SMA SB 3300 - Manual (Page 2)

If your inverter is equipped with a communication component, then numerous measuring channels
and messages can be transmitted for diagnosis.
Measuring channel Description
dZac Change of the grid impedance
Error Identification of the current disturbance / error.
E-total Total amount of energy fed into the grid
Event-Cnt Number of events that have occurred
Fac Grid frequency
h-On Total number of operating hours
h-total Total number of operating hours for feeding operations
Iac-Ist Grid current
Ipv DC current
Mode Display of the current operating mode
Pac Generated AC power
Power On Total number of grid connections
Riso Insulation resistance of the PV system to the grid connection
Serial number Inverter serial number
Vac Grid voltage
Vpv PV input voltage
Vpv-Setpoint PV target voltage
Your inverter can be in various operating modes. These are displayed as status messages, which can
vary according to the method of communication.
Message Description
Derating Overtemperature in the inverter. The inverter will reduce its output to prevent
overheating. To avoid unnecessary output losses, the design of the PV plant
should be checked. Please inform your installer.
Disturbance Disturbance. This message appears for safety reasons and prevents the inverter
from connecting to the grid. Please inform your installer.
Error An error has been detected. Please inform your installer.
Grid mon. Grid monitoring
This message appears during the startup phase, before the inverter connects to
the grid; it usually appears in the morning and evening when there is little solar
irradiation an after an error has occurred.
MPP The inverter is operating in MPP mode. MPP is the standard display message
when operating under normal irradiation conditions.
Off Grid The inverter is in "Island" mode. This mode has been specially conceived for
operation in a stand-alone grid with a Sunny Island as grid controller.
Offset Offset adjustment of measurement electronics.
Riso Measurement of the insulation resistance of the PV system.
Stop Operation interrupted.
V-Const Constant voltage operation.
Waiting The conditions for connecting are not (yet) fulfilled.
DANGEr!
Electric shock caused by high voltage in the inverter.
Even when no external voltage is applied, high voltages can be present in the inverter.
The following work must only be carried out by qualified personnel:
• Electrical installation
• Repairs
• Modification
CAUTION!
risk of injury from touching the enclosure during operation.
Burns to the body.
• Only touch lid and display during operation.
NOTICE!
Overvoltage in the inverter if yellow LED flashes 4 times.
Destruction of the inverter.
• Inform your installer immediately if the yellow LED should
start flashing and the following display message appears.
Operation The display shows current values of your system. The displayed values
are updated every 5 seconds. The display is operated by tapping on it.
Tap once
The background illumination is switched on. After 2 minutes, the
illumination switches off automatically.
Tap again
The display switches to the next notification.
Display messages
In operation Upon error-free connection of the inverter to the grid, the following
messages are shown in turn after approximately one minute. Each
message appears for five seconds, then the cycle starts again.
Power produced on the current day
Operating state
Current feed-in power
Voltage of the PV generator
Total amount of energy fed into the grid
Total number of operating hours for feeding operations
Disturbance In case of a disturbance, the inverter will display the status "Disturbance"
and an error message. Please inform your installer.
The following messages will be issued:
Power produced on the current day
Operating state "Disturbance"
Operating state
Error message
Measured value at time of disturbance
Current measured value (only displayed if a measured value is
responsible for the disturbance)
DC Overvoltage
The DC input voltage connected to the inverter is too high.
Please inform your installer immediately.
State Description function
All LEDs
are on
Initialization The inverter is initializing.
All LEDs
are off
Deactivation The inverter has detected a DC input voltage that is
too high for safe operation.
Green LED

Feeding
Operation
The inverter is feeding power into the public grid.
Green LED
is flashing
Waiting, Grid
monitoring
The inverter monitors the grid and waits for the DC
voltage to reach a certain level so that it can start
feeding the grid.
Stop Operation interrupted.
Derating Inverter is overheated.
Red LED
is on
Error A ground fault has occurred, or one of the thermally
monitored varistors on the DC input side is defective.
Please inform your installer.
Yellow
LED is on
Disturbance The inverter is operating in "Permanent disabled"
mode. This can have several causes. Please inform
your installer.
