1 DESCRIPTION
1.1 General
Multi Compact -functional (Multi Compact / MultiPlus Compact only)
The Multi 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 Multi Compact has several advanced features that provide a
range of new applications as outlined below.
Uninterrupted AC power (Multi Compact / MultiPlus Compact only)
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 (Multi Compact/
MultiPlus Compact only)
The Multi Compact is a very powerful battery charger. It will therefore draw a lot of current
from the generator or shore side supply (nearly 5 A per Multi Compact at 230 VAC). With the
Phoenix Multi Control (PMV) 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
The feature that distinguishes the Phoenix MultiPlus Compact from the standard Multi
Compact is PowerAssist. 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.
Note 1: The rating of the generator should be 75% or higher compared to the VA rating of the
MultiPlus Compact. (for ex: a genset of at least 900 VA will be required to operate in parallel
with a Multi Compact 12/1200/50.
Note 2: The output waveform of a generator can be heavily distorted. In that case the “AC
waveform check” should be disabled. See page 20.

1.2 Battery Charger (Multi Compact / MultiPlus Compact only)
Adaptive 4-stage charge characteristic: bulk – absorption – float – storage
The Phoenix Multi Compact / MultiPlus Compact features a microprocessor controlled
‘adaptive’ battery management system that can be preset to suit different Typs of batteries.
The ‘adaptive’ feature will automatically optimize the process relative to the way the battery is
being used.
The right amount of charge: variable absorption time
When only shallow discharges occur (a yacht connected to shore power for example) the
absorption time is kept short in order to prevent overcharging of the battery. After a deep
discharge the absorption time is automatically increased to make sure that the battery is
completely recharged.
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, the Multi Compact / MultiPlus Compact will prevent
damage due to excessive gassing 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 2,2 V/cell (13,2 V for a 12 V battery)
to minimize 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 outputs to charge 2 battery banks
The Multi Compact / MultiPlus Compact features 2 outputs, of which 1 can carry the full
output current. The second output, limited to approximately 4A and with a slightly lower
output voltage, is intended to top up a starter battery.
To increase battery life: temperature compensation
Every Multi Compact / MultiPlus Compact comes with a battery temperature sensor. When
connected, charge voltage will automatically decrease with increasing battery temperature.
This feature is especially recommended for sealed batteries and/or when important
fluctuations of battery temperature are expected.

2 OPERATION
2.1 On/Off/Charger Only Switch
When the front switched to "on", the product is fully functional. The inverter will come into
operation and the LED "inverter on" will light up.
Multi Compact/ MultiPlus Compact only:
An AC voltage connected to the "AC in" connector will be switched through to the "AC out"
connector, if within specifications. The inverter will switch off, the "charger" LED will light up
and the charger commences charging. The "charger" LED will light up depending on the
charger mode (on=bulk, absorption) or (blinks=float).
If the voltage of the "AC-in" terminal is too high or too low, the AC input voltage will switch off
and the inverter will be starting.
When the front switch is switched to "charger only", only the battery charger of the Phoenix
Multi Compact 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.
2.2 Remote Operation
The Phoenix Multi Compact can be operated with the Phoenix Multi control panel. The
remote control has an on-off switch and more indication.
The charger of the Phoenix Multi Compact can be turned off. This can be done by changing
the set up configuration by connecting the Phoenix Inverter remote control (set the AC input
current to 0) or by connecting a computer to the Phoenix Multi Compact (use MK.1 with
VEConfigure).
For remote control of the Phoenix Inverter Compact the Phoenix Inverter control panel
should be used.
2.3 Special Charger Modes Equalizing
Some batteries may need a regular equalizing charge. To perform an equalizing charge the
Phoenix Multi Compact can charge at a higher voltage (1V above the absorption voltage for a
12V battery, 2V for a 24V battery) for a period of one hour. The charger current is then limited
to 1/4 of the specified value.
The "bulk" and "absorption" LEDs will flash alternately during this cycle (only on Phoenix Multi
Control).
The equalizing mode results in a charging voltage that may exceed the
maximum voltage of DC consumers. These should be disconnected when
performing an equalizing charge.

