IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

The OutBack FLEXware PV-8 and PV-12 Combiners are listed by ETL as PV Combiners under the follow-

ing standards:

• UL 67, 11th Edition

• UL 1741, First Edition

• CSA C22.2, No.29-M1989

These enclosures meet Type 3R rainproof requirements when mounted vertically or leaning back to 14 degrees (3/12 pitch).

This enclosure is rated for up to 150VDC circuit breakers and up to 600VDC fuses.

Grounding Instructions – Each enclosure should be connected to a grounded, permanent wiring

system. For most installations, the negative battery conductor should be bonded to the grounding

system at one (and only one) point in the DC system. All installations must comply with all national

and local codes and ordinances. System grounding as required by the National Electric Code, ANSI /NFPA 70-1996, or other appropriate codes is the responsibility of the system installer.

The equipment ground on FLEXware PV Combiner is marked with this symbol:

NOTE: Solar panels produce electrical current when light is present, even during overcast weather. Do not wire from the array to the PV-8 or the PV-12 Combiner. Complete all connections inside the combiner  rst and then connect at the array.

OutBack Power Systems’ FLEXware

FLEXware is a convenient system of all-aluminum, powder-coated modular enclosures with associated

mounting hardware and stainless steel fasteners for housing OutBack power components. Our

indoor-rated enclosures and mounting plates o er secure and centralized installations for various

combinations of FX Series Inverter/Chargers, OutBack Charge Controllers, the OutBack HUB, MATE, and

Auto-Transformer, as well as breakers, bus bars, and balance-of-system components.

General Wiring and Installation Instructions

• Remove any necessary knockouts before securing the combiner to its mounting surface.

• Mount the combiner, securing it appropriately.*

• Slide the circuit breakers or fuse holders onto the DIN rail and lock in place.

• Secure the box lugs to the Combiner Bus Bar.

• Install the Combiner Bus Bar and secure it to either the fuse holders or the circuit breakers.

• Connect all wires to the fuse holders or circuit breakers and the box lugs, securing them

according to the listed torque values.

• Connect the wires to the solar array.

*FLEXware PV-8 and PV-12 Combiners are designed for weather-resistant outdoor installation when appropriate fasteners and secure mounting surfaces are used. The back of each combiner has knockouts to accommodate fasteners, U-bolts, or other hardware for secure attachment to a solid surface, including pole mounting. Both the surface and the fastening hardware must be su cient to support the weight of the combiner.

Requirements

• Use minimum 75

• Use only code-approved, appropriately listed circuit breakers, fuse holders, and fuses.
