Charge Controller
MX60
e MX60 raises the bar for high performance solar controllers. OutBack’s ingenuity and
engineering experience has been combined to maximize the output power of your expensive
solar array. Our real time active Maximum Power Point Tracking (MPPT) system ensures that
your solar array is operating at its peak power point regardless of age, shading or environmental
conditions. Systems with large solar arrays are now a snap thanks to the MX60’s 60 amp
DC output current rating for 12, 24 or 48 VDC systems - all with just one product model!
Real wiring flexibility of your solar array is finally here because of the MX60’s wide range
DC input, up to 150 VOC. e ability to step-down a high voltage solar array to a low voltage
battery can save you money by reducing the size of wire required and making the installation
simpler and faster. Our smart multistage recharging process ensures your batteries are recharged
efficiently and gently to prolong battery life and achieves the highest possible performance.
All of the MX60’s status information is displayed on the large built-in 3.1" (8 cm) backlit LCD screen. Monitoring your
solar array’s performance is easy because of included data logging system that automatically records the last 64 days of
system operation. OutBack’s network communication system allows your MX60 to communicate with the rest of your
OutBack system, eliminating multiple product interaction problems and allowing remote monitoring via the OutBack
MATE display up to 1000 feet / 300 meters away.

Note * Add 1% to the solar arrays open circuit voltage for every 2.5° C expected below the 25° C standard panel rating (STC). The resulting value must be below 150 VDC at the
lowest expected temperatures conditions and less than 135 VDC for typical conditions to ensure reliable operation.
