Communication and Monitoring

8 Communication and Monitoring

8.1 Communication Interface

8.2 Communication types

SolarRiver inverters have communication interface RS485 and /or RS232 depending on model. Output voltage,

current, frequency, fault information, etc., can be delivered to a PC or other monitoring equipment via the

RS485/RS232.

SolarRiver inverters come with one or both of the following types communication facility depending on

model.

RS232 is a standard communication interface within 12m. It transmits data between PC and one SolarRiver

series inverter (Figure 22).

Only one inverter can be connected with a PC at one timethrough RS232 port. This facility is generally

used for single inverter communication, software update and testing by service person.

RS485 allows upto 32 inverters to communicate at the same time. But the total cable length should

not be more than 1200m. SolarLog can be used for monitoring multiple inverters at the same time.

Users can browser the PV plants operating data collected by SolarLog through PC. Connecting the

system as blow (figure 24), user can easily monitoring the PV power station.
