• Kabellar: Use appropriately sized cables to minimize power loss and prevent overheating. Ensure proper fusing for all connections.

3.2. Simlarni ulash ketma-ketligi

The correct wiring order is essential. Always connect the battery first, then the solar panels, and finally the load (if applicable).

1. Connect the Battery to the Controller:

   First, connect the positive (+) terminal of the battery to the battery positive (+) terminal on the charge controller. Then, connect the negative (-) terminal of the battery to the battery negative (-) terminal on the charge controller. Ensure correct polarity. The controller's display should illuminate, indicating a successful battery connection.

2. Connect the Solar Panels to the Controller:

   Connect the positive (+) lead from your solar panel array to the PV positive (+) terminal on the charge controller. Then, connect the negative (-) lead from your solar panel array to the PV negative (-) terminal on the charge controller. Ensure the solar panels are receiving sufficient sunlight for power generation.
3. DC yukini ulang (ixtiyoriy):

   If you are using the DC load output, connect the positive (+) lead of your DC load to the load positive (+) terminal on the charge controller, and the negative (-) lead to the load negative (-) terminal. Refer to the operating section for load control settings.

O'chirish ketma-ketligi: To disconnect the system, reverse the order: first disconnect the load, then the solar panels, and finally the battery.
