Model

Elevate your solar power system with our versatile PWM Solar Charge Controller, available in 10A, 20A, and 30A models. Designed for optimal battery health and system efficiency, this intelligent controller automatically detects 12V or 24V systems and supports three crucial battery types: Lead-Acid, Ternary Lithium, and Lithium Iron Phosphate.

Key Features & Benefits:

  • Smart Battery Compatibility: Our controller is engineered to safely charge and maintain three popular battery types:
    • Lead-Acid Batteries: Reliable and robust, ideal for a wide range of applications.
    • Ternary Lithium Batteries: High energy density for compact and powerful setups.
    • Lithium Iron Phosphate (LiFePO4) Batteries: Known for their long lifespan and safety, perfect for demanding off-grid needs. (See specifications for default and adjustable voltage parameters for each battery type.)
  • Automatic 12V/24V System Recognition: No manual switching required! The controller intelligently identifies your system voltage for hassle-free setup and operation.
  • Comprehensive Protection Measures: Your valuable solar system components are safeguarded with multiple built-in protections:
    • Overcurrent Protection: Prevents damage from excessive current flow.
    • Temperature Compensation: Adjusts charging based on ambient temperature for optimal battery life.
    • Reverse Polarity Protection: Protects against incorrect wiring of solar panels or batteries.
    • Overvoltage Protection: Guards against damaging voltage surges.
    • Short Circuit Protection: Automatically shuts down in case of a short circuit.
    • Undervoltage Protection: Prevents batteries from being over-discharged.
  • User-Friendly LCD Display & Controls: Easily monitor and adjust your system settings with the intuitive LCD screen and simple button interface. Browse through real-time data like battery voltage, charge/discharge status, and load working mode. You can also customize parameters like float voltage, discharge recovery, and cut-off voltages to perfectly match your setup.
  • Convenient USB Charging: Equipped with dual USB output ports (Max 5V/2A), you can directly charge your mobile devices, making it perfect for off-grid living or emergencies.
  • Robust & Efficient Design: Built for durability and reliable performance, this PWM (Pulse Width Modulation) controller efficiently manages power from your solar panels, maximizing energy harvest while protecting your batteries.

Ideal For:

  • Off-grid solar systems
  • RV and marine applications
  • Small home solar setups
  • Cabins and remote power solutions
  • DIY solar projects

Choose the amperage (10A, 20A, or 30A) that best suits your solar panel array and battery bank for a dependable and protected power solution.
