80A Solar Charge Controller with Dual USB and LCD Overview A compact 80A PWM solar charge controller designed for 12V and 24V systems with automatic voltage detection. Built from ABS with a large LCD, dual USB charging ports, adjustable charging parameters, and ultralow selfconsumption to extend battery life in offgrid setups. Key features and benefits Dual USB charging: Two 5V USB ports for direct charging of phones, tablets, and other USB devices without a separate power source. USB output up to 2A maximum. Efficient PWM regulation: PWM charging delivers stable, efficient control of charging and discharging. Adjustable parameters let you tailor boost, float, and recovery voltages to your battery type. Large LCD display: Clear readout of system current, temperature, light and delay control, and operating status for quick onsite monitoring and adjustments. Automatic 12V and 24V compatibility: Automatically adapts to 12V or 24V battery systems for flexible installation across different setups. Minimal battery draw: Ultralow selfconsumption helps preserve battery capacity when the system is idle, improving overall offgrid efficiency and longevity. Memory for power interruptions: Saves configured parameters so settings are retained after power failure or restart. Technical specifications Item type: Solar Charge Controller Size: 80A Material: ABS Weight: Approx. 185.00 g Color: Orange System voltage: 12V or 24V automatic adaptation USB output: Two USB ports, 5V 2A maximum Maximum PV input voltage: 12V system max 23V, 24V system max 46V Charging voltages and thresholds (default, adjustable) 12V system Boost charging voltage: 14.4V Float charging voltage: 13.7V Discharge stop voltage: 10.7V Discharge recovery voltage: 12.6V Charging recovery voltage: 13V 24V system Boost charging voltage: 28.8V Float charging voltage: 27.4V Discharge stop voltage: 21.4V Discharge recovery voltage: 25.2V Charging recovery voltage: 26V What this solves Eliminates the need for a separate USB power source by providing direct device charging from the controller. Prevents battery overcharge and deep discharge with adjustable boost, float, and cutoff voltages. Makes system monitoring and adjustments simple with a readable LCD and menu navigation. Saves battery capacity when idle through ultralow standby consumption. Typical applications RV and caravan power systems for charging house batteries and powering mobile devices while traveling. Offgrid cabin or camping setups to manage solar input, protect batteries, and charge small electronics. Small remote installations such as garden lighting or security cameras where reliable solar regulation and occasional USB charging are required. Package contents 1 x Solar Charge Controller Basic operation Use the front panel menu buttons to cycle through display screens and access adjustable parameters. Configure boost, float, and cutoff voltages to match the connected battery type. The controller retains settings after power loss. Compatibility and installation notes Designed for use with 12V or 24V lead acid battery systems. Verify battery type and set appropriate charging parameters. Observe the maximum PV input voltage limits: 23V for 12V systems and 46V for 24V systems to avoid damage. This 80A solar charge controller combines flexible system compatibility, direct USB charging, and clear system monitoring to simplify and protect small to medium offgrid solar installations.
