- Боварӣ ҳосил кунед, ки система voltage (12V or 24V) matches the battery bank voltage. The controller automatically detects this.
- Use appropriate wire gauges for all connections to prevent voltagд афтодан ва аз ҳад зиёд гарм шудан.
- Wear eye protection when working with batteries.
6. Насбкунӣ (Танзим)
Follow these steps for proper installation of your solar charge controller.
- Монтаж: 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.
- Батареяро пайваст кунед: 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.
- Панели офтобиро пайваст кунед: 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.
- Борро пайваст кунед: 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.
