These are the best charge controllers on the market, they are solid, reliable and now an extreme version for outdoor use.
OutBack created the de facto industry standard when the company introduced its MX60 design, the first multi-voltage MPPT (Maximum Power Point Tracking) charge controllers. Now OutBack follows up on its original breakthrough with another first: a sealed, 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 links. 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.
The FLEXmax Extreme’s advanced thermal engineering provides full power output from -20 to 45°C without requiring a cooling fan. Because the passively cooled unit can be sealed, circuit boards and other sensitive electronics can be fully 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, increased wire-bending space, oversized terminals for easier installation with larger 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.
The FLEXmax Extreme Charge Controller can not only go anywhere, it can also get there faster by saving precious installation time. It is a fitting companion to OutBack’s renowned sealed FX inverter/charger line and demonstrates the company’s ongoing commitment to providing clean, reliable power anywhere it has the potential to transform lives.
