5. Kuiswa uye Setup

5.1 Chengetedzo Yekuchengetedza

• Ensure all wiring is done by qualified personnel.
• Usabvisa chifukidziro; hapana zvikamu zvinoshandisika mushandisi mukati.
• This equipment is designed for DC voltage to DC equipment.
• Always disconnect power sources before making or breaking connections.

5.2 Kuiswa

• Mount the controller vertically on a wall or other suitable surface.
• Ensure adequate air circulation around the controller for proper heat dissipation. Avoid mounting in enclosed spaces without ventilation.
• Keep the controller away from flammable materials, corrosive gases, and direct sunlight.

5.3 Kutevedzana kweWiring

Follow this sequence carefully to avoid damage to the controller or other components:

1. Batanidza Bhatiri: Connect the battery to the controller's battery terminals (BATT). Ensure correct polarity (positive to positive, negative to negative). The controller will detect the system voltage (12V or 24V) automatically.
2. Connect the Solar Panel (PV): Connect the solar panel array to the controller's PV terminals. Ensure correct polarity. The controller will begin charging the battery.
3. Connect the DC Load (Optional): Connect the DC load to the controller's load terminals. Ensure correct polarity.
4. Connect Communication Cable (Optional): If using the Modbus communication feature, connect the RS485 (RJ45) cable to the COM port.

WARNING: Never connect the solar panel array to the controller without a battery connected first. This can cause damage to the controller.

6. Operating Instructions

6.1 Yekutanga Simba-Kukwira

Once all connections are secure and correctly wired, the controller will power on automatically. Observe the indicator lights for proper operation. The controller will automatically detect the system voltage (12V/24V) and begin the MPPT charging process.

6.2 Sarudzo yeRudzi rweBhatiri

The Tracer3215BN supports various battery types: Sealed, Gel, Flooded, and User-programmable. Refer to the controller's display or accompanying software (if applicable) to select the appropriate battery type for optimal charging and battery longevity. Incorrect battery type settings can lead to undercharging or overcharging.

6.3 Maitiro Ebasa Rekurodha

The controller offers multiple load work modes to manage the DC output. These modes typically include:

• Manual Control: Turn the load on or off manually.
• Light Control: Load turns on at dusk and off at dawn.
• Light Control + Timer: Load turns on at dusk and stays on for a set duration.
• Dual-Time Control: Allows for two separate timer periods.
• Muedzo Wemamiriro: For system testing.

Consult the controller's interface or communication software for detailed instructions on configuring load work modes.

6.4 Real-time Energy Statistics

The controller provides real-time energy statistics, allowing users to monitor power generation from solar panels, battery charge/discharge status, and load consumption. This data can be accessed via the controller's display or through the Modbus communication interface with compatible software.

7. Kuchengeta

Regular maintenance ensures the longevity and optimal performance of your Tracer3215BN solar charge controller.

• Utsanana: Periodically clean the exterior of the controller with a dry cloth. Ensure ventilation openings are free from dust and debris.
• Connections: Annually check all wiring connections for tightness and corrosion. Loose connections can lead to power loss or overheating.
• Environment: Ensure the installation environment remains within the specified operating temperature range (-35°C to +55°C) and relative humidity (≤95% N.C.).
• Kuongorora: Visually inspect the controller for any signs of damage, such as cracks, discoloration, or unusual odors.
• Hapana Zvikamu Zvishandiswe Mushandisi: As stated in the safety warnings, the controller contains no user-serviceable parts. Do not attempt to open or repair the unit yourself. Refer servicing to qualified service personnel.

8. Kugadzirisa matambudziko

If you encounter issues with your Tracer3215BN controller, consider the following basic troubleshooting steps:

• Hapana Simba/Chiratidziro:
  • Check battery connections and ensure they are secure and have correct polarity.
  • Verify battery voltage is within the acceptable range (8-32V).
• No Charging from PV:
  • Ensure solar panel connections are secure and have correct polarity.
  • Check PV open circuit voltage and ensure it is within the controller's limits (Max. 150V).
  • Verify there is sufficient sunlight reaching the solar panels.
• Kutakura Kusina Kushanda:
  • Tarisa kubatana kwemutoro uye polarity.
  • Ensure the battery has sufficient charge. The controller will disconnect the load if battery voltage yakaderera.
  • Verify the selected load work mode is appropriate (e.g., not in "off" mode).
  • Check for overcurrent protection; if the load draws too much current, the controller may shut off the output.
• Unusual Behaviour:
  • Ensure the correct battery type is selected in the controller settings.
  • Check for any error codes or indicators on the controller's display.
