With a HUB4, you can turn three separate Outback inverters into a 3-phase system. Or you could parallel four Outback 3kW inverters to give a 12kW inverter. 

The HUB system communications managers are the backbone of your networked OutBack power conversion system.  

The OutBack HUB communicates stacking, load share and power save off/on 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.
