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. This product is only serviceable by qualified personnel. Do not use this product without reading the FXR Series Inverter/Charger Installation Manual.
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 Inverter Functions Battery-to-AC inverting which delivers power to run backup loads and other functions Provides single-phase output Adjustable range of output voltage Settable nominal output frequency AC-to-battery charging (OutBack systems are battery-based) Accepts a wide variety of single-phase AC sources Uses battery energy stored from renewable resources Can utilize stored energy from many sources (PV arrays, wind turbines, etc.
Introduction Inverter Controls The FXR inverter has no external controls pre-installed. It can operate normally without an external control or interface. Basic modes and settings are pre-programmed at the factory. (See page 66 for default settings.) However, certain products can monitor, operate, or program the inverter. These include OPTICS RE and the MATE3 class of system display See the FXR Series Inverter/Charger Installation Manual for information on wiring a manual on/off switch.
Operation LED Indicators AUX Indicator (see page 41) Battery Indicators Status Indicators Figure 2 LED Indicators Battery Indicators The BATTERY LED indicators show the approximate battery state. (See IMPORTANT below.) A green indicator (FULL) means the batteries have an adequate charge at that time. It does not always mean they are full. It may be accompanied by a yellow STATUS indicator when an AC source is charging. A yellow indicator (OK) means the batteries are somewhat discharged.
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.
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 Description of AC Input Modes These modes control aspects of how the inverter interacts with AC input sources. Each mode is intended to optimize the inverter for a particular application. The names of the modes are Generator, Support, Grid Tied, UPS, Backup, Mini Grid, and GridZero. The modes are summarized and compared in Table 2. See page 21. When multiple inverters are stacked together in parallel, the master inverter’s input mode is imposed on all slaves.
Operation Support The Support mode is intended for systems that use the utility grid or a generator. In some cases the amount of current available from the source is limited due to size, wiring, or other reasons. If large loads are required, the FXR inverter augments (supports) the AC source. The inverter uses battery power and additional sources to ensure that the loads receive the power they demand. In a MATE3-class system display, the Grid Input AC Limit dictates the maximum AC draw for the Grid input.
Operation Grid Tied IMPORTANT: Selling power to the utility company requires the authorization of the local electric jurisdiction. How the utility company accommodates this will depend on their policies on the issue. Some may pay for power sold; others may issue credit. Some policies may prohibit the use of this mode altogether. Please check with the utility company and obtain their permission before using this mode. The Grid Tied mode allows the FXR inverter to become grid-interactive.
Operation Grid Interface Protection Menu Grid-interactive requirements vary in different locations around the world. The grid-interactive settings are adjustable in the Grid Interface Protection and Grid Support menus. These menus are only available with installer-level access. These settings are generally controlled by the local authorities or interconnection agreement and should not be altered by the end user. The installer password must be changed from the default to access these settings.
Operation Multi-Phase Coordination Several other inverter adjustments are located in the Grid Interface Protection menu. These sensitive items can only be changed with installer-level access. The FXR inverter’s stacking function includes the option called Multi-Phase Coordination. The selectable menu item is Coordinated AC Connect/Disconnect. The default setting is No. If selected to No, the inverters will connect independently to the AC source.
Operation Mini Grid In Mini Grid mode, the FXR inverter automatically rejects an AC source and runs solely from battery (and renewable) energy. The inverter only connects to the AC source (usually the utility grid) when the batteries run too low. The inverter runs on battery-supplied power for as long as the batteries can be sustained. It is expected that the batteries will also be charged from renewable sources such as PV.
Operation GridZero In GridZero mode, the FXR inverter remains grid-connected, but prioritizes the use of battery or renewable sources to run loads. It uses only renewable energy to recharge the batteries. The inverter tries to “zero” the grid use, drawing on AC power only when needed to supplement stored DC sources. Note that the inverter draws up to 1 Aac regardless of the DC sources. In a MATE3-class system display, the selectable options are DoD Volts and DoD Amps.
Operation Table 2 Mode Summary Generator Accepts power from an irregular or low-quality AC source Summary of Input Modes Benefits Cautions Intended Charger Can use AC that may be unusable in other modes Can charge even with a poor generator or low-quality AC source Will pass irregular or low-quality power to the output; could damage sensitive loads Offset unavailable Source: Generator Loads: Nonsensitive devices Performs threestage charge and goes silent as specified by settings Suppor
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 Low Battery Cut-In: The recovery point from Low Battery Cut-Out. When the DC voltage rises above this point for 10 minutes, the error will clear and the inverter will resume functioning. This item is adjustable. Connecting an AC source for the inverter to charge the batteries will also clear a low battery error. 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.
Operation Search An automated search circuit is available to minimize the power draw when no loads are present. When enabled, the inverter does not always deliver full output. The output is reduced to brief pulses with a delay between them. These pulses are sent down the output lines to see if a resistance is present. Basically, the pulses “search” for a load. If a load is detected on the output, the inverter’s output increases to full voltage so that it can power the load.
Operation Input When the input terminals are connected to a stable AC source, the FXR inverter will synchronize itself with that source and use it as the primary source of AC power. Its transfer relay will engage, linking the AC source directly with the inverter’s output. It can also use the source to charge batteries. (See Battery Charging on page 29.) The loads powered by the inverter must not exceed the size of the inverter’s transfer relay.
