Introduction Audience This manual provides instructions for setup and operation of the product. It does not cover installation. The manual is intended to be used by anyone required to operate the FXR Series Inverter/Charger. Operators must be familiar with all the safety regulations pertaining to operating power equipment of this type as required by local code. Operators are advised to have basic electrical knowledge and a complete understanding of this equipment’s features and functions.
Introduction Welcome to OutBack Power Technologies Thank you for purchasing the OutBack FXR Series Inverter/Charger. It is designed to offer a complete power conversion system between batteries and AC power. As part of an OutBack Grid/Hybrid™ system, it can provide off-grid power, grid backup power, or grid-interactive service which sells excess renewable energy back to the utility.
Introduction Uses the MATE3™ System Display and Controller or the AXS Port™ SunSpec Modbus Interface (sold separately) for user interface as part of a Grid/Hybrid system MATE3 must have firmware revision 003.007.xxx or higher Supports the OPTICS RE™ online tool1 for a cloud-based remote monitoring and control application Requires the MATE3 or the AXS Port Visit www.outbackpower.com to download Uses the HUB10.
Introduction The MATE3’s Configuration Wizard is capable of automatically configuring inverters to a series of preset values. This is often more efficient than attempting to manually program each setting in each inverter. Affected fields include system type, battery charging, and AC source configuration. IMPORTANT: The MATE3 system display must have firmware revision 003.007.xxx or higher. IMPORTANT: Some functions are not based in the inverter, but are part of the MATE3 firmware.
Operation LED Indicators AUX Indicator (see page 46) Battery Indicators Status Indicators Figure 3 LED Indicators Battery Indicators The Battery LED indicators show the approximate battery state. (See IMPORTANT note below.) The Battery indicators and the Inverter Status indicators are independent. They may accompany each other depending on conditions. Common combinations are noted on page 12. A green indicator (FULL) means the batteries have an adequate charge at that time.
Operation Status Indicators STATUS INVERTER (Green): Solid: The FXR inverter is on and providing power. If accompanied by a solid yellow AC IN indicator (2), the inverter is also connected to the utility grid with an AC input mode that uses both inverter power and grid power (Support, Grid Tied, or GridZero). See page 13 for descriptions of AC input modes. Flashing: The inverter has been turned on but is idle. The inverter is likely in Search mode. See page 24. Off: The inverter is off.
Operation Inverter Functionality The FXR inverter can be used for many applications. Some of the inverter’s operations occur automatically. Others are conditional or must be enabled manually before they will operate. Most of the inverter’s individual operations and functions can be programmed using the system display. This allows customization or fine tuning of the inverter’s performance. Before operating the inverter: The operator needs to define the application and decide which functions will be needed.
Operation When multiple inverters are stacked together in parallel, the master inverter’s input mode is imposed on all slaves. (See the stacking section on page 39.) The slave settings are not changed; they retain any mode that was previously programmed. However, the slave will ignore its programmed mode and use that of the master. This also applies to any parameters in the mode menu (Voltage Limit, Connect Delay, and so on). The following pages compare the various functions of each input mode.
Operation NOTES: IMPORTANT: The inverter will draw energy from the batteries when the loads exceed the appropriate AC Limit. With sustained loads and no other DC source, the batteries may discharge to the Low Battery Cut-Out point. The inverter will shut down with a Low Battery error. (See pages 23 and 58.) To prevent the loss of power, load use should be planned accordingly. IMPORTANT: A “noisy” or irregular AC source may prevent Support from working normally.
Operation NOTES: The inverter has a delay before selling will begin. This function, the Re-Connect Delay Timer, has a default setting of five minutes. During this time, the inverter will not connect to the utility grid. The timer is adjustable in the Grid Interface Protection menu (see below). Upon initial connection to the utility grid, the inverter may be required to perform a battery charging cycle. This may delay the operation of the grid-interactive function.
Operation The utility may simply name a standard to be followed, as with UL1741 for the United States. It may be necessary to look up the requirements for a local standard and program them accordingly.
