2. DESCRIPTION

2.1 In general

The basis of the MultiPlus is an extremely powerful sine inverter, battery charger and automatic switch in a compact casing. The MultiPlus features the following additional, often unique characteristics:

Automatic and uninterruptible switching

In the event of a supply failure or when the generating set is switched off, the MultiPlus will switch over to inverter operation and take over the supply of the connected devices. This is done so quickly that operation of computers and other electronic devices is not disturbed (Uninterruptible Power Supply or UPS functionality). This makes the MultiPlus highly suitable as an emergency power system in industrial and telecommunication applications. The maximum alternating current that can be switched is 16A or30A, depending on model.

Virtually unlimited power thanks to parallel operation

Up to 6 Multi’s can operate in parallel. Six units 24/3000/70, for example, will provide 15kW / 18kVA output power and 420 Amps charging capacity.

Three phase capability

Three units can be configured for three-phase output. But that’s not all: up to 6 sets of three units can be parallel connected to provide 45kW / 54kVA inverter power and more than 1000A charging capacity.

PowerControl – maximum use of limited shore current

The MultiPlus can supply a huge charging current. This implies heavy loading of the shore connection or generator set. Therefore a maximum current can be set. The MultiPlus then takes other power users into account, and only uses 'surplus' current for charging purposes.

PowerAssist – Extended use of your generator and shore current: the MultiPlus “co-supply” feature

This feature takes the principle of PowerControl to a further dimension allowing the MultiPlus to supplement the capacity of the alternative source. Where peak power is so often required only for a limited period, the MultiPlus will make sure that insufficient shore or generator power is immediately compensated for by power from the battery. When the load reduces, the spare power is used to recharge the battery.

This unique feature offers a definitive solution for the ‘shore current problem’: dish washers, washing machines, electric cooking etc. can all run on 16A shore current, or even less. In addition, a smaller generator can be installed.

Solar energy

The MultiPlus is extremely suitable for solar energy applications. It can be used in autonomous systems as well as grid connected systems.

Autonomous operation when the grid fails

Houses or buildings with solar panels or a combined micro-scale heating and power plant or other sustainable energy sources have a potential autonomous energy supply which can be used for powering essential equipment (central heating pumps, refrigerators, deep freeze units, Internet connections, etc.) during a power failure. A problem is however that grid connected sustainable energy sources drop out as soon as the grid fails. With a MultiPlus and batteries, this problem can be solved in a simple manner: the MultiPlus can replace the grid during a power failure. When the sustainable energy sources produce more power than needed, the MultiPlus will use the surplus to charge the batteries; in the event of a shortfall, the MultiPlus will supply additional power from the battery.

Multi-functional relay

The MultiPlus is equipped with a multi-functional relay that by default is programmed 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.

Programmable with DIP switches, VE.Net panel or personal computer

The Phoenix Inverter is supplied ready for use. Three features are available for changing certain settings if desired: ─ The most important settings (including parallel operation of up to three devices

and 3-phase operation) can be changed in a very simple manner, using DIP switches.

─ All settings, with exception of the multi-functional relay, can be changed with a

VE.Net panel.

─ All settings can be changed with a PC and free of charge software,

2.2 Battery charger

Adaptive 4-stage charge characteristic: bulk – absorption – float – storage

The MultiPlus features a microprocessor controlled ‘adaptive’ battery management system that can be preset to suit different types of batteries. The ‘adaptive’ feature will automatically optimise 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.

EN NL FR DE ES Appendix

Preventing damage due to excessive gassing: the BatterySafe mode (see fig. 2 below)

If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, the MultiPlus will prevent damage due to excessive gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached (see the charge curve between 14,4V and 15,0V in fig. 2 below).

Less maintenance and aging when the battery is not in use: the Storage mode (see fig. 1 & 2 below)

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 outputs to charge 2 battery banks

The MultiPlus features 2 outputs, of which 1 can carry the full output current. The second output, limited to approximately 4 A and with a slightly lower output voltage, is intended to top up a starter battery.

To increase battery life: temperature compensation

Every MultiPlus 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.

Battery voltage sense

In order to compensate for voltage loss due to cable resistance the MultiPlus is provided with a voltage sense facility so that the battery always receives the correct charge voltage.

