LiTime 12V/24V 20A PWM Solar Charge Controller with Bluetooth

  • Features advanced digital PWM control technology with optimized charging algorithms for commonly used battery types including LiFePO4, Lithium, Lead-Acid, SLA, and GEL.
  • Features built-in Bluetooth for wireless connection to mobile devices. Use the LiTime App to monitor and manage your solar system from your phone. 
  • The automatic detection function recognizes 12V or 24V battery systems, suitable for RVs, home small solar systems, trailers, and campers without manual configuration.
  • Supports up to 340W of maximum solar input for 12V systems. For 24V systems, support increases to 680W. 
  • Engineered with a heavy-duty sealed aluminum enclosure, this PWM solar charger delivers industry-leading IP68 water, dust resistance, and heat dissipation. 
  • Pre-installed cables feature watertight seals and strain relief for robust connections. Together with the all-metal housing, this ensures uninterrupted performance in even the harshest outdoor conditions.
  • Integrated multiple protection measures prevent damage to the controller from overcurrent, overvoltage and overheating, while also protecting the connected load.
  • A fast-acting circuit breaker cuts off output when excess current is detected, and automatically resumes normal operation after clearing the fault for reduced risk.
  • Over-temperature protection will shut down the controller and automatically restart it once the internal temperature cools down.

    FAQ

    Q: What is the main difference between MPPT and PWM charge controllers?

    A:

    The main difference is in how they regulate the charging process. MPPT controllers track the maximum power point of the solar array to extract the most power, while PWM controllers simply regulate the voltage to the battery. Can read on MPPT VS PWM for more information.

    Q: What are the advantages of using a PWM solar controller?

    A:

    PWM controllers are cost-effective, simple to use, and reliable. They are suitable for smaller solar power systems and are generally more affordable compared to MPPT (Maximum Power Point Tracking) controllers.

    Q: Can LiTime PWM solar controller be used with different types of batteries?

    A:

    Yes, LiTime PWM controllers are compatible with various types of batteries, including lead-acid, gel, and AGM (Absorbent Glass Mat) batteries. They are designed to adjust the charging parameters based on the connected battery type.
