Applications
The International Series GFX inverters are intended for both 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 grid-interactive applications, the grid is the primary source of power to run the loads. When excess PV (or another renewable energy source) is available from the batteries, the inverter supports those loads with the PV. When the PV exceeds the load requirements, the inverter sells that excess power back through its input, to the utility grid. When the utility grid is not available, the inverter takes over to run the loads with PV and energy stored in the battery bank.
If the inverter is used as the primary source, the grid power will be used when the batteries have been drained. In this situation, the AC power, PV harvest, or other renewable energy can be used to recharge the battery bank.
In off-grid applications, the inverter can use the harvested energy from the battery bank as the primary power source. An AC generator can also be connected to support the system when required.
*Excess AC power not being used by the AC loads. Uses bidirectional AC input for sell-back. Requires a GFX Inverter/Charger programmed for a grid-interactive application. **AC power used for input onl
. GFX inverter should have its grid-interactive feature disabled when using a generator.
Figure 3 Applications (Example)
900-0111-01-00 Rev B 11
Planning
Renewable Energy
The inverter cannot connect directly to PV, wind turbines, 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. OutBack Power’s FLEXmax charge controllers can be used for this purpose, as can other products.
Battery Bank
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.
When planning a battery bank, consider the following:
¾
The GFX inverters work best with lead-chemistry batteries intended for deep discharge. These include batteries for marine, golf-cart, and forklift applications. They also include gel-cell batteries and absorbed glass-mat (AGM) batteries. OutBack Power recommends the use of batteries designed specifically for renewable energy applications. Automotive batteries are strongly discouraged and will have a short life if used in inverter applications. Nickel-based batteries are discouraged due to limitations in the GFX charger. Lithium-based batteries and other advanced battery technologies may require special considerations. Please contact OutBack Technical Support at technologies.
¾
These inverters are designed to work with 12-, 24-, or 48-volt battery banks, depending on inverter model. Before constructing a battery bank, check the inverter model and confirm nominal battery voltage.
¾
A vented enclosure for the battery bank may be required by electric code and is recommended in most cases for safety reasons.

before implementing advanced battery
CAUTION: Hazard to Equipment
Batteries can emit vapors which are corrosive over long periods of time. Installing the inverter in the battery compartment may cause corrosion which is not covered by the product warranty. (Sealed batteries may be an exception.)
Generator
The GFX inverters can work with any generator that delivers clean 230 Vac at 50 Hz. Inverters stacked for three-phase output can work with three-phase generators.
¾
The inverter/charger can provide a start signal to control an automatic-start generator. If automatic generator starting is required, the generator must be an electric-start model with automatic choke and two-wire start capability. For other configurations, additional equipment may be required.
¾
In all cases, the inverter may need to be programmed according to the specifications of the generator and the requirements of the system, using a remote system display. (See the International Series GFX Operator’s Manual and the system display manual.) Parameters to be programmed may include generator size, automatic starting requirements, and potential fluctuations in generator AC voltage.

Planning
Generator Sizing
A generator should be sized to provide enough power for all the loads and the battery charger.
¾
Available generator power may be limited by ratings for circuit breakers and/or generator connectors.
¾
The generator must be able to provide current to all inverters on a given phase or leg. Minimum generator wattage be able to maintain AC voltage or frequency for long periods of time if they are loaded more than 80% of rated capacity.

Installation
Location and Environmental Requirements
The International Series GFX inverters can be located outdoors, but OutBack recommends that they be protected from the environment.
¾
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.)
¾
For installations where the inverter may be exposed to water spray, the inverter must be mounted either with the base down (shelf mounting) or with the AC wiring compartment facing down (wall mounting). If mounted with the base down, water cannot be allowed to accumulate around the inverter’s base. There is a drainage system on the base of the inverter to dispel condensation. If submerged, water can enter this drain and cause failure.
¾
The inverter will perform more efficiently in locations offering plenty of air circulation. The recommended minimum clearance is 5 to 10 cm (2 to 4 inches) on all sides of the inverter.
¾
The inverter will function to all of its specifications if operated in a range of 0°C to 50°C (32°F to 122°F). Note that the inverter’s maximum wattage will derate in temperatures above 25°C.
¾
The inverter will function, but will not necessarily meet its specifications, if operated in a temperature range of –40°C to 60°C (–40°F to 140°F). This is also the allowable temperature range for storage. (The specifications are listed in the International Series GFX Operator’s Manual.)

