OutBack Power Inverters are out of stock
Subscribe to updates – we'll let you know when OutBack Power Inverters are back in stock. Normally, we update products every 2 weeks.
Founded in 2001 by three engineers with a long history of developing technologies for renewable energy applications, OutBack's founders believed that the renewable energy industry was on the verge of unparalleled growth, driven by the emerging need for sustainable alternative sources of energy. OutBack Power, headquartered in Bellingham, Washington and is the leading designer and manufacturer of advanced power electronics for renewable energy, back-up power and mobile applications.
OutBack initially designed and manufactured integration hardware used by solar installers to house and protect power electronics installed in remote environments and harsh condition locations around the world. Soon the company launched an advanced line of rugged inverter products that delivered pure sinewave power for off-grid residential and commercial installations, ultimately expanding its offering to include off-grid inverters with battery backup, grid-tie inverters with battery backup, Maximum Power Point Tracking (MPPT) charge controllers, communications products and a complete line of OutBack EnergyCell batteries designed specifically for renewable energy applications.
Founded in 2001 to pioneer power conversion technologies considered de facto standards today, and with an emphasis on product performance and reliability, OutBack has established itself as the product of choice in harsh environmental conditions and applications where product reliability is paramount.
17 years later, we continue to lead the way with advanced off-grid and grid-interactive battery-based renewable energy systems, the fully UL 1741 SA listed Radian Series and FXR Series inverter/chargers and our SystemEdge packages that bundle the right combination of energy storage and power electronics, merging energy independence with smart home technology for a range of common applications.
Whether the application is village microgrids in Africa, rural electrification projects in Latin America, remote off-grid cabins in Alaska, or a suburban home in Southern California, OutBack Power Technologies has set the bar for delivering advanced power conversion electronics.
The Company is also a member of The Alpha Technologies -- a global alliance of companies that share a common philosophy: create world-class powering solutions for communication, commercial, industrial and renewable energy markets.
The outback FXR series grid hybrid inverter represents the evolution of OutBack's legendary FX series, offering enhanced capabilities for both off-grid and grid-tied applications. These pure sine wave inverter/chargers deliver seamless power conversion with advanced battery charging functionality compatible with modern lithium-ion technologies.
The outback VFXR off-grid inverter charger provides ventilated cooling for high-ambient temperature applications and increased generator charging throughput. These models excel in demanding environments where sustained high-power operation is essential.
The outback radian series battery backup systems offer legendary durability with incredible flexibility to handle various power scenarios. With dual AC inputs accommodating both grid and generator sources, Radian inverters provide comprehensive backup power solutions for residential and commercial applications.
The outback mobile marine inverter systems deliver distortion-free true sine wave AC power with intelligent battery charging for RV, marine, and mobile platforms. These compact units provide complete power conversion solutions regardless of your destination.
All OutBack inverters produce outback inverter pure sine wave output that looks and acts exactly like grid electricity, ensuring perfect compatibility with sensitive electronics, computers, and appliances. This clean power output eliminates the humming and interference common with modified sine wave inverters.
OutBack's outback battery charging advanced technology includes sophisticated multi-stage charging algorithms optimized for various battery types, from traditional lead-acid to cutting-edge lithium-ion systems. The intelligent charging system maximizes battery life while ensuring optimal performance.
The innovative outback grid-zero technology inverters enable precise power management, automatically balancing between stored energy, solar production, and utility power to minimize grid consumption. This smart technology maximizes energy independence while reducing electricity costs.
OutBack's outback power system modular architecture allows systems to grow with your needs. Multiple inverters can be stacked in parallel, series, or three-phase configurations, providing scalability from residential to commercial applications.