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 rejected, 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 Phoenix Multi Control panel. The Phoenix 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.

3.3 Equalisation and forced absorption

3.3.1 Equalisation

Traction batteries require regular additional 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 lights.

EN NL FR DE ES Appendix

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.

NOTE: Switching from “on” to “charger only” and vice versa, as described below, must be done quickly. The switch must be turned such that the intermediate position is 'skipped', as it were. If the switch concerned 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 in particular. When using the remote panel, this is less critical.

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'). Set the switch to “charger only”, “on” and “charger only” in rapid succession. NOTE: the switching operation itself must be done quickly, but the time between switching must lie between 1/2 second and 2 seconds.

3. The “bulk”, “absorption” and “float” LEDs will now flash five times. Subsequently, the “bulk”, “absorption” and “float” LEDs will each light for 2 seconds.

4. If switch is set to “on” while the “bulk” LED lights, the charger will be put into equalisation operation.

5. If switch is set to “on” while the “absorption” LED lights, the charger will be put into forced absorption operation.

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.

EN NL FR DE ES Appendix

4.5 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:

The MultiPlus: the output neutral wire will automatically be bonded to the chassis (with the output ground relay, see appendix) when no external AC source is available (backfeed / safety relay open and product

runnig in inverter mode, see appendix). 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 terminal block can be found on the printed circuit board, see Appendix 0. The shore or mains cable must be connected to the Multi with the aid of a three-wire cable. Use a three-wire cable with a flexible core and a cross section of 2.5 or 4 mm²

Procedure

Proceed as follows to connect the AC cables:

• The AC output cable can be connected directly to the terminal block "AC-out". From left to right: “PE” (earth), “N” (neutral) and “L” (phase).

• The AC input cable can be connected to the terminal block “AC–in”. From left to right: “PE” (earth), “N” (neutral) and “L” (phase).

4.6 Optional Connections

A number of optional connections are possible:

4.6.1 Second Battery

The MultiPlus has a connection for charging a starter battery. For connection see Appendix 0.

4.6.2 Voltage Sense

Two sense wires may be connected to compensate possible battery cable losses during charging. Use wires of at least 0.75mm2. For connection see Appendix 0.

4.6.3 Temperature Sensor

The temperature sensor supplied with the product may be used for temperaturecompensated charging (see Appendix 0). The sensor is isolated and must be mounted on the batteries minus pole.

4.6.4 Remote Control

The product can be operated remotely in two ways.

• With an external switch.

• With a Phoenix Multi Control panel.

For connection of the switch see Appendix 0. Observe the following when using an external switch:

• Only functions if the switch on the product is switched to the "on" position.

• Not to be connected if a remote control panel is connected.

For connection of the remote control panel, see Appendix 0. Observe the following when using a remote control panel:

• Only functions if the switch on the product is switched to the "on" position.

4.6.5 External Relay

The maximum current that can be switched through from the AC input to the AC output is 16 A (optional: 30 A). At more than 30 A an external contactor is needed: please consult your supplier.

4.6.6 Parallel Connection

The MultiPlus can be connected in parallel with several identical devices. To this end, a connection is established between the devices by means of standard RJ45 UTP cables. The system (one or more Multi’s plus optional control panel) will require subsequent configuration (see Section 5). In the event of connecting MultiPlus units in parallel, the following requirements must be met:

• A maximum of six units connected in parallel.

• Only identical devices with the same power ratings may be connected in parallel.

• Battery capacity should be sufficient.

• The DC connection cables to the devices must be of equal length and cross-section.

• If a positive and a negative DC distribution point is used, the cross-section of the connection

between the batteries and the DC distribution point must at least equal the sum of the required cross-sections of the connections between the distribution point and the MultiPlus units.

• Place the MultiPlus units close to each other, but allow at least 10 cm for ventilation purposes under, above and beside the units.

• UTP cables must be connected directly from one unit to the other (and to the remote panel). Connection/splitter boxes are not permitted.

• A battery-temperature sensor need only be connected to one unit in the system. If the temperature of several batteries is to be measured, you can also connect the sensors of other MultiPlus units in the system (with a maximum of one sensor per MultiPlus).

EN NL FR DE ES Appendix

Temperature compensation during battery charging responds to the sensor indicating the highest temperature.

