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 at which solar panels produce maximum power. This significantly increases the efficiency of your solar system, especially in varying light conditions or when the solar panel voltage is higher than the battery voltage.
Can this controller be used with lithium batteries?
The controller is primarily designed for sealed, gel, and flooded lead-acid batteries. It also features a "User-Defined" battery type, which allows for customisation of charging parameters. Please consult your battery manufacturer's specifications and the controller's user manual to ensure compatibility and correct settings for any specific battery chemistry.
What does the remote LCD meter display?
The remote LCD meter provides real-time data on various charging parameters, including battery voltage, charging current (from solar and to load), battery state of charge, accumulated charge and discharge energy, and minimum/maximum voltages. It offers a convenient way to monitor your system without direct access to the controller.
Is professional installation required?
While the controller is designed for user-friendly setup, working with electrical systems and batteries can be hazardous. It is recommended that installation be carried out by a qualified professional or a competent person following all relevant safety standards and the detailed user manual.
Installation Notes
- Always connect the battery to the controller first before connecting solar panels.
- Ensure the controller is mounted indoors in a well-ventilated area, away from direct sunlight and moisture.
- Use appropriate cable sizes for solar panels, battery, and load connections to prevent overheating.
- Install external fuses/breakers as recommended in the user manual for added safety.
- Ensure all power connections are tight to avoid excessive heating from loose contacts.
Before You Buy
- Verify your battery system voltage (12V or 24V) matches the controller's auto-detection capability.
- Confirm your total solar panel power (W) and open-circuit voltage (Voc) are within the controller's limits (520W/1040W, 150V).
- Check the compatibility of your battery type with the controller's supported chemistries or user-defined settings.
- Consider the physical dimensions and IP rating (IP30) for your intended installation environment.
- Review the detailed user manual for comprehensive wiring diagrams and operational instructions.
Always verify product specifications and compatibility with your specific solar system components and consult the user manual for safe and correct installation. This product is supplied with a 2-year manufacturer's warranty.
