Product Features:

l Integrates MPPT charging control, discharge management, and LED lamp beads into a single unit (referred to as M-COB), making the circuit simpler, production easier, and offering higher cost-effectiveness;

l Utilizes international renowned industrial-grade MCUs with full digital technology, ensuring more accurate ADC voltage and current collection, better continuity of light-on and light-off, stronger anti-interference ability, and the use of international leading brands for all resistive components, input and output electrolytes using long-life solid-state capacitors to ensure no aging or thermal drift issues in the hardware part, and guaranteed lifespan;

l High-efficiency MPPT tracking technology, with MPPT tracking efficiency ≥ 99%, and the system charging conversion efficiency reaching up to 98%;

l Three-stage MPPT charging management, including constant voltage equalization charging, constant voltage floating charging, and overcharge protection, significantly extending the service life of the battery;

l Five-stage discharge management, where each period can control the output power, and based on the adaptive algorithm (ABMS) according to the battery's charge level, truly ensuring 365 days of guaranteed lighting, automatically starting the long-range lighting mode when the battery voltage is low, ensuring a longer lighting duration, and the battery will not be in a deep over-discharge state;

l Allows setting the charging limit current from 5 to 30A to prevent users from mistakenly connecting the solar panel and damaging the lamp;

l Light control function, adjustable from high to low grades, automatically lights up the LED when it gets dark, and automatically turns off the LED when it gets bright;

l Microwave sensing, adjustable from high to low grades, with sensing time adjustable from 10 seconds to 255 seconds;

l Equipped with the following comprehensive protection functions:

Battery reverse connection protection (must connect the battery before the solar panel);

Solar panel reverse connection protection (must connect the battery before the solar panel);

Solar panel output voltage over-limit protection;

Preventing the battery from discharging to the solar panel at night;

Battery overcharge and under-voltage protection;

LED output open-circuit protection;

LED output short-circuit protection (supported in some models);
