4.4 Setting the Charger (Multi Compact / MultiPlus Compact only)
4.4.1 Preprogrammed charge curves (can be changed with VEConfigure only).
Please refer to our book "Electricity on Board" downloadable from our website
www.victronenergy.com for details and suggestions about charging batteries.
The Phoenix Multi Compact/ MultiPlus Compact has 3 pre-programmed charge curves:
Fixed, 3 state charge curve
The absorption period is a fixed preset period. Following the absorption mode, the charger
switches to float. In order to "refresh" the battery, the charger periodically switches back to
absorption.
Adaptive charge curve
The absorption period depends on the length of the bulk charge period (see par. 4.3). This is
followed by a float phase lasting 24 hours, after which the voltage is reduced by an additional
0,8 V resp. 1,6 V for 12 V resp. 24 V batteries (reduced float). As with the Fixed-charge
curve, the charger will periodically switch back to absorption.
Adaptive charge curve with BatterySafe mode (default setting)
If, in order to quickly charge a battery, a high charge current in combination with a high
absorption voltage has been chosen, the Phoenix charger will prevent damage due to
excessive gassing by automatically limiting the rate of voltage increase once the gassing
voltage has been reached.

4.4.2 Other settings

Absorption time (default: 4 hours)
The Absorption setting defines the fixed absorption period in the case of the fixed charge
curve, and the maximum absorption time in the case of the adaptive charge curve.
The (maximum) absorption time can be set from 1 to 8 hours.
Float Voltage (default: 14.4V / 28.8V)
The float voltage can be set from 12V to16V, respectively from 24V to 32V, in 0.05V
increments.
Repeated Absorption
When in float, the charger will periodically switch back to Absorption to "refresh" the battery.
Repeated Absorption Time (default: 1 hour)
The repeated absorption time can be set from 1 to 72 quarters of an hour.
Repeated Absorption Interval (default: 7 days)
The repeated absorption interval can be set from 1 to 45 days.
