9.1.1 Measuring Channels
Measuring channels are measured values shown on the display. Additionally, you can read out
further measuring channels via a communication product.
Measuring channel Explanation
E-Today Total amount of energy fed in
Status Indicates the current operating state (see Section 9.1.2 "Status Mes-
sages", page 43).
Pac AC power supplied
Vpv PV input voltage
E-Total Total amount of energy fed in
h-Total Total number of operating hours in feed-in operation
Warning / Disturbance / Er-
ror Display of a current disturbance or error with corresponding error
message (for troubleshooting, see service manual at www.SMA-So-
lar.com). When certain disturbances occur, the disconnection value
and the current value are also displayed.
9.1.2 Status Messages
Status messages are shown in the second line of the display and always start with the word
"Mode". Status messages indicate operating states which do not represent errors or disturbances.
The inverter continues feeding into the utility grid.
Message Explanation
Derating This message can have several causes:
• Overtemperature in the inverter. The inverter reduces its power to prevent
overheating.
• External active power limitation via the Power Reducer Box and
Sunny WebBox. The inverter reduces its power output automatically due
to the grid operator's specifications. The Power Reducer Box transfers the
signal from the grid operator to the inverter via the Sunny WebBox.
Error The inverter has detected an error. The specific error message is also dis-
played (for troubleshooting, see service manual at www.SMA-Solar.com).
MPP The inverter is operating in MPP mode. MPP is the standard display message
when operating under normal irradiation conditions.
MPP-Peak The inverter is operating in MPP mode above its nominal power.
MPP-Search The inverter is calculating the MPP.
