1. Advanced MPPT maximum power point tracking technology, tracking efficiency is not less than 99.5%, compared with ordinary PWM algorithm, its efficiency is increased by 15%‑20%.
2. JN‑MPPT series products adopt the latest technology for research and development, and can realize multiple devices in parallel through RS485 communication interface.
3. With 12/24/48V automatic identification function, with overcharge protection, overdischarge protection, overheat protection, overload protection and reverse connection protection functions.
4. In the current limiting charging mode, when the input power of the photovoltaic panel is too large, the charging current will exceed the rated current of the controller, the controller will limit the charging current to the rated current.
5. With internal temperature detection function, when the controller temperature rises to 75℃, the controller will limit the charging current to half of the rated current. When the temperature reaches 90℃, the controller will turn off the charging and output to control the temperature.
6. Through RS485 communication interface, the controller can be connected to the master computer. You can set monitoring and control parameters from the master computer.
7. Use high‑quality components and advanced power conversion circuits, the maximum conversion efficiency can be over 98%, the full load efficiency can be 97%.