Operation Backup Failure The Backup mode is intended for systems that have utility grid available as the primary AC source. This source will pass through the FXR inverter’s transfer circuit and will power the loads unless utility power is lost. If utility grid power is lost, then the inverter will supply energy to the loads from the battery bank. When the utility power returns, it will be used to power the loads again.
Operation Mini Grid mode is also incompatible with the Grid Use Time and Load Grid Transfer functions of the MATE3 system display. These functions do not have similar priorities to Mini Grid or HBX, but they do control the inverter’s connection and disconnection with the grid. Mini Grid should not be used with these functions. When deciding whether to use Mini Grid mode or HBX, the user should consider the aspects of each. Mini Grid logic is based in the FXR inverter.
Operation NOTES: IMPORTANT: Setting DoD Volts too low will severely discharge the batteries. The battery bank may not have sufficient reserve to provide backup in the event of a grid failure. To prevent the loss of power, load use and the DoD Volts setting should be planned accordingly. If the renewable energy source is not greater than the size of the inverter loads, this mode will not work well over time. The renewable source must be capable of charging the batteries as well as running the loads.

Operation NOTES: 22 900-0167-01-00 Rev B
Operation Description of Inverter Operations The items in this section are operations common to all FXR inverters. These are used in most or all of the input modes described in the preceding section. Some of the items in this section are functions which can be manually selected, enabled, or customized. Other items are general topics or applications for the inverter. These items may not have their own menus, but their activity can still be influenced or optimized by changing certain settings.
Operation Output Voltage: The AC output voltage can be adjusted. Along with small changes, this allows the inverter to be used for different nominal voltages such as 100 Vac and 127 Vac. IMPORTANT: The output voltage can be adjusted to a different nominal value for a particular region. Making this change will not affect the default input voltage range accepted by the inverter from an AC source. The input range must be adjusted manually. These changes should be made at the same time.
Operation NOTE: Increment sizes are difficult to define due to varying load characteristics. However, the default setting, 30 increments, is approximately sufficient to detect the load of one compact fluorescent light (CFL). A load which draws this amount or greater will “wake up” the inverter. Search mode is not particularly useful with loads requiring continuous power. (These loads include clocks, answering machines, and similar devices.
Operation allows certain models to sell power using the input connection. The Support mode can use battery power to assist a smaller AC source. When GridZero mode is selected, the battery charger cannot be used. See page 21 for descriptions of these and other input modes. AC Current Settings A A A The AC current settings, Grid Input AC Limit and Gen Input AC Limit, control the amount of current that the inverter draws from the source. Adjust these settings to match the input circuit breakers.
Operation The voltage limits can be adjusted to allow (or exclude) a source with weak or irregular voltages. These items are adjustable in the appropriate menu of the MATE3 (Grid AC Input Mode and Limits or Gen AC Input Mode and Limits). The settings are titled Voltage Limit Lower and Upper. There can be side effects to changing the range of allowed voltages. Each of the AC input selections has a settable Connect Delay.
Operation Generator Input A generator should be sized to provide enough power for all inverters, both for loads and for battery charging. The generator’s voltage and frequency must match the inverter’s acceptance settings. It is usually recommended that the generator be sized at twice the wattage of the inverter system. 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.
Operation Battery Charging 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. Charge Current Batteries or battery banks usually have a recommended limit on the maximum current used for charging. Often this is calculated as a percentage or fraction of the battery capacity, represented by “C”.
Operation Limiting Charge Current (Multiple Inverters) It is not advisable to set Charger AC Limit less than 12 Aac in a stacked system. The Power Save function requires the master to activates the slave chargers in sequence only when the charge current exceeds 11 Aac. If the setting is less than 12, Power Save will not activate any other chargers. For more information on this function, see the Power Save section beginning on page 43.
Operation Advanced Battery Charging (ABC) Advanced battery technologies such as lithium-ion and sodium-sulfur may require very different settings from the inverter’s defaults or the three-stage cycle in general. The Charging Steps section describes the individual selections and behavior. All charger settings are adjustable for different priorities. For example, the Float voltage could be set higher than the Absorption voltage, or a step could be completely skipped.
