Tracer Dream 75V Series MPPT Solar Charge Controller
Tracer Dream 75V Series MPPT Solar Charge Controller

Tracer Dream 75V Series adopts MPPT technology. It's also ran by 32 bits CPU, so stability and speed can be guaranteed. Based on the synchronous rectifier technology, the transfer efficiency of circuit can be increased up to 98.5%and the Pmax tracking accuracy up to 99. 5%. So our MPPT can trace the accurate Pmax in the shortest time (10~20s) , even when the sunlight changes rapidly. It can perfectly handle extreme weather or weak sunlight.

Good Looking Appearance

The controller of TD 75V series adopts rounded corners design, which makes it feel comfortable.

Free USB Charging

Support high current mode, the maximum 2.4A charging current charges your mobile device faster USB*2PCS

ARM architecture, high-quality 32-bit main control chip, improve charging efficiency comprehensively.

The main control chip adopts STMicroelectronics, and the other components adopt Samsung and Toshiba components to ensure the stability

and life of the controller.

The running program of the upgradeable frame structure guarantees the low loss of the controller and makes it more efficient.

High Tracking Accuracy,High Conversion Efficiency

TD series controllers use the latest MPPT algorithm to improve tracking efficiency and speed,reduce energy loss during tracking and reduce tracking time.

Distinctive heat dissipation character

This time, we also made a brand-new upgrade design for the TD75V series heat dissipation system, and the back MOS tubes are evenly distributed.

While ensuring a stylish and simple appearance, the heat dissipationis further improved.

Power Limited Protection

When the power of solar charging exceeds the rated power of the controller, Ldsolar controller will limit the input power, and work at the rated power of controller without damaging the controller.

In the system that the MPPT controller of Ldsolar is installed, the power of solar panel can be more than the rated power of controller. But cannot exceed 2 times.

Good Low Light,Fast Tracking

Under low light conditions, Ldsolar controller can still track to the MPP quickly. In the case of light changes during the day, It can track in time and accurately.

It can achieve good balance between low disturbance amplitude and quick response and also can identify the MPPT in the case of multiple peaks.
