Introduction

Models

Sealed Mobile Models

Sealed inverter models are designed for dusty and humid environments and can survive casual exposure to the elements. However, enclosed protection is still recommended. These inverters are internally ventilated and do not use outside air for cooling. To compensate, most sealed models are also equipped with the OutBack Turbo Fan assembly which uses external air to remove heat from the chassis.



FX2536MT (2.5 kVA output, 36 Vdc)



FX3048MT (3.0 kVA output, 48 Vdc)

Vented Mobile Models

Vented inverter models are intended for indoor or protected installation only. On average, the wattage of vented models is rated higher than sealed models. This is due to the greater cooling capabilities of the vented models.



VFX3648M (3.6 kVA output, 48 Vdc)

Inverter Model Names

FX mobile model numbers use the following naming conventions.



The model number includes “FX” as the inverter series.



Vented models are preceded with “V”, as in “VFX3648M”.



The first two digits show the power of that model. For example, “FX2012MT” is 2000 watts.



The second pair of digits shows the inverter’s nominal DC voltage. For example, “FXR2524MT” is 24 volts.



Models equipped with a Turbo Fan end with the letter “T”. This designation indicates a sealed model. Vented FX inverter models are not equipped with Turbo Fans. (Model FX2024M is a sealed model without a Turbo Fan.)



Mobile models (all models featured in this manual) use the letter “M” as either the last or second to last character (as in “FX2012MT” or “VFX2012M”). These models are meant to be installed in a vehicle and should not be installed anywhere else. Similarly, a non-mobile inverter should not normally be installed in a vehicle. For this reason this manual refers to “M” series inverters as “mobile”. installed accordingly.

IMPORTANT:

Installing an inverter in the wrong application invalidates its listing, may violate installation codes, and may void the inverter’s warranty.

Other inverters, if they are referenced, are referred to as “permanently installed.”

Applications

OutBack inverter/chargers are designed to use a battery bank to store energy. In shore-based mobile and marine connections, the shore power is used as the primary source. When the shore power is removed, the inverter takes over to run the loads from the batteries. The settings can be changed to accommodate many applications. Changes are made with the system display.

Mobile FX inverter/chargers work together with power from the utility grid (shore power), generator, vehicle alternator, and/or renewable energy sources such as photovoltaic (PV) modules. When not using the batteries, the inverter can charge it from an AC source. The alternator, PV harvest, or other DC sources can also be used to recharge the batteries.

The FX inverter has one set of terminals for a single AC source. However, it can use two AC sources when an external transfer switch is installed. The inverter can be independently programmed for each source. It is common to use shore power and an AC generator. Other combinations of AC sources are possible.

Renewable Energy

The inverter cannot connect directly to PV, alternators, or other DC sources. The batteries are the inverter’s primary source of power. However, if the DC sources are used to charge the batteries, the inverter can use their energy by drawing it from the batteries.

A renewable source is always treated as a battery charger, even if all of its power is used immediately. The renewable source must have a charge controller, or some other regulation method, to prevent overcharging. OutBack Power’s FLEXmax family of charge controllers can be used for this purpose, as can other products.

Battery Bank

When planning a battery bank, consider the following:



Cables

determine the placement of the battery bank. Local codes or regulations may apply and will take priority over OutBack recommendations.



Battery Type

~ The cycle was designed for lead-chemistry batteries intended for deep discharge. These include batteries for RV, marine,

IMPORTANT:

Battery charger settings need to be correct for a given battery type. Always follow battery manufacturer recommendations. Making incorrect settings, or leaving them at factory default settings, may cause the batteries to be undercharged or overcharged.

CAUTION: Hazard to Equipment

Batteries can emit vapors which are corrosive over long periods of time. Installing the inverter in the battery compartment may cause corrosion which is not covered by the product warranty. (Sealed batteries may be an exception.)



Bank Size:

Battery bank capacity is measured in amp-hours. Determine the required bank specifications as

accurately as possible, beginning with the items below. This avoids underperformance or wasted capacity. These ten items are obtainable in different places, summarized in Table 2 on the next page. Some of the

information is specific to the site or application. Some can be obtained from the battery manufacturer. Information on OutBack products is available from OutBack Power Technologies or its dealers.

