Solar Charge Controller 12V 24V 10A PWM with Adjustable LCD Display Dual USB Ports Timer Setting Auto Parameter Battery Charging Overview This 12V 24V 10 amp solar charge controller uses PWM power control to manage charging, protect batteries, and regulate loads in small photovoltaic systems. It provides a clear adjustable LCD display, dual USB ports for device charging, and programmable timer functions. Automatic parameter detection simplifies setup and ensures appropriate charging behavior for common battery systems. Key benefits Reliable charge management: PWM control tracks solar output in real time to improve panel utilization and stabilize battery charging. Simple installation and setup: Auto parameter detection reduces manual configuration, while the adjustable LCD display makes status and settings easy to read. Multiple device charging: Dual USB ports allow convenient charging of phones, tablets, and other USB devices directly from the system. Flexible control: Builtin timer settings let you schedule load operation such as lighting without external timers. Compact solution for small off grid systems: Designed for 12V and 24V systems up to 10 amps, suitable for small arrays and battery banks. Features and specifications System voltage: selectable 12V or 24V automatic recognition Maximum charge current: 10 amps Charge control type: PWM technology with real time maximum power tracking Display: adjustable LCD showing voltage, current, battery status, and timer settings Outputs: dual USB ports for device charging plus load output with timer control Auto parameter charging: automatic detection and adjustment of charging parameters for proper battery charging PWM algorithm support: includes common tracking methods such as open circuit voltage algorithm, short circuit current algorithm, hill climbing algorithm, and perturbation observation method Function role: coordinates solar panels, batteries, and loads as the control core of a small PV system Performance notes PWM increases the effective output of photovoltaic panels by optimizing charge behavior and maintaining panels near their operating point. In practice PWM can significantly improve usable output. MPPT controllers may provide different gains under certain conditions, but this controller provides a cost effective, reliable approach for many small systems. Designed for steady performance in small installations where 10 amp current capacity is sufficient. Use scenarios Off grid lighting for a garden or pathway: use the timer function to schedule evening lights while the controller charges the battery during the day. Mobile applications such as RVs and small boats: power small loads and charge mobile devices via the dual USB ports while regulating battery charge from a roof mounted panel. Small cabin or workshop power: manage a modest panel and battery bank to supply lights, small electronics, and maintain battery health with automatic charging parameters.