Operation Time limit: Absorb Time setting. The charger does not necessarily run through its full duration if it retained time from a previous charge cycle. The timer counts down from the inception of the Absorption stage until it reaches zero. The time remaining can be viewed in the system display. The Absorption timer does not reset to its maximum amount, or to zero, when AC power is disconnected or reconnected.
Operation Time limit: Float Time setting. The charger will go Silent once the timer has expired (if another stage is not still in progress.) The Float timer is reset to its maximum amount whenever the batteries decrease to the Re-Float Voltage setting. NOTE: The Float timer begins running any time the battery voltage exceeds the Float Voltage set point. This usually means that it begins running during the Bulk stage, once the battery voltage rises above that level.

Operation Cycle 3 AC Loss Cycle 5 Cycle 4 AC Loss Bulk Abs.
Operation Equalization Equalization is a controlled overcharge that is part of regular battery maintenance. Equalization brings the batteries to a much higher voltage than usual and maintains this high voltage for a period of time. This has the result of removing inert lead sulfate compounds from the battery plates. It also reduces stratification by circulating the electrolyte. Equalization follows the same pattern as standard three-stage charging, as shown in the figures on page 30.
Operation Battery Temperature Compensation Battery performance will change when the temperature varies above or below room temperature (77°F or 25°C). Temperature compensation is a process that adjusts battery charging to correct for these changes. When a battery is cooler than room temperature, its internal resistance goes up and the voltage changes more quickly. This makes it easier for the charger to reach its voltage set points.
Operation Offset Offset is an automatic operation which occurs in certain conditions. It is not a programmable function. This operation uses excess battery energy to power the loads when an AC source is present. The system can take advantage of renewable energy sources, “offsetting” dependence on the AC source. The battery voltage increases as a renewable energy source charges the batteries. When the voltage exceeds a designated reference voltage, the FXR inverter begins inverting.
Operation Multiple-Inverter Installations (Stacking) Multiple inverters in a single system can support larger loads than a single inverter. Installing inverters in this configuration is called “stacking”. Stacking refers to how inverters are wired within the system and programmed to coordinate activity. Stacking allows inverters to work together as one system. Each inverter is programmed to power an individual phase of the system and to operate at certain times.
Operation Stacking Configurations Each inverter must be assigned a particular mode in the Stack Mode menu. In the figures for each configuration below, the mode names are shown next to each inverter. For example, Figure 10 shows Master for the first (L1) inverter in a series-stacked system. The designation for the L2 inverter is L2 Phase Master. Figure 11 shows Master for the first inverter in a parallel-stacked system and Slave for the remaining inverters.
Operation LOAD PANEL Master 2.0 kVA 120 Slave Slave 2.0 kVA 120 Vac Figure 11 6.0 kVA 120 Vac 2.0 kVA 120 Vac Example of Parallel Stacking Arrangement (Three Inverters) Series/Parallel Stacking (Quad-Stack or Larger) In series/parallel stacking, inverters create separate 120 Vac4 output legs and 240 Vac collectively, as in series stacking. However, in this configuration, each output has parallel inverters. One output contains the master; the other uses a subphase master.
Operation Three-Phase Stacking In three-phase stacking, inverters create three separate 120 Vac5 output legs in a wye configuration. The three legs operate independently of each other. 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. Up to nine inverters, three per phase, may be installed in a three-phase arrangement.
Operation Power Save Each FXR inverter consumes 34 watts of idle power while it remains on, even if it is not actively inverting or charging. The Power Save function allows the option to put part of a parallel system into a quiescent state known as Silent mode. This mode minimizes the idle consumption. The inverters will come on again when the loads require power. (The term “Silent” is also used in an unrelated context during battery charging. See page 32.
Operation Master Power Save Level appears on an inverter which is set as master (the default setting). The range of rank numbers is 0 to 10. The default value is 0. The master is normally left at this value. The Master Power Save Level function is used for the master inverter on Port 1. It is also used for any subphase masters in a series or three-phase system. The ranking of a subphase master is treated the same as the master. If the master is set at 0, subphase masters should also be 0.
