Big LCD, visualized display of operation statusesthrough flow charts, intelligent icon touch buttons, tabular data, event records, etc. Visualization of parameters of the inverter by means of communication with a computer via a RS232/RS485 interface with henlp of intelligent monitoring software of the inverter.
Intelligent battery management
Intelligent battery charge: Adjustment of the battery charge parameter according to the battery configuration of the user, and swithcing between equalizing charge and floating charge, temperature compensating charge,and discharge management according to the power supply conditions, which may make the battery life longer and reduce burden of the administrator. Intelligent battery fault detection: Measurement of single parameters, display of the measurement results on the LCD, and immediate alarming and notigication for the administrator upon any battery fault.
* Personalized settings:
Proper adjustment of the input parameters according to the input power supply conditions.
