The sealed, fan-cooled OutBack FX is designed to survive harsh environments. This inverter/charger 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 (120Y208 VAC) configurations, allowing 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 anX-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 of the charger and battery system.
Each OutBack inverter has a programmable, auxiliary relay output connection (AUX) that 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 PV), or to turn on a diversion load for voltage regulation.
The transfer switch is rated for 60 amps. When an external source of AC power (either a generator or the utility grid) is detected at the “AC in” terminal on the inverter, the switch operates to transfer the loads to the external power source, and then activates the
battery charger to re-charge the battery bank.
ETL Listed to UL 1741. Standard 2-year warranty with an available 5-year extended warranty.
The VFX2812M is identical to the VFX2812 except that it has a transfer switch that switches the hot and neutral for use in marine or RV applications.