Operation AC Source Acceptance The input source must meet the following specifications to be accepted. This is true in all modes except Grid Tied: Voltage (GRID input selection): 108 to 132 Vac Voltage (GEN input selection): 108 to 140 Vac Frequency (both input selections): If the output frequency is set to 60 Hz (default), the input acceptance range is 54 to 66 Hz. If output frequency is set to 50 Hz, the input range of acceptance is 45 to 55 Hz.
Operation Multiple Inverters In a stacked system, whenever the master inverter senses acceptable AC input, it orders the other inverters to transfer to the AC source. The AC source is expected to deliver power (in the appropriate phase) to the input of all inverters. Subphase master and slave inverters cannot transfer until the master does. A subphase master inverter may receive this command without receiving acceptable AC input.
Operation Transfer The inverter uses a transfer relay to alternate between the states of inverting and of accepting an AC source. Until the relay energizes, the output terminals are electrically isolated from the input. When it closes, the input and output terminals become electrically common. When the relay changes states, the physical transfer delay is approximately 16 milliseconds. CAUTION: Equipment Damage Current draw in excess of the transfer relay rating can damage the transfer relay.
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 inverter to activate 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 in the Installation Manual.
Operation Advanced Battery Technologies 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 cycle. The timer counts down from the inception of 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 If installed in a system networked with a HUB Communications Manager, only a single RTS is necessary. In most cases the RTS must be plugged into the master inverter. A system display must be present for the compensation values to be shared to all devices. NOTE: In the FLEXmax 100 or FLEXmax Extreme charge controller, the rate of compensation is adjustable. (See Slope below.
Operation Offset Offset is an automatic operation which occurs in certain conditions. It is not a programmable inverter 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 battery voltage exceeds a designated reference voltage, the FXR inverter begins inverting.
Operation Grid Support The FXR inverter meets the definition of a “Grid Support Utility-Interactive Inverter/Converter” as described by UL 1741 SA. Grid support functionality makes use of the inverter’s capabilities to prevent destabilization of the utility grid. Grid Support functionality is only available in the Grid Tied and GridZero input modes. When either mode is selected, the settings within the Grid Support menus are active.
Operation The settings for each item will vary depending on the standards being applied. Not all functions are enabled. When a particular standard is applied, the settings will be pre-loaded accordingly. The screen in Figure 8 shows which functions are enabled.
Operation Auxiliary Terminals The FXR inverter has an auxiliary (“AUX“) output that responds to different criteria to control certain 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 FXR 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 AC Divert activates the AUX output to divert (or “dump”) excess renewable energy to an AC load, usually an AC device powered by the inverter itself. This prevents overcharging of the batteries. This function can serve as rough charge regulation for an external charging source. When battery voltage rises above a settable high voltage level, the AUX output is activated after a settable delay.
Operation NOTES: 44 900-0167-01-01 Rev A
Metering MATE3-Class System Display Screens A MATE3-class system display can monitor the inverter and other networked devices. From the Home screen, the “soft” key accesses the inverter monitoring screens. Inverter Soft Key Figure 9 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 6 is organized in order of common symptoms, with a series of possible causes. Each 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 6 Symptom One or more units have no output but others do (in multiinverter system). Will not connect to the AC source. Possible Cause Possible Remedy Unit is slave and is in Silent mode. 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. Check the AC voltage on the inverter’s input terminals.
Troubleshooting Table 6 Symptom Low charge rate. Will not sell power to the utility grid. Reduced power sold to the utility grid. Inverter does not perform the Offset function when expected. 900-0167-01-01 Rev A Troubleshooting Possible Cause Possible Remedy Charge complete or nearly complete. Check the DC voltage and charging stage using the system display, if present. Confirm with DC voltmeter. System display DC meter reads significantly higher than actual battery voltage.
Troubleshooting Table 6 Symptom Troubleshooting Possible Cause Possible Remedy Unusual voltage on hot or neutral output line. System neutral and ground may not be bonded. Test AC HOT OUT and AC NEUTRAL OUT terminals with AC voltmeter. (See page 47.) These measurements should give full voltage. Test neutral and ground connections. This measurement should read zero volts. Any other result means neutral and ground are not bonded correctly.
Troubleshooting Table 6 Symptom Inverter clicks repeatedly. AC output voltage rises or drops to unusual levels with every click. Inverter hums loudly. System display may show messages for high battery voltage, low battery voltage, or backfeed error. Generator, external fan, etc. fails to start when signal is provided by AUX output. Advanced Generator Start (AGS) fails to activate when conditions are met (or starts when conditions are not met).
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.) A MATE3-class system display will show an event and a specific error message. This screen is viewed using the Home screen’s soft keys. (See the system display literature for more instructions.) One or more messages will display Y (yes).
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.) A MATE3-class system display will show an event and a specific warning message. This screen is viewed using the Home screen’s soft keys. (See the system display literature for more instructions.) One or more messages will display Y (yes).
Troubleshooting Table 8 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. If it does not, the unit may be damaged and requires repair. NOTE: The system can continue to operate if the inverter can be run at reasonable levels. External cooling may also be applied.
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 a MATE3-class system display. One or more messages will display Y (yes). If a message says N (no), it is not the cause of the disconnection. The system display may generate a concurrent event and warning message following the disconnection.
Troubleshooting Sell Status Sell Status messages describe conditions relating to the inverter’s grid-interactive mode. This screen is viewed using the Home screen’s soft keys on a MATE3-class system display. (See the system display literature 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.
