All-in-one solar charge inverter V11 32
5. Other functions
5.1 Dry node
Working principle: This dry node 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 ;
This port is an RS485-2 communication port is an optional function, which is not available in the
standard machine.
This port is an RS485-1 communication port which comes with two functions:
① It 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 It 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 WiFi/GPRS APP, on which you can view the operating parameters and
status of the device.
As shown in the figure:
Pin 1 is 5V power supply, Pin 2 is GND, Pin 7 is RS485-A, and Pin 8 is RS485-B ;
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.
