The PV array is connected to the inverter via a DC breaker, the inverter is connected to the
grid via an AC breaker and a residual current device (RCD), and surge protection device
(SPD) are configured on the AC and DC sides respectively.
ShiniCube supports two flexible communication modes: RS485 and optional wireless
Zigbee. The topological structure of the communication connection is introduced below.
1) Single device communication mode 1 (RS485)
Communication between a single device and a PC
See the figure below for the connecting method, a pair of A/B terminals on the inverter is
connected to the A/B terminals on the RS485/RS232 or RS485/USB switch, and the other
end of the switch is connected to the computer.
