About This

Smart 3-Stage PWM Charging：Automatically detects 12V/24V batteries and optimizes charging with bulk-absorption-float stages, extending battery life for lead-acid/GEL systems. Built-in safeguards against overcurrent, short circuits, reverse polarity, and overcharging—ideal for DIY solar setups and backup power solutions.
LCD Real-Time Monitoring + Memory Function：Backlit screen displays solar input, battery voltage, and load status. Customize light/time control modes (e.g., dusk-to-dawn streetlights) with one-touch presets. Settings are retained even during power loss, eliminating repetitive configurations.
USB Quick Charge Ports：Power phones, tablets, or low-wattage devices via 5V/2.5A USB outputs while prioritizing solar energy for battery charging. Perfect for camping, sheds, or emergency power banks.
Flexible Model Options & Safe Installation：Choose from 10A, 20A, and 30A models to match your solar setup: the 10A version supports up to 120W (12V) or 240W (24V) solar panels, the 20A handles 240W (12V) or 480W (24V), while the 30A model manages 360W (12V) or 720W (24V) systems. Designed for indoor use (non-waterproof), ensure installation in dry areas and note that 24V systems require doubling input voltage values (e.g., 25V→50V).
Safe Uninstall Protocol & Warranty：Follow reverse order for disconnection (load→PV→battery) to prevent damage. Includes 12-month warranty + lifetime tech support. Note: Double voltage settings for 24V systems (e.g., 25V→50V input).
