How to Install Xantrex Solar PWM 30A on Your Boat
Installing the Xantrex Solar PWM 30A Charge Controller for Boats & Marine Engines is straightforward but should be done with care. First, mount the controller in a dry, ventilated location near the battery bank. Ensure your solar panels and batteries are disconnected during the process to avoid damage or personal injury. Follow the labeled terminals: connect the battery first, followed by the solar panel and then the load if applicable.
Use appropriate gauge wires and marine-rated connectors to ensure long-lasting, corrosion-free performance. After the installation, turn on the system and observe the LCD display to confirm correct connections and charging status. Always refer to the installation manual for specific details and safety information.
