MPPT Solar Panels Regulators

Product Detail

SSM30A  Instruction for use of a step-down MPPT Solar Panels Regulators

MPPT Solar Panels Regulators overview:

The controller is suitable for the automatic control of charging and discharging process in the solar energy off grid system. The charging mode of the controller is divided into MPPT and DC-DC, and the discharge process of the battery is optimized, which can prolong the service life of the battery and improve the performance of the system. Its comprehensive electronic protection function can prevent the user from installing errors and system failures to make the controller damaged. 

MPPT Solar Panels Regulators Functional characteristics:

1. System voltage automatic identification

2. Design of high speed and high performance 32 bit processor 

3. Excellent heat dissipation and EMC design 

4. Using MPPT and PWM two charging mode, effectively improve the charging efficiency of the battery board.

5. The use of large screen LCD LCD display and dual key man-machine interface, complete menu display and operation

6. User-friendly browsing interface, user-friendly operation 

7. Using power MOSFET as a switch, there is no mechanical switch 

8. Intelligent battery power indicator to facilitate the user to view the status of the battery 

9. Lead acid seals, colloids, openings and user selectable charging procedures 

10. External temperature sensor with high precision temperature compensation 

11. Parameter settings power down save function, no need to repeat settings, easy to use

12. With intuitive LED display, allowing users to understand the solar energy, the running state of the load

    13. With over charge, over discharge, overload protection, and electronic short circuit protection and anti back protection of battery. 

14. Lightning protection.




Controller panel:



1.The controller must be installed with the following dimensions

        Dimensions and mounting dimensions

       2. Wire preparation: first determine the length of the wire, determine the installation position, as far as possible to reduce the length of the wire in order to reduce the power loss, the wire section according to the 4A/mm - to choose.

3. first connect the battery, pay attention to positive and negative poles, do not reverse. If the connection is reversed, the controller indicator and the LCD screen do not have any indication but do not damage the internal components of the controller. If the connection is correct, the LCD has an initial display interface.

4. connect the wire of the solar panel, pay attention to the positive and negative 

poles, do not reverse connection; if there is sunshine, CHARGE indicator light will be flashing after 5S or charging, or check the connection is not. 

       5. At the end of is connected with the load, the LED source or load controller with the DC output positive and negative pole, note the negative, do not reverse, to avoid burning appliances.
