Tracer-BN Series MPPT Solar Charge Controllers (20A-40A) by Epever

Epever's Tracer-BN series MPPT Solar Charge Controller. These rugged products are economical, practical, and long-lived. They are based on Epsolar's typical negative design and advanced MPPT control algorithm, with a die-cast aluminium design for heat dissipation.
With the MPPT control algorithm, the Tracer-BN series of products can quickly and accurately track the photovoltaic array's maximum power point (MPP) in any situation to obtain the maximum solar energy in time, which remarkably improves energy efficiency.

With the Modbus communication protocol interface, it is convenient for customers to expand applications and monitor various applications such as telecommunication base stations, household systems, caravans and RVs, street lighting systems and wilderness monitoring systems.
The all-around electronic fault self-test function and enhanced electronic protection function help prevent damage to system components caused by installation errors or system failures.
