2. Safety Instructions

Please observe the following safety precautions during installation and operation:

Ensure all wiring is correctly polarized and securely connected.
Do not disassemble or attempt to repair the controller yourself. Contact qualified personnel.
Install the controller in a well-ventilated area, away from flammable materials.
Use appropriate circuit breakers or fuses for all connections (PV, battery, load).
Wear protective eyewear when working with batteries.
The controller is designed for specific battery types and voltages. Verify compatibility before connection.

3. Installation and Setup

3.1 Mounting the Controller

Mount the charge controller vertically on a non-flammable surface, ensuring adequate clearance for ventilation. Avoid direct sunlight, high temperatures, and humid environments.

3.2 Wiring Connections

Follow the wiring sequence carefully to prevent damage to the controller or other components. Always connect the battery first, then the solar panels, and finally the DC load.

Connect the Battery: Connect the battery cables to the battery terminals on the controller. Ensure correct polarity (+ to + and - to -).
Connect the Solar Panels (PV): Connect the solar panel cables to the PV input terminals. Ensure correct polarity and that the open-circuit voltage (Voc) of the solar array does not exceed the controller's maximum PV input voltage.
Connect the DC Load: Connect the DC load cables to the load terminals. Ensure correct polarity.
Grounding: Connect the grounding terminal of the controller to earth ground.

The display shows real-time data such as PV voltage, battery voltage, charging current, load current, and system status. Use the buttons to navigate through menus and adjust parameters.

4.2 Load Control

The TIS series controllers include load control functions, allowing you to manage the power supply to your DC loads. This can include timer settings, manual on/off, or dusk-to-dawn operation, depending on the model and configuration.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your charge controller:

Check Connections: Periodically inspect all wiring connections for tightness and corrosion.
Clean the Controller: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
Ventilation: Ensure that the ventilation openings are not blocked to prevent overheating.
Battery Inspection: Regularly check battery terminals for corrosion and ensure proper electrolyte levels for flooded batteries.

6. Troubleshooting

The TIS series controllers are equipped with multiple protection features to ensure system safety and stability. If an issue occurs, the controller may display an error code or indicate a protection state.

Common Issues and Solutions:

No Display/Power: Check battery connections and voltage. Ensure the battery is charged.
No Charging: Verify solar panel connections, polarity, and ensure sufficient sunlight. Check for PV over-voltage or reverse polarity protection activation.
Load Not Working: Check load connections, ensure load is not overloaded, and verify load control settings.
Over-current/Short Circuit: Disconnect the load and check for short circuits in the wiring. Reduce load if necessary.
Over-temperature: Ensure adequate ventilation around the controller.

Refer to the specific model's detailed manual for a complete list of error codes and advanced troubleshooting steps.
