PV Logic 15A Dual Battery MPPT Pro Charge Controller Guide

The PV Logic 15A Dual Battery MPPT Pro Charge Controller is designed to maximize solar energy from 12V or 24V panels into a 12V battery. It uses MPPT technology to increase energy harvest by up to 20% compared to PWM controllers. The controller supports dual battery systems and includes Bluetooth for app connectivity.

Always disconnect the battery before working on electrical systems. Ensure all connections are secure to prevent short circuits. Use insulated tools and wear protective gear. Never connect the controller to a live battery or solar panel without proper setup.

Verify that your solar panels and batteries match the controller's voltage requirements (12V or 24V). Ensure the total current from the panels does not exceed the controller's 15A rating. Confirm the battery type (e.g., AGM, lead-acid) is compatible with the controller's charging logic.

Mount the controller in a dry, well-ventilated area. Connect the solar panels to the PV input terminals, then link the battery to the 'Battery 1' terminals first. Use appropriate wire sizes to minimize voltage drop. Follow the datasheet for specific wiring diagrams and polarity checks.

Pair the controller with your smartphone using the Bluetooth feature. The app provides real-time data on charging status, system performance, and alerts. Ensure the controller is in pairing mode and follow the app's instructions for successful connection.

After installation, test the system by exposing the solar panels to sunlight. Monitor the controller's display or app for charging progress and error messages. Check for loose connections and ensure the batteries are charging properly. Regularly review performance to optimize energy efficiency.
