2. DESCRIPTION
2.1 General
Multi Compact -functional
The MultiPlus Compact gets its name from the multiple functions it can perform. It
is a powerful true sine wave inverter, a sophisticated battery charger that features
adaptive charge technology and a high-speed AC transfer switch in a single
compact enclosure. Beside these primary functions, however, the MultiPlus
Compact has several advanced features that provide a range of new applications
as outlined below.
Uninterrupted AC power
In the event of a grid failure, or shore or generator power being disconnected, the
inverter within the Multi Compact is automatically activated and takes over supply
to the connected loads. This happens so fast (less than 20 milliseconds) that
computers and other electronic equipment will continue to operate without
disruption.
PowerControl – Dealing with limited generator or shore side power
With a Phoenix Multi Control Panel a maximum generator or shore current can be
set. The Multi Compact will then take account of other AC loads and use
whatever is extra for charging, thus preventing the generator or shore supply
from being overloaded.
PowerAssist – Boosting the capacity of shore or generator power
This feature takes the principle of PowerControl to a further dimension allowing the
MultiPlus Compact to supplement the capacity of the alternative source. Where peak
power is so often required only for a limited period, it is possible to reduce the size of
generator needed or conversely enable more to be achieved from the typically limited
shore connection. When the load reduces, the spare power is used to recharge the
battery.
2.2 Battery charger
Adaptive 4-stage charging characteristics: bulk – absorption – float – storage
The microprocessor-driven adaptive battery management system can be adjusted for various
types of batteries. The adaptive function automatically adapts the charging process to battery
use.
The right amount of charge: variable absorption time
In the event of slight battery discharge, absorption is kept short to prevent overcharging and
excessive gas formation. After deep discharging, the absorption time is automatically
extended in order to fully charge the battery.

4
Preventing damage due to excessive gassing: the BatterySafe mode
If, in order to quickly charge a battery, a high charge current in combination with a high
absorption voltage has been chosen, damage due to excessive gassing will be prevented by
automatically limiting the rate of voltage increase once the gassing voltage has been
reached.
Less maintenance and aging when the battery is not in use: the Storage mode
The Storage mode kicks in whenever the battery has not been subjected to discharge during
24 hours. In the Storage mode float voltage is reduced to 2,2V/cell (13,2V for 12V battery) to
minimise gassing and corrosion of the positive plates. Once a week the voltage is raised
back to the absorption level to ‘equalize’ the battery. This feature prevents stratification of the
electrolyte and sulphation, a major cause of early battery failure.
Two DC outputs for charging two batteries
The main DC terminal can supply the full output current. The second output, intended for
charging a starter battery, is limited to 4A and has a slightly lower output voltage.
Increasing service life of the battery: temperature compensation
The temperature sensor (supplied with the product) serves to reduce charging voltage when
battery temperature rises. This is particularly important for maintenance-free batteries, which
could otherwise dry out by overcharging.
More on batteries and charging
Our book ‘Energy Unlimited’ offers further information on batteries and battery charging, and
is available free of charge on our website (see www.victronenergy.com -> Support &
Downloads’ -> General Technical Information). For more information on adaptive charging,
please also refer to the General Technical Information our website.
2.3 Self consumption – solar energy storage systems
When the Multi/Quattro is used in a configuration in which it will feed back energy to the grid
it is required to enable grid code compliance by selecting the grid code country setting with
the VEConfigure tool.
This way the Multi/Quattro can comply to the local rules.
Once set, a password will be required to disable grid code compliance or change grid code
related parameters.
If the local grid code is not supported by the Multi/Quattro an external certified interface
device should be used to connect the Multi/Quattro to the grid.
Special note for Australian customers: IEC62109.1 certification and CEC approval for off-grid
use does NOT imply approval for grid-interactive installations. Additional certification to IEC
62109.2 and AS 4777.2.2015 are required before grid-interactive systems can be
implemented. Please check Clean Energy Council website for current approvals.