Mounting
¾
It is easier for two people to install the GFX inverter due to its weight.
¾
The unit has four mounting holes, one in each corner. Use fasteners in all four corners for a secure installation.
¾
Due to the variance in other mounting methods, OutBack only endorses the use of FLEXware or previous versions of its mounting plate. Use M6 x 20 mm machine screws, one per corner, to attach the inverter to the mounting plate. Follow the instructions with each mounting system.
IMPORTANT:
Use correct fasteners to secure the GFX inverter to the mounting surface, regardless of the type of surface. OutBack cannot be responsible for damage to the product if it is attached with inadequate fasteners.
¾
Mount and secure each component before attaching any wiring.
¾
When the inverter is used with other metal housings, make sure that all housings are grounded appropriately. (See the grounding instructions on page 18.) Grounding other housings may involve metal-to-metal contact, or separate ground wires.
¾
If using an OutBack FLEXware Mounting Plate, avoid large air gaps behind the plate. These can result in louder mechanical noise during heavy inverting or charging. Mount the plate on a flat, solid mounting surface.

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

When installing DC cables:
¾
Make certain DC circuit breakers are turned to the off position, or fuses are removed, before proceeding.
¾
Note sizes in Table 4, but refer to applicable codes for absolute cable size recommendations.
¾
Battery positive and negative cables should be no longer than 3 meters (10 feet) each, to minimize voltage loss and other effects.
¾
Install all overcurrent devices on the positive cable.
¾
The cables listed above are for each inverter in a system. In a system with multiple inverters, each inverter requires its own cables and overcurrent devices of the size indicated.
¾
The inverter’s battery terminal is a threaded stud which accepts a ring terminal lug. Use crimped and sealed copper ring lugs with 0.79 cm (5/16 inch) holes, or use compression lugs.
¾
Tie, tape, or twist cables together to reduce self-inductance. Run positive and negative cables through the same knockouts and conduit.
If present, remove the battery terminal covers. These are made of stiff plastic with a snap-on design. Remove carefully using a flat screwdriver inserted into the slots on the sides of each cover.

AC Sources
The inverter’s transfer relay is normally set to provide inverter power to the output. When an AC source is connected and accepted, the internal transfer relay switches to transfer the AC source power to the loads. (See the Operator’s Manual for the inverter’s acceptance criteria.)

When a HUB occupies the inverter’s MATE/HUB port, the system display connects directly to the HUB. (If the system display is a MATE, do not connect it during initial startup. See the Operator’s Manual for more information.)
Inverters plug into ports 1 and above. Charge controllers and other devices plug into additional ports after the last inverter is connected. See Stacking on page 28 for information on connecting inverters. See the HUB manual for other devices.
he INVERTER ON/OFF jumper bridges two pins. This jumper (JP1) parallels the two INVERTER ON/OFF terminals on the Control Wiring Terminal Block. If either set of connections is closed, the inverter is ON. (Because the jumper is factory-installed, the inverter usually remains ON unless given a command by the system display.)
Removing the jumper will turn the

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.) The AUX output can only control one function at a time.
The terminals can supply up to 0.7 amps at 12 Vdc (8.4 watts). This is sufficient to drive a small fan, or a relay which can control a larger device. The terminals accept up to 2.5 mm (#14 AWG) wire.
The AUX circuit contains electronic overcurrent protection, which resets after being overloaded. No additional fuses are required for the AUX terminals.
In this example, the AUX directly drives a 12-volt vent fan. The + and – wires on the fan are connected to the AUX+ and AUX– terminals.
he AUX LED illuminates when the AUX output becomes active.

In this example, the AUX output drives a relay that diverts wind power. The relay’s coil is connected to the AUX+ and AUX– terminals. When the AUX output closes the relay (based on battery voltage), the relay diverts the excess wind power to a water heating element.

