Planning Applications The International Series GFX inverters are intended for on-grid, off-grid, and grid-interactive applications. These models are designed to use a battery bank to store energy. They can work in conjunction with photovoltaic (PV) panels to harvest solar energy, as well as wind turbines and other renewable sources. These sources charge the battery, which in turn is used by the inverter. In on-grid applications, grid power is used to run the loads.
Planning Renewable Energy The inverter cannot connect directly to PV, wind, or other renewable sources. The batteries are the inverter’s primary source of power. However, if these sources are used to charge the batteries, the inverter can use their energy by drawing it from the batteries. The renewable source is always treated as a battery charger, even if all of its power is used immediately. The renewable source must have a charge controller or some way to prevent overcharging.
Planning A generator should be sized to provide enough power for all the loads and the battery charging. Available generator power may be limited by ratings for circuit breakers and/or generator connectors. The generator must be able to provide current to all inverters on a given phase or leg. Minimum generator wattage* is usually recommended to be twice the wattage of the inverter system.

Installation Location and Environmental Requirements The International Series GFX inverters can be located outdoors, but OutBack still recommends that they be protected from the environment. If protected from the environment, the inverter can mount in any position or orientation. If exposed to the environment, it cannot be placed upside-down to ensure that water will not accumulate under the DC cover. (It can be mounted in any other position or orientation.
Installation Tools Required Wire cutters/strippers Torque wrenches Assorted insulated screwdrivers DVM or Voltmeter Mounting It is easier for two people to install the GFX inverter due to its weight. The unit must be secured with appropriate fasteners to a sturdy mounting surface capable of supporting its weight. OutBack cannot be responsible for damage if inadequate fasteners are used. The unit has four mounting holes, one in each corner.
Installation Terminals and Ports DC TERMINALS: Connect to battery cables and DC system. See page 19 for instructions. DC and AC GROUND TERMINALS: Connect to grounding system for both batteries and AC. See page 18 for instructions. CONTROL WIRING TERMINAL BLOCK: Receives control wires for a variety of functions, including automatic generator starting. See pages 23 and 24 for instructions and the International Series GFX Operator’s Manual for more information.
Installation Grounding WARNING: Shock Hazard The unit must be connected to a grounded, permanent wiring system. If a bond is made between neutral and ground make sure only one bond is present in the AC system at any time. Some codes require the bond to be made at the main panel only. WARNING: Shock Hazard For all installations, the negative battery conductor should be bonded to the grounding system at only one point. If the OutBack GFDI is present, it can provide the bond.
Installation DC Wiring CAUTION: Equipment Damage Never reverse the polarity of the battery cables. Always use correct polarity. CAUTION: Fire Hazard Always install a breaker, fuse, or protective device to protect the DC system.

Installation Install battery cable lug, nuts and washers in the order illustrated. The battery cable lug should be the first item installed on the stud. It should make solid contact with the mounting surface. Do not install hardware in a different order than shown. M8 x 1.
Installation AC Wiring Table 5 AC Conductor Size and Torque Requirements Conductor Size Recommendation Torque Requirements Minimum 6 mm2 (#10 AWG or 0.008 in2) 4.0 Nm (35 in-lbs) The AC Hot Out terminal connects to the load panel. It can carry up to 30 amps using the inverter’s transfer relay. Use the inverter wattage to determine actual maximum load. Size the breakers accordingly. The two Neutral terminals are electrically common. Use only one terminal if connecting to an external neutral bus.
Installation Accessory Wiring The AC Wiring Compartment Board has ports for both the Remote Temperature Sensor (RTS) and the system display. (The system display port is labeled MATE/HUB.) If a HUB is in use, it occupies the inverter’s MATE/HUB port. RTS port RTS cable (RJ11, 4-conductor, telephone) MATE/HUB port See the Operator’s Manual for more information on the RTS.
Installation AUX Wiring The AUX+ and AUX– terminals are a switched 12 Vdc supply. The AUX can respond to many criteria and control many functions. These include cooling fans, vent fans, load diversion, fault alarms, and automatic generator control. The AUX output can also be controlled externally through the system display. (For generator control, see the next page. For all other functions, see the system display manual and the International Series GFX Operator’s Manual.
Installation Automatic Generator Start (AGS) The AUX terminals can be used to perform “two-wire” generator start. A two-wire-start generator is the simplest type, where most of the circuits are automated. It usually has a single switch with two positions that is turned ON to start, OFF to stop. Either the system display or the FLEXnet DC can be programmed to perform automatic generator start using the AUX terminals. See the system display or FLEXnet manuals for programming instructions.
Installation A “three-wire-start” generator has two or more starting circuits. It usually has a separate switch or position for cranking the generator. The AUX terminals cannot control this type of generator without using a three-wire to two-wire conversion kit. Atkinson Electronics (http://atkinsonelectronics.com) makes these kits, among other companies. The Atkinson GSCM-Mini is designed to work with OutBack inverters and others. The drawing below is one example of a possible arrangement.
Installation Single-Inverter Installations When installing an inverter AC system, the following rules must be observed. All wiring and input breakers must be sized for 30 Aac or less. All output breakers must be sized appropriately for loads and inverter wattage.
Installation Multiple-Inverter Installations (Stacking) Installing multiple inverters in a single AC system allows larger loads than a single inverter can handle. This requires stacking. Stacking inverters does not refer to physically placing one on top of another. It refers to how they are wired within the system and then programmed to coordinate activity. Stacking allows all units to work together as a single system. Examples of stacking configurations include “parallel” and “three-phase” configurations.
Installation Parallel Stacking (Dual-Stack and Larger) In parallel stacking, two or more inverters are stacked to create a single, common 230 Vac bus. All inverters share a common input (AC source) and run loads on a common output. Up to ten inverters may be installed in a parallel arrangement. The example on this page shows three inverters. The wiring diagram on the next page shows four. 1.3 kVA 230 Vac Figure 20 1.3 kVA 230 Vac 3.9 kVA 230 Vac 1.
Installation Figure 21 900-0111-01-00 Rev A Parallel Wiring (Four Inverters) 29
Installation Three-Phase Stacking In three-phase stacking, inverters are stacked to create three separate 230 Vac output legs in a wye configuration. The output of each inverter is 120° out of phase from the others. Any two outputs produce 400 Vac between them. The outputs can be used to power three-phase loads when all inverters work together. Only three inverters, one per phase, may be installed in a three-phase arrangement. 1.3 kVA 230 Vac 1.3 kVA 230 Vac 1.3 kVA 230 Vac 1.3 kVA 230 Vac 1.

Installation Functional Test Once the mounting, wiring, and other installation steps are completed, proceed to the International Series GFX Operator’s Manual. The Operator’s Manual has steps for powering up and performing a functional test on the inverter system, as well as powering down and adding new devices to an existing system. Refer to the system display manual for programming instructions and menus.
