6.7.5.
Performance Ratio
[0] [Plant]
The follower inverters in the network will use the value from the irradiation sensor connected to
the master inverter for their performance ratio calculation. When follower inverters are installed
in a different environment than the master inverter, individual irradiation sensors can be con-
nected to them to obtain a more accurate calculation of the performance ratio.
Select 'Enable' to receive notification when performance ratio falls below a limit value.
If the irradiation falls below 0.20 W/m
2
, notification of performance ratio below limit will not be
sent.
Note:
The PV array settings of the inverter must be configured before the performance ratio can
be calculated. For further details refer to [Inverter → Setup → Calibration].
