Golden Solar! Advance Power! Green Life!

SMC3 Series MPPT Solar Charge Controller
SMC3 series is a max. power point tracking function with high efficiency MPPT solar charge controller, with 20-60A rated charge current, 12V, 24V,36, 48V system automatic recognition.
Key Features

 It has an efficient MPPT algorithm, MPPT efficiency ≥99.5%,and converter efficiency up to 98%

 Charge mode: 3 stages (constant current, constant voltage, floating charge), it prolongs service life of the batteries

 4 types of load mode selection: ON/OFF, PV voltage control, Dual Time control, PV+Time control

 Battery system voltage automatic recognition

 3 kinds of commonly used lead-acid battery (Seal\Gel\Flooded) parameter settings fcan be selected by the user, and the user can also customize the parameters for other battery charging

 It has a current limiting charging function. When the power of PV is too large, the controller automatically keeps the charging power, and the charging current will not exceed the rated value

● High definition LCD display function to check the device running data and working status, also can support modify the controller display parameter

 RS485 communication, we can offer communication protocol to convenient user’s integrated management and secondary development

 Support PC software monitoring and WiFi module to realize APP cloud monitoring

 CE, RoHS, FCC certifications approved, we can assist clients to pass various certifications
