Communication |
It has RS232 /RS485 and CAN BUS standard communication interface, it can real-time monitoring the capacity of battery bank, the voltage, current, environment temperature, and charging/discharging current. Communication protocol content can be written according to your inverter protocol. |
|
|
Alarm |
It has over-temperature, over charge, under-voltage, over-current, short circuit alarm |
|
It support connection mode via RS485 Parallel Communication
While in RS485 parallel communication, dial-up addresses of battery module are 1,2,3,4……14,15; By this method, we can be allowed to read each data depending on battery module. Any battery other than address 0 can be connected to the host computer; FF polling mode used as consulting mode.
