6.6.2 The 485-1/485-2 port

485-1/485-2 port is the extended 485 interface on SPH, which needs to be used in

conjunction with the RS485 Setting in the LCD menu to communicate with external

devices.

Figure 6.36

The master SPH will receive data from two meters simultaneously: Meter 1 (connected to

the Meter port on the SPH) should be connected to the grid-side bus and the

communication cable to the Meter port; Meter 2 should be connected to the output side

of the inverter and the communication cable to the 485-1/485-2 port. For details about

meter wiring, please see Section 5.4.2.

For Circuit Breaker (CB) 2, 3 and 4, the recommended specification is 25A/230V; for CB 1,

the recommended specification is 50A/230V.

The external VPP collector is connected to the 485-1/485-2 port with a network cable.

Once the communication is successfully established, the SPH will respond to the

instructions issued by the VPP.