A. Size of load: B. Daily hours of use: C. Days of autonomy:

D. Application: This often helps define or prioritize the previous three items. Off-grid systems often require enough

capacity to last for an extended period before recharging. Grid-connected systems frequently need only enough capacity for short-term backup during outages.

These are the most basic and essential factors used to determine bank size.

900-0197-01-00 Rev A

Page 11

Planning

E. Conductor efficiency: Wire size and other factors will waste

power due to resistance and voltage drop. Typical acceptable efficiency is 96 to 99%.

F. Inverter efficiency: FX specifications list “Typical Efficiency”

to help estimate operating loss.

G. System DC voltage: Each inverter model requires a specific DC voltage to operate. H. Battery voltage: Most individual battery voltages are less than the system DC voltage. The batteries may need to be

placed in series to deliver the correct voltage.

I. Capacity: Battery capacity, which is measured in

amp-hours, is not usually a fixed number. It is specified based on the rate of discharge. For example, the OutBack EnergyCell 200RE is rated at 134.5 Ahr when discharged at the 5-hour rate (to terminal voltage 1.85 Vpc). This is a high rate of discharge that would hypothetically drain the battery in 5 hours. The same battery is rated at 191 Ahr when used at the 100-hour rate. Use the appropriate discharge rate (correlated to the expected loads) to measure the capacity of a battery. Use battery specifications for terminal voltage 1.85 Vpc whenever possible.

NOTE: Capacity ratings are for batteries at 25°C. Capacity is reduced at cooler temperatures.

J. Maximum depth of discharge (DoD): Most batteries cannot be discharged below a certain level without damage. The

bank requires enough total capacity to keep this from happening.

To Calculate Minimum Battery Bank Size (refer to Table 2 for letter designations):

Any losses are essentially amp-hour capacity that the system cannot use. The battery bank size can be increased to account for losses.

The load size, item A, is measured in watts. Compensate this figure for efficiency loss. Multiply the conductor efficiency by the inverter efficiency (E x F). (These items are represented as percentages, but may be displayed as decimals for calculation.) Divide item A by the result.

2. Convert the compensated load into amperes (Adc). Divide the step 1 result by the system voltage (item G).

3. Determine the daily load consumption in ampere-hours (amp-hours, or Ahr). Multiply the step 2 result by

the daily usage hours (item B).

4. Adjust the total for required days of autonomy (the days the system must operate without recharging)

and the maximum DoD. Multiply the step 3 result by C and divide by J.

The result is the total amp-hour capacity required for the battery bank.

5. Determine the number of parallel battery strings required. Divide the Ahr figure from step 4 by the

individual battery capacity (I). Round the result to the next highest whole number.

6. Determine the total number of batteries required. Divide the system voltage by the battery voltage

(G ÷ H). Multiply the result by the step 5 result.

The result is the total required quantity of the chosen battery model.

The FX inverter can accept single-phase input from a generator that delivers clean AC power in the range of voltage and frequency specified for that model.

~ Inverters stacked for split-phase output (120/240 Vac) can work with both output lines of a split-phase generator.

See pages 30, 32, and 36.

~ Inverters stacked for three-phase output can work with three-phase generators. See page 38.

The inverter/charger can provide a start signal to control an automatic start generator. If automatic generator starting is required, the generator must be an electric-start model with automatic choke. It should have two-wire start capability. For other configurations, additional equipment may be required.

6) [G ÷ H] x 5 [48 ÷ 12] x 1 strings = 4 batteries



In any configuration, the inverter may need to be specifically programmed using the system display. Perform all programming according to the specifications of the generator and the required operation of the inverter. Parameters to be programmed may include generator size, automatic starting requirements, and potential fluctuations in generator AC voltage.

Mobile generators are usually equipped with a bond between the neutral and ground connections. Mobile FX inverter models have neutral-ground switching. This function establishes a bond on the inverter when no generator is present, but removes it when the generator is running. See page 15 for more information on neutral-ground bonding.

