2. Installation and System Connection

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.

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

چڑھنا:

• 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. آپریشن اور ترتیبات

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

3.1. LCD ڈسپلے انٹرفیس

Figure 3: LCD Display and Button Functions.

• مینو بٹن: Short press to switch between display interfaces. Long press (3-5 seconds) to enter or exit parameter setting mode.
• یو پی بٹن: In parameter setting mode, press once to increase the parameter value.
• ڈاؤن/آن/آف بٹن: 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. پیرامیٹر کی ترتیبات

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

Figure 4: Parameter Setting Flow.

The common adjustable parameters include:

• فلوٹ والیمtage: جلدtage at which the battery is maintained after full charge.
• ڈسچارج ری کنیکٹ والیومtage: جلدtage at which the load will reconnect after low voltage منقطع
• ڈسچارج اسٹاپ والیومtage: جلدtage at which the load will be disconnected to protect the battery from over-discharge.
• کام کا موڈ: Configures how the load operates (e.g., 24 hours, dusk to dawn, timed).
• بیٹری کی قسم: 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 دیکھ بھال

باقاعدگی سے دیکھ بھال آپ کے سولر چارج کنٹرولر کی بہترین کارکردگی اور لمبی عمر کو یقینی بناتی ہے۔

• صفائی: کنٹرولر کو صاف اور دھول اور ملبے سے پاک رکھیں۔ صفائی کے لیے خشک کپڑا استعمال کریں۔
• رابطے: Periodically check all wiring connections to ensure they are tight and free from corrosion. Loose connections can cause overheating and damage.
• وینٹیلیشن: اس بات کو یقینی بنائیں کہ گرمی کی مناسب کھپت کی اجازت دینے کے لیے وینٹیلیشن کے سوراخوں کو مسدود نہیں کیا گیا ہے۔
• ماحولیاتی حالات: Verify that the controller is operating within its specified temperature and humidity ranges.
• بیٹری کی صحت: اپنی بیٹری کی صحت اور والیوم کی نگرانی کریں۔tage 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.

• شارٹ سرکٹ تحفظ: Automatically disconnects if a short circuit is detected in the load or solar panel circuit. Check wiring for shorts.
• اوورلوڈ تحفظ: Disconnects the load if the current exceeds the rated capacity (20A). Reduce the load or use a higher-rated controller.
• موجودہ تحفظ سے زیادہ: Similar to overload, protects against excessive current flow.
• زیادہ چارج تحفظ: Stops charging the battery once it reaches the set overcharge voltage, preventing damage.
• زیر جلدtagای تحفظ: Disconnects the load when the battery voltage drops below the set under-voltage threshold, protecting the battery from deep discharge.
• زیادہ جلدtagای تحفظ: Protects the system from excessively high voltagای ان پٹ
• ریورس پولرائٹی پروٹیکشن: Protects the controller from damage if the battery or solar panel connections are reversed. However, always ensure correct polarity during installation.

عام مسائل:

• کوئی ڈسپلے/کوئی پاور نہیں: بیٹری کے کنکشن چیک کریں اور یقینی بنائیں کہ بیٹری کافی چارج ہے۔
• بیٹری چارج نہیں ہو رہی: Verify solar panel connections, ensure panels are receiving sunlight, and check for any shading. Confirm battery type setting is correct.
• لوڈ کام نہیں کر رہا: 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 تحفظ چالو)۔
