2. DESCRIPTION
2.1 General
Multifunctional
The Multi 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 enclosure. Beside these primary functions,
however, the Multi 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 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.
Parallel and 3-phase operation capability
Up to 6 inverters can operate in parallel to achieve higher power output.
Operation in 3-phase configuration is also possible.
PowerControl – Dealing with limited generator or shore side power
With a Multi Control Panel a maximum generator or shore current can be set. The Multi 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.
Programmable relay
The Multi is equipped with a programmable relay that by default is set as an alarm relay. The
relay can be programmed for all kinds of other applications however, for example as a starter
relay for a generator.
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 2,2 V/cell (13,2 V for 12 V 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 1 A 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 on our website.
2.3 Self consumption – solar energy storage systems
When the Multi 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.
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 an external certified interface device should
be used to connect the Multi to the grid.

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 ‘Charger’ LED will light up
and the charger commences charging. If the voltage at the ‘AC-in’ terminal is not within
specifications, the inverter will switch on.
When the switch is switched to ‘charger only’, only the battery charger of the Multi will
operate (if mains voltage is present). In this mode input 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 the batteries from running flat.
3.2 Remote control
Remote control is possible with a 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 in Section 2.
