Product details
Model Number: ST-MPPT-JN4850A
Brand Name: Shenten
Key Specifications/Special Features:
Product features Advanced MPPT maximum power point tracking technology, and tracing efficiency not less than 99.5%. Compared to common PWM algorithm, it achieves 15% -20% more efficiency. Using high quality imported components and advanced power conversion circuit, the maximum conversion efficiency can reach more than 98%; full-load efficiency can reach 97%. Aluminum metal for structure, JN-MPPT series can be used in all kinds of harsh conditions. R&D with the latest technology, JN-MPPT series can realize the multiple devices in parallel through the RS485 communication interface. With polyphase synchronous rectifier technology, JN-MPPT series can achieve high conversion efficiency even in low power charging environment. Combination of various tracking algorithm, JN-MPPT series can track the maximum power point quickly. Dual wave and multiple wave tracking technology, when the panels are in partial shade or when a single panel is damaged, JN-MPPT series can still track the maximum power point accurately. Four sections of charging ways: MPPT charge- equalizing charge- improving charge- floating charge.
12/24/48 V automatic identification function.
Support for data storage, storage time can be up to 10 years.
With current-limiting charging mode, when the input power of the photovoltaic panels is too large, the charging current exceeds the rated current of the controller. The controller will limit the charging current to the rated current charge.
With internal temperature detection function, when the controller temperature rises to 75 degrees, the controller will limit the charging current to half of the rated current. When the temperature reaches 90 degrees, the controller will shut down of charging and output to control the temperature.
Through the RS485 communication interface, controller can be connected to the upper machine. You can set up monitoring and control parameters etc from the upper machine.
The battery temperature compensation function.
With a wide range of operating voltage of PV array maximum power point.
With over charge, over discharge, over temperature, over load and reverse connection protection functions.
