Outback Solar Grid-Tie Inverter and Charger
OutBack FX and VFX inverters are modular "building block" sinewave inverter / charger that can be used for both residential and commercial off-grid and grid-tie applications with battery storage. Inverters are available in two versions; a sealed, fan-cooled FX version and a higher powered ventilated VFX version. Each inverter/charger module is a complete power conversion system - DC to AC inverter, battery charger and AC transfer switch. Additional inverter/chargers can be added at any time either in parallel (120VAC), series (120/240VAC), or even three-phase (120/208) configurations. This allows the system to be tailored to the specific needs of the application, both at the time of installation and into the future. With the addition of an X-240 autotransformer, multiple inverter systems can be set up to provide 120/240 VAC split-phase output with the ability to provide full power on either 120VAC leg of the system. Up to ten inverters can be connected together to provide up to 36 kW of continuous power capacity with the use of the HUB and the MATE controller.
The inverter's powerful battery charger operates in five stages: BULK (constant current output), ABSORB (constant voltage output), FLOAT (reduced voltage output), SILENT (no charger output) and EQUALIZE (constant voltage regulation overcharging). Charge time in each stage is adjustable to provide control and to maximize the performance ot the charger and battery system.
Each OutBack inverter has one programmable, auxiliary relay output connection (AUX). The AUX terminal provides 12VDC output to run 12V cooling or ventilation fans or operate an external relay to perform other functions, such as remote generator starting (two-wire), to disconnect external charging sources (such as solar panels), or to turn on a diversion load for voltage regulation.
The built-in transfer switch is rated for 60 amps. When an external source of external power (whether a generator or the utility grid) is detected at the "AC in" terminal on the inverter. The switch operates to rransfer the loads to the expernal power source and then activates the battery charger to recharge the battery bank.
Outback inverters come with a standard 2-year warranty and are listed to UL 1741.
