Product Description

SDC300V-100A solar intelligent controller with LCD display 


Sandi Series Solar Charge Controller is a smart PV controller designed for off-grid PV power system. It has good running performance with LCD display and convenient operation. And also automatically control solar cell cut or connect ordinarily according to the change of battery voltage. This controller makes a full advantage of solar cell resource and also keep battery safe and reliable.


To meet different power stations’ need, there are 24V48V96V120V192V220V

240V 360V480V and other normal series voltage level base on different battery voltage of off-grid PV power station system project.


Technical Features:

  • The solar charge controller adopts industrial-grade chips to ensure the stable feature of controller
  • Excellent EMC design
  • High efficient PWM charging technology which has three charging stages (buck charging stage, equalize charging stage and float charging stage), and improves battery storage efficiency and charging efficiency.
  • Advanced battery activation technology which increases battery lifetime 30% at least and improves the system performance
  • The 120a solar charge controller adopts imported IGBT power module or MOSFET as electronic switch which can improve the stable performance of controller. There aren’t any mechanical switches in the system
  • LCD will display the system status and working parameters
  • Parameters setting flexibly
  • Users can parallel connect lots of the controller is a system
  • Fully enclosed duct design and high speed fan for cooling making the controller working in a variety of harsh environments
  • DC output function (Optional)
  • Standard Modbus protocol for RS-485 communication to extend the communication distance (Optional)
  • The 120a solar charge controller will alarm when the system status is abnormal
  • New SOC method displays battery power accurately
  • With power generation statistics function to facilitate the view of power generation of daily, month and total
  • There is temperature compensation function which will compensate the temperature according to different battery type
  • The 120a solar charge controller adopts graphical dot-matrix LCD and 4 buttons as HMI for full menu and easy operation
  • RTC time function
  • Wall mounting type is easy for installation
