2.1 Safety Information
This section contains safety information that must be observed at all times when working on or with
the product.
To prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and observe all safety information at all times.
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the
DC conductors and the live components of the inverter. Touching the DC conductors or the live
components can lead to lethal electric shocks. If you disconnect the DC connectors from the
inverter under load, an electric arc may occur leading to electric shock and burns.
• Do not touch uninsulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed and commissioned only by qualified persons with the
appropriate skills.
• If an error occurs, have it rectified by qualified persons only.
• Prior to performing any work on the inverter, disconnect it from all voltage sources as
described in this document (see Section2.2 "Disconnecting the Inverter from Voltage
Sources", page7).
Danger to life due to electric shock
Touching an ungrounded PV module or array frame can cause a fatal electric shock.
• Connect and ground the PV modules, array frame and electrically conductive surfaces so
that there is continuous conduction. Observe the applicable local regulations.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• Do not touch any parts other than the lower enclosure lid of the inverter during operation.
Damage to the display or the type label due to the use of cleaning agents
• If the inverter is dirty, clean the enclosure, the enclosure lid, the type label, the display and
the LEDs with a damp cloth only.

2.2 Disconnecting the Inverter from Voltage Sources
Prior to performing any work on the inverter, always disconnect it from all voltage sources as
described in this section. Always adhere to the prescribed sequence.
Destruction of the measuring device due to overvoltage
• Only use measuring devices with a DC input voltage range of 1,000 V or higher.
Procedure:
1. Disconnect the circuit breaker and secure it against reconnection.
2. If an additional DC load-break switch is available, switch off the DC load-break switch and
secure against re-connection.
3. If an ESS is plugged in, remove the ESS.
4. If the multifunction relay is used, switch off any supply voltage to the load.
5. Wait until the LEDs, the display and if necessary, the load connected to the multi-function relay,
are switched off.
6. Use a current clamp to ensure that no current is present in the DC cables.
7. Remove all screws of the lower enclosure lid using an Allen key (AF3) and remove the
enclosure lid.
8. Release and remove all DC connectors. Insert a
slotted screwdriver or an angled screwdriver
(blade width 3.5mm) into one of the slide slots
and pull the DC connectors out downwards. Do
not pull on the cable.
9. Ensure that no voltage is present at the DC inputs of the inverter.
10. Use a suitable measuring device to check that no voltage is present at the AC connecting
terminal plate between L and N and L and PE. Insert the test probe (maximum diameter:
2mm) in each round opening of the terminal.
11. Flip the display up to have more space to make the measurement. Loosen the screw on the
display.
☑ The display clicks into place.
12. Ensure that no voltage is present between any terminal of the multifunction relay and PE of the
AC connecting terminal plate.

Damage to the inverter due to electrostatic discharge
The internal components of the inverter can be irreparably damaged by electrostatic
discharge.
• Ground yourself before touching any component.

3 Cleaning the Inverter
3 Cleaning the Inverter
Damage to the display or the type label due to the use of cleaning agents
• If the inverter is dirty, clean the enclosure, the enclosure lid, the type label, the display and
the LEDs with a damp cloth only.
• If the cooling fins on the rear of the enclosure are dirty, clean them using a soft brush.
• If the air ducts on the top of the inverter are dirty, clean them using a soft brush.

4.1 LED Signals
The LEDs indicate the operating state of the inverter.
LED Status Explanation
Green LED glowing Feed-in operation
If an event occurs during feed-in operation, an event message will be shown on the display (for event messages see
the service manual at www.SMA-Solar.com).
flashing The conditions for feed-in operation are not yet met. As
soon as the conditions are met, the inverter will start feedin operation.
Red LED glowing Error
If an error occurs, the error message and the corresponding event number will be shown in the display. The error
must be rectified by a qualified person (for troubleshooting, see the service manual at www.SMA-Solar.com).
Blue LED glowing BLUETOOTH communication is activated.

Grid fault
The grid voltage or grid impedance at the connection point of the inverter is
too high. The inverter has disconnected from the utility grid.
Corrective measures:
• Check whether the grid voltage at the connection point of the inverter is
permanently in the permissible range.
If the grid voltage is outside the permissible range due to local grid
conditions, contact the grid operator. The grid operator must agree with
an adjustment of the voltage at the feed-in point or with a change of the
monitored operating limits.
If the grid voltage is permanently within the permissible range and this
message is still displayed, contact the Service (see Section11, page30
).
Grid fault
The utility grid has been disconnected, the AC cable is damaged or the grid
voltage at the connection point of the inverter is too low. The inverter has disconnected from the utility grid.
Corrective measures:
• Make sure that the circuit breaker is switched on.
• Make sure that the AC cable is not damaged.
• Make sure that the AC cable is correctly connected.
• Check whether the grid voltage at the connection point of the inverter is
permanently in the permissible range.
If the grid voltage is outside the permissible range due to local grid
conditions, contact the grid operator. The grid operator must agree with
an adjustment of the voltage at the feed-in point or with a change of the
