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 (800VA and 1200VA

models only)

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.

EN NL FR DE ES IT Appendix

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 1A 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 3 position 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.

For the appropriate DIP switch settings, see sect. 5.4.1.

Note concerning firmware versions <=xxyy466:

When combined with a VE.Bus smart dongle, CCGX, Venus GX or alike, the Main

"on/off/charger-only" switch will have limited functionality.

The main switch can always be used to switch the Multi off. However, in order to switch the

Multi back on while the unit is connected to a live AC input, not only the main switch should be

switched into the "on" position, thereafter the actual "on" action should be initiated through the

user interface switch. This can for example be directly by means of the CCGX screen and

controls, through remote console on VRM, or in case of the "VE.Bus smart dongle" through

"VictronConnect".

This behavior is fixed in firmware version xxyy467.

a. Excessively high ambient temperature will result in the following:

- Reduced service life.

- Reduced charging current.

- Reduced peak capacity, or shutdown of the inverter.

b. Never mount the product directly above the batteries.

Procedure

Proceed as follows to connect the battery cables:

Use an insulated box spanner in order to avoid shorting the battery.

Avoid shorting the battery cables.

Connect battery cables to the Multi and battery, see appendix A.

Reverse polarity connection will cause damage to the product. (Safety fuse inside the Multi

can be damaged).

Use PZ 2 screwdriver for Multi 500/800VA and 24V/48V 1200VA.

Use Flatscrewdriver 6.5mm for Multi 12V 1200VA.

Internal DC Fuses

All servicing must be undertaken by qualified personnel.

4.3 Connection of the AC cabling

The Multi is provided with a ground relay (relay H, see appendix B) that automatically

connects the Neutral output to the chassis if no external AC supply is available. If an

external AC supply is provided, the ground relay H will open before the input safety relay

closes. This ensures the correct operation of an earth leakage circuit breaker that is

connected to the output.

- In a fixed installation, uninterruptable grounding can be secured by means of the grounding

wire of the AC input. Otherwise the casing must be grounded.

- In a mobile installation, interrupting the shore connection will simultaneously disconnect the

grounding connection. In that case, the casing must be connected to the chassis (of the

vehicle) or to the hull or grounding plate (of the boat).

- In case of a boat, direct connection to the shore ground is not recommended because of

potential galvanic corrosion. The solution to this is using an isolation transformer.

The mains input & output terminal connector can be found on the bottom of the Multi, see

appendix A. The shore or mains cable must be connected to the connector with a three-wire

cable. Use a three-wire cable with a flexible core and a cross section of at least 1.5mm².
