Features:

l   This is a mains complementary street light controller, using internationally renowned brand industrial-grade MCU full digital technology, ADC voltage and current   The collection is more accurate, the light on and off is consistent, and the anti-interference ability is strong. All resistive components adopt international first-line brands, and the output   The input and output electrolysis uses long-life solid capacitors to ensure that the hardware part has no aging and thermal drift problems, and the life is guaranteed. ；

l   High efficiency MPPT tracking technology, MPPT Tracking efficiency is up to 99%, system charging transfer The exchange efficiency is up to 95%; High efficiency MPPT tracking technology,   MPPT Tracking efficiency ≥99%, system charging conversion efficiency up to 98%;

l   led Boost conversion drive efficiency up to 97%, significantly reducing product temperature rise and also reducing battery discharge. ；

l   After the light is turned on, the battery is used first to discharge. When the battery voltage is lower than the set voltage value, it is seamlessly switched to the mains power supply for supplementary power supply.   Positive guarantee High brightness lights 365 days a year ；

l   4-digit DIP switch, 16 power adjustments, which can be dialed from 10W to 80W.   It is more convenient for customers to prepare goods ；

l   three-stage MPPT Charging management, constant voltage equalizing charging, constant current trickle charging and overcharging protection greatly extend the battery life ；

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 and the battery is   The pool will not be in deep overdischarge ；

l   Charging limit current 5-15 A Can be set to prevent users from damaging the lamps by mistakenly connecting the solar panels ；

l   Low voltage forces it into ultra-low power consumption mode, which saves energy for the battery under special circumstances and waits for the next charging time.   Always activate the system (For example, the solar panel is damaged, blocked by objects, etc.);

l   The lights are triggered by the mains power, allowing the lights to be turned on and off uniformly across the entire road section, with good consistency. ；

l   Prioritize the use of battery power. When the battery voltage is lower than a set value, directly and seamlessly switch to mains lighting mode (Notice:   It is only responsible for turning on the lights and does not charge the battery. );

l   Has the following complete protection functions:

 Battery anti-reverse connection protection (The battery must be connected first and then the photovoltaic plate );

 Solar photovoltaic panel anti-reverse connection protection (You must connect the battery first and then the battery solar panel );

 Photovoltaic panel output voltage over-voltage protection ；

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

 Battery overcharge and undervoltage protection ；

  LED Output open circuit protection ；

  LED Output short circuit protection (Supported by some models);