3. OPERATION
3.1 On/Off/Charger Only Switch
When switched to "on", the product is fully functional. The inverter will come into
operation and the LED "inverter on" will light up.
An AC voltage connected to the "AC in" terminal will be switched through to the
"AC out" terminal, if within specifications. The inverter will switch off, the "mains
on" LED will light up and the charger commences charging. The "bulk",
"absorption" or "float" LEDs will light up, depending on the charger mode.
If the voltage at the "AC-in" terminal is not within specifacations, the inverter will
switch on.
When the switch is switched to "charger only", only the battery charger of the
Phoenix Multi will operate (if mains voltage is present). In this mode input voltage
also is switched through to the "AC out" terminal.
NOTE: When only the charger function is required, ensure that the switch is
switched to "charger only". This prevents the inverter from being switched on if
the mains voltage is lost, thus preventing your batteries from running flat.
3.2 Remote control
Remote control is possible with a 3-way switch or with a Multi Control panel.
The Multi Control panel has a simple rotary knob with which the maximum current
of the AC input can be set: see PowerControl and PowerAssist in Section 2.
For the appropriate DIP switch settings, see sect. 5.5.1.
3.3 Equalisation and forced absorption
3.3.1 Equalisation
Traction batteries may require regular equalisation charging. In the equalisation mode,
the MultiPlus will charge with increased voltage for one hour (1V above the absorption
voltage for a 12V battery, 2V for a 24V battery). The charging current is then limited to
1/4 of the set value. The “bulk” and “absorption” LEDs flash intermittently.
Equalisation mode supplies a higher charging voltage than most DC
consuming devices can cope with. These devices must be disconnected
before additional charging takes place.
3.3.2 Forced absorption
Under certain circumstances, it can be desirable to charge the battery for a fixed time
at absorption voltage level. In Forced Absorption mode, the MultiPlus will charge at the
normal absorption voltage level during the set maximum absorption time. The “absorption”
LED will be ‘on’.

6
3.3.3 Activating equalisation or forced absorption
The MultiPlus can be put into both these states from the remote panel as well as with the
front panel switch, provided that all switches (front, remote and panel) are set to “on” and no
switches are set to “charger only”.
In order to put the MultiPlus in this state, the procedure below should be followed.
If the switch is not in the required position after following this procedure, it can be switched
over quickly once. This will not change the charging state.
NOTE: Switching from “on” to “charger only” and vice versa, as described below, must be done quickly.
The switch must be toggled such that the intermediate position is 'skipped', as it were. If the switch
remains in the “off” position even for a short time, the device may be turned off. In that case, the
procedure must be restarted at step 1. A certain degree of familiarisation is required when using the front
switch on the Compact in particular. When using the remote panel, this is less critical.
Procedure:
1. Check whether all switches (i.e. front switch, remote switch or remote panel switch if present)
are in the “on” position.
2. Activating equalisation or forced absorption is only meaningful if the normal charging cycle is
completed (charger is in 'Float').
3. To activate:
a. Switch rapidly from “on” to “charger only” and leave the switch in this position for ½ to 2
seconds.
b. Switch rapidly back from “charger only” to “on” and leave the switch in this position for ½ to
2 seconds.
c. Switch once more rapidly from “on” to “charger only” and leave the switch in this position.
4. On the MultiPlus the three LEDs “Inverter”, “Charger” and “Alarm” will now flash 5 times.
If a MultiControl panel is connected, on the panel the LEDs “bulk”, “absorption” and “float” will
also flash 5 times.
5. Subsequently, on the MultiPlus the LEDs “Bulk”, “Absorption” and “Float” will each light during
2 seconds.
If a MultiControl panel is connected, on the panel the LEDs “bulk”, “absorption” and “float” will
also each light during 2 seconds.
6. a. If the switch on the MultiPlus is set to “on” while the “Bulk” LED lights, the charger will switch
to equalisation.
Similarly, if the switch on the MultiControl panel is set to “on” while the “Bulk” LED lights, the
charger will switch to equalisation.
b. If the switch on the MultiPlus is set to “on” while the “Absorption” LED lights, the charger will
switch to forced absorption.
Similarly, if the switch on the MultiControl panel is set to “on” while the “Absorption” LED lights,
the charger will switch to forced absorption.
c. If the switch on the MultiPlus is set to “on” after the three LED sequence has finished, the
charger will switch to “Float”.
Similarly, if the switch on the MultiControl panel is set to “on” after the three LED sequence
has finished, the charger will switch to “float”.
d. If the switch is has not been moved, the MultiPlus will remain in ‘charger only’ mode and
switch to “Float”.
