Main Features
12/24/36/48V automalic recognition
Optional APP version for Bluetooth communication
Real-lime energy slatistics funclion
Perfect EMC & thermal design
A combination of multiple tracking algorithms enables tracking the maximum power point quickly and accurately
Innovative Max Power Point Tracking(MPPT) technology, tracking efficiency >99.9%
Full digilal technology, high charge conversion efficiency up to 98%
LCD display design, read operating data and working condition easily
Flexible System baltery selection: Liquid, Gel, AGM and Lithium
Exlends baltery life through accurale remote temperature sensor
The Controller is prolecled against over-temperature due to built-in power reduction function
Four slages ballery charging process: MPPT, boost, equalization, float
Dual automatic protection to avoid exceeding the raled charging power and current
Multiple load control modes: Aiways on, Street lamp, User-defind Mode
Two USB interfaces(only -EU model)
lOT Wireless communication or Bluetooth communication functions optional
With the wireless communicalion function of the lOT , the controller can be connected remotely through loT'GPRS
Monthly charging data can be calculated and displayed by grouping and graphs
Based RS-485 standard Modbus protocol with R.11 interface lo maximize the communication needs of different occasions.
Full automatic electronic protect funclion for increased charge controller availability
