Product Features:
l Adopts internationally renowned brand industrial-grade MCU fully digital technology, ADC voltage and current acquisition is more precise, on/off light consistency is good, strong anti-interference capability. All resistors and capacitors use international first-tier brands, input and output electrolytics use long-life solid capacitors, ensuring no aging or thermal drift issues in the hardware, with guaranteed lifespan;
l High-efficiency MPPT tracking technology, MPPT tracking efficiency ≥99%, system charging conversion efficiency up to 98%;
l Three-stage MPPT charging management, constant voltage equalization charge, constant voltage float charge and overcharge protection, greatly extending battery service life;
l Five-stage discharge management, each period can control different output power, adaptive algorithm based on battery level( ABMS), truly ensuring 365 days of lighting guaranteed, low voltage automatically activates long-endurance lighting mode, ensuring longer lighting time, and the battery will not be in deep over-discharge;
l Charging limit current 5-30A can be set, avoiding damage to the lamp caused by user misconnection of solar panels;
l Low voltage forces entry into ultra-low power mode, saving energy for the battery under special circumstances, waiting for the next charge to
normally activate the system(e.g., solar panel damage, obstruction by objects, etc.);
l Light control function, high/medium/low adjustable, automatically turns on LED, at dusk, automatically turns off LED;
l Microwave induction, high/medium/low adjustable, induction time 10S-255S adjustable;
l Equipped with the following comprehensive protection functions:
Battery reverse connection protection (must connect battery first, then PV panel);
Solar PV panel reverse connection protection (must connect battery first, then solar panel);
PV panel output over-voltage protection;
Prevents battery from discharging to solar panel at night;
Battery overcharge and undervoltage protection;
LED output open circuit protection;
