Golden Solar! Advance Power! Green Life!
● 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
