The controller also features self-diagnostic capabilities to identify and highlight system errors. Common Questions What is MPPT technology and why is it important? MPPT (Maximum Power Point Tracking) technology allows the charge controller to find the optimal voltage and current point of your solar panels. This ensures maximum power extraction, leading to significantly higher energy yields (up to 30% more) compared to older PWM controllers, especially in varying weather conditions. Can this controller charge lithium batteries? Yes, the Photonic Universe TR3215BN is compatible with lithium batteries. You can select a dedicated lithium battery charging program or create a user-defined profile using the optional PC software or mobile app. What is the maximum solar panel voltage I can connect? This controller supports a maximum solar panel open-circuit voltage of 150V DC. This wide input range allows for greater flexibility in panel configuration, including connecting higher voltage panels or multiple panels in series. Do I need a remote meter or other accessories? While the controller operates automatically, optional accessories like the MT50 remote meter, Wi-Fi module, or PC connection cable enhance monitoring and control. These allow you to view real-time data, adjust settings, and customise charging parameters for your specific system needs. Installation Notes Always connect the battery to the charge controller first before connecting any solar panels. Ensure all power connections are tight to prevent excessive heating from loose contacts. Install appropriate external fuses or breakers for both the solar array and battery connections. Mount the controller indoors in a well-ventilated area, away from direct sunlight and moisture. The controller features negative common grounding, allowing negative connections to be earth grounded if required. Before You Buy Verify your battery system voltage (12V or 24V) matches the controller's auto-detection capability. Confirm your total solar panel power (Watts) does not exceed 390W for 12V systems or 780W for 24V systems. Check that your solar panel's open-circuit voltage (Voc) does not exceed 150V. Consider any optional accessories (remote meter, Wi-Fi module, PC cable) if advanced monitoring or customisation is desired. Ensure you have adequate wiring (up to 16mm²) and appropriate overcurrent protection for your system. Always verify product specifications and compatibility with your specific solar system components before purchase. This Photonic Universe controller is backed by a 2-year manufacturer warranty.
