  • Page 3: Important Safety Information

    • Read all of the instructions and cautions in the manual before beginning installation. • There are no user serviceable parts inside the MPPT20CC. Do not disassemble or attempt to repair the controller. • Disconnect the solar module and fuse/breakers near to battery before installing or adjusting the MPPT20CC.
  • Page 4: General Information

    The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults. In addition, the MPPT20CC controller has a RJ45 interface to allow communication with a meter for remote monitoring. The MPPT20CC has the following features: •...

    Step 2: Check for Clearance Place the MPPT20CC in the location where it will be mounted. Verify that there is sufficient room to run wires and that there is sufficient room above and below the controller for airflow.
  • Page 9 Step 2: Load Wiring The MPPT20CC load output can connect DC electronic devices of which the rated voltage is the same as the battery. MPPT20CC will provide battery the voltage to the loads. See Section 4.4 Setting Operation for more details about the load control.
  • Page 10 Verify that all power terminals are tightened. Step 6: Confirm Power-up When battery power is applied and the MPPT20CC powers up, the battery led indicator will be green. If the MPPT20CC does not power-up or battery status LEDs error exists, refer to Section 5 “Troubleshooting”...
  • Page 11: Operation

    MPPT20CC does not create current! Rest assured that the power into the charge controller is the same as the power out of the MPPT20CC. Since power is the product of voltage and current (Volts × Amps), the following is true*: •...
  • Page 12 The greater the difference between battery voltage and the Vmp of the module, the more energy is wasted. MPPT20CC MPPT technology will always operate at the Vmp resulting in less wasted energy compared to traditional controllers.
  • Page 13: Battery Charging Information

    Float Charge After the Boost voltage stage, MPPT20CC will reduce the battery voltage to float voltage set point. When the battery is fully recharged, there will be no more chemical reactions and all the charge current transforms into heat and gas at this point.

    Equalize WARNING: Risk of explosion! Equalizing flooded batteries can produce explosive gases, so a well-ventilated battery box is necessary. NOTE: Equipment damage! Equalization may increase battery voltage to a level damaging to sensitive DC loads. Ensure that all load allowable input voltages are greater than the equalizing charging set point voltage.
  • Page 15 Charging Indicator The green LED indicator will turn on whenever sunlight is available for battery charging. Under normal charging conditions, the green charging LED will stay on at all times. The charging LED indicator flashes when the battery reaches over- voltage.

    5. Protections, Troubleshooting and Maintenance 5.1 Protection PV Array Short Circuit If PV array short circuit occurs, clear it to resume normal operation. PV Overvoltage If PV Overvoltage occurs, the array will remain disconnected until the voltage falls safely below the maximum rating. PV Overcurrent If PV Overcurrent occurs, the array will be disconnected automatically.

    High Voltage Transients PV is protected against high voltage transients. In lightning prone areas, additional external suppression is recommended. 5.2 Troubleshooting Faults Possible reasons Troubleshooting Charging LED indicator off during PV array disconnection Check that PV and battery wire daytime when panels are in direct connections are correct and tight.
  • Page 22: Maintenance

    5.3 Maintenance The following inspections and maintenance tasks are recommended at least two times per year for best controller performance: • Check that the controller is securely mounted in a clean and dry environment. • Check that the airflow and ventilation around the controller is not blocked. Clear all dirt or fragments on the heat sink.
