3. સેટઅપ અને ઇન્સ્ટોલેશન

Follow these steps for proper installation of your solar charge controller. Adhering to the correct connection sequence is crucial for system safety and functionality.

3.1. તૈયારી

• સૌર પેનલ: Ensure your solar panel's voltage and power output are compatible with the controller and battery system.
• બેટરી: Use a compatible battery type (e.g., AGM, Gel, Flooded, Lithium) for your 12V or 24V system.
• કેબલ્સ: Use appropriately sized cables to minimize power loss and prevent overheating. Ensure proper fusing for all connections.

3.2. Wiring Sequence

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. Connect the DC Load (Optional):

   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.

ડિસ્કનેક્શન ક્રમ: To disconnect the system, reverse the order: first disconnect the load, then the solar panels, and finally the battery.
