Product Detail

IP43 12V 24V MPPT Solar Controller 20A With Extensive Electronic Protection Specification : # Model : SMP-20A # Battery voltage : 12 / 24V Auto Select # Maximum battery current : 20A # Maximum PV power , 12V 1a,b) :300W ( MPPT range 15V to 75V ) # Maximum PV power , 24V 1a,b) : 600W ( MPPT range 15V to 75V ) # Maximum PV open circuit voltage : 75V # Peak efficiency : 98% # Self consumption : Less than 10mA # Protection : Battery reverse polarity ( fuse , not user accessible ) Output short circuit / Over temperature # Color : Blue # Weight : 0.56 kg # Protection category : IP43 ( electronic components ) IP22 ( connection area ) Principle : The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine . The intensity of sunshine being constant , the maximum output power decreases with the rise of the temperature . The temperature being constant , when the sunshine intensifies , the open circuit voltage of PV battery basically keeps unchanged . But the short circuit current increases substantially , thus the maximum output power increases substantially . This MPPT solar controller can intelligently regulate the working voltage of solar panels , letting the solar panels always work at Maximum Power Point of V-A curve . Compared with ordinary solar controller , this MPPT controller can increase the efficiency of PV modules by about 30 % . However , due to many different factors , such as the difference in solar panel making , the change the Sun illuminance , change in temperature , the efficiency of the controller etc. , the actually available increased rate is 10% - 30% . Feature : # # Automatic identification of system voltage level # Easy to install # Settable operation mode of Load # Battery low voltage disconnection ( LVD ) # Over current protection # Maximum efficiency 98% # Simple button operation # Intelligent MPPT charging mode # Adjustable charge-discharge control parameters # Battery reverse-discharge protection # Battery reverse connection protection
