    Please read all of the following instructions and the instructions that come with any other OutBack components that make up your power system. Further instructions on individual FX set-ups as well as systems assemblies are included with the FLEXware manuals.

  • Page 5: Safety Instructions

    • Passing inspection • Requiring a licensed electrician to do the work when mandated OutBack Power Systems cannot be responsible for system failure, damages, or injury resulting from improper installation of their products. Use only the recommended DC and AC wire sizes or greater. Be sure all wires are in good condition.
  • Page 6 WARNING: EXPLOSION HAZARD. WORKING NEAR LEAD ACID BATTERIES CAN BE DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. Design the battery enclosure to prevent accumulation and concentration of hydrogen gas in “pockets” at the top of the enclosure. Vent the battery compartment from the highest point to the outside. A sloped lid can also be used to direct the flow of hydrogen to the vent opening. CAUTION To reduce risk of injury, charge only deep-cycle lead acid, lead antimony, lead calcium, gel cell or absorbed glass mat type rechargeable batteries.

  • Page 7: System Protection

    All wired electrical systems require circuit breakers or fuses for protection. OutBack offers both breakers and fuses for over- current protection. If they are provided by other vendors, they must be properly rated.

  • Page 12: Mounting

    It is easier for two people to install the FX due to its weight. • OutBack FX inverters can be mounted in any position, but they perform better in locations offering plenty of air circulation. • Note: If using an OutBack FLEXware Mounting Plate, avoid large air gaps behind the plate which can result in louder mechanical noise during inverting/charging under heavy loads. • Due to the variance in other mounting methods, OutBack only endorses the use of FLEXware or...

  • Page 13: Wire Connections

    This breaker should be sized to protect the wire you are using, but should not exceed the maximum AC input current of the FX model used in the system (see FX product specifications, beginning on page 36). The breaker should be installed inside of a metal chassis such as OutBack’s FLEXware series or an existing panel.

  • Page 14: Torque Requirements

    • Use crimped and sealed copper ring terminal lugs with 0.79 cm (5/16”) hole or compression-type lug to connect battery cables to DC terminals. Soldered cable lugs are also acceptable. • Use recommended cable sizes (see page 42) to reduce losses and ensure high performance of FX (smaller cables can reduce performance and possibly damage the unit). • Keep cables together (e.g., using a tie-wrap) as much as possible. • Ensure cables pass through the same knockout and conduit fittings. This helps to cancel the effects of self-induction in the cables. TORQUE REQUIREMENTS CONNECTION TORQUE AC and PV breakers to 2.48 Nm/22 inch-lbs...

    You want to confirm the system is in good working order. Should you decide to install an OutBack MATE at a later date, bear in mind the installed switch overrides the control provided by the MATE if the switch is set to OFF. If the switch is set to ON, the MATE will function normally and control the inverter(s).

  • Page 27: Stacked Fx Systems

    • Three FX inverters can be stacked to supply three-phase power. This will provide the wattage of three units on a 230/400 Vac bus. • Parallel stacking requires the use of the OutBack HUB4. The HUB10 can be used if other devices need to be networked along with the inverters.

  • Page 28: Installation Types

    INSTALLATION TYPES SINGLE FX SYSTEM • All FX AC wiring must be sized to handle 30 amps AC or more. • A 30-amp input breaker must be used for all FX models. • A single FX can continuously power 2.0 kW to 3.0 kW of loads depending on which model is used. AC LOADS AC SOURCE...

  • Page 29: Parallel Dual Fx System

    PARALLEL DUAL FX SYSTEM • All AC wiring from the AC source and to the AC loads must collectively handle 60 amps AC or more. • All other AC wiring capacity must equal 30 amps AC. • A paralleled dual FX system can continuously power 4-6 kW of loads depending on which model is used. Note: Program the lowest-installed FX as Master (1-2ph MASteR) and the second FX as an out- Back L1 Slave (oB SLAVe L1).

  • Page 30: Parallel Quad Fx System

    PARALLEL QUAD FX SYSTEM • All AC wiring from the AC source and to the AC loads must collectively handle 100 amps AC or more. • All other AC wiring must handle a capacity of 30 amps AC. • This system can continuously power 8-12 kW of loads depending on which model is used. • Connecting more load than the continuous rating of the FX may cause breakers to trip or the FX to shut off its AC output.
  • Page 31 Parallel Quad System...

  • Page 32: 3-Phase System

    THREE-PHASE FX SYSTEM • This system produces 230 Vac per phase and 400 Vac from phase to phase. • All FX AC wiring must be sized to handle 30 amps AC or more. • This system can power continuously up to 9 kW of loads depending on which model is used. • Connecting more power than the continuous rating of the FX may cause breakers to trip or the FX to shut off its AC output. • The jumper in the HUB must be left in the standard position (usually called the “series/parallel” position) for three-phase configuration with International Series grid-tied models. (This instruction is specific for these FX models, and may conflict with the HUB Installation and User Guide.) Note: Program the bottom FX as Master and the two upper FXs as 3-phase Slaves (3p Classic B and 3p Classic C).

  • Page 36: Multiple Ac Sources

    MULTIPLE AC SOURCES WITH THE FX INVERTER When a system has the option of using either a generator or the utility grid as their AC input: • Both the AC “Hot” and AC “Neutral” lines must be connected to the appropriate source. • A connection can be made using a single-pole, double-throw switch (available from electrical component suppliers) which has one connection each for AC hot wire. • This switch must be rated to handle the system’s maximum AC voltage and AC current.
