20A MPPT Solar Charge Controller With WiFi Bluetooth Device 12V/24V For Flood LifePo4 Lithium Battery-20A-12V24V-

20A MPPT Solar Charge Controller with WiFi Bluetooth Device 12V/24V For Flood LifePo4 Lithium BatteryMPPT1 series products adopts DC/DC converting technology and MCU technology. It can adjust the working point of the solar array intelligently to make the solar array reze 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,envmental temperature and lighting conditions).There are optional 10A 20A 30A 40A model：ModelBattery VoltageMax solar panel input10A12V100V  120W24V100V  240W20A12V100V  240W24V100V  480W30A12V100V  360W24V100V  720W40A12V100V  500W24V  100V  1000WFeatures:1. Self-made algorithm,fast and accurate lock MPPT point,within 10 seconds,accuracy is greater than 99%,MPPT peck conversion efficiency 98%.2. Four-stage charging:high current charing at MPPT points,float charging,absorption charging,equzed charging.3.Used for lead-acid batteries/batteries. Can be used for lithium battery(LiFePO4 battery,ternary lithium battery),when the lithium battery is low voltage protected,the battery can be activated.4. External temperature sensor,accurate temperature compensation.5. PV input maximum voltage:100V.6. The system voltage is 12V/24V automatically identification.7. Communication function(with built-in or external WIFI,Bluetooth, module),providing standard MODBUS communication protocol.Mobile APP Monitoring Display:PAYMENT/SHIPPINGPAYMENT/SHIPPING duties,es and charges are not included in the item price or shipping charges.
