  • 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 one minute. 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 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 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 220 Vac and 240 Vac. IMPORTANT: The output voltage can 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.

    Operation 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. This is intended as a warmup period which allows an input source to stabilize before connection.

  • 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 34: Charge Cycle

    Operation Limiting Charge Current (Multiple Inverters) It is not advisable to set Charger AC Limit less than 6 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 5 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 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.)

  • Page 40: Equalization

    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.

  • Page 41: Battery Temperature Compensation

    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.

  • 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)

    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.

  • 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 inverter in a parallel-stacked system. The remaining inverters are designated Slave.

  • Page 46: 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 47 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 15 shows a system of four FXR2012E inverters (the master and three slaves). These inverters in a parallel system with a common load bus.

  • Page 48: Figure 15 Power Save Priority (Parallel)

    8 Aac are distributed among the remaining three inverters. If the loads decreased to 6 Aac, a second slave would go silent. Figure 16 shows a system of six FXR2012E inverters. In this example the inverters have been stacked in a three-phase system. The master inverter is on the Phase A output while subphase masters are on Phase B and Phase C.

  • Page 49: 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 50 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.

    Operation 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 energy from the renewable source if necessary. Diversion will turn off following a delay when a low DC voltage setting is reached. ...

  • Page 52: 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.
