Tracer Dream 100V Series MPPT Solar Charge Controller

Tracer Dream 100V Series MPPT Solar Charge Controller

Tracer Dream 100V TU Series adopts MPPT technology. Max.100V solar input, 12V/24V auto work. 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.It adopted by common negative design and it can start from solar, Widely used in RV, ship and so on.

Golden Ratio Asymmetric Design

The controller adopts asymmetrical design, and the LCD screen is located at the golden section, with a harmonious proportion and beautiful appearance. It' s natural to put it anywhere in your home or in RVs.


Free USB Charging

Support the maximum 1A charging current, charge your mobile device faster 20A , 30A with 1 USB port

Main control chip

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

Make your system more stable and efficient, the main control chip adopts Stmicroelectronics, and the other components adopt Samsung and Fenghua Hi-tech 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 It can improve the utilization ratio of PWM controller by 20% to 30%.

Heat dissipation

Distinctive heat 

dissipation character

This time, we also made a brand-new upgrade design for the TD100V 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.


Support lithium battery, start from solar

Application is wider, especially in many fields such as lithium battery systems, RVS , communication base stations, etc.

Fast Tracking

Good Low Light

Fast Trackin

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 MPP in the case of multiple peaks.
