Epever 40A MPPT Solar Charge Controller for 12V/24V Auto

The Tracer-BN series solar charge controllers, designed with advanced MPPT control algorithm and die-cast aluminum for heat dissipation, are artistic, economical, and practical. The MPPT control algorithm enables these controllers to quickly and accurately track the maximum power point (MPP) of the photovoltaic array, ensuring maximum solar energy harvesting and remarkable improvement in energy efficiency, regardless of the situation.

With the Modbus communication protocol interface, customers can conveniently expand applications and monitor the controllers in various fields, such as telecommunication base stations, household systems, caravan systems, street lighting systems, and wilderness monitoring systems.

These controllers feature all-round electronic fault self-test and enhanced electronic protection functions to prevent damage to system components resulting from installation errors or system failures. The advanced MPPT technology ensures an efficiency of no less than 99.5%, while the high-quality components deliver a maximum conversion efficiency of 98%.

The controllers automatically identify the 12/24VDC system voltage or allow the user to define the working voltage. LED indicators provide clear and simple system status information. Four charging options are available: Sealed, Gel, Flooded, and User.

The controllers offer ultra-fast tracking speed, accurate recognition and tracking of multiple power points, and a reliable automatic limit function for maximum PV input power, ensuring no overload under any circumstance. The die-cast aluminum design ensures excellent heat dissipation characteristics.

Multiple load control modes are available, including manual control, light ON/OFF, light On+Timer, and time control. The connection sequence is Battery--Load--Solar Panel, and the system should be disconnected in the reverse order: Solar Panel--Load--Battery. The Tracer-BN series is a negative ground controller, allowing any negative connection of solar, load, or battery to be earth-grounded as required.

The Tracer-BN series is compatible with various accessories, including the Remote Meter (MT50), Remote Temperature Sensor (RTS300R47K3.81A), and USB to RS-485 converter (CC-USB-RS485-150U), enabling monitoring, setting, and firmware updates through PC software or mobile apps.

Overall, the Tracer-BN series solar charge controllers offer advanced features, high efficiency, and versatile communication options, making them suitable for a wide range of solar applications, from residential to industrial settings.
