3 Years Warranty 60A 12/24/36/48V Auto MPPT Solar Controller

Main Features:

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 IV curve, and the controller can still trace the Max. Power Point.

3. Builtin 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. Builtin 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.
 


Protections.
1. Waterproof protection
Waterproof degree::IP32.

2. Input power limit protection
When the PV power exceeds the rated power, controller will limit the PV power under the value of rated power so as to prevent the controller from being damaged, the controller will charge by limited current.

3. Battery reverse connection protection
Battery reverse connection will not damage the controller but the system will stop working.

4. The voltage of PV input terminal is over value
When the voltage of PV input terminal is over value, controller will shut the PV input automatically.

5. Short circuit protection of PV input terminal
Load short circuit will not damage the controller but controller will stop output.

6. Reverse charge protection at night.
Prevent the battery from discharge at night.

7. TVS lightning protection
 Over temperature protection
