  • Page 8: Welcome To Outback Power Technologies

    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.
  • Page 9: Inverter Controls

    The FXR inverter has no external controls. It can operate normally without an external control or interface. Basic modes and settings are pre-programmed at the factory. (See the menu tables beginning on page 76.) However, external communication devices such as the OutBack MATE3 or AXS Port can be used to operate or program the inverter.
  • Page 10: On/Off Switch

     The FXR inverter is only compatible with the MATE3 System Display and Controller. It is not intended for use with the OutBack MATE or MATE2 products.  The FXR inverter can use the OPTICS RE online tool as a system display.
  • Page 11: Commissioning

    Commissioning 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.

  • Page 14: Firmware Updates

    Inverters automatically update one at a time beginning with the highest port. Each requires about 5 minutes. Updates to the inverter’s internal programming are periodically available at the OutBack website www.outbackpower.com. If multiple inverters are used in a system, all units must be upgraded at the same time.
  • Page 15: Operation

    If they have any loads, a charging source, or are at another temperature, their voltage may not reflect their true state. The OutBack FLEXnet DC is a battery monitor that can be added to the system to provide accurate measurements.
  • Page 16: Status Indicators

    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).
  • Page 17: Inverter Functionality

    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.
  • Page 18: Generator

    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 43.) 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.
  • Page 19: Grid Tied

    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.
  • Page 20: Grid Interface Protection Menu

    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).
  • Page 21: Frequency And Phase Coordination

    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. STAGE 1 Voltage (basic settings) Frequency Trip ...
  • Page 22: Backup

    Operation Failure Backup 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.
  • Page 23: Gridzero

    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.
  • Page 24 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. ...

  • Page 27: Description Of Inverter Operations

    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.
  • Page 28: Ac Frequency

    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.
  • Page 29: Input

    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. ...
  • Page 30: Ac Current Settings

    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 25 for descriptions of these and other input modes. AC Current Settings 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.
  • Page 31 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.
  • Page 32: Generator Input

    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.
  • Page 33: Battery Charging

    75 Adc. (75 ÷ 2.5 = 30 Aac) Bank consists of 12 x OutBack EnergyCell 200RE VRLA batteries in series/parallel for a 24-volt system. Recommended maximum charge current is 90 Adc. (90 ÷ 5 = 18 Aac) The maximum DC charge rate for FXR models is specified in Table 14 on page 67.
  • Page 34: Charge Cycle

    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.
  • Page 35: Advanced Battery Charging (Abc)

    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.
  • Page 36: Float Stage

    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.
  • Page 37: New Charging Cycle

    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.

  • Page 40: Equalization

    Equalization is not normally performed on nickel-technology batteries or any sort of sealed battery. CAUTION: Battery Damage  Do not equalize OutBack EnergyCell batteries of any model.  Do not equalize any sealed battery types (VRLA, AGM, Gel, or other) unless approved by the manufacturer.
  • Page 41: Battery Temperature Compensation

    A 48 Vdc system with batteries at 40°C will compensate its charging to 1.8 Vdc lower than the set points. Slope Some batteries require different amounts of compensation. The OutBack FLEXmax Extreme charge controller has an adjustable rate of compensation (“slope”) and is not limited to 5 mV. The FLEXmax Extreme can be networked with the inverter with the HUB Communications Manager.
  • Page 42: Offset

    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.
  • Page 43: Multiple-Inverter Installations (Stacking)

    Each inverter is programmed to power an individual phase of the system and to operate at certain times. This order is assigned using a system display such as the OutBack MATE3. FXR stacking includes “series” (split-phase), “parallel” (single-phase), “series/parallel” (split-phase) and “three-phase” configurations.
  • Page 44: Stacking Configurations

    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 11 shows Master for the first (L1) inverter in a series-stacked system. The designation for the L2 inverter is L2 Phase Master.
  • Page 45: Series/Parallel Stacking (Quad-Stack Or Larger)

    Operation LOAD PANEL Master Slave Slave 6.0 kVA 120 Vac 2.0 kVA 120 2.0 kVA 120 Vac 2.0 kVA 120 Vac Figure 12 Example of Parallel Stacking Arrangement (Three Inverters) Series/Parallel Stacking (Quad-Stack or Larger) In series/parallel stacking, inverters create separate 120 Vac output legs and 240 Vac collectively, as in series stacking.
  • Page 46: Three-Phase Stacking

    Operation Three-Phase Stacking In three-phase stacking, inverters create three separate 120 Vac 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.
  • Page 47: Power Save

    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.
  • Page 48 For more information on charging with stacked inverters, see page 33. If other adjustments are required to the maximum charge rate, see page 73. Figure 17 shows a system of four FXR2012A inverters (the master and three slaves). These inverters in a parallel system with a common load bus.
  • Page 49: Figure 17 Power Save Priority (Parallel)

    16 Aac are distributed among the remaining three inverters. If the loads decreased to 12 Aac, a second slave would go silent. Figure 18 shows a system of six FXR2012A inverters. In this example the inverters have been stacked in a split-phase system. The master inverter is on the L1 output while a subphase master is on L2.
  • Page 50: Auxiliary Terminals

    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.
  • Page 51 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.
  • Page 52: Table 5 Aux Mode Functions

    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.
  • Page 53: System Display-Based Functions

    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.
  • Page 54: Grid Use Time

    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.
