11.6 Optional Settings for the PV plant Monitoring System
11.6.1 Setting the communication period of Sunny Central String-
Monitors
The communication period is the time period during which the Sunny Central String-Monitor Controller
communicates with the Sunny Central String-Monitors. Upon leaving our factory, the default
communication period is set from 10:00 hours (10:00 a.m.) to 15:00 hours (3:00 p.m.). If you want
to change the communication period follow the instructions below.
Setting the communication period of all Sunny Central String-Monitors
1. Set the parameter "MoniTmComOn" to the monitoring start time.
2. Set the parameter "MoniTmComOff" to the monitoring end time.
3. Select [Save].
☑ Setting the communication period of all Sunny Central String-Monitors is now complete. Check
the monitoring period settings according to the instructions below.
11.6.2 Setting the monitoring period of Sunny Central String-
Monitors
You can set the monitoring period of the Sunny Central String-Monitors via the parameters of the
Sunny Central String-Monitor Controller. You can set the monitoring period for all the Sunny Central
String-Monitors or allocate a separate monitoring period to each group of Sunny Central String-
Monitors.
Selecting the monitoring period
The monitoring period must never be outside the time period set for the Sunny Central
String-Monitors to communicate with the Sunny Central String-Monitor Controller. This time
period can be set via the parameter "MoniTmComOn" and "MoniTmComOff".
Setting the monitoring period of all Sunny Central String-Monitors
1. Set parameter "MoniTmGrAllOn" to the monitoring start time.
2. Set parameter "MoniTmComOff" to the monitoring end time.
3. Select [Save].
