  • Page 1 MX60 PV MPPT Charge Controller ’ ’ Please read this entire manual prior to installing and using the MX60 OutBack Power Systems, Inc 19009 62nd Ave NE Arlington WA 98223 360-435-6030 900-0028-2 REV 3.22 Serial #s 500 & greater...

  • Page 2: Important Safety Instructions

    Rated for up to 60 amps of DC output current, your MX60 can be used with battery systems from 12 to 60 vdc with PV open circuit voltage as high as 120 vdc. The MX60's setpoints are fully adjustable to allow use with virtually any battery type, chemistry and charging profile.

  • Page 3: Installation

    Under the wiring compartment cover are holes through the mounting feet for attachment to the CCB . There is also a mounting tab at the top of the MX60. When mounted to the OutBack CCB, the left side knockout will line up with knockouts in the PSDC.
  • Page 4 WIRE AND DISCONNECT SIZING When wiring the MX60 note that there is a current limit on the output at 60 amps and that the unit is listed to operate continuously at 60 amps. There is no 80% derating as required by the NEC for fuses, conductors, and most circuit breakers.

  • Page 5: Surge Protection

    In terms of NEC compliance and the 60-amp output rating on the MX60, the largest PV array that can be connected to the MX60 should have a rated short-circuit current of 48 amps. This will meet NEC requirements and allow the MX60 to perform maximum power-point tracking functions.

  • Page 6: Field Wiring Connections

    To the left of the PV+ terminal is an RJ45 jack marked MATE. The MATE is the OutBack remote display panel. Most of the status that is available on the MX60 is available at the Mate as well. Some triggered events will be able to be accomplished at the MATE also.

  • Page 7: Operational Status

    OPERATIONAL STATUS The MX60 Charge Controller has a 4 line, 80 character LCD display and four “soft key” buttons to allow the user to adjust battery charging parameters and access other information. The MX60 has a setpoint adjustment lockout that requires an access code to make any changes to the controller’s operation.
  • Page 8 The MX60 is in the Float charge stage and is keeping the battery at the Float voltage setpoint. If the system cannot keep up with the Float voltage setpoint, (eg. DC loads are on), then the MX60 will return to MPPTing and try it’s best at again reaching the Float setpoint target voltage.

  • Page 9: User Configuration

    Hit the button below “NEXT” to select the nominal battery voltage of your system, then press “ENTER”. The MX60 will ask “ARE YOU SURE?”. When you push the “YES” button, the unit will reset and then displays the Status Screen.

  • Page 10: Charger Parameters

    The time delay is adjustable from 0 - 250 seconds. Remote An OutBack MATE can control the operation of the Aux output of the MX controller. Only one MX or FX device's Aux control output can be automatically controlled by the MATE.

  • Page 11: Backlight Control

    The DC loads should be turned off and the battery should be charged enough so that the MX60 can reach the EQ setpoint voltage. NOTE: VALVE REGULATED LEAD ACID (VLRA) OR OTHER SEALED TYPE BATTERIES SHOULD NOT BE EQUALIZED...
  • Page 12 Figure 14 - Miscellaneous Screen 1 This is the open circuit voltage of the PV panels measured at the last wakeup cycle. State The MX60 has thousands of lines of code. Each operation is called a State. This number is useful for troubleshooting . PWM% This is the duty cycle of the buck converter.

  • Page 14 Voc quickly so it will come up and operate and not snooze at that point. The MX60 will abort the snooze cycle early if the Panel voltage goes a small amount above the last measured Voc.
  • Page 15 Park Mpp (% Voc): Picks the PV panel operating point voltage for U_pick MPPT mode and other conditions where the MX60 needs to run at a voltage that is a fixed percentage of the last measured Open Circuit Voltage. This is not normally a critical exact value. An MPP of 77 % of Voc is typically very close to the maximum power point of most panels.
  • Page 16 .5 volts, this setting is used to improve the accuracy of the MX60s battery voltage readings. This value is initially set at the factory for best accura- cy and is not changed when resetting the MX60 to another battery system volt- age.
  • Page 17 Low Cutoff Amps: Sets the battery chargers lowest current limit that the MX60 will allow to charge in MPPT mode before stopping and going back to sleep. If the battery charge current goes below this setting for a time, the MX60 will go back to sleep.
  • Page 18 Figure 24 - Max Absorb Time Max Absorb Time: (Maximum Absorb Time in hours) Sets the maximum amount of time the MX60 is allowed to stay in the Absorb charge stage. Adjustable from 1 to 4 hours. OPTIMIZATION Aux Polarity...
  • Page 19 MX60 float voltage above the voltage at which the inverter will be selling back. This ensures that the MX60 is always trying to put out more voltage than the inverter is trying to drag the battery voltage down to and to keep the current flowing. 0.5 Volts difference for 24V battery systems, or 1.0 volt difference for 48V battery systems is a good rule of thumb.
  • Page 20 Battery temperature compensation with other slopes: The MX60 uses a 5mV per degree C per cell (2V) Compensation slope required by UL if you run the MX60 at or near the default system voltages. If you need to use slopes other than this, you...
