FLEXware Integration Enclosures & Hardware
FLEXware is a convenient, all-aluminium power system, offering simple installation of OutBack power electronics components.
Three versions of FLEXware are available:
FLEXware 250 for single "FX Series" Inverter/Charger installations along with the desired AC and DC disconnects
FLEXware 500 which supports up to two "FX Series" and two OutBack Series Charge Controllers, accommodating both split-phase and/or higher power output as needed
FLEXware 1000 accommodates up to four "FX Series" and four OutBack Series Charge Controllers
FLEXware 250
Designed for applications with moderate power requirements such as baches, homes, remote communication sites and back-up power systems, the FLEXware 250 accommodates all essential protective devices in the smallest possible space and at the lowest installed cost. With their extremely compact design and unique mounting features, one or two FLEXware 250 enclosures can be mounted on each end of a single FX Series Inverter/Charger.
The powder-coated aluminium FLEXware 250 enclosure provides spaces for battery, PV array or PV GFDI breakers and mounting locations for AC GFCI outlet, AC breakers and an Input-Output- Bypass Assembly. In keeping with FLEXware design concept, the FLEXware 250’s flexibility is evident in the generous number of knock-outs allowing the installation of conduit, cable glands, and other installation accessories.
Holds up to eight 1 to 80 Amp, one 175 or 250 Amp panel mount breaker and a GFCI AC outlet (not included).
Does not use the DCA or ACA for connection to an FX Series Inverter/Charger.

FLEXware PV Combiner
OutBack's FLEXware PV Combiner Series sets the new standard for PV balance-of-system hardware. Ideal for both small or large systems, the FLEXware PV8 and FLEXware PV12 accommodates the overcurrent protection requirements of your application. From 150VDC breakers for low voltage PV systems, to 600VDC fuse holders for high voltage PV systems, the FLEXware PV Combiner series handles it all.
Designed to survive in outdoor environments, the rainproof, UL type 3R powder coated aluminum chassis can be mounted on a wall, sloped roof or pole. The unique angled negative terminal bus bar design makes wiring fast and easy without the larger output conductors blocking access to the smaller input terminals. Dual output lug terminals are included for up to 2/0 AWG conductors. The tinted flame-retardant polycarbonate deadfront panel creates a clean appearance while preventing accidental contact with the live terminals and is easily removable during installation.
The FLEXware PV Combiner makes it easy to take your installation to the next level.
