3. Setup and Installation

3.1 Safety Precautions

  • Ensure all power sources are disconnected before installation.
  • Use appropriate tools and wear protective gear.
  • Verify correct polarity for all connections to prevent damage.
  • Install the controller in a well-ventilated area, away from direct sunlight and moisture.

3.2 Wiring Sequence

Follow the correct wiring sequence to ensure safe and proper operation:

  1. Connect the Battery: First, connect the battery to the controller's battery terminals. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the system voltage (12V or 24V).
  2. Connect the Solar Panel: Next, connect the solar panel array to the controller's PV terminals. Ensure correct polarity.
  3. Connect the DC Load: Finally, connect your DC loads to the controller's load terminals. Do not exceed the maximum rated current for the load output.

Warning: Connecting the solar panel before the battery, or connecting the load before the battery, may damage the controller.

3.3 Battery Type Selection

The controller supports various battery types. You can select the appropriate battery type (e.g., Lithium, Sealed, Flooded, Gel, AGM) through the controller's settings menu or via the Sunthysis Scontroller APP. Refer to the 'Operating Instructions' section for details on using the APP.
