Product advantage

LDSOLAR is a high-tech enterprise focusing on the R&D, production and sales of solar controllers. We have a professional and experienced R&D team and a high-quality production team.

We mainly provide PWM solar controllers represented by Land Dream, Sky Dream and Ocean Dream,power range from 10A to 60A,voltage 12V,24V and 48V. 

and MPPT solar controllers represented by Tracer Dream. power range from 10A to 100A, and voltage are 12V-24V-48V,Max Solar input voltage can reach 200V. Using imported 32-bit chips and a new generation of self-developed MPPT algorithm, the controller has higher sampling accuracy and faster response speed, effectively increasing the utilization rate of solar panels by 20% to 30%.

We can provide WiFi/Bluetooth communication and 24-hour online APP free service. At the same time, We have also obtained CE, RoHS, IEC62109 certification and related technical inventions, appearance patents. We engage in the principle of win-win and can provide OEM and ODM customized services, cost-effective products.

Important Safety Information

❖ It is better to install controller in the room. If install the controller outside, please keep the environment dry, avoid direct sunlight

❖ The controller will be hot in process of working, please keep the environment ventilation, away from flammable.

❖ The Voc of solar panels is high (especially 24V/48V system, please take care

❖ The battery had acidic electrolysis, please put on goggles during installation. If you accidentally exposed to electrolysis, please rinse with water

The battery has huge power; prohibit any conductor short circuit the positive and negative pole of battery. Suggest to adding a fuse between battery and controller. (Slow motion type, the action current of the fuse should be 1.5 times rated current of controller:)