Generator Sizing

A generator should be sized to provide enough power for all the loads and the battery charger. The generator size should assume maximum loads and maximum charging at the same time.



Available generator power may be limited by ratings for circuit breakers and/or generator connectors.



The generator must be able to provide current to all inverters on a given phase or output. Minimum generator

is usually recommended to be twice the power of the inverter system. For example, a 2 kVA inverter should

size have a 4 kVA (or larger) generator. Many generators may not be able to maintain AC voltage or frequency for long periods of time if they are loaded more than 80% of rated capacity.



In addition, if a split-phase 120/240 Vac generator is powering a single-phase 120 Vac inverter system with no other compensation, it is

required

heavily loaded on one output line may suffer severely from balancing issues. The OutBack FW-X240 or PSX-240 balancing transformers may compensate for this condition.

IMPORTANT:

In general, the generator output should match the stacking and output of the inverters. A three-phase generator should not be used with a 120/240 Vac inverter system.

This is the generator size after derating for environment, use, and other factors.

A purely 240 Vac generator will cause damage if used with a 120 Vac inverter system.

Installation

Location and Environmental Requirements

Sealed (FX) models are resistant to water and other elements but are not designed for permanent outdoor installations. If installation on the outside of a vehicle is required, the FX inverter must be installed under cover and protected from direct exposure to the environment. Vented (VFX) models are not resistant to water and other elements. They must be installed in a weather-proof enclosure or enclosed area.



The inverter can often be mounted in any position or orientation. If there is any exposure to moisture or condensation, the inverter must not be mounted upside-down. This ensures that water will not accumulate under the DC cover. However, it can still be mounted in other positions or orientations.



For installations where the inverter may be exposed to moisture or condensation, a sealed model must be used and mounted either with the base down (shelf mounting) or with the AC wiring compartment facing down (wall mounting). If mounted with the base down, water cannot be allowed to accumulate around the inverter’s base. There is a drainage system on the base of the inverter to dispel condensation. If submerged, water can enter this drain and cause failure.



Vented inverters must be installed in a weather-proof enclosure or enclosed area. These models are not designed for exposure to water or excessive wind-blown dust and debris.



When inverters are installed with an OutBack FLEXpower system, the system must be installed in the upright orientation due to the requirements of the circuit breakers.



Any inverter will perform more efficiently in locations offering plenty of air circulation. The recommended minimum clearance is 2 inches (5 cm) on all sides of the inverter.



Any inverter will function to all of its specifications if operated in a range of –4°F to 122°F (–20°C to 50°C).



The inverter will function, but will not necessarily meet its specifications, if operated in a temperature range of –0°F to 140°F (–40°C to 60°C). This is also the allowable temperature range for storage.



The FX series of inverters carry an Ingress Protection (IP) rating of 20 and a Relative Humidity (RH) rating of 93% (non-condensing).



Inverter specifications are listed in the FX Mobile Series Inverter/Charger Operator’s Manual.

Installation

Mounting



One person can install the FX inverter, but installation may be easier with two people.



The unit has four mounting holes, one in each corner. Use fasteners in all corners for a secure installation.



Due to the variance in other mounting methods, OutBack only endorses the use of FLEXware mounting products or previous versions of OutBack mounting plates. Use M6 x 20 mm machine screws, one per corner, to attach the inverter to the mounting plate. Follow the instructions with each mounting system.



Mount and secure each component before attaching any wiring.



When the inverter is used with other metal chassis, make sure that all chassis are grounded appropriately. (See the grounding instructions on page 15.) Grounding other chassis may involve metal-to-metal contact, or separate ground wires.

If using an OutBack FLEXware Mounting Plate, avoid large air gaps behind the plate. These can result in louder mechanical noise during heavy inverting or charging. Mount the plate on a flat, solid mounting surface.

IMPORTANT:

Use correct fasteners to secure the inverter to the mounting surface, regardless of the type of surface. OutBack cannot be responsible for damage to the product if it is attached with inadequate fasteners.

