The controller also features smart self-diagnostics for easy troubleshooting. Common Questions What is MPPT technology? MPPT (Maximum Power Point Tracking) technology allows the charge controller to find the optimal voltage and current at which solar panels produce maximum power. This results in significantly more energy harvested compared to traditional PWM controllers, especially in varying weather conditions or when panel voltage is higher than battery voltage. Can I use this controller with lithium batteries? Yes, the Photonic Universe XTR2210N is fully compatible with LiFePO4 (lithium iron phosphate) batteries. It offers specific charging modes for lithium batteries, which can be selected via the LCD display, mobile app, or PC software. A "User-Defined" option is also available for custom settings. How do I monitor my solar system with this controller? The controller features built-in Bluetooth for wireless monitoring and parameter adjustment via a free mobile app. Additionally, it has an LCD display for real-time data and an RS485/RJ45 port for connection to an optional remote meter (MT52), Wi-Fi module, or PC software for more detailed insights and control. What wire size should I use for installation? The controller features three pairs of terminals (for solar panel, battery, and load) suitable for wires up to 16mm². Always ensure that the wire gauge selected is appropriate for the current and length of the run to minimise voltage drop and ensure safety. Installation Notes Always connect the battery to the charge controller first before connecting solar panels. Ensure correct polarity for all connections (solar, battery, load) to prevent damage. Mount the controller in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources. Use appropriate circuit breakers or fuses on both the solar panel and battery lines for safety. Refer to the detailed user manual for specific wiring diagrams and installation instructions. Before You Buy Verify your battery system voltage (12V or 24V) matches the controller's auto-detection range. Confirm your total solar panel power (in Watts) does not exceed the controller's maximum input (260W for 12V, 520W for 24V). Check that your solar panel's open-circuit voltage (Voc) does not exceed 100V. Consider your battery type and ensure it is compatible with the controller's pre-set or user-defined charging modes. Assess your load requirements; the controller supports a 20A discharge current for DC loads. Please verify all specifications and compatibility requirements with your existing solar system components before purchase. Product specifications are subject to change by the manufacturer.
