OutBack Power Systems is proud to introduce our latest innovation: FLEXware, the next evolution of balance-of-system components.



We listened to our integrating partners, installers in the field and system owners. We took their suggestions and improved our product, from knockouts and breaker locations to more shared parts for easier ordering and stocking.

FLEXware is better integrated, modular, and more spacious than any of our previous metal hardware. Components are more versatile, there’s more space for wiring, and the all-aluminum, powder-coated construction is highly corrosion resistant for an installation that looks great even longer.

Installers can satisfy a large variety of applications by using FLEXware with OutBack's Modular power electronics .



FLEXware 250 offers a solution for AC and DC disconnects in single inverter/charger installations when space and budget are primary concerns. FLEXware 500 supports up to two inverter/ chargers and two charge controllers in an attractive, versatile and code-compliant package when split-phase and/or higher power output is needed. FLEXware 1000 accommodates up to four inverter/ chargers and four charge controllers. Both FLEXware 500 and FLEXware 1000 provide locations for auto-transformers, multiple DC shunts and other items required in high power applications.




The new FLEXware MP mounting plate shows the true versatility of FLEXware with its compatibility on both FW500 and FW1000 systems. All of the FLEXware options and accessories have been redesigned and simplified, replacing multiple models with fewer, more universal solutions.

FLEXware offers more application versatility than ever before - from the simplest of back-up power systems to a large 36 kW village power systems with multiple power sources such as PV, wind, hydro and back-up generators. With OutBack Power System’s FLEXware you can really “FLEX your system.”




FLEXware 250

For applications with modest power requirements like cabins, remote communication sites and back-up power systems.

The FLEXware 250 accommodates all of the essential protective devices in the smallest possible space at the lowest installed cost. The FW250 enclosure is designed to mount on either, or both, ends of an OutBack FX inverter. Smaller systems can include both the DC disconnect and AC input / output breakers in the same enclosure mounted on just the DC end of the inverter. Systems with more AC and DC components should use two FW250 enclosures, one on each end of the inverter. The FW250 system does not require a FLEXware MP mounting plate or the optional DCA or ACA conduit adapters. The FW250 can also be used on multiple inverter systems when installation space is limited.

As with all of the FLEXware systems – order the necessary DC and AC breakers, AC input-output-bypass kits and all other additional components separately.


  •  

For single FX Inverter/Charger systems 

  • Mounts directly to the end of a FX Inverter/Charger 
  • Extremely compact design 
  • Can be wall or shelf mounted 
  • Can be used for DC or AC components or both 
  • Knock-out provided for connection to MX60 charge controller 
  • Breaker spaces for battery, PV array or PV GFP breakers 
  • Mounting locations for AC GFCI outlet and AC breakers 
  • Optional DC current shunt kit mounts on inverter chassis

FLEXware 500

For applications with medium power requirements such as homes, light commercial or back-up power systems.

The FLEXware 500 accommodates all of the essential protective devices in two easy-to-install enclosures. The FW500-AC and FX500-DC are both designed to allow mounting in either a horizontal or vertical orientation to allow easier installation in space limited locations. The FW500 system uses a single FLEXware MP mounting plate and one set of the optional DCA and ACA conduit adapters for each FX inverter installed.

As with all of the FLEXware systems – order the necessary DC and AC breakers, AC input-output-bypass kits and all other additional components separately.


  • For single or dual FX Inverter/Charger systems 
  • Accommodates one or two MX60 Charge Controllers and disconnects 
  • Designed for wall-mounting using the FLEXware MP mounting plate 
  • Very compact design with room for expansion 
  • Separate AC and DC enclosure models 
  • Optimized knock-out locations 
  • 500 amp shunt assembly included – space for two additional DC shunts included 
  • Ground bus bar included standard
  • Powder-coated aluminum with stainless steel hardware 

FLEXware MP is a one piece, powder coated aluminum mounting plate for FW500 and FW1000 systems. The FW-MP make installation quick and easy by including all of the necessary stainless steel hardware to mount both the AC and DC enclosures, inverter/chargers and breakers. A single FW-MP accommodates a complete FLEXware 500 system.



FLEXware 1000

For applications with large power requirements such as large residential, commercial or village power systems.

The FLEXware 1000 accommodates all of the required protective devices in two enclosures with room for additional breakers and large AC and DC cable connections. The FW1000-AC and FW1000-DC enclosures are both designed to allow mounting in either a horizontal or vertical orientation to provide more installation flexibility and easier wiring connections. The FW1000 system uses two FLEXware MP mounting plates and one set of the optional DCA and ACA conduit adapters for each FX inverter installed.

As with all of the FLEXware systems – order the necessary DC and AC breakers, AC input-output-bypass kits and all other additional components separately.


  • For single, dual, triple or quad FX Inverter/Charger systems
  • Accommodates up to four MX60 Charge Controllers and disconnects
  • Designed for wall-mounting using two FLEXware MP mounting plates
  • Compact design with room for expansion
  • Can be used as a building block for larger systems
  • Separate AC and DC enclosure models
  • Optimized knock-out locations
  • 1000 amp shunt assembly included

– space for two additional shunts included

  • Ground bus bar included standard
  • Powder-coated aluminum with stainless steel hardware

FLEXware MP is a one piece, powder coated aluminum mounting plate for FLEXware 500 and FLEXware 1000. The FW-MP make installation quick and easy by including all of the necessary stainless steel hardware to mount both the AC and DC enclosures, inverter/chargers and breakers. Two FW-MP are required for a complete FLEXware 1000 system.
