Feature:1. Advanced multiple synchronous rectification technology, high conversion efficiency in low power charging environment, the system adopts universal negative circuit, making the system work more stable and reliable.2. Advanced MPPT maximum power point tracking technology, tracking efficiency is not less than 99.5%, compared with ordinary PWM algorithm, the efficiency is increased by 15% to 20%, using high‑quality components and advanced power conversion circuit, the maximum conversion efficiency can be 98 % above, the full load efficiency can be 97%.3. The structure is made of aluminum and can be used under various harsh conditions. The combination of multiple tracking algorithms can achieve fast tracking of the maximum power point.4. When the panel is partially blocked or a single block is damaged, the dual‑peak and multi‑peak tracking technology can accurately track the maximum power point, four‑stage charging method: MPPT balance charging‑supercharging‑floating charging.5. 12/24/48V automatic identification function, support data storage, storage time can be up to 10 years, in the current‑limiting charging mode, when the input power of the photovoltaic panel is too large and the charging current exceeds the rated current of the controller, the controller will limit the charging current to the rated current.6. With internal temperature detection function, when the controller temperature rises to 70°C, the controller will limit the charging current to half of the rated current, when the temperature reaches 90°C, the controller will turn off charging and output, thereby control the temperature rise of the controller.7. With battery temperature compensation function, it has a wide photovoltaic array operating voltage range (12V system, photovoltaic panel voltage up to 100V, 24V and 48V maximum voltage up to 150V). It has comprehensive protection functions such as overcharge, overdischarge, overtemperature, overload and reverse connection.Specification:Condition: 100% Brand NewItem Type: Solar Charge ControllerMaterial: AluminumModelJN-MPPT-CL(50-120A)Current Rating (A)50A, 60A, 80A, 100A, 120A (optional)System Identification Voltage Range (V)12V SystemDC9V-DC16V24V SystemDC18V-DC32V48V SystemDC42V-DC60VPhotovoltaic Panel Open Circuit Input Voltage Range (V)20V-100V (12V System)40V-150V (Recommend Below 145V) (24V System)80V-150V (Recommend Below 145V) (48V System)MPPT Efficiency>99.5%Conversion Efficiency>96%System Rated Voltage (V)12V System24V System48V System12V System Default ValueOver Voltage (Overcharge) (V)14-18V28-36V56-62VDefault 16VOver Voltage Return (V)13-17V26-34V52-62VDefault 15VCharging Limit Voltage (V)12.9-16.9V25.7-33.7V51.6-62VDefault 14.9VBalanced Charging Voltage (V)12.7-16.7V25.4-33.4V50.8-62VDefault 14.7VBoost Charging Voltage (V)12.4-16.4V24.8-32.8V49.6-62VDefault 14.4VBoost Charge Return Voltage (V)11.2-15.2V22.4-30.4V44.8-62VDefault 13.2VFloating Charge Voltage (V)11.8-15.8V23.6-31.6V47.2-62VDefault 13.8VOver Discharge Voltage (V)8.8-12.8V17.6-25.6V35.2-51.2VDefault 10.8VOver Discharge Return Voltage (V)11.1-15.1V22.2-30.2V44.4-60.4VDefault 13.1VBalanced Charging Time (H)1/2/3 HourDefault 2HBoost Charging Time (H)1/2/3 HourDefault 2HDevice Address1-99Default 6Light Control Turn-on Voltage (V)5-11VDefault 5Light Control Turn-off Voltage (V)5-11VDefault 6Light Control Delay (H)10 MinutesTemperature Compensation (℃)0-4Default 4Over Temperature Protection (℃)70℃ current reduction, 90℃ off charging and DC loadWorking Temperature (℃)-20℃-50℃Storage Temperature (℃)-40℃-80℃Humidity (%)10%-90%, no condensationWeight: Approx. 4545g / 160.3oz.Package List:1 x Solar Charge Controller5 x Screw2 x Hanging Board
