2. Enstalasyon ak Koneksyon Sistèm

Follow these steps for proper installation. Ensure all connections are secure and correct to prevent damage to the controller or other components. Always connect the battery first.

Figure 2: System Connection Diagram.

1. Connect Battery (1): Connect the battery to the charge controller first. Ensure correct polarity (+ to + and - to -). The controller will automatically detect 12V or 24V battery systems.
2. Connect Solar Panels (2): Connect the solar panel(s) to the charge controller. Again, observe correct polarity.
3. Connect DC Load (3 - Optional): Connect your DC loads (e.g., LED lights) to the controller's load terminals. Ensure correct polarity.
4. Connect Inverter (4 - Optional): If using an inverter for AC loads, connect it to the battery terminals. The inverter should not be connected directly to the load terminals of the controller.

Nòt enpòtan: Connect in strict accordance with the sequence: 1. Battery, 2. Solar Panel, 3. Load. Disassembly should be in the reverse order to prevent damage.

Montaj:

• Mount the controller on a vertical surface to allow for proper heat dissipation.
• Ensure adequate clearance around the controller for air circulation.
• Avoid mounting in direct sunlight, high temperatures, or areas prone to water exposure.

3. Operasyon ak Anviwònman

The controller features an LCD display and three buttons for navigation and parameter adjustment.

3.1. Entèfas ekspozisyon LCD

Figi 3: Ekran LCD ak Fonksyon Bouton yo.

• Bouton MENI: Short press to switch between display interfaces. Long press (3-5 seconds) to enter or exit parameter setting mode.
• UP bouton: In parameter setting mode, press once to increase the parameter value.
• Bouton DESANN/LIMEN/ETEN: In parameter setting mode, press once to decrease the parameter value. In normal display mode, press to turn the load on or off.

The LCD displays various information including voltage, ampere-hour, load output status, battery status, and solar panel charging light indicators (On: Direct/Boost Charge; Slowly Flash: Float Charge).

3.2. Paramèt Anviwònman

To adjust parameters, long press the MENI button for 3-5 seconds to enter the setting interface. Use the UP epi DESANN buttons to modify values. Long press the MENI button again to save and exit, or long press DESANN to restore default parameters.

Figure 4: Parameter Setting Flow.

The common adjustable parameters include:

• Flote Voltage: Vol latage at which the battery is maintained after full charge.
• Volim Rekoneksyon Egzeyattage: Vol latage at which the load will reconnect after low voltage dekoneksyon.
• Volim Sispansyon Egzeyattage: Vol latage at which the load will be disconnected to protect the battery from over-discharge.
• Mòd travay: Configures how the load operates (e.g., 24 hours, dusk to dawn, timed).
• Kalite batri: Select the battery type (e.g., B01 for GEL, B02 for Sealed, B03 for Flood). This controller is only applicable to lead-acid batteries (Open type, VRLA, GEL, etc.).

4. Antretyen

Antretyen regilye asire pèfòmans optimal ak lonjevite kontwolè chaj solè ou a.

• Lapwòpte: Kenbe kontwolè a pwòp epi san pousyè ak debri. Sèvi ak yon twal sèk pou netwaye.
• Koneksyon: Periodically check all wiring connections to ensure they are tight and free from corrosion. Loose connections can cause overheating and damage.
• Vantilasyon: Ensure that the ventilation openings are not blocked to allow for proper heat dissipation.
• Kondisyon anviwònman: Verify that the controller is operating within its specified temperature and humidity ranges.
• Sante batri: Kontwole sante ak volim batri ou atage regularly. A healthy battery is crucial for the overall system performance.

5. Troubleshooting and Safety Protections

The Thlevel solar charge controller is equipped with multiple safety features to protect itself and your solar power system. Understanding these protections can help in basic troubleshooting.

Figure 5: Built-in Security Protections.

• Pwoteksyon kout sikwi: Automatically disconnects if a short circuit is detected in the load or solar panel circuit. Check wiring for shorts.
• Pwoteksyon Surcharge: Disconnects the load if the current exceeds the rated capacity (20A). Reduce the load or use a higher-rated controller.
• Plis pase Pwoteksyon Kouran: Similar to overload, protects against excessive current flow.
• Pwoteksyon twòp chaj: Stops charging the battery once it reaches the set overcharge voltage, preventing damage.
• Anba-voltage Pwoteksyon: Disconnects the load when the battery voltage desann anba volim ki fikse atage threshold, protecting the battery from deep discharge.
• Sou-voltage Pwoteksyon: Protects the system from excessively high voltage entrées.
• Pwoteksyon polarite ranvèse: Protects the controller from damage if the battery or solar panel connections are reversed. However, always ensure correct polarity during installation.

Pwoblèm komen:

• Pa gen ekspozisyon/Pa gen kouran: Tcheke koneksyon batri yo epi asire w ke batri a gen ase chaj.
• Batri pa chaje: Verify solar panel connections, ensure panels are receiving sunlight, and check for any shading. Confirm battery type setting is correct.
• Chaj la pa fonksyone: Check load connections, ensure the load is within the controller's current limits, and verify the load work mode settings. The battery might be too low (under-voltage protection activated).

7. Enfòmasyon sou Sekirite

Please read and follow all safety instructions carefully before installation and operation.

• This controller is designed for 12V/24V lead-acid batteries only (GEL, Sealed, Flooded). Do not use with other battery types (e.g., Lithium-ion) unless explicitly stated by the manufacturer.
• Ensure all wiring is correctly polarized before connecting. Incorrect polarity can damage the controller and other components.
• Install the controller in a well-ventilated, dry, and cool environment, away from flammable materials and corrosive gases.
• Pa eseye demonte oswa repare kontwolè a tèt ou. Al jwenn pèsonèl kalifye pou sèvis.
• Keep children away from the solar power system components.
• Mete ekipman pwoteksyon pèsonèl (PPE) ki apwopriye tankou gan ak pwoteksyon pou je pandan enstalasyon an.
