5. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your solar controller. Please follow these steps carefully:

1. Choose a Suitable Location: Install the controller in a cool, dry, and well-ventilated area, away from direct sunlight, flammable materials, and moisture. Ensure there is sufficient space around the controller for air circulation, especially around the cooling fan.
2. Mounting: Securely mount the controller to a vertical surface using appropriate fasteners. Ensure it is stable and will not vibrate.
3. Wiring Sequence:
   • Connect Battery First: Connect the battery to the controller's battery terminals. Ensure correct polarity (positive to positive, negative to negative). The controller will power on and display battery voltage.
   • Connect Load (if applicable): Connect the DC load to the controller's load terminals. Ensure correct polarity.
   • Connect Solar Panel Last: Connect the solar panel array to the controller's PV terminals. Ensure correct polarity and that the PV open-circuit voltage does not exceed the maximum PV voltage (DC150V).

   Important: Always connect the battery first and disconnect the solar panel first when disassembling the system. Incorrect wiring sequence can damage the controller.

4. Connect Temperature Sensor: If included, connect the temperature sensor to the designated port. This helps the controller compensate for battery charging voltage based on ambient temperature.
5. Verify Connections: Double-check all connections for tightness and correct polarity before applying power.
