MPPT LCD Display 10A 20A 30A 40A with WIFI 12V/24V Solar Panel Battery Regulator Charge Controller Dual USB LifePo4 or Lithium
MPPT1 series products adopt DC/DC converting technology and MCU technology. It can adjust the working point of the solar array intelligently to make the solar array realize the maximum power output. When the external condition changes ,MPPT controller bases on the MCU theory to track the maximum working point of solar panels, this can improve the using efficiency of the solar panels and decrease the solar generating costs. Compared with PWM solar charge controllers, MPPT improve the output efficiency of solar panel by 5% to 30%(the output increasing proportion affected by the factors such as the attribute of solar panels, environmental temperature and lighting conditions).
There are optional 10A 20A 30A 40A model:
