Mppt Solar Charge Controller Solar Panel Mppt Lcd Display 10a 20a 30a 40a With Wifi 12v/24v Battery Regulator Dual Usb Lifepo4

Mppt Solar Charge Controller Solar Panel MPPT LCD Display 10A 20A 30A 40A With WIFI 12V/24V Battery Regulator Dual USB LifePo4 MPPT LCD Display 10A 20A 30A 40A with WIFI 12V/24V Solar Panel Battery Regulator Charge Controller Dual USB LifePo4 or LithiumMPPT1 series products adopts DC/DC converting technology and MCU technology. It can adjust the workin 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 workin 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: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,equalized charging.3. 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,GPRS module),providing standard MODBUS communication protocol. REMINDER:1.The price you paid for the item excludes any customs tax.We will not shoulder any duties in destination country.2.Please check with your country customs office to determine what these additional costs will be prior to bidding/buying.3.All informations(products model No.,test result,specification,features,pictures,ect) that we provided are just for reference, Details pls refers to the real prodcut, instruction you received. All datas are our internal lab test results, and it might have a little discrepency upon different surrounding, pls refers to the exact result of the products after installation.4.Since 1000w wind turbine is very big and very heavy, so normally suggest to sh by sea, if by air, pls check the exact price for each country.Dear customers:Your positive comments is the driving force for our continuous improvement.
