5. Other Functions
5.1 Dry contact Function
Working Principle: This dry contact can control the switch of diesel generator to charge
the battery. (1) Under normal circumstances, this terminal is closed at NC-N point and opened
at NO-N point; ② when the battery voltage reaches the low-voltage breaking point, the coil
of the relay is electrified, and the NO-N point is closed and the NC-N point is opened, at this
time, the NO-N point can drive resistive load 125VAC/1A, 230VAC/1A and 30VDC/1A.
5.2 RS485 Communication Function
There are 2 communication ports: RS485-1 and RS485-2, which have two functions:
①
RS485-2 communication port can communicate with lithium battery BMS in RS485
(need to be customized);
②
RS485-1 communication port can be connected with the selected RS485 to
WIFI/GPRS communication module independently developed by use. The Module, if
selected, can be connected with our inverter, and the operating parameters and
status of the inverter can be viewed through the mobile APP.
③
As illustrated in the figure:
Pin 1 is 5V power, Pin 2 is GND, Pin 7 is RS485-A and Pin 8 is RS485-B.
5.3 USB Communication Function
This is USB communication port, which can be used with our optional host computer (you need
to apply)
Software for USB communication, using this Port needs to install the corresponding "USB to
serial port chip CH340T Driver" in the computer.
5.4 CAN Communication Interface
Communication port can communicate with lithium battery BMS (need to be customized),
terminal left interface CNAL, terminal right interface CANH.
