  • 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.
