Built-In Protection Functions The Photonic Universe 60A PWM controller incorporates a full suite of electronic protection features to safeguard your solar system and batteries. These include protection against reverse current at night, automatic cut-off for over-charging and deep discharge, overheating, overload, short circuit, and reverse polarity for both solar panels and batteries. Common Questions What is PWM technology? PWM (Pulse Width Modulation) technology regulates the charging current by rapidly switching the solar array connection to the battery. This method helps to maintain the battery in a fully charged state, increase charge acceptance, and can extend battery lifespan. Can I connect a load directly to this controller? Yes, this controller features an optional 12V load output. This is particularly useful for connecting small DC loads such as lighting or fans, and it offers programmable settings for night-time applications. What battery types are compatible? The controller is designed for use with sealed (default), gel, and flooded lead-acid batteries. It allows for easy selection of the battery type to ensure appropriate charging parameters. Is a remote temperature sensor necessary? The controller has a built-in temperature sensor. However, it also includes terminals for an optional remote temperature sensor (sold separately). Connecting a remote sensor directly to the battery can provide more precise temperature readings, optimising the charging process, especially in environments with fluctuating ambient temperatures. Installation Notes Always connect the battery to the controller first to allow it to recognise the system voltage. Connect solar panels after the battery connection is established. Ensure correct polarity for all connections (+ to + and - to -). Install the controller in a well-ventilated area to ensure adequate heat dissipation. This controller features a positive common ground design. Refer to the detailed user manual for comprehensive wiring diagrams and operational instructions. Before You Buy Verify your battery bank voltage (12V, 24V, 36V, or 48V) matches the controller's auto-detection capability. Confirm your total solar panel power does not exceed the controller's maximum input capacity for your system voltage. Ensure your solar panel array's open-circuit voltage (Voc) does not exceed 96V. Choose the correct battery type (Sealed, Gel, or Flooded) in the controller settings for optimal charging. Consider if a remote temperature sensor is beneficial for your specific installation environment. Always verify product specifications and compatibility with your existing solar system components before purchase. This product is covered by a 1-year manufacturer warranty.
