Which MPPT controller is right for you!
The PWM controller provides a 1.5 years warranty, and the MPPT controller provides a 3 years warranty.
1.We promise that the solar controllers produced by our company are full power
2.We promise that never use old components, "Fake one, Fine 100,000RMB"
Worry-free after sales
1.During the warranty period, non-artificial product failures occur, our company promises to replace new one for free
2.After “three-step confirmation " to quickly identify.
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 MPP in the case of multiple peaks.
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.
Customized large-diameter red and black terminals (Patented)
*Customized large-diameter port is more suitable for solar systems that require large-diameter wires to reduce the voltage drop and losses in wires
*The red and black design allows customers to distinguish positive and negative more intuitively, and good customer experience
*The shrapnel is designed in the crimping frame to avoid breaking the wire and causing poor contact
32-bit ARM Main control chip, Make your system more stable and more efficient
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.
|1.Automatical Voltage Switch||2.Over charging and over discharging protection||3.Overload protection||4.Short Circuit Protection|
Ldsolar controller can switch the system voltage according to the battery voltage automatically
|Ldsolar controller can prevent the battery from over charging and over discharging and increasing the battery life.||Ldsolar controller will cut off output ,if the curent of output is more than 1.1 times rated current||When the solar panel or the Load is short circuit,Ldsolar controller can stop charging or turn off the output immediately.It can prevent battery from damaging|
|5.Reverse Connected Protection||6.Battery Over Voltage Protection||7.Auto Temperature Compensation||8.Over Temperature Protection|
|If the polarity of battery or solar panel is reversely connected ,Ldsolar controller will not be destroyed.After correcting the connection,Ldsolar controller will work normally.||When the voltage of battery was more than 16.5V(12V system),Ldsolar controller will turn off charging and output.||The in-built sensor in Ldsolar controller can sense the outside temperature and regulate the battery charging and over discharging.It can increase battery life upto 30%||When the temperature of inside controller is uptp 75℃，the controller will stop charging and discharging.|
|9.Lighting Protection||10.Multiple load work modes||11.Prevent Reverse Flow of Current||12.Battery Type Selection|
|Ldsolar controller could protect small induction thunder||Ldsolar controller can automtically detect when the day sets and night begins and set a working time.It can switch on /off the output automtically||During nighttime when voltage of battery is more than that of solar panel,current could start flowing from battery to panels,This could be very harmful for solar panel.Ldsolar controller ensures that the current always flow from panels to batteries,and never in the reverse direction.||Ldsolar controller is deigned for multiple battery type-Sealed,Gel,Flooded,LiFePO4 and LiO2 to ensure efficient charging.|
|13.Power limited Protection||14.Direct Power Supply Function||15.High-temperature charging power derating protection||16.Real-time energy statistics function|
|When the power from solar panel is more than output power,Ldsolar controller will limit the power from solar panel,and work at rated power of controller||Ldsolar controller can supply power from solar panel directly to the Load,it can increase the battery life.BUT BATTERY MUST BE CONNETED in the solar system||When the Temperature inside controller is more than 75℃,Ldsolar controller will derate to low power charging.||Ldsolar can show and count the Real-time energy in LCD|
