JNGE Power JN-MPPT - User Manual

JN-MPPT Solar Charge Controller User Manual
Ⅰ. Product Characteristics
1. Product overview
Thank you for choosing JN-MPPT buck type solar sontroller.
This series of products are based on polyphase synchronous rectifier technology and sharing-one-
cathode design. Adopting the advanced dual core processor architecture and MPPT control algorithm,
it has features such as high response speed, high reliability and high standard of industrialization etc.
With the MPPT control algorithm, can quickly track the maximum power point of pv array and get
real-time access to the biggest energy of solar panels in any environment. With polyphase
synchronous rectifier technology, JN-MPPT series are guaranteed to keep a high conversion
efficiency in any charging power environment. Compared with most of the BUCK products, JN-
MPPT series raise the utilization ratio of the solar system largely. Besides, with standard RS485
communication interface, can easily realize multiple devices in parallel, to the greatest extent, to
meet the demand of different monitoring function. It can be widely used in communication station,
household system, street lamp system and field monitoring system etc.
With comprehensive electronic fault self-test function and powerful electronic protection function,
can avoid system components damage in the greatest degree due to installation errors.
2. 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, can be used in all kinds of harsh conditions.
• R&D with the latest technology, can realize the multiple devices in parallel through the RS485
communication interface.
• With Polyphase synchronous rectifier technology, can achieve high conversion efficiency even in
low power charging environment.
• Combination of various tracking algorithm, 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, can still track the maximum power point accurately.