Grounding

Table 3 Ground Conductor Size and Torque Requirements

WARNING: Shock Hazard



Mobile models perform automatic neutral-to-ground bond switching. When this function is engaged, the chassis ground is electrically common with the output neutral conductor. When disengaged, the chassis ground is isolated from the AC system. See pages 17, 21, and 22.



Make sure that no more than one bond is present in the AC system at any time.

WARNING: Shock Hazard

For all installations, the negative battery conductor should be bonded to the grounding system at only one point. If the OutBack GFDI is present, it can provide the bond.

IMPORTANT:

Not all OutBack products can be used in a positive-ground system. If it is necessary to build a positive-ground system with OutBack products, contact OutBack Technical Support at +1.360.618.4363 before proceeding.

The control logic for the AUX output is not always located in the same device. Inverter AUX functions are located within the inverter itself and are described accordingly. Although inverter-based functions require the system display for programming, they will function even if the display is removed. However, AGS programming is located within the system display and will not work if the display is removed. Other devices may also be able to control the terminals.

The generator must be an electric-start model with automatic choke. It is recommended to have “two-wire” start capability. A two-wire-start generator is the simplest type, where the cranking and starting routine is automated. It usually has a single switch with two positions that is turned ON to start, OFF to stop.

Multiple-Inverter AC Installations (Stacking)

Installing multiple inverters in a single AC system allows larger loads than a single inverter can handle. This requires stacking. Stacking inverters refers to how they are wired within the system and then programmed to coordinate activity. Stacking allows all units to work together as a single system.

Examples of stacking configurations include “classic series”, “OutBack series”, “parallel”, “series/parallel”, and “three-phase” configurations.

Stacking Connections

Stacking requires an OutBack communications manager and a system display.



If the MATE or MATE2 System Display is used, it must have firmware revision 4.1.6 or above.



A system of four or fewer units may use the HUB4 Communications Manager.



A system of up to ten units requires the HUB10.3 Communications Manager.

All interconnections between the products are made using CAT5 straight-through (non-crossover) cable.

Each inverter must be assigned a stacking mode depending on the configuration. Modes are described below. Mode names sometimes vary with inverter model; see Table 5 on page 29.



The master provides the primary output phase. Other inverters in the system base their phase on that of the master. If the master shuts off, all other inverters also shut off. The master must sense and connect to an AC source before other inverters can connect.

~ In all cases, the master inverter must be connected to port 1 on the communications manager. ~ In a parallel-stacked or OutBack-stacked system, the master tends to be the most heavily used unit. ~ The selection for three-phase master is different from the single-phase master.

28 900-0197-01-00 Rev A

Page 29

Installation

There are two types of slave modes. The names used here are derived from their references onscreen.



A “classic” slave is used for stacking when the slave operates semi-independently of the master. Although the master sets the phase relationship, the slave creates an output independent of the master. It is not possible to balance the outputs with the FW-X240 transformer using this method. This type of system is used for the most basic form of series stacking (two inverters only) and for three-phase stacking.

~ Classic-stacked inverters can go into Search mode independently of the master if necessary.



An “OutBack” slave is used for parallel or series/parallel systems. In parallel stacking, all slaves are in phase with the master. In series/parallel systems, some slaves are in phase with the master and some are 180° out of phase. The FW-X240 autoformer can balance the loads of OutBack-stacked inverters.

~ All slave outputs are pulse-width-matched to be precisely synchronized with the master inverter. This avoids potential

backfeed situations.

~ OutBack slaves can be placed in Power Save mode when not in use. They are activated by the master inverter as

needed. For this reason, the master is normally the only inverter to enter Search mode. See the Operator’s Manual for descriptions of Power Save and Search mode.

In many cases the port assignments for secondary inverters (ports 2 to 4 or 2 to 10) is important. In general it is always important to keep track of units and ports for programming purposes. See the communications manager and system display literature for more information.

Programming involves using the system display to assign a status and stacking value to the inverter on each port. Each inverter is assigned to power a specified phase of the system. These assignments can be changed at any time as long as the master is plugged into port 1.