Operation Master Port 1 Master Power Save = 0 <12 Aac On Off 12 Aac On 24 Aac On Slave 2 Port 3 Slave Power Save = 2 Slave 3 Port 4 Slave Power Save = 3 Off Off On Off Off On On Off 36 Aac On On On On 16 Aac On On On Off Figure 16 Slave 1 Port 2 Slave Power Save = 1 Power Save Priority (Parallel) The fourth line shows that loads of 36 Aac or more (approximately 4 to 4.5 kW) are present on the system. This load causes all four inverters to be activated.
Operation Auxiliary Terminals The FXR inverter has a 12V AUX output which can respond to different criteria and control many operations. These terminals provide a 12 Vdc output that can deliver up to 0.7 Adc. The AUX output has three states: continuous Off, continuous On, and Auto, which allows that output to be activated using the automatic auxiliary functions. (All functions are defaulted to Auto.) These items are based in the inverter and accessed using the system display.
Operation Settable Gen Alert parameters include: Low and high DC voltage On and off delay Gen Alert control logic is located in the inverter. It has the advantage of functioning when the system display is removed. However, it may not completely charge the batteries and does not have all the advantages of the Advanced Generator Start (AGS) function that is found in the system display. For many users, the AGS function may prove more useful than Gen Alert.
Operation When battery voltage rises above a settable high voltage level, the AUX output is activated after a settable delay. The AUX output controls a larger relay, which allows current to flow from the batteries to a dedicated AC load when energized. Diversion is usually used to regulate battery charging. The AC device is usually wired to the output or load panel and must be left on. It must be sized to dissipate all of the energy from the renewable source if necessary.
Operation System Display-Based Functions A system display such as the OutBack MATE3 can provide functions not available in the inverter. These functions are summarized here to provide a better idea of overall system capabilities. The system display must be present for these functions to operate. If a function is set up (or already in operation) but the system display is removed, the function will not operate.
Operation Grid Use Time The inverter system is capable of connecting to, or disconnecting from, the utility grid based on time of day. It can also be programmed to connect at different times on weekdays and on weekends. Load Grid Transfer The inverter system is capable of connecting to, or disconnecting from, the utility grid based on load size. This avoids undesirable battery discharge from excessive loads.
Metering MATE3 Screens The MATE3 system display can monitor the FXR inverter and other networked OutBack devices. From the Home screen, the “soft” key accesses the screens for monitoring the inverter. Inverter Soft Key Figure 18 Home Screen Inverter Screen The Inverter soft key opens a screen showing the inverter operating mode, battery voltage, and status of several AC operations. The soft key will select other networked OutBack inverters, if present.
Metering Load displays kilowatts and AC amperage consumed by devices on the inverter’s output. It can be the same as Invert. Buy displays the kilowatts and AC amperage brought into the inverter’s input for both charging and loads. This is usually a total of Charge and Load. Battery displays the uncompensated battery voltage. AC Out displays the AC voltage measured at the inverter’s output. If an AC source is present, this reading is usually the same as AC In.
Troubleshooting Basic Troubleshooting Table 7 is organized in order of common symptoms, with a series of possible causes. Each cause also shows possible troubleshooting remedies, including system display checks where appropriate. These instructions are for use by qualified personnel who meet all local and governmental code requirements for licensing and training for the installation of electrical power systems with AC and DC voltage up to 600 volts.
Troubleshooting Table 7 Symptom One or more units have no output but others do (in multiinverter system). Will not connect to the AC source. 8 Troubleshooting Possible Cause Possible Remedy Unit is slave and is in Silent mode. MATE3 system display only: Check Power Save levels in the Inverter Stacking menu and test with loads. Determine if the inverter comes on at the appropriate levels. (If this setting was intentional, then no action is required.) No AC input.
Troubleshooting Table 7 Symptom Troubleshooting Possible Cause Possible Remedy Charge complete or nearly complete. Check the DC voltage and charging stage using the MATE3, if present. Confirm with DC voltmeter. MATE3’s DC meter reads significantly higher than actual battery voltage. Check the DC voltage on the inverter’s DC terminals. If different from the MATE3 reading, the inverter could be damaged. Otherwise, check the DC voltage on batteries with a voltmeter.
