FEATURES
Industrial blocking electricity design structure.
High reliability, anti- interference, efficiency, EMC, Easy installation and maintenance.
Advanced double Micro-Processor (MCU) control circuit structure to separately processing the real-time control and the running management, to ensure and allow real-time control MCU to fulfill flexible controller configuration.
Based on the EXPERT CONTROL SYSTEM, to optimize SOC for batteries charge and discharge.
Three equalized/boost/float regulation is used. The regulation voltages are adjustable via the keypad and display. Up to four stage bank switching can be used which allows taper charging in the boost mode and low speed switching regulation in the float mode.
Optimized control for calculating of discharge-rate and temp compensation, to allow exact discharge depth, and sure the batteries long life using.
Exact remote digital temp sensor(±0.1°C),for the battery temp measurement
Full multi- parameter control
Multi PV array charge input (4, 6 choose)
240×128 dots STN GRAPHIC LCD of wide running temperature, 4 buttons keyboard, to form operate display interface. Only easily move cursor to check parameter and setting.
Power MOSFET drive board, interface board, control board, use isolated work power. Dada exchange of board to board, use PHOTOCOUPLE to isolate electricity. A/D Sample channels also isolated. Integrated electricity isolation to allow high anti- interference and security of program running.
High performance 12 bit A to D converter,to achieve precise A/D resolution rate
Hall current sensor used for each PV array changing current, load current and generator current sample circuit. To get synchronization sample, no power losing current sample, as well as isolated electricity sample. Isolated amplifier also used for each voltage sample channel.
Power MOSFET drive, use 5 times rating current design and low resistance MOSFET module. To get very low power loss, overload ability, and good running in impact load.
