charged
Storage
After one day of float charge the output voltage is reduced to storage level. This is 13,2 V. 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.
The voltage in th etable are for a 12V battery bank, to arrive at 48V battery bank voltages, multiply the 12V voltages by a factor
four.

9.6. Temperature compensation

Default output voltages for Float and Absorption are at 25 °C for 12V or 24V battery bank, to arrive at 48V battery bank voltages,
multiply the 24V voltages by a factor two.
Reduced Float voltage follows Float voltage and Raised Absorption voltage follows Absorption voltage. In adjust mode
temperature compensation does not apply.
