900-0112-01-00 Rev B 7 Introduction Welcome to OutBack Power Technologies Thank you for purchasing the OutBack International Se ries GFX Inverter/Charger. This product offers a complete power conversion system between batteries and AC power. It can provide backup power or complete off-grid service. ¾ Battery-to-AC inverting which delivers 230 Vac [...]

Introduction 8 900-0112-01-00 Rev B System Display and Controller The GFX inverters have no external controls. They can operate normally without an external control or interface. Basic modes and settings are pre-progr ammed at the factory. (See page 47 for default settings.) The MATE and MATE2 System Display and Controller (sold separ ately) are Ou[...]

900-0112-01-00 Rev B 9 Commissioning Functional Test Pre-startup Procedures 1. Ensure all DC and AC overcurrent de vices are opened or turned off. 2. Double-check all wiring connections. 3. Inspect the work area to ensure tools or debris have not been left inside. 4. Verify battery voltage using a digital voltmeter (DVM). Confirm the voltage is cor[...]

Commissioning 10 900-0112-01-00 Rev B continued from previous page.... 5. If the INVERTER LED (green) is not illuminated, turn on the inverter using the system display or external switch. 6. Check the STATUS LEDs. Confirm that the INVERTER LED (green) is illuminated. 7. Using a DVM, verify 230 Vac be tween the AC HOT OUT and AC NEUTRAL OUT terminal[...]

900-0112-01-00 Rev B 11 Operation LED Indicators Figure 4 LED Indicators BATTERY LEDS The battery LEDs show the approximate battery state. (See IMPORTANT note below.) The BATTERY LEDs are independent of STATUS LEDs. Any STATUS LED could accomp any any BATTERY LED ba sed on certain conditions. Commo n combinations are noted. ¾ A GREEN LED means the[...]

Operation 12 900-0112-01-00 Rev B STATUS LEDS GREEN ¾ Solid: The inverter is ON and providing power. If accompanied by solid ye llow LED, unit is selling power to the utility grid. (See page 24 for a description of the Sell function.) ¾ Flashing: The inverter has been tur ned ON but is idle. May be accompanied by the yellow LED. If not accompanie[...]

Operation 900-0112-01-00 Rev B 13 Description of Functions All items identified as settable or adjustable have set points which can be accessed using the remote system display. (See the system display manual fo r instructions on loc ating these set points.) The default settings and ranges of adjustment are listed near the end of this book, beginnin[...]

Operation 14 900-0112-01-00 Rev B Search An automated search circuit is available to minimi ze 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. In ef[...]

Operation 900-0112-01-00 Rev B 15 AC Current Settings The AC current settings control the amount of curren t that the inverter draws from the source(s). The amount of current is controlled by the grid or ge nerator limit settings. These settings should be adjusted to match the size of the input circuit breaker or input conductor. In the system disp[...]

Operation 16 900-0112-01-00 Rev B Generators A generator should be sized to provide enough power for both loads and batt ery charging. ¾ The generator needs a single circuit w hich is sized to provide current to all inverters on a given phase or leg. ¾ It is usually recommended that the generator be sized at twice the wattage of the inverter syst[...]

Operation 900-0112-01-00 Rev B 17 Input Support A system display is required to control this function. When this function is enabled, the inverter limits the current draw from an AC source, augmenting it with additional current from the batteries when necessary. This helps prevent overloading a small AC circuit or generator during short-term use. I[...]

Operation 18 900-0112-01-00 Rev B 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 un dercharged or overcharged. Figure 5 Charging Stages Over Time[...]

Operation 900-0112-01-00 Rev B 19 The initial DC current is the maximum current the ch arger can deliver. It will begin at the charger’s specified maximum, but will gradually decrease as the voltage increases. This is a tradeoff in wattage and is normal for the charger. Absorption Stage This is the second stage of chargi ng. It is a constant-volt[...]

Operation 20 900-0112-01-00 Rev B Silent This is not a charging stage, but a quiescent period between stages. The inverter remains on the AC source, but the charger is inactive. It enters this condition upon completing the Absorption stage, or when there is not enough energy to sustain selling. The term “Silent” is also used in the context of s[...]

Operation 900-0112-01-00 Rev B 21 Figure 6 Repeated Charging Cycles New Charging Cycle If the AC source is lost or disconnected, the unit wi ll return to inverting mode if enabled. The battery voltage will begin to decrease due to loads or na tural loss. When the AC source is restored, the inverter will return to the charging cycle. If the batterie[...]

Operation 22 900-0112-01-00 Rev B will always run for the full Absorption period if the batteries dropped below the appropriate voltage for that amount of time. If significant battery dr ain caused them to drop below the set points for doubling or quadrupling the rate, it may run for the full Absorption period even after a lesser amount of time. Th[...]

Operation 900-0112-01-00 Rev B 23 The inverter, when equipped with the Remote Temper ature Sensor (RTS), will compensate for changes in temperature. The RTS is attached to a single battery near the center of the bank, to achieve a representative temperature. If installed in a multiple -inverter system, only a single RTS is necessary. It must plug i[...]

Operation 24 900-0112-01-00 Rev B Selling IMPORTANT: Selling power to the utility company re quires the authori zation of the local electric jurisdiction. How the local util ity company handles this will depend on their policies on this issue. Some may pay for power sold; others may issue credit. Some policies may prohibit the us e of this mode. Pl[...]

Operation 900-0112-01-00 Rev B 25 Multiple-Inverter Installations (Stacking) Multiple inverters in a single system can support larger loads than a single inverter can handle. Installing inverters in this configuration is called “stacking”. Stacking inverters does not refer to physically placing one on top of anoth er. It refers to how they are [...]

Operation 26 900-0112-01-00 Rev B Parallel Stacking (Dual-Stack and Larger) In parallel stacking, two or more inverters are stac ke d to create a single, common 230 Vac output. ¾ The master provides the pri mary output. The slaves ar e connected to the same output and assist the master. ¾ The slave inverters can be programmed to activate on deman[...]

Operation 900-0112-01-00 Rev B 27 Power Save Levels Depending on the model, each inverter consumes approximately 20 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 some or all slave inverters into a quiescent state known as Silent mode. This mode minimizes t[...]

Operation 28 900-0112-01-00 Rev B Auxiliary Terminals The inverter’s AUX terminals provide a 12 Vdc output that can deliver up to 0.7 Adc to control external loads. The AUX LED (see page 11) illuminates when this output is present. Typical loads include signaling a generator to start, sending a fault alarm si gnal, or running a small fan to cool [...]

Operation 900-0112-01-00 Rev B 29 ¾ Fault activates the AUX output when the in verter shuts down due to an err or condition (see page 37). It can activate a light or alar m to show that the inverter has failed. With the appropriate devices, it could send an alarm signal through a radio, pa ger, or telephone dialer. ∼ This function does not have [...]

Operation 30 900-0112-01-00 Rev B System Display-Based Functions Advanced Generator Start (AGS) As noted under the Gen Alert feature (see page 28), th e system is capable of starting a generator. Gen Alert simply starts and stops the generator based on battery voltage. For more advan ced control, the inverter system can use the Advanced Gene rator [...]
