Inverter Comparison:
Sunny Portal gives you the option of inverter comparison for plants with at least 2 PV inverters.
Sunny Central inverters are not supported.
Based on daily yield, Sunny Portal calculates the specific yield for each active inverter and compares
this once a day with the mean value of the specific yields of all inverters. Should the specific yield of
an inverter by comparison with the average specific yield be below a configurable tolerance,
Sunny Portal will inform you by e-mail. How to configure the inverter comparison option is described
in Section 7.3.3 ”Setting Inverter Comparison” (page 45). The following table explains the meaning
of the inverter comparison symbols:
Setpoint monitoring:
Sunny Portal provides a setpoint monitoring option for all plants with Cluster Controller or Power
Reducer Box. In the "Setpoint monitoring" area, you can see whether the grid operator has specified
any setpoints for the active power limitation of your plant. If you wish, Sunny Portal can inform you by
e-mail about incoming setpoints for active power limitation and reactive power setpoint (fixed reactive
power or phase shift factor cos-phi). How to configure the e-mail notification for setpoint monitoring
is described in Section 7.3.4 ”Setpoint Monitoring: Setting the E-Mail Alert” (page 45).
In addition to setpoint monitoring, you should use the communication monitoring for the Cluster
Controller/Power Reducer Box (see Section 7.3.2). This monitoring option enables Sunny Portal to
identify whether or not the setpoint monitoring information may be outdated.

configured range. The yield of the last day is displayed.
Error Specific inverter yield is outside of tolerance for at least
one monitored inverter. Use the additional "Details" link to