6
Forced Absorption
In some cases it may be necessary to charge the battery at the absorption voltage for a
specific period of time. In the Forced Absorption mode, the Phoenix Multi Compact will
charge at the normal absorption voltage during the preset maximum absorption period.
The "absorption" LED will light up (only on Phoenix Multi Control).
The Phoenix Multi Compact can be switched to one of these modes from the remote control
as well as with the aid of the front switch. A prerequisite is that all switches (front, remote,
remote Control) are switched to "on", and that none are switched to the "charger only"
position.
Proceed is as follows to switch the Phoenix Multi Compact to either the equalizing mode or
Forced Absorption mode:
REMARK: switch quickly from "on" to "charger only" and back. The switch must be switched
in such a way that the intermediate position is, as it were, "skipped". If the relevant switch
remains in the "off" position for any length of time, you may run the risk that the appliance will
be switched off. In that case you will need to start again. Use a remote control for best
results.
1. Ensure that all switches (i.e., front switch, remote or remote control switch if
present are switched to the "on" position).
2. Ensure that the Phoenix Multi Compact is charging (an AC input voltage must be
present; check that the "charger" LED is one (only remote control: "mains", of
either the "bulk", "absorption" or "float" LEDs is illuminated).
3. Switch the switch successively to "charger only", "on" and "charger only". NOTE:
the switching itself should be done quickly but the interval between switching
should be from 1/2 to two seconds.
4. The "green front-led =bulk", "yellow front-led=absorption" and "red-front
led=float" LEDs will flash five times (only remote control the "bulk", "absorption" and
"float" LEDs will flash five times.
•Subsequently, the "green front led=bulk", "yellow front led=absorption" and
"red front led=float" LEDs will each light up for a period of two seconds.
•If the switch is switched to "on" while the "green front led=bulk" LED
illuminates, the charger switches to the equalizing mode.
•If the switch is switched to "on" while the "yellow led=absorption" LED
illuminates, the charger switches to 'Forced Absorption'
If the switch is not in the required position after these steps, it can be simply switched one
more time. This will not change the charging status.

3.5 Connection of the AC cabling
This is a Safety Class I product (supplied with a protective grounding terminal).
Uninterruptible protective grounding must be provided at the AC input
and/or output terminals and/or chassis grounding point located externally
on the product. See the following instructions:
a) The Phoenix Inverter Compact has a free floating AC output. The grounding
point located externally on the product must be used to ground the chassis.
The neutral output wire must be connected to ground to ensure proper
functioning of a GFCI (Ground Fault Circuit Interrupter).
b) Phoenix Multi / MultiPlus Compact : the output neutral wire will
automatically be bonded to the chassis (with the output ground relay, see
appendix 2) when no external AC source is available (backfeed / safety relay
open and product running in inverter mode, see appendix 2).When an external
AC source is provided, the ground relay opens before closure of the backfeed /
safety relay. Once closed, the backfeed / safety relay ensures that the neutral to
ground bond is provided by the external AC source. This is to ensure proper
functioning of a GFCI to be installed in the AC output of the Multi/MultiPlus.
- In a fixed (for example terrestrial) installation an uninterrupted chassis ground
may be provided by the AC input ground wire.
- In case of a mobile installation (connection to input AC with a shore power
cord), the ground connection is lost when the shore power cord is unplugged. In
this case the chassis of the product or the on - board section of the input ground
wire must be connected to the frame (of the vehicle) or the ground plate or hull
(of a boat).
- Marine applications: due to the potential for galvanic corrosion it is in general
not acceptable to connect the shore side ground to the ground plate or hull of
the boat. The proper and safe solution is to install an isolation transformer.
The mains -input & output terminal connector G-ST18i can be found on the bottom of the
Multi Compact, see appendix 1. The shore or mains cable must be connected to the G-ST18i
connector with a three-wire cable. Use a three-wire cable with a flexible core and a cross
section of 1.5 mm² (800VA) to 2.5 mm² (1600VA).
Procedure
Proceed as follows to connect the AC cables:
The AC output cable can be connected directly to the G-ST18i male-connector. (the
connector pulls out!)
The terminal points are indicated clearly. From left to right: “N” (neutral), earth, and “L1”
(phase).
The AC input cable can be connected directly to the G-ST18I female-connector. (the
connector pulls out!)
The terminal points are indicated clearly. From left to right: “L1” (phase). earth, and “N”
(neutral),
Push the G-ST18i "input" connector into terminal connector (near to rear-side).
Push the G-ST18i "output" connector into terminal connector (near to front-side).

1The optimal absorption voltage for flat plate lead acid batteries is subject to mechanical and chemical
properties. Batteries with high antimony content can typically be charged with a lower absorption voltage
than batteries with low antimony content. (Please refer to our book “Electricity on Board” downloadable
from our website www. victronenergy.com for details and suggestions about charging batteries). Contact
your battery supplier for the correct charge voltages and change (with VE-configure) the voltage settings if
required. The default charge current setting is 75% of the maximum charge current. This current will be too
high for most applications. For most battery Types the optimal charge current is 0.1-0.2x the battery
capacity.
