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.Specification:Condition: 100% Brand NewItem Type: Solar Charge ControllerMaterial: Aluminum Model JN-MPPT-CL(50-120A) Current Rating (A) 50A, 60A, 80A, 100A, 120A (optional) System Identification Voltage Range (V) 12V System DC9V-DC16V 24V System DC18V-DC32V 48V System DC42V-DC60V Photovoltaic 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) MPP
