5. Təhlükəsizlik Təlimatları
- 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.
- Install the controller in a well-ventilated area, away from direct sunlight, high temperatures, and moisture.
- Sistemin həcmini təmin edintage (12V or 24V) matches the battery bank voltage. The controller automatically detects this.
- Use appropriate wire gauges for all connections to prevent voltage düşmə və həddindən artıq istiləşmə.
- Batareyalar ilə işləyərkən göz qoruyucu vasitələrdən istifadə edin.
6. Quraşdırma (Quraşdırma)
Follow these steps for proper installation of your solar charge controller.
- Montaj: 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.
- Batareyanı birləşdirin: 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.
- Günəş panelini birləşdirin: 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.
- Connect the Load: 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.
Important Connection Order: 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.
