Visual inspection
Check the inverters and the cables for visible external damage. Contact your installer if you 󹻭nd any
defects. Do not perform any repair work yourself.
Maintenance and Cleaning
Have your installer check for proper inverter operation at regular intervals.
VISUAL INSPECTION, MAINTENANCE AND CLEANING

Symbols on the Inverter
Operation display.
Ground fault or varistor defective.
Please inform your installer.
An error has occurred. Please inform your installer immediately.
Tap to switch on the display light and switch to the next message.
Symbols on the Type Label
Beware of dangerous electrical voltage.
The inverter operates at high voltages. All electrical work
on the inverter may be carried out by quali󹻭ed personnel only.
erfolgen.
Beware of hot surface.
The inverter can become hot during operation. Avoid contact during operation.
Observe enclosed documentation.
The inverter must not be disposed of with the household waste.
Further disposal information can be found in the enclosed installation guide.
CE mark. The inverter complies with the requirements of the applicable EC
guidelines.
RAL quality mark for solar products. The inverter complies with the requirements of
the German Institute for Quality Assurance and Labeling.
Direct Current (DC)
Alternating current (AC)
The inverter is protected against penetration by dust particles and water jets from
any angle.
The inverter is transformerless.
AC
Abbreviation for "alternating current".
DC
Abbreviation for "direct current".
Derating
A controlled reduction in performance, usually dependent on component temperatures. Compared
with the (also common) practice of completely shutting down the device, the effect on the external grid
is smaller with derating.
Electronic Solar Switch (ESS)
The Electronic Solar Switch is part of the inverter's DC switch-disconnector. The
Electronic Solar Switch must be securely inserted into the bottom of the inverter and may
only be removed by quali󹻭ed personnel.
MPP (Maximum Power Point)
Operational point of the inverter, dependent on current / voltage of the PV generator. The actual
position of the MPP changes constantly, depending on the level of solar irradiation and the cell
temperature.
PV
Abbreviation for photovoltaics.
SMA Power Balancer
The SMA Power Balancer is a serial feature of the Sunny Boy. The SMA Power Balancer prevents the
formation of an unbalanced load > 5 kVA (in Italy > 6 kVA) during three-phase grid feed-in. To this
effect, 3 Sunny Mini Centrals are each connected via a control line to a 3-phase feeding unit.
Varistor
The varistors protect the electronics in the inverter from atmospherically coupled energy peaks, such as
those that can occur in the event of nearby lightning strikes.
EXPLANATION OF SYMBOLS GLOSSARY

If your inverter is equipped with a communication component, then numerous measuring channels
and messages can be transmitted for diagnosis.
Measuring channel Description
Balancer Displays the currently active operating mode of the inverter which is set
under the operating parameter "PowerBalancer".
Error Identi󹻭cation of the current disturbance / error.
E-total Total amount of feeding-in energy
Event-Cnt Number of events that have occurred
Fac Grid frequency
h-On Total number of operating hours
h-total Total number of grid-feeding operational hours
Iac 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 power supply line
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
Balanced The inverter has disconnected itself from the grid, or is limiting its output to
5 kVA over a 10 minute average. The inverter is part of a three-phase system
with two further inverters and equipped with the Power Balancer for preventing
unbalanced loads.
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 display appears during the start phase, before the inverter is connected to
the grid, predominantly in the mornings and evenings when the solar irradiation
is low and after an error.
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 is specially designed for operation in
island system.
offset Offset adjustment of measurement electronics.
Riso Measurement of the insulation resistance of the PV system.
Stop Interruption of operation.
V-Const Constant voltage operation.
waiting The switch-on conditions are not (yet) ful󹻭lled.
DANGER!
Electric shock caused by high voltage in the inverter.
Even when no external voltage is present, there can still be high voltages in the device.
The following work may be carried out by quali󹻭ed personnel only:
• Electrical installation
• Repairs
• Modi󹻭cation
CAUTION!
Risk of injury from touching the enclosure during operation.
Burns to the body.
• Only touch the lid and display during operation.
NOTICE!
Overvoltage in the inverter if yellow LED 󹢵ashes 4 times.
Destruction of the inverter.
• Inform your installer immediately if the yellow LED starts
󹻮ashing 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 message.
Display messages
In operation Upon error-free connection of the inverter to the grid, the following
messages are shown in turn after approximately 1 minute. Each
message appears for 5 seconds, then the cycle starts again.
Power produced on the current day
Operating state
Current feed-in power
Voltage of the PV generator
Power produced so far
Total number of grid-feeding operational hours
Disturbance In the event 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)
