Features:
l Will MPPT charge control, discharge management and led Lamp beads, integrated (referred to as M- COB ), the circuit is simpler and the production is faster More convenient and more cost-effective ；
l Adopt internationally renowned brand industrial grade MCU Fully digital technology, ADC The voltage and current collection is more accurate, and the lights on and off are more consistent. Good, strong anti-interference ability, all resistive components adopt international first-line brands, input and output electrolysis uses long-life solid capacitors, ensuring Ensure that the hardware part is free from aging and thermal drift problems, and its lifespan is guaranteed ；
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 equalizing charging, Constant voltage float charge and overcharge protection protection, greatly extending the battery life ；
l Five-stage discharge management, each period can control the output of different power, adaptive algorithm based on battery power ( ABMS ), really do it The lights are guaranteed 365 days a year, and low voltage automatically activates the long-life lighting mode to ensure that the lighting time is longer Longer lasting and electric The pool will not be in deep overdischarge ；
l Charging limit current 5-30 A Can be set to prevent users from damaging the lamps by mistakenly connecting the solar panels ；
l Light control function, adjustable between high, medium and low settings, automatically lights up after dark LED, Automatically turn off at dawn LED;
l Microwave induction, adjustable high, medium and low range, induction time 10 S-255S Adjustable ；
l Has the following complete protection functions:
Battery anti-reverse connection protection (the battery must be connected first and then the photovoltaic panel);
Solar photovoltaic panel anti-reverse connection protection (the battery must be connected first and then the solar panel);
Photovoltaic panel output voltage over-voltage protection ；
Prevent the battery from discharging to the solar panel at night ；