• Voltage sensing must be connected to the master (see Section 5.5.1.4).

• If more than three units are connected in parallel in one system, a dongle is required (see

Section 5).

• Only one remote control means (panel or switch) can be connected to the system.

4.6.7 Three-phase operation

The MultiPlus can also be used in 3-phase configuration. To this end, a connection between the devices is made by means of standard RJ45 UTP cables (the same as for parallel operation). The system (Multi’s plus an optional control panel) will require subsequently configuration (see Section 5). Pre-requisites: see Section 4.6.6.

5. Configuration

•

Settings may only be changed by a qualified electrical engineer.

• Read the instructions thoroughly before implementing changes.

• During setting of the charger, the AC input must be removed.

5.1 Standard settings: ready for use

5.2 Explanation of settings

Settings that are not self-explanatory are described briefly below. For further information, please refer to the help files in the software configuration programs (see Section 5.3).

Inverter frequency Output frequency if no AC is present at the input. Adjustability: 50Hz; 60Hz

Input frequency range

Input frequency range accepted by the MultiPlus. The MultiPlus synchronises within this range with the AC input frequency. The output frequency is then equal to the input frequency. Adjustability: 45 – 65 Hz; 45 – 55 Hz; 55 – 65 Hz

Input voltage range Voltage range accepted by the MultiPlus. The MultiPlus synchronises within this range with the AC input voltage. The output voltage is then equal to the input voltage. Adjustability: Lower limit: 180 - 230V Upper limit: 230 - 270V

Inverter voltage Output voltage of the MultiPlus in battery operation. Adjustability: 210 – 245V

Stand-alone / parallel operation / 2-3 phase setting

Using several devices, it is possible to:

• increase total inverter power (several devices in parallel)

• create a split-phase system (only for MultiPlus units with 120V output

voltage)

• create a 3-phase system.

To this end, the devices must be mutually connected with RJ45 UTP cables. Standard device settings, however, are such that each device operates in stand-alone operation. Reconfiguration of the devices is therefore required.

AES (Automatic Economy Switch) If this setting is turned ‘on’, the power consumption in no-load operation and with low loads is decreased by approx. 20%, by slightly 'narrowing' the sinusoidal voltage. Not adjustable with DIP switches. Applicable in stand-alone configuration only.

Ground relay (see appendix B)

With this relay (H), the neutral conductor of the AC output is grounded to the chassis when the back feed safety relay is open. This ensures the correct operation of earth leakage circuit breakers in the output. If a non-grounded output is required during inverter operation, this function must be turned off. (See also Section 4.5) Not adjustable with DIP switches.

Charging characteristics The standard setting is ‘Four-stage adaptive with BatterySafe mode’. See Section 2 for a description. This is the best charging characteristic. See the help files in the software configuration programs for other features. ‘Fixed’ mode can be selected with DIP switches.

Battery type The standard setting is the most suitable for Victron Gel Deep Discharge, Gel Exide A200, and tubular plate stationary batteries (OPzS). This setting can also be used for many other batteries: e.g. Victron AGM Deep Discharge and other AGM batteries, and many types of flat-plate open batteries. Four charging voltages can be set with DIP switches.

Absorption time

This depends on the bulk time (adaptive charging characteristic), so that the battery is optimally charged. If the ‘fixed’ charging characteristic is selected, the absorption time is fixed. For most batteries, a maximum absorption time of eight hours is suitable. If an extra high absorption voltage is selected for rapid charging (only possible for open, flooded batteries!), four hours is preferable. With DIP switches, a time of eight or four hours can be set. For the adaptive charging characteristic, this determines the maximum absorption time.

Storage voltage, Repeated Absorption Time, Absorption Repeat Interval

See Section 2. Not adjustable with DIP switches.

Bulk Protection When this setting is ‘on’, the bulk charging time is limited to 10 hours. A longer charging time could indicate a system error (e.g. a battery cell short-circuit). Not adjustable with DIP switches.

AC input current limit

These are the standard current limit settings for which PowerControl and PowerAssist come into operation. The standard setting is 30A. In case of models with max. 16A feed through current, the maximum is automatically reduced to 16A. See Section 2, the book 'Energy Unlimited', or the many descriptions of this unique feature on our website www.victronenergy.com .

