All-in-one solar charge inverter V1.0 50
5. Other functions
5.1 Dry contact
Working principle: This dry contact can control the ON/OFF of the diesel generator
to charge the battery. ① Normally, the terminals are that the NC-N point is closed
and the NO-N point is open; ② When the battery voltage reaches the low voltage
disconnection point, the relay coil is energized, and the terminals turn to that the
NO-N point is closed while NC-N point is open. At this point, NO-N point can drive
resistive loads: 125VAC/1A, 230VAC/1A, 30VDC/1A.
5.2 RS485 communication port
This port is an RS485 communication port which comes with two functions:
①
RS485-2 allows direct communication with the optional host computer
developed by our company through this port, and enables monitoring of the
equipment running status and setting of some parameters on the computer;
②
RS485-1/RS485-2 also allows direct connection with the optional RS485 to
WiFi/GPRS communication module developed by our company through this
port. After the module is selected, you can connect the all-in-one solar charge
inverter through the mobile phone APP, on which you can view the operating parameters and
status of the device.
As shown in the figure:
RS485-1: Pin 1 is 5V power supply, Pin 2 is GND, Pin 7 is RS485-A1, and Pin 8 is RS485-B1;
RS485-2: Pin 1 is 5V power supply, Pin 2 is GND, Pin 7 is RS485-A2, and Pin 8 is RS485-B2;
5.3 USB communication port
This is a USB communication port, which can be used for USB communication with
the optional PC host software. To use this port, you should install the corresponding
"USB to serial chip CH340T driver" in the computer.
