4. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your solar charge controller. Follow these steps carefully:

4.1 Mounting the Controller and Inverter

Mount both the solar charge controller and the inverter securely on a wall or suitable surface. Ensure adequate space around the units for ventilation.

4.2 Installing Circuit Breakers

Install appropriate DC circuit breakers for the PV input, the controller's charging line to the battery, and the battery-to-inverter discharge line. The current rating of each breaker should match the maximum current of its respective line.

4.3 Wiring Connections

1. Connect the controller's PV port to the PV breaker.
2. Connect the controller's battery port to the battery-side breaker. Use proper 6AWG cables for battery connections.
3. Connect the inverter's positive and negative terminals to the 250A DC breaker.
4. Connect the other side of the 250A DC breaker to the battery terminals. Always match polarity (positive to positive, negative to negative).
5. From the inverter's AC output terminal, wire out to the loads you need. Ensure clear distinction between live, neutral, and ground wires.

4.4 Powering On the System

Once all wiring is complete and connections are secure with correct polarity, power on the system step by step:

1. Switch on the battery breaker connected to the controller first.
2. Next, switch on the PV breaker.
3. Finally, flip the inverter's rocker switch to power it on.

The load connected to the inverter's AC output should begin operating normally.

5. Operating Instructions

The controller features an LCD screen and function keys for monitoring and configuration. You can navigate through various settings to view system status and adjust parameters.

5.1 Setting Battery Parameters

The controller comes with pre-set charging parameters for Sealed, Gel, Flooded, and LI (LiFePO4 and Lithium-Ion) batteries. You can customize charging parameters (Absorption Voltage, Float Voltage, Low Voltage Cutoff, Load Timer) according to your specific battery requirements.

Important: The PV input must be disconnected before setting parameters. If the solar controller displays night mode, perform a reset by connecting only the battery to the controller and holding the last button for more than 5 seconds to restore factory settings.

6. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your solar charge controller:

• Keep the controller clean and free from dust and debris.
• Periodically check all wiring connections for tightness and corrosion.
• Ensure the ventilation fans are not obstructed and are operating correctly.
• Monitor the battery temperature, especially for lead-acid batteries, to prevent overheating.

7. Troubleshooting

This section provides solutions for common error codes displayed by the Temank MPPT Solar Charge Controller (Keeper & POW-M Series).

7.1 Keeper Series Error Codes (E-nN)

• E-n1 Over-discharging (E-11): Occurs when lead-acid battery voltage drops below 10.8V (12V system) or 21.6V (24V system).
  Solution: Turn off the load, charge the battery until its voltage exceeds 12.6V. The controller will then clear the error and resume normal operation.
• E-n2 Overvoltage (E-12): Occurs when a lead-acid battery's voltage exceeds 16V (12V system) or 32V (24V system).
  Solution: Disconnect the PV input and stop charging. Measure the battery voltage and inspect the battery casing for damage. Check if the battery temperature is too high; if so, let it cool naturally. Use an appropriate load to discharge the battery safely until the voltage drops below 16V or 32V. The controller will resume normal operation once the voltage is within the acceptable range.
• E-n3 Overload (E-13): Occurs when the load exceeds the maximum capacity supported by the system (e.g., Keeper-1240 with 24V battery supports up to 720W).
  Solution: Reduce the load to ensure the controller operates within its supported range.
• E-n4 Damage to Internal Components of Load Output Terminal: This fault may be caused by a short circuit at the load end or by connecting an inverter to the load terminals of the controller. Connecting high-power loads or an inverter can cause excessive current, damaging internal components.
  Solution: If an inverter needs to be connected, connect it directly to the positive and negative terminals of the battery and avoid connecting it to the controller's load output terminals. Ensure loads do not exceed the controller's rated discharge current.
• E-n5 Over-temperature (E-15): Occurs when the controller's temperature exceeds 88°C, and charging will stop.
  Solution: Ensure the ambient temperature around the controller is not too high and provide adequate ventilation. Once the temperature drops below 73°C, the controller will restart and resume normal operation.
• E-n6 PV Input Overvoltage: Occurs when the PV input voltage exceeds the controller's maximum open-circuit voltage (e.g., Keeper-1240: 100V).
  Solution: Reduce the number of PV modules or change the series-parallel configuration to lower the PV array voltage. Exceeding this voltage may damage the controller's PV circuit board.

7.2 POW-M Series Error Codes (#NN)

• #18 Low PV Input Voltage: Occurs when the PV input voltage is too low.
  Solution: The PV input voltage should be higher than the boost charging voltage of the connected battery plus 2V. For example, for a flooded lead-acid battery with a boost charge voltage of 14.6V, the PV array voltage should exceed 16.6V.
• #60 Over-Temperature: Occurs when the controller temperature exceeds 88°C, automatically stopping charging and discharging.
  Solution: The controller will resume normal operation once the temperature drops below 75°C. Ensure proper ventilation and ambient temperature.
• #63 Battery Overvoltage: Occurs when the battery voltage exceeds the boost charging voltage, causing the controller to stop charging.
  Solution: Measure the battery voltage and inspect the battery casing for damage. If the temperature is too high, let it cool naturally. Discharge the battery using an appropriate load until the voltage drops below the boost charging voltage. The controller will resume normal operation once the voltage is within the acceptable range.
• #65 Low Battery Voltage: Indicates low battery voltage, ceasing all load-bearing operations.
  Solution: Charge the battery to resolve the error. Once the battery voltage recovers to the MPPT tracking return voltage, the controller will clear the fault code.
• #71 PV Input Overvoltage: Occurs when the PV input voltage exceeds the controller's maximum open-circuit voltage (e.g., 100A model: 160V).
  Solution: Reduce the number of PV modules or change the series-parallel configuration to lower the PV array voltage. Exceeding this voltage may damage the controller's PV circuit board.
• #72 Over-discharge current error: Indicates excessive discharge current at the load terminal, exceeding the maximum output current limit. This may be caused by multiple high-current loads.
  Solution: Reduce the number of loads to lower the discharge current and clear the error code.
• #73 Over Charging Current: Occurs when the charging current exceeds the maximum limit, depending on the PV array configuration.
  Solution: Reduce the number of PV modules to lower the charging current.
