OutBack Inverter VFX3524 3500 Watts 24 Volts 120 VAC/60 Hz Ventilated Bug Proof Off Grid Inverter VFX Series The new OutBack VFX series is a ventilated version of the original sealed FX series modular "building block" sine wave inverter/charger that can be used for both small and large power systems. By allowing cooler outside airflow through the internal electronics, more AC power is available and operation in extremely hot environments is improved compared to the sealed FX series. Each OutBack FX or VFX inverter/charger is a complete power conversion system - DC to AC inverter, battery charger and AC transfer switch. Additional FX inverter/chargers can be connected at any time in either parallel (120 VAC), series (120/240 VAC), or three-phase (120Y208 VAC) configurations. This allows a system to be tailored to meet the specific power conversion requirements of the application, both at the time of the installation and in the future. The OutBack VFX series is also available in export versions with 230 VAC, 50 hz output that can be connected in parallel (230 VAC) or in three phase (230Y400 VAC) configurations. Like the FX series, the OutBack VFX is also designed to survive harsh environments around the world. The full sreened vent openings are "bug proof" and the die-cast aluminum chassis protects and keeps the power conversion components cool in very hot environments even when operated at high power for extended periods. The VFX can be used in high ambient applications up to 60° C (with reduced output ratings). The OutBack VFX series inverter/charger system is designed for both residential and commercial stand-alone or back-up power applications with battery energy storage. It is designed to operate as a coordinated system with the other OutBack products (i.e. the PSDC, PSAC and PSR enclosures as well as the MX60 MPPT charge controllers and MATE system controller and display). Up to eight VFX inverters can be connected together to provide up to 28,800 watts of continuous power conversion capacity. Extremely Rugged Built to survive dust, bugs, even rain and salt air. Ultra Clean AC Power Smooth, true sinewave AC output waveform - not a "34 to 52 step" sinewave approximation. Easy System Expansion Systems can grow with your needs - up to ten inverter/chargers can be stacked for up to 36,000 watts of continuous AC power. High Surge Power Proprietary current control system allows starting of larger motors than other inverter designs. Intelligent Battery Charger Advanced charging algorithms provide fast recharging while increasing battery life. Field Serviceable Both FX and VFX inverter/chargers can be upgraded or serviced - even in the field. Very Quiet The bugproof VFX inverters only have a variable speed thermostatically controlled fan. No more transformer buzz to annoy you. Networked Communications All of OutBack products can be connected together to form a network with monitoring and control via a single MATE display. Simple to Operate Everything works automatically. The system can be installed and programmed and then the MATE system controller can be removed for totally goof-proof operation. Capable Tech Support Help You can call or email and ask questions of the engineers that desgined your products. Tech support doesn't get any better than that.
