Product overview This PWM solar charge controller, rated 60A, is designed for standalone solar energy systems and home applications. It combines multistage charging algorithms, automatic system voltage detection, and a backlit LCD to monitor and manage charging and discharging with selectable presets for common battery chemistries. Key benefits Simplifies system setup by automatically detecting system voltage among 12V, 24V, 36V, and 48V. Output voltage reported as 12V. Preset profiles for LiFePO4, Gel, and flooded leadacid batteries make configuration straightforward and reduce the need for manual tuning. Multistage charging and an adaptive boost mode help restore and maintain battery capacity over repeated cycles by monitoring battery response during initial charging. Builtin protections and automatic shutdown behaviors reduce the chance of damage from reverse polarity, short circuit, overdischarge, overcurrent, and excessive temperature. Realtime monitoring via a backlit LCD shows charging current, generated energy, battery voltage, temperature, and error codes, enabling quick setup and troubleshooting. Main features Current rating: 60A. Charging method: PWM (pulse width modulation) with multistage algorithm for regular recharge and maintenance cycles. Adaptive boost: evaluates battery response during initial charge to optimize recovery and full recharge. Automatic system voltage detection: identifies 12V, 24V, 36V, or 48V systems. Integrated battery presets: LiFePO4, Gel, and flooded leadacid options. Thermal control: charging halts automatically when internal temperature exceeds 85 degrees Celsius. Protections: reverse polarity protection, short circuit protection, overdischarge prevention, maximum charge current limiting, and load overcurrent detection. Silent operation with continuous temperature monitoring. Builtin backlit LCD for live parameter display and easy parameter setup and debugging. Selftest and electronic fault detection to reduce the risk of damage from incorrect installation or system faults. Performance and compatibility Suitable for offgrid solar systems and domestic energy storage applications. Work time: continuous 24 hours operation capability. Output voltage parameter provided as 12V. Compatible with common 12V battery types when presets are selected; supports higher system voltages through automatic detection. Typical use scenarios Home backup power: manage charging and battery maintenance for a small residential solar array and battery bank. Offgrid cabin or caravan: control charging and discharging of onboard batteries while monitoring system status on the LCD. Remote lighting and equipment: provide reliable charge control and protection for standalone solar installations powering lights, pumps, or monitoring devices. What it delivers This controller provides straightforward configuration, adaptive charging behavior, and comprehensive electronic protections to help maintain battery performance in standalone solar systems. The clear display and automatic detection features reduce setup time and make periodic checks and adjustments easier. Technical notes Color and model rating: 60A. Do not exceed the specified maximum charging current for your battery bank. Follow installation instructions and wiring polarity guidance; the controller includes selftest functions to detect common installation errors.
