Common Questions

What type of batteries is this controller compatible with?

This Photonic Universe LUX1524WP-LI MPPT solar charge controller is specifically designed and optimised for 12V and 24V Lithium battery systems only.

Can I monitor or adjust settings remotely?

Yes, wireless monitoring and adjustment of settings are possible with the optional remote IR programmer, which is purchased separately.

What is the maximum solar panel wattage this controller can handle?

The controller can handle up to 200W of solar panels for a 12V system and up to 400W for a 24V system.

Is this controller suitable for marine environments?

Absolutely. With an IP67 waterproof rating and a fully sealed design, it is built to withstand heavy rain, splashes, and other challenging marine conditions.

Installation Notes

  • Ensure correct polarity when connecting solar panels and batteries to avoid damage.
  • Mount the controller in a well-ventilated area, even though it is sealed, to aid in heat dissipation.
  • Use appropriate cable gauges for your system's current to minimise voltage drop and ensure safety.
  • Refer to the included instruction manual for detailed wiring diagrams and operational guidance.
  • For optimal performance, keep the wire length between the battery and controller as short as possible.

Before You Buy

  • Verify your battery type is Lithium (LiFePO4 or similar) and matches 12V or 24V system voltage.
  • Confirm your total solar panel wattage does not exceed 200W (for 12V systems) or 400W (for 24V systems).
  • Check that your solar panel's open-circuit voltage (Voc) is within the controller's 55V maximum input limit.
  • Consider if you require the optional IR remote programmer for wireless monitoring and advanced settings adjustment.
  • Ensure you have the necessary tools and basic electrical knowledge for safe installation, or consult a qualified installer.
