OutBack Power HUB4 System Communication Manager:
The HUB system communications manager is the backbone of your networked OutBack power conversion system. The OutBack HUB communicates stacking, load share and power save on/off signals. Interconnection cabling is standard Ethernet CAT5 with RJ45 modular jacks. Through the use of a HUB, your system is completely coordinated and managed by the Mate remote.

There are two HUB Communication Manager products:
- HUB 4, which has four component ports plus a MATE port
- HUB 10, which has ten component ports plus a MATE port
When the MATE is attached to the HUB 4, it can display and manage any combination of four FX Series Inverters/Chargers and OutBack Charge Controllers. The OutBack HUB 10 allows the MATE to control up to 10 OutBack products of any combination.
Note: The OutBack HUB communicates stacking phase, load share, and incremental startup and shut down information directly among the FX Series Inverter/Chargers. The HUB is powered by any FX or OutBack Charge Controller connected to it.
