5. Xavfsizlik bo'yicha ko'rsatmalar

• Ensure all connections are tight and secure to prevent loose connections that can cause excessive heat.
• Always connect the battery to the charge controller first, then the solar panel, and finally the load. Disconnect in the reverse order.
• Do not connect an inverter directly to the load terminals of the charge controller. Connect inverters directly to the battery.
• Tekshirgichni to'g'ridan-to'g'ri quyosh nuri, yuqori harorat va namlikdan uzoqroq joyda, yaxshi gazlangan joyga o'rnating.
• Tizim jildga ishonch hosil qilingtage (12V or 24V) matches the battery bank voltage. The controller automatically detects this.
• Use appropriate wire gauges for all connections to prevent voltage tushish va qizib ketish.
• Batareyalar bilan ishlaganda ko'zoynakni himoya qiling.

6. O‘rnatish (Sozlash)

Quyosh zaryadini boshqarish moslamasini to'g'ri o'rnatish uchun quyidagi bosqichlarni bajaring.

1. O'rnatish: Choose a dry, well-ventilated location for mounting the controller. Ensure there is sufficient space around the controller for heat dissipation. Use the mounting holes provided on the unit.
2. Batareyani ulang: Connect the battery to the battery terminals on the charge controller. Ensure correct polarity (+ to + and - to -). The LCD display should illuminate, indicating the controller has detected the battery voltage.
3. Quyosh panelini ulang: Connect the solar panel to the solar panel terminals on the charge controller. Ensure correct polarity. The controller will begin charging the battery if sunlight is available.
4. Yukni ulash: Connect your DC loads (e.g., lights, fans) to the load terminals. Ensure correct polarity. The USB-A port can also be used for charging compatible devices.

Muhim ulanish tartibi: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load first, then solar panel, then battery.

6.1-rasm: A typical wiring diagram showing the connection of a 12V solar panel, the HQST PWM charge controller, a 12V deep cycle battery, and a 12V power inverter. Note the recommended fuse placement and wire gauges.

6.2-rasm: Visual step-by-step guide for connecting the HQST Solar Charge Controller: 1. Connect the battery. 2. Connect the solar panel. 3. Connect the load (light bulb). This sequence ensures safe and proper system setup.

7. Operatsiya

Once installed, the controller operates automatically. The LCD display provides real-time information about your system.

7.1 LCD displey va tugma vazifalari

The LCD cycles through various parameters such as battery voltage, charging current, load current, and temperature. The single red button is used to manually cycle through display modes or to enter settings for load control (e.g., timer settings for lights).

• Qisqa bosish: Cycles through display parameters.
• Long Press (approx. 5 seconds): Enters or exits setting mode for load control.

7.2 Yukni boshqarish

The controller offers programmable load control. You can set the load to turn on/off based on daylight or a timer. Refer to the specific settings menu on the LCD for detailed configuration. The USB-A port is typically powered when the load output is active.