EN NL FR DE ES Appendix

UPS feature

If this setting is ‘on’ and AC on the input fails, the MultiPlus switches to inverter operation practically without interruption. The MultiPlus can then be used as an Uninterruptible Power Supply (UPS) for sensitive equipment such as computers or communication systems. The output voltage of some small generator sets is too unstable and distorted for using this setting – the MultiPlus would continually switch to inverter operation. For this reason, the setting can be turned off. The MultiPlus will then respond less quickly to AC input voltage deviations. The switchover time to inverter operation is consequently slightly longer, but most equipment (computers, clocks or household equipment) is not adversely impacted. Recommendation: Turn the UPS feature off if the MultiPlus fails to synchronise, or continually switches back to inverter operation.

Dynamic current limiter

Intended for generators, the AC voltage being generated by means of a static inverter (so-called ‘inverter’ generators). In these generators, rpm is down-controlled if the load is low: this reduces noise, fuel consumption and pollution. A disadvantage is that the output voltage will drop severely or even completely fail in the event of a sudden load increase. More load can only be supplied after the engine is up to speed. If this setting is ‘on’, the MultiPlus will start supplying extra power at a low generator output level and gradually allow the generator to supply more, until the set current limit is reached. This allows the generator engine to get up to speed. This setting is also often used for ‘classical’ generators that respond slowly to sudden load variation.

WeakAC

Strong distortion of the input voltage can result in the charger hardly operating or not operating at all. If WeakAC is set, the charger will also accept a strongly distorted voltage, at the cost of greater distortion of the input current. Recommendation: Turn WeakAC on if the charger is hardly charging or not charging at all (which is quite rare!). Also turn on the dynamic current limiter simultaneously, and reduce the maximum charging current to prevent overloading the generator if necessary. Not adjustable with DIP switches.

BoostFactor

Change this setting only after consulting with Victron Energy or with an engineer trained by Victron Energy! Not adjustable with DIP switches.

Multi-functional relay

By default, the multi-functional relay is set as an alarm relay, i.e. the relay will deenergise in the event of an alarm or a pre-alarm (inverter almost too hot, ripple on the input almost too high, battery voltage almost too low). Not adjustable with DIP switches.

VirtualSwitch

The VirtualSwitch is a software function in the MultiPlus microprocessor. The inputs of this function are parameters that can be selected with VEConfigure (e.g. certain alarms or voltage levels). The output is binary (0 or 1). The output can be connected to a binary microprocessor output (e.g. the multi-functional relay, or the relay in one of the AC inputs).

If connected to the multi-functional relay, and with battery voltage and time as input values, for example, the VirtualSwitch can be configured to supply a generator starting signal.

If connected to an AC input relay, and with battery voltage and time as input, for example, the connected mains supply can be interrupted.

5.3 Configuration by computer

All settings can be changed by means of a computer or with a VE.Net panel (except for the multi-functional relay and the VirtualSwitch when using VE.Net). The most common settings (including parallel and 3-phase operation) can be changed by means of DIP switches (see Section 5.5).

For changing settings with the computer, the following is required:

- VEConfigureII software. You can download the VEConfigureII software free of charge at www.victronenergy.com .

- A RJ45 UTP cable and the MK2.2b RS485-to-RS232 interface. If your computer has no RS232 connection, but does have USB, you will also need a RS232-to-USB interface cable. Both are available from Victron Energy.

5.3.1 VE.Bus Quick Configure Setup VE.Bus Quick Configure Setup is a software program with which systems with a

maximum of three Multi’s (parallel or three phase operation) can be configured in a simple manner. VEConfigureII forms part of this program. You can download the software free of charge at www.victronenergy.com . For connection to your computer, a RJ45 UTP cable and the MK2.2b RS485-to- RS232 interface is required. If your computer does not have a RS232 connection but is equipped with USB, you will also need a RS232-to-USB interface cable. Both are available from Victron Energy.

5.3.2 VE.Bus System Configurator and dongle

For configuring advanced applications and/or systems with four or more Multi’s, VE.Bus System Configurator software must be used. You can download the software at www.victronenergy.com . VEConfigureII forms part of this program. You can configure the system without a dongle, and use it for 15 minutes (as a demonstration facility). For permanent use, a dongle – available at additional charge – is required. For connection to your computer, a RJ45 UTP cable and the MK2.2b RS485-to- RS232 interface is required. If your computer does not have a RS232 connection but is equipped with USB, you will also need a RS232-to-USB interface cable. Both are available from Victron Energy.

