SKU SE-OP-IM-2 Categories ,


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.

When connecting the Outback MATE to more than one product, a HUB-4 or HUB-10 communication manager must be included in the system. The MATE can be located up to 1000 feet (300 meters) from the FX2024 or FX2548 inverter/charger systems using standard 8 conductor CAT5 type communication cabling with RJ45 modular 8 conductor jacks. This wiring is considered to be low voltage / limited energy circuits.

HUB-4 Communication Manager

The HUB-4 communication manager allows the MATE to control and monitor a maximum of four OutBack products. The inverter/chargers can be operated in a stacked or independent configuration, and OutBack MX60 PV MPPT charge controllers can also be used on any of the four available ports of the HUB-4. Future OutBack products will also be compatible with the HUB-4. The HUB-4 manages both the inter-inverter communications and the MATE-inverter communication. The HUB-4 also can be used with the X-240 autotransformer when series stacked to allow full surge and continuous AC load capacity of each FX to be available on either of the 120 VAC output circuits. When two or more FX inverters are stacked in a parallel or series configuration, the system automatically turns off any excess slave inverters to save power and maximize conversion efficiency. This power save system is fully automatic and works with or without the MATE connected to the system. One MATE system controller and display can be connected to the HUB. The maximum distance from the HUB-4 to the power conversion product should be under 10 feet. OutBack includes two three foot long CAT5 cables standard with the HUB-4. Check with your OutBack dealer for additional cables.
