Common Questions What is MPPT technology and why is it beneficial? MPPT (Maximum Power Point Tracking) technology optimises the power output from your solar panels by continuously tracking their maximum power voltage point. This results in significantly higher efficiency (up to 30% more power) compared to traditional PWM controllers, especially in varying light conditions or when panel voltage is higher than battery voltage. Can I connect multiple solar panels to this controller? Yes, you can connect multiple solar panels in series or parallel, provided the total open-circuit voltage does not exceed 200V and the total power input remains within the controller's specified limits for your battery voltage (e.g., 4000W for a 48V system). Always consult the user manual for wiring diagrams and safety guidelines. Is this controller suitable for lithium batteries? The controller comes with pre-programmed charging parameters for Sealed, Gel, and Flooded lead-acid batteries. For lithium batteries, a user-defined battery type can be configured via the communication interfaces (remote meter, Wi-Fi module, or PC software) to match specific charging requirements. How do I monitor and adjust settings? The controller features a built-in LCD screen for basic monitoring. For advanced monitoring and parameter adjustment, you can connect an optional remote meter (MT50), a Wi-Fi module for a mobile app (Android/iOS), or an RJ45 to USB cable for PC software (Solar Station Monitor). Installation Notes Mount the controller indoors in a well-ventilated area, away from direct sunlight and moisture. Ensure at least 150mm clearance above and below the controller for adequate airflow and heat dissipation. Always connect the battery to the controller first before connecting solar panels to ensure proper system voltage recognition. Use appropriate external fuses/breakers as recommended in the user manual for safety. All wiring should be carried out by a qualified person following local electrical safety standards. Before You Buy Verify your total solar panel voltage (Voc) does not exceed 200V. Confirm your total solar panel power (Wp) is within the controller's limits for your battery voltage. Ensure your battery bank voltage (12V, 24V, 36V, or 48V) is compatible. Consider if additional communication accessories (remote meter, Wi-Fi module, PC cable) are needed for your setup. Review the detailed user manual for specific wiring and operational instructions. Always verify product specifications and compatibility with your existing system components before purchase. Installation should be performed by a qualified professional. This product is covered by a 1-year warranty.
