PWM 20A 40A 60A Solar Power Regulator USB LCD Display Load Discharger Solar Chargercontroller

  Solarthon MPPT Solar ChargeAnd Discharge Controller 20A/40A/60AThe full name of MPPT is maximum power point tracking, which is an advanced charging method that can monitor the power generation voltage of the solar panel in real time, and track the highest voltage and current value, so that the system can charge the battery with the maximum power output. The maximum power point tracking mode of this series of controllers is completely automatic and does not require user adjustment. As the maximum power point of the solar panel varies with environmental conditions, the controller automatically tracks the maximum power point of the panel to ensure maximum energy extraction from the solar array. ModelSTB1220STB1240STB1260Maximum Charging Current20A40A 60ASystem Voltage12/24V automatic identification 12/24V automatic identificationLiFePO4 12.8V  120AHMPPT Charging Voltage
