EPEVER Tracer3910BPL Solar MPPT Controller 15A 12/24V, 100V Input

EPEVER Tracer3910BPL — Solar Controller with MPPT Technology

In professional photovoltaic applications, maximizing equipment efficiency and reliability is crucial. The Tracer3910BPL from EPEVER combines the functions of an advanced MPPT charge controller and an integrated LED driver. This provides not only up to 30% higher charging efficiency compared to PWM controllers but also flexibility for applications such as solar LED lighting. This model supports 12/24V systems with automatic voltage detection and offers a charging current of up to 15 A, enabling efficient energy management even in demanding installations. Its IP67 rating ensures durability against harsh conditions—including water immersion—making it ideal for outdoor use.

Higher Efficiency and Flexible Charging

Thanks to MPPT (Maximum Power Point Tracking) technology, the controller optimizes solar panel output to achieve maximum efficiency, even under varying light conditions. Support for both lead-acid batteries (gel, flooded) and lithium batteries (including LiFePO4) allows users to tailor the system to specific requirements. An automatic lithium cell activation function ensures the safe and efficient charging of modern batteries.

Integrated LED Driver and Load Control

The Tracer3910BPL features an integrated LED driver that offers an output current of up to 4.5 A with dimming capabilities. This makes it ideal for applications such as solar street lighting, where energy consumption can be optimized and continuous operation ensured. Multiple load control modes allow the device to be adapted to various operating scenarios, enhancing its versatility.

Protection and Durability

The controller is equipped with comprehensive protection features, including protection against overload, short-circuit, overvoltage, overheating, and reverse polarity. With an MPPT voltage range from (battery voltage +2 V) to 72 V and a maximum PV panel input voltage of 100 V, the device is capable of handling higher input values. Temperature compensation of the charging voltage (-3 mV/°C/2V) ensures a long service life for connected lead-acid batteries.
