Low Light / Snoozing During the initial sweep (see Wakeup and Sweeping), if it is determined to be too late (or too early) in the day, the MX60 will display Low Light for a few seconds and then display Snoozing for 5 minutes (default). This reduces energy usage and unnecessary powering of the MX60. This message is also displayed in extremely cloudy weather. The Snoozing mode can be disabled and has two basic modes to choose from: one based on the speed of the PV to charge the input capacitors and the second looks at the initial wakeup sweep current to see if it reached the Low cutoff (default) current set point.

MX 2 Hot (Very rare) Either the MX60 is too hot or its internal temperature sensor is shorted. If this message appears, carefully check if the MX60’s heat sink is extremely hot. The heat generated by the MX60, and therefore its losses, is proportional to input voltage times output current. Avoid installing the MX60 in direct sunlight to help control its operating temperature.

New Voc The MX60 is acquiring a new open circuit panel voltage (Voc) periodically in the UPick MPPT mode or it found a new Voc during an initial sweep.

Re-Cal There are certain abnormal conditions that can confuse the current measuring method in the MX60. When and if one happens, the MX60 will temporarily stop and re-calibrate. This may happen because of negative current, i.e., current coming out of the input terminals instead of into the input terminals, or a tripped PV breaker. A new Voc is also acquired during a Re-Cal.

Sleeping The PV voltage is two volts less than the battery voltage. This may also appear during the day when the MX60 is transitioning between certain states, or due to other conditions.

Sweeping In Auto-Sweep MPPT mode, the MX60 is either (1) doing an initial sweep of the panel voltage from Voc towards battery voltage after wakeup, (2) doing a periodic mini-sweep to stay within its acquired Maximum Power Point voltage, or (3) sweeping to maintain the current limit. Below 5 amps of battery output current, “Sweeping” briefl y fl ashes on the display as the MX60 operates at the Park Mpp voltage.

SysError (Very rare) System Error indicates an internal non-volatile memory error. The unit will stop operating when this message is displayed. Call the factory if you see this message.

Unloaded The battery terminals abruptly unload. Unloaded is displayed if the battery breaker trips while MPPTing or the battery voltage is set too low.

MX60 specifications

The Outback Power Systems MX60 is a state-of-the-art solar charge controller designed for off-grid and grid-tied systems, providing users with cutting-edge technology and efficiency in managing their solar energy resources. This device stands out in the renewable energy market due to its versatile features, robust performance, and ease of use.

One of the main features of the MX60 is its high-efficiency MPPT (Maximum Power Point Tracking) technology. This advanced technology optimizes the energy harvested from solar panels by adjusting the electrical operating point of the modules, allowing the system to extract the maximum available power. The MX60 can handle a considerable input voltage of up to 150 volts and offers a maximum output current of 60 amps, making it suitable for both small and large-scale installations.

The MX60’s robust architecture ensures its durability in harsh environmental conditions. With an operating temperature range of -40°F to 176°F, the charge controller performs reliably in varied climatic conditions, whether in extreme heat or bitter cold. This makes it an ideal choice for remote locations and rugged terrains where traditional power sources might be unreliable or unavailable.

An intuitive LCD interface equipped with a user-friendly display allows for easy monitoring and configuration. Users can track real-time performance metrics, including solar array voltage, output current, battery voltage, and charging status. The device is also equipped with advanced programmable settings, offering users complete control over charging parameters and battery maintenance.

Moreover, the MX60 incorporates essential safety features, including over-voltage and over-current protection, reverse polarity protection, and temperature compensation. Such safety measures are crucial in preventing damages to both the controller and the connected battery system.

The MX60 is compatible with various battery types, including Flooded, AGM, Gel, and Lithium, providing flexibility in energy storage options. It seamlessly integrates with Outback's Radian inverter systems, facilitating a comprehensive energy management solution for residential and commercial applications.

In summary, the Outback Power Systems MX60 is an exceptional choice for those looking for a reliable and efficient solar charge controller. Its combination of advanced technology, robust construction, and user-friendly features makes it an essential component for anyone interested in harnessing the power of solar energy.