5.4 Implementing settings with a VE.Net panel

To this end, a VE.Net panel and the VE.Net to VE.Bus converter is required. With VE.Net you can set all parameters, with the exception of the multi-functional relay and the VirtualSwitch.

5.5 Configuration with DIP switches

A number of settings can be changed using DIP switches (see appendix A, position M).

This is done as follows:

Turn the Multi on, preferably unloaded en without AC voltage on the inputs. The Multi will then operate in inverter mode.

Step 1: Setting the DIP switches for:

- the required current limitation of the AC input.

- AES (Automatic Economy Switch)

- limitation of the charging current.

- selection of stand-alone, parallel or 3-phase operation.

To store the settings after the required values have been set: press the 'Up' button for 2 seconds (upper button to the right of the DIP switches, see appendix A, position K). You can now re-use the DIP switches to apply the remaining settings (step 2).

Step 2: other settings To store the settings after the required values have been set: press the 'Down' button for 2 seconds (lower button to the right of the DIP switches). You can now leave the DIP switches in the selected positions, so that the ’other settings’ can always be recovered.

Remarks:

- The DIP switch functions are described in 'top to bottom' order. Since the uppermost DIP switch has the highest number (8), descriptions start with the switch numbered 8.

- In parallel mode or 3-phase mode, not all devices require all settings to be made (see section 5.5.1.4). For parallel or 3-phase mode, read the whole setting procedure and make a note of the required DIP switch settings before actually implementing them.

5.5.1 Step 1

5.5.1.1 Current limitation AC input (default: 16A for models with max. 16A feed through current, and 30A for models with max. 30A feed through current)

If the current demand (Multi load + battery charger) threatens to exceed the set current, the Multi will first reduce its charging current (PowerControl), and subsequently supply additional power from the battery (PowerAssist), if needed.

The AC input current limit can be set to eight different values by means of DIP switches. With a Phoenix Multi Control Panel, a variable current limit can be set for the AC input.

Remark: With a Duo Control Panel and an external AC change-over switch two different limits can be set, for two AC sources, for example a shore connection and a generator.

EN NL FR DE ES Appendix

Procedure

The AC input current limit can be set using DIP switches ds8, ds7 and ds6 (default setting: 30A, automatically limited to 16A in 16A models). Procedure: set the DIP switches to the required value: ds8 ds7 ds6

off off off = 4A (0,9kVA at 230V) off off on = 6A (1,4kVA at 230V) off on off = 10A (2.3kVA at 230V) off on on = 12A (2.8kVA at 230V) on off off = 16A (3.7kVA at 230V) on off on = 20A (4.6kVA at 230V) on on off = 25A (5,7kVA at 230V) on on on = 30A (6.9kVA at 230V)

Remark: Manufacturer-specified continuous power ratings for small

generators are sometimes inclined to be rather optimistic. In that case, the current limit should be set to a much lower value than would otherwise be required on the basis of manufacturer-specified data.

5.5.1.2 AES (Automatic Economy Switch)

Procedure: set ds5 to the required value:

ds5

off = AES off on = AES on

5.5.1.3 Charging current limitation (default setting 75%)

For maximum battery life, a charging current of 10% to 20% of the capacity in Ah should be applied. Example: optimal charging current of a 24V/500Ah battery bank: 50A to 100A. The temperature sensor supplied automatically adjusts the charging voltage to the battery temperature. If faster charging – and a subsequent higher current – is required:

- The temperature sensor supplied should always be fitted, since fast charging can lead to a considerable temperature rise of the battery bank. The charging voltage will be adapted to the higher temperature (i.e. lowered) by means of the temperature sensor.

- The bulk charging time will sometimes be so short that a fixed absorption time would be more satisfactory (‘fixed’ absorption time, see ds5, step 2).

Procedure

The battery charging current can be set in four steps, using DIP switches ds4 and ds3 (default setting: 75%).

ds4 ds3

off off = 25% off on = 50% on off = 75% on on = 100%
