FLEXmax Extreme Charge Controller Environmentally-rated enclosure: • IP54 design for international markets • NEMA 3R for North American market Solid-state, passively cooled design enables sealed architecture, long-term reliability, and quiet operation Remote battery voltage sense improves battery charging performance and voltage measurement accuracy Powerful simplified fault sense supports today’s and tomorrow’s safety requirements Easily integrated AXS Card Modbus/TCP interface provides powerful command, control and integration for industrial customers Certifications include: UL1741, IEC 50178, IEC 61000-6-1, IEC 61000-6-3, RoHS, CE OutBack created the de facto industry standard when the company introduced its FLEXmax 60 design, the first multi-voltage Maximum Power Point Tracking (MPPT) charge controller. Now OutBack follows up on its original breakthrough with another first: an outdoor-rated charge controller with unprecedented thermal management capabilities designed for the most extreme environmental conditions. The FLEXmax Extreme is engineered around the concept that the strongest chain is one with no weak link. In the case of charge controller design, the weak link is typically the cooling fan. Removing the fan removes the greatest obstacle to long service life and high reliability, as fan problems severely limit power output. FLEXmax Extreme’s advanced thermal engineering provides full power output from -20 to 40°C without requiring a cooling fan. And because a passively cooled unit can be sealed, circuit boards and other sensitive electronics are protected from dust, dirt, insects, and other external sources of contamination. Installer features of the FLEXmax Extreme include: “ground- agnostic” design to support negative-, positive- and floating-ground systems, substantial wire-bending space, oversized terminals for easy installation with large gauge wire, and mechanical design that permits servicing and replacing all power components while the unit is mounted on a wall and attached to conduit. Because it is engineered for maximum performance in extreme and remote environments, the FLEXmax Extreme makes it easier than ever to use renewable energy sources to power remote installations-especially when integrated into system solutions with sealed inverter/ chargers and maintenance-free AGM batteries such as OutBack’s acclaimed FX series inverters and EnergyCell battery line. In any commercial or residential installation, the FLEXmax Extreme combines superior performance and efficiency with easier installation and OutBack reserves the right to make changes to the products and information contained in this document without notice.
