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’s performance. The four line, 80 character, backlit LCD display is also used for programming and monitoring of the system’s operation.
The OutBack MX60 can also be connected to the OutBack MATE system controller and display to allow monitoring of up to eight FX60 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.
Note: For optimal Maximum Power Point Tracking performance, it is recommended that MPPT charge controllers be used in conjunction with uniform solar arrays consisting of multiple, identical solar panels. MPPT charge controllers will still work with mixed arrays, but at reduced efficiencies, which defeats the whole point of MPPT technology. These devices were designed to calculate the most efficient charging characteristics given the assumption of a uniform array. Mixed arrays, by definition throw this calculation off.
Further, as it is designed for solar power, it can not be used with wind turbines. It is possible to use it with hydroelectric, although this is at the owner's own risk (ie. Neither the Alternative Energy Store nor Outback Power will be held responsible for any negative consequences associated with connecting it to hydropower). It needs to be programmed for the correct voltage so that the MPPT does not attempt to track the maximum power.