Troubleshooting Table 7 Symptom Inverter does not perform the Offset function when expected. Troubleshooting Possible Cause Possible Remedy Incorrect input mode. Offset does not function in Generator, UPS, and Backup modes. Specific mode only offsets under particular conditions. Support mode will perform the Support function based on load. This may appear as Offset without reaching the reference voltage. GridZero mode will perform Offset based on the DoD Volts setting.
Troubleshooting Table 7 Symptom Inverter clicks repeatedly. AC output voltage rises or drops to unusual levels with every click. Possible Cause Possible Remedy Inverter’s output has been connected to its input. Voltage shifts are the result of trying to match its own voltage. Disconnect the wires from the inverter’s AC input or AC output terminals, or both. If the problem immediately disappears, it is an external wiring issue.
Troubleshooting Error Messages An error is caused by a critical fault. In most cases when this occurs, the ERROR indicator will illuminate and the inverter will shut down. (See page 11 for the FXR inverter’s LED indicators.) The MATE3 system display will show an event and a specific error message. This screen is viewed using the MATE3 Home screen’s soft keys. (See the MATE3 manual for more instructions.) One or more messages will display Y (yes). If a message says N (no), it is not the cause of the error.
Troubleshooting Warning Messages A warning message is caused by a non-critical fault. When this occurs, the ERROR indicator will flash, although the inverter will not shut down. (See page 11 for the FXR inverter’s LED indicators.) The MATE3 system display will show an event and a specific warning message. This screen is viewed using the MATE3 Home screen’s soft keys. (See the MATE3 manual for more instructions.) One or more messages will display Y (yes).
Troubleshooting Table 9 Warning Troubleshooting Message Definition Possible Remedy Fan Failure The inverter’s internal cooling fan is not operating properly. Lack of cooling may result in derated inverter output wattage. Turn the battery disconnect off, and then on, to determine if the fan self-tests. After this test, contact OutBack Technical Support for the next step.14 (The next step will depend on the results of the test.
Troubleshooting Disconnect Messages Disconnect messages explain why the inverter has disconnected from an AC source after previously being connected. The unit returns to inverting mode if turned on. The Last AC Disconnect screen is viewed using the AC INPUT hot key on the MATE3. One or more messages will display Y (yes). If a message says N (no), it is not the cause of the disconnection. The MATE3 system display may generate a concurrent event and warning message following the disconnection. (See page 59.
Troubleshooting Sell Status Sell Status messages describe conditions relating to the inverter’s grid-interactive mode. This screen is viewed using the MATE3 Home screen’s soft keys. (See the MATE3 manual for more instructions.) One or more messages will display Y (yes). If a message says N (no), it is not the cause of the disconnection. If the inverter has stopped selling or charging unexpectedly, this screen may identify the reason.

Specifications through compliance testing and refer to exporting power to a simulated utility source of less than 1% voltage total harmonic distortion (THD). The inverter output exceeds the minimum power factor of 0.85 with a typical power factor of 0.96 or better. The individual harmonics do not exceed the limits specified in Table 3 of IEEE 1547 Section 4.3.3. The THD of the root mean square (RMS) current is less than 5%.
Specifications Summary of Operating Limits Severe conditions cause the inverter to limit its output or shut down for protection. The most common conditions are high voltage, low voltage, and temperature. The limits for these conditions are summarized in Table 20. See pages 58 and 60 for more information on these conditions and the warning or error messages which accompany them.
Specifications 4. Adjust the master inverter’s Charger AC Limit setting to the designated amount (in Aac). 5. Turn off the chargers for all inverters that exceed the number shown as On. In a stacked system (using the HUB communications manager), chargers on higher-numbered HUB ports should be turned off first. Slave chargers should be turned off before turning off any subphase masters. (See page 39 for information on stacking.
Specifications To calculate the chargers and settings: 1. Look up the values for A, B, and C. A = the battery bank’s maximum charge current (in Adc) from the battery manufacturer. B = the maximum DC output of the appropriate inverter model. This is taken from Table 22. C = the maximum AC input of the appropriate inverter model. This is taken from Table 22. 2. Select a value for D and perform the following calculation. D = the Charger AC Limit setting. This value must be 12 or higher.
