*It has an efficient MPPT algorithm, MPPT efficiency ≥99.5%, and converter efficiency up to 98%.
*Charge mode: three stages (constant current, constant voltage, floating charge), it prolongs the service life of the batteries.
*Four types of load mode selection: ON/OFF, PV voltage control, Dual Time control, PV+Time control.
*Battery system voltage automatic recognition.
*Three kinds of commonly used lead-acid battery (Seal(GelF loaded) parameter settings can 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.
