Details:

 

 
Generally speaking, the MPPT controller’s energy utilization efficiency is 15%~20% higher than PWM controller. The MPPT efficiency can reach 99.97%.

Main Feactures:

 

1. Can be used in all kinds of bad environment with Aluminum frame.

 

2. Double crest or multi crest tracing technique design, when the solar panel is under shadow or part of the solar panel is damaged, multi crest will turn up in I-V curve, and the controller can still trace the Max. Power Point.

 

3. Built-in maximum power point tracking algorithm which could promote energy utilization efficiency of pv system. The charging efficiency is 15%~20% higher than PWM mode.

 

4. Adopting sorts of tracking algorithm to track the best working point of I-V curve promptly and accurately, the MPPT efficiency could reach to 99.9%

 

5. The use of advanced digital power technology, circuit energy conversion efficiency is as high as 98%

 

6. Four stage charging order mode: MPPT-equalizing charging-boost charging-float charging.

 

7. With current-limiting charging mode, when the power of solar panel is over-sized and charging current exceeds the rated current, the controller will lower the charging power, which enables the system to work under the rated charging current.

 

8. It can communicate with PC by communication wires and cables, read or set controller’s running parameters and monitor the system operation status.

 

9. The controller can realize networking operation by the link with telecommunication cable.

 

10. Have the fault code indication; it helps users confirm the system fault

 

11. 12V/24V/36V/48V auto identified.

 

12. Support data storage, the storage span can reach 5 years.

 

13. It can connect with LCD screen monitoring and the controller parameters are amendable.

 

14. Built-in temperature sensor, when the temperature exceeds the set value, the charging current will lower down followed by the decrease of temperature, so as to control the controller’s temperature rise.

 

15. With temperature compensation function to adjust the charge and discharge parameters automatically, which can improve battery service life.

 

16. Various system protection functions. Including over-charge, over-discharge, over-load, over-heat, the battery reverses connection protection and so on.

 

17. TVS lighting protection.
