The OutBack Power Systems HUB-4 and HUB10 System Communications Manager allows the interconnection of up to ten OutBack power conversion devices with the OutBack MATE. The interconnection creates a completely integrated Power System that is coordinated and managed by the MATE.The OutBack HUB communicates stacking phase, load share, incremental start-up and shut down information directly between the inverters. Interconnection cabling is standard CAT5 eight wire with RJ45 modular jacks. The HUB is powered via any FX inverter/charger or MX60.
