OutBack Inverter GTFX 2524 2500 Watt 24 Volt 120VAC 60Hz Sealed Grid-Tie Inverter (Turbo Included) The GTFX models incorporate a unique die-cast aluminum, sealed housing, which keeps the electronic components cool while protecting them from the major causes of inverter failure - corrosion, dust, insect and animal damage - even temporary submersion and pressure washing. All of the GTFX models also now include standard an external cooling fan to improve operation in high ambient temperature conditions and increased efficiency at high power. Grid Tie/Utility Interactive Capable Able to sell solar, wind or hydro power back to the utility grid. Reduce your utility bill by spinning your meter backwards! Provides Utility Back-Up Power Keeps your lights on when the power goes out as well as other loads like wells, TV, fridge, computer, garage door opener, alarm, etc. Works Automatically Built-in transfer switch automatically disconnects the house loads from the utility grid and powers them from the inverter during an outage. Safe and Approved Listed to UL1741 standards as a non-islanding power inverter system for renewable energy applications. Ultra Clean AC Power Smooth, pure sine wave AC output waveform-not a coarse stepped sine wave or modified square wave. Intelligent Battery Charger Advanced charging algorithms provide fast recharging while increasing battery life up to 10 years. Filed Serviceable Both FX and VFX inverter/chargers can be upgraded or serviced-even in the field. Networked Communications All OutBack products can be connected through a HUB to form a network with monitoring and control via a single MATE Display. Capable Tech Support Help You can call or email and ask questions of the engineers that designed your products. Tech support doesn't get any better than that. Features: ZERO watts of AC power draw at night - automatic "silent" sell mode built in. Daily energy production on par with battery-less grid-tie inverter systems. Modular configuration allows easy system expansion and flexible design with up to 10 inverters interconnected Integrated communication between the inverters and the charge controllers ensures proper operation Automatically optimizes the conversion efficiency by matching the number of inverters to the amount of power being sold or used.