IMPORTANT:

The master inverter must always be connected to port 1 on the communications manager. Connecting it elsewhere, or connecting a slave to port 1, will result in backfeed or output voltage errors which will shut the system down immediately.

Installing multiple inverters without stacking them (or stacking them incorrectly) will result in similar errors and shutdown.

Although stacking allows greater capacity, the loads, wiring, and overcurrent devices must still be sized appropriately. Overloading may cause circuit breakers to open or the inverters to shut down.

Stacking Configurations

Classic Series Stacking (Dual-Stack)

In series stacking, two inverters create two separate 120 Vac output phases. One inverter is the master. The other is a slave that is intentionally 180° out of phase with the master. Each of these outputs can be used to power a separate set of 120 Vac loads. Collectively they form a “split-phase” configuration which produces 240 Vac. “Classic” series stacking is the simplest way to achieve this output.



The two outputs operate independently of each other. The 120 Vac loads on each output cannot exceed a given inverter’s size. The second inverter cannot assist.



Only two inverters, one per output, may be classic series stacked. They must be the same model.

OutBack Series Stacking (Dual-Stack)

In OutBack’s unique series stacking, two inverters create a “split-phase” configuration. This configuration creates two separate 120 Vac output legs. One output is the master. The other is a slave that is intentionally 180° out of phase with the master. The collective voltage is 240 Vac, as in Classic stacking. However, the output loads are balanced with the FW-X240 autotransformer.



The slave output is controlled directly by the master and cannot operate independently.



In the event of a load imbalance in a 120/240 Vac system, the FW-X240 transformer can transfer power from one output to the other. The transfer balances the loads on each inverter. It also allows heavy 120 Vac loads on either leg to use the full power of both inverters. (The loads below are marked “2+ kVA” per output. This means the power of a 2 kVA inverter is assisted by the other output.)



The slave can go into Power Save mode when not in use. The FW-X240 autotransformer allows the master to power loads on either output. This reduces idle power consumption and improves system efficiency.



Additional inverters can be added for combination series/parallel operation. See page 36. All inverters must be the same model.

Parallel Stacking (Dual-Stack and Larger)

In parallel stacking, two or more inverters create a single, common 120 Vac bus.



All inverters share a common input (AC source). The inverters run loads on a common output bus. The master inverter provides the primary output. The slaves are connected to the same output and assist the master.



The slave outputs are controlled directly by the master and cannot operate independently.



Slave inverters can go into Power Save mode when not in use. The master will activate individual slaves based on load demand. This reduces idle power consumption and improves system efficiency.



Up to ten inverters may be installed in a parallel arrangement. The example on this page shows three inverters. The wiring diagram on the next page shows four. All inverters must be the same model.

Three-Phase Stacking

In three-phase stacking, inverters create three separate 120 Vac output phases in a wye configuration.



The output of each inverter is 120° out of phase from the others. Any two outputs produce 208 Vac between them. The outputs can be used to power three-phase loads when all inverters work together.



The 120 Vac loads on each output cannot exceed a given inverter’s wattage. The other outputs cannot assist.



Only three inverters, one per phase, may be installed in a three-phase arrangement. All inverters must be the same model.

Functional Test

WARNING: Shock Hazard and Equipment Damage

The inverter’s AC and DC covers must be removed to perform these tests. The components are close together and carry hazardous voltages. Use appropriate care to avoid the risk of electric shock or equipment damage.

It is highly recommended that all applicable steps be performed in the following order. However, if steps are inapplicable, they can be omitted.

If the results of any step do not match the description, see the Operator’s Manual for troubleshooting.

Pre-startup Procedures

1. Ensure all DC and AC overcurrent devices are opened, disconnected, or turned off.

2. Double-check all wiring connections.

3. Confirm that the total load does not exceed the inverter’s rated power.

4. Inspect the work area to ensure tools or debris have not been left inside.

5. Using a digital voltmeter (DVM) or standard voltmeter, verify battery voltage. Confirm the voltage

is correct for the inverter model. Confirm the polarity.

