The OutBack VFX 3524 is a modular "building block” sinewave inverter/charger and can be used for both small and large power systems. Each OutBack VFX 3524 inverter/charger is on its own complete power conversion system--DC to AC inverter, battery charger, and AC transfer switch.

Additional inverter/chargers can be connected at any time in parallel (120 VAC), series (120/240 VAC), or even three-phase (120/208VAC) configuration. This allows the system to easily be tailored to your specific power conversion needs. Inverters can be connected (i.e. stacked) at installation or afterwards if you need to expand your system.

The full-screened 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 OutBack VFX series inverter/charger system is designed for both residential and commercial stand-alone or backup power applications with battery energy storage. It is designed to operate as a coordinated system with the other OutBack products.

About Outback Power

Key Points:

  • Extended warranty, not offered by competitors
  • A trusted name in the renewable energy field, with a solid foundation in engineering
  • World-class customer service and technical support

Headquartered out of Arlington, Washington, OutBack Power was founded in 2001 by a small group of passionate engineers. The small startup quickly earned a reputable foundation by listening to their customers and incorporating many of the changes that were suggested, truly establishing a customer focused company. Today, they are a trusted name in the renewable energy field, offering a vast selection of innovative products that were exclusively pioneered by OutBack Power. Their product line includes off grid inverters, grid-tie inverters with battery backup, maximum power point tracking (MPPT) charge controllers, and communications/network products, along with a wide range of integration and safety hardware. Outpacing many of their competitors, OutBack Power offers an extended warranty option on many of their inverters.

OutBack Power is constantly expanding their industry leading level of customer service with dedicated, direct dial, tech support lines as well as an online "live-chat" service. As a distributor for OutBack Power products, Wholesale Solar is an integral part of the high level of support that customers have come to expect from OutBack Power.

OutBack Power is highly known for providing rugged inverters and charge controllers designed to survive in environments that would normally destroy other inverter/chargers. The FX series of sealed inverter/chargers comes with some of the most rugged features one can find on sealed systems. Some of these features include die-cast aluminum chassis with a powder-coated finish to prevent corrosion, generous use of gaskets and O-ring seals to keep water and small particles out, and a protective conformal coating on all circuit boards. The externally mounted "turbo" cooling system will keep your FX series inverter/charger running at peak performance in high heat conditions.

The FLEXnet ™ DC system has been leading the way in DC system monitoring devices. Integrated networked data from your system easily allows you to stay in constant touch with your system's level of performance and efficiency. The FLEXnet™ DC module seamlessly conforms to either the FW500-DC or the FW1000-DC enclosures, and can easily monitor up to three shunts.

OutBack Power also offers grid-interactive versions of their inverter/chargers, which come in either sealed (GTFX) or vented (GVFX) models, allowing you to sell solar, wind, and/or hydro power back to the utility grid. Utilizing a built-in 60A transfer switch, AC power is seamlessly switched between utility and battery power. For 120/240V power output configurations, the G series can easily be combined or "stacked". Back to Top
