  Product details

  SMPPT20D maximum power tracking controller 20A 12/24V automatic identification

  This controller is a solar charge and discharge controller with MPPT function independently developed by our company. The main topology of the controller adopts the Buck conversion circuit, and the MCU is used to intelligently adjust the operating point of the solar battery pack, so that the solar battery pack can output the maximum power under the current environmental conditions. When the working point of the solar cell group deviates from the maximum power point after the environmental conditions change, the MCU of the controller adjusts the working point of the solar cell group according to the MPPT algorithm, so that the working point of the solar cell group returns to the maximum power point. Compared with ordinary solar charge controllers, MPPT controllers can generally increase the output power of the solar battery pack by 5% to 30%. The increase in output power is affected by the characteristics of the solar battery pack, temperature and light intensity. The whole machine adopts wall-mounted installation. The wiring method uses standard wiring terminals to lead, the wiring area is larger, and the line loss is smaller.
