Outback Flexmax 60 – 12/24/36/48Volt 60Amp

The OutBack Flexmax60 Maximum Power Point Tracking (MPPT) charge controller enables your PV system to achieve its highest possible performance. Rated for up to 60 amps of DC output current, the OutBack MX60 can be used with battery systems from 12 to 60 vdc with PV open circuit voltage as high as 125 vdc. The MX60’s setpoints are fully adjustable to allow use with virtually any battery type, chemistry and charging profile.

The OutBack Flexmax60 allows you to use a higher output voltage PV array with a lower voltage battery – such as charging a 24 vdc battery with a 48 vdc PV array. This reduces wire size and power loss from the PV array to the battery/inverter location and can maximize the performance of your PV system. The OutBack MX60 comes standard with an easy to use and understand display of the PV system performance. The four line, 80 character, backlit LCD display is also used for programming and monitoring of the system operation.
The OutBack Flexmax60 can also be connected to the OutBack MATE system controller and display to allow monitoring of up to eight MX60 controllers from a distant location – up to 300 feet away. The MATE also includes an optoisolated RS232 port for connection to a PC computer for data logging and system monitoring. The performance of the MX60 can adjust to changing temperatures with the use of a remote temperature sensor or RTS. For the MX60 to function properly, the RTS is essential.

FLEXmax 80

The FLEXmax 80 is the latest innovation in Maximum Power Point Tracking (MPPT) charge controllers from OutBack Power Systems. The FLEXmax 80&rsquos innovative MPPT algorithm is bothcontinuous and active, increasing your renewable energy yield up to 30%. Thanks to enhanced
cooling, the FLEXmax 80 can operate at its full 80 amp maximum current rating in ambient temperatures as high as 40 deg C.

Included in the FLEXmax 80 are all of the features first developed by OutBack Power in the revolutionary MX60, such as support for a wide range of nominal battery voltages and the ability to step-down a high voltage solar array to recharge a low voltage battery. A built-in backlit display shows status information at the touch of a button. Enhanced network communications allow the FLEXmax 80 to be remotely programmed via the optional MATE system display and controller.

The new FLEXmax 80 is the only choice when you demand a high performance, efficient and customizable charge controller for your advanced power system.
