40A MPPT Solar Panel Regulator Charge Controller 12V/24V Auto Focus Tracking

Model

40A MPPT Solar Panel Regulator Charge Controller 12V/24V Auto Focus TrackingThe most powerful current tracking MPPTOur BL912 controller is the most powerful focus tracking MPPT, with national solar utility invention certificate, product appearance certificate and related certification. A new technology is recognized by everyone and requires users to use and compare. Please be aware when purchasing, this product is to track the current power of the MPPT maximum power point to adjust the internal charging mode to maximize the conversion of light energy into electrical energy. It is not a MPPT that is tracked at a specific value of voltage low voltage or high voltage to constant voltage, so as to avoid misunderstanding. Thank you!The specifications:1. Rated voltage: 12/24 V2. Rated current: 40A3. Maximum voltage PV: 50 V4. Maximum input power PV: 400WFit For: Lithium battery, Solid battery, lead-acid batteryFeatures:1,MPPT tracking charge automatic focus, high charging efficiency, non-stop detection during loading, bidirectional focus tracking.2,Compared with normal solar charge controller, this MPPT controller could increase efficiency by 10%-30%.3,This controller can charge and discharge at the same time,This MPPT controller has perfect SOC function, control charge current, and supply power to the loads.4, Three phase charge management, effective battery protection, the battery is more5,Large LCD screen, adjustable load and discharge parameters,as long as you understand the characteristics of the battery Corresponding charging parameters, you can charge a battery. When the exit is off, It can be adjusted, which is more practical.Function:1,Always keep the battery on fill voltage condition.2,Prevent the battery from over-charging,Prevent the battery from over-discharging.3,Prevent the battery from reverse charging to solar panels during nights.4,Reverse Polarity Protection for Battery,Reverse Polarity Protection for Solar Panels,When the battery voltage is low, the controller will automatically cut off the load from the system;If the voltage of battery is back to normal and the load will restart working.Thunder protection:1,According to the battery voltage grade, the controller can automatically set charge-off voltage, the load-off voltage, the load- restore voltage. (The parameter is default under 25℃ condition, locked by the CPU procedure, cannot adjust.)2,The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature.Note:The 12-volt battery is charged with an 18-volt solar panel, and the 24-volt battery is charged with a 36-volt solar panel. As long as the battery is connected, the system will automatically turn on. When the battery is connected, the charging parameters will be automatically set according to the battery voltage.Package Included:1 x Solar Panels Battery Charge Controller(Type as your choosed)1 x User Manual
