Welcome to ❤Fishkingshop❤ The series has high conversion efficiency, soft LCD backlight display, efficient MPPT algorithm, neat internal structure and beautiful appearance design. With the continuous optimization of the products, the series has its novel advantages:The various sampling data show on the screen, convenient user access.The PV input voltage ranges up to 150V, suitable for various
Specifications of solar panels.The power supplies uses low power chip, reducing static standby power consumption, reduce energy loss.Continuous optimization design, high cost performance.

Features:
It has an efficient MPPT algorithm, MPPT efficiency ≥99.5%，and converter efficiency up to 98%.
Clear definition LCD display function to check the device running data and working status, can also support to modify the controller display parameter. 
The controller has 3 stages charging mode, constant current charging(Bulk Charging), constant voltage charging and floatcharging for faster, more efficient, and safer battery charging.
Four types of load mode selection: ON/OFF, PV voltage control, dual time control, PV+time control.
The controller supports for charging of 12VDC, 24VDC, 36VDC and 48VDC batteries. Automatic recognition of the battery system voltage. The controller recognizes the system according to the voltage of the first battery connected and re-identified after the power failure was restored. 
Three kinds of commonly used leadacid battery (Sealed leadacid batteryGelbatteryFlooded battery) 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 will automatically maintain the charging power, and the charging current will not exceed the rated value.  
Support for RS485 communication protocol to convenient users integrated management and secondary development. 
Support PC software monitoring and WiFi module to realize APP cloud monitoring.  
The controller could be suitable for various types of PV modules and maximize the conversion of solar energy into electrical energy.