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.
Two-Wire-Start
The 12 Vdc signal provided by the AUX output can be switched on and off to provide a start signal. It is not usually recommended to connect the AUX terminals directly to the generator, but to use them to energize the coil of a 12 Vdc automotive or similar relay.
Depicted is the OutBack FLEXware Relay Assembly, which is sold for this purpose. The relay contacts can serve in place of the generator’s start switch. The battery shown below is depicted for clarity. In most cases, it is part of the generator’s internal starting circuit and is not an external component.
The drawing below is one example of a possible arrangement. Specific arrangements, relays, and other elements depend on the requirements of the installation and of the generator.

Three-Wire-Start
A “three-wire-start” generator has two or more starting circuits. It usually has a separate switch or position for cranking the generator. A three-wire generator has fewer automated functions than a two-wire. It usually requires multiple controls for starting, running, or stopping. The AUX terminals cannot control this type of generator without using a three-wire to two-wire conversion kit.

Multiple-Inverter AC 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.
Stacking Connections
Stacking requires an OutBack HUB product, as well as a system display, such as the OutBack MATE or MATE3. (If the MATE is used, it must have firmware revision 4.1.6 or above.) A system using four or fewer units may use the HUB4. Systems using up to ten units require the HUB10. All interconnections are made using CAT5 noncrossover cable.

Additional Ports P

Figure 19 OutBack HUB4, MATE3, and MATE
Each inverter must be assigned a status — “master” or “slave”. The master is the primary and most heavily used unit. The master inverter’s MATE/HUB port must connect to port 1 on the HUB.
Slave inverters provide assistance when the loads are more than the master can handle alone. Slaves plug into ports 2 and above on the HUB. In general, it does not matter which slave connects to which port. However, it is always important to keep track of units and ports for programming purposes. See the system display manual for more information.
Programming involves using the system display to assign a status and stacking value to the inverter on each port. Each inverter is assigned to power a specified phase of the system. These assignments can be changed at any time as long as the master is plugged into port 1.
IMPORTANT:
¾
The master inverter must always be connected to port 1 on the HUB. Connecting it elsewhere, or connecting a slave to port 1, will result in backfeed or output voltage errors which will shut the system down immediately.
¾
Installing multiple inverters without stacking them (or stacking them incorrectly) will result in similar errors and shutdown.
¾
Although stacking allows greater capacity, the loads, wiring, and overcurrent devices must still be sized appropriately. Overloading may cause circuit breakers to open or the inverters to shut down.

Parallel Stacking (Dual-Stack and Larger)
In parallel stacking, two or more inverters are stacked to create a single, common 230 Vac bus.
¾
All inverters share a common input (AC source) and run loads on a common output.

¾
All output circuit breakers must be sized appropriately for loads and inverter wattage.
¾
All inverters must be of the same model.
¾
The AC input (generator or utility grid) must be 230 Vac at 50 Hz (single-phase).
¾
When wiring the AC source to the inverters, local codes may require the inverter circuits to be located at the opposite end of the panel from the main circuit breaker. This prevents overloading of the AC bus.

¾
One slave inverter must be programmed as (See the system display manual for programming.)
¾
The inverters should be wired to the loads and to the AC sources in phase order. The master should be phase A, the first slave should be phase B, and the second slave should be phase C.
¾
All overcurrent devices must be sized for 30 Aac or less.
¾
All wiring must be sized for 30 Aac or more.
¾
All output circuit breakers must be sized appropriately for loads and inverter wattage.
¾
All inverters must be of the same model.
¾
The AC input (generator or utility grid) must be 230/400 Vac at 50 Hz (a three-phase wye configuration).
¾
When wiring the AC source to the inverters, local codes may require the inverter circuits to be located at the opposite end of the panel from the main circuit breaker. This prevents overloading of the AC bus.
IMPORTANT:
Although the HUB manual states that it is necessary to move the HUB’s jumper to the three-phase position, that statement is not applicable for this model. The jumper must be left in its original position.
