12V 24V 48V 20A 30A 40A 50A 60A PWM Solar Controller

12V 24V 48V 20A 30A 40A 50A 60A PWM Solar ControllerSolar controller is mainly used for solar off-grid power generation system, can automatically control multiple solar panels for battery charging equipment, coordinate the efforts of solar panels, battery, load, monitoring, charging status, display panels for battery charging current, voltage and battery, can effectively prevent the battery overcharge, the function of the meter and the short circuit.PWM is the pulse width modulation, refers to the digital output of the microprocessor to control the analog circuit, is a digital coding method of the analog signal level.Digital control of analog circuits can greatly reduce the cost and power consumption of the system.The electrical structure of PWM solar charge controller is relatively simple, mainly consists of a power main switch, a capacitor, a drive and a protection circuit, which is actually equivalent to a switch, the component and the battery are connected together, the voltage of the component will be pulled down to the voltage of the battery pack.  Product Features:1) voltage automatic identification system12V/24V or 48V automatic identification2) humanized LCD display and double bond operation man-machine interface3) full use of technical data set and modify4) efficient smart PWM three charging5) can choose the loading control template, in the evening time can be seton the street6) reliable protection: overvoltage, short circuit, overload, overcharge, overdischarge protection function7) accurate temperature compensation, correct charging and dischargingvoltage, automatically prolong the service life of the battery8) input terminal positive and negative extreme reverse connection protection9) power set parameters of the controller can be reset to default.Specification:Model20A30A40A50A60ASystem voltage12V/24V Automatically switch, 48V    Solar panel input max voltage50V(12/24V),100V(48V)    Self loss≤13MA    Max charge current20A30A40A50A60ALVD10.5V(9-11V),21V(18-22V),42V(36-44V)LVR12.6V(11-13.5V),25.2V(22-27V),50.4V(44-54V)Floating voltage13.8V(13-15V),27.6V(26-30V),55.2V(52-60V)Increase the charge14.4V/28.8V/57.6V The battery voltage is below12V/24V/48V Start extra charge for 2 hours.Battery overpressure production15V/30V/60VInput reverse connection protectionYes    Load over current protectionYes,every two seconds to restartCharging modePWM    Operating temperature-20ºC-+55ºC    Terminal scale28-10AWG    Waterproof levelIP32    Product size(mm)187*90*47(20-30A)195*107*50(40A)187*122*57(50-60A)Packing size(mm)200*102*53210*118*59200*132*63Weight780g850g Details images:FAQ:When can l get your solar controller price?