6. Connect the system display, if present.

CAUTION: Equipment Damage

Incorrect battery polarity will damage the inverter. Excessive battery voltage also may damage the inverter. This damage is not covered by the warranty.

WARNING: Shock Hazard

The inverter’s AC output is defaulted to ON from the factory. It will deliver 120 Vac as soon as DC power is connected.

Startup

To start a single-inverter system:

1. Close the main DC circuit breakers (or connect the fuses) from the battery bank to the inverter.

The inverter will activate. Do not turn on any AC circuit breakers at this time. Confirm that the system display is operational, if present.

2. Observe the LED indicators in the AC wiring compartment. One of the three BATTERY indicators

should be illuminated (green, yellow, or red). Any of them are acceptable at this stage. INVERTER (green) should come on at this time. The fan will run briefly and the relay will click as a self-test.

3. If a system display is present, perform all programming for all functions. These functions may

900-0197-01-00 Rev A

include input current limits, battery charging, generator starting, and others.

Page 42

Installation

Figure 32 AC Terminals

4. Using a DVM or voltmeter, measure between the AC HOT OUT and AC NEUTRAL OUT terminals.

(See Figure 32.) The inverter is working correctly if the AC output reads within 10% of 120 Vac.

Proceed past the items below to Step 5.

To start a multiple-inverter (stacked) system:

1. Close the main DC circuit breakers (or connect the fuses) from the battery bank to the master

inverter. The inverter will activate. Do not turn on any AC circuit breakers at this time. Confirm that the system display is operational.

2. Observe the LED indicators in the AC wiring compartment. One of the three BATTERY indicators

Repeat steps 1 and 2 for every inverter present.

3. With the system display, perform programming for stacking and all other functions. These

functions may include input current limits, battery charging, and generator starting. All parallelstacked slave inverters will observe the master programming settings and do not need to be programmed individually. The MATE3 Configuration Wizard may be used to assist programming.

4. Using the system display, temporarily bring each slave out of Silent mode by raising the Power

Save Level of the master.

 As each slave is activated, it will click and create an audible hum.  Confirm that the system display shows no fault messages.

Using a DVM or voltmeter, measure between the AC HOT OUT terminal on the master inverter and AC HOT OUT on each slave. Series inverters should read within 10% of 120 Vac. Parallel inverters should read close to zero. Three-phase inverters should read within 10% of 208 Vac.

 When this test is finished, return the master to its previous Power Save Level.

After output testing is completed, perform the following steps:

5. Close the AC output circuit breakers. If AC bypass switches are present, place them in the normal

(non-bypass) position. Do not connect an AC input source or close any AC input circuits.

6. Use a DVM to verify correct voltage at the AC load panel.

7. Connect a small AC load and test for proper functionality.

42 900-0197-01-00 Rev A

Page 43

8. Close the AC input circuit breakers and connect an AC source.

 Using a DVM or voltmeter, check the AC HOT IN and AC NEUTRAL IN terminals for 120 Vac

from the AC source.

 If a system display is present, confirm that the inverter accepts the AC source as appropriate for its

programming. (Some modes or functions may restrict connection with the source. If one of these selections has been used for the system, it may not connect.) Check the system display indicators for correct performance.

9. If the charger is activated, the inverter will perform a battery charging cycle after powering up.

This can take several hours. If restarted after a temporary shutdown, the inverter may skip most or all of the charging cycle. Confirm that it is charging as appropriate by using the system display.

10. Test other functions which have been enabled, such as generator start or search mode.

11. Compare the DVM’s readings with the system display meter readings. If necessary, the system

display’s readings can be calibrated to match the DVM more accurately. Calibrated settings include AC input voltage, AC output voltage, and battery voltage.

Powering Down

These steps will completely isolate the inverter.

To remove power from the system:

1. Turn off all load circuits and AC input sources.

Installation

2. Turn off all renewable energy circuits.

3. Turn each inverter OFF using the system display or external switch.

4. Turn off the main DC overcurrent devices for each inverter.

Adding New Devices

When adding new devices to the system, first turn off the system according to the Power Down instructions. After adding new devices, perform another functional test, including programming.
