SMPPT30D 30A 12V24V auto work
SMPPT solar charge controller is multi-stage Maximum Power Point Tracking (MPPT) photovoltaic battery charge controller with our own technology. It’s main topology adopts in Buck conversion circuit, and uses MCU to adjust the solar panels working point intelligently in order to make the solar panels output its maximum power. When the circumstances change, the working point of solar panels deviate from the maximum power point, MCU will adjust the solar panels working point based on MPPT calculation to make the solar panels back to the maximum power point again. Compared with PWM controller, MPPT controller can increase the output power of solar panels by 5%~30%. The output power increasing proportion is affected by the factors such as solar panels property, humidity and light intensity. The controller uses wall-mount installing. Connecting terminal makes the wiring area bigger and wiring loss less.
  • Advanced MPPT maximum power point tracking technology, tracking efficiency not less than 99.5%
  • Using high-quality components to improve system performance, the maximum conversion efficiency up to 97%
  • Fast maximum power point tracking speed, ensuring tracking efficiency while tracking
  • Accurate Identification and Tracking of the Maximum Power Point
  • Reliable maximum PV array input power Automatic limit function to ensure no overload under any conditions
  • Wide PV array maximum power point operating voltage range
  • The use of LCD design, dynamic display equipment operating data and work status
  • Accumulated Charge and discharge recording function
  • Various load control modes: manual mode, light control mode, dual time mode and debug mode
  • Adaptable to Sealed,Gel,Flooded and other customized battery type
  • USB output
