Procedure:
1. Disconnect the circuit breaker and secure it against reconnection.
2. If an external DC load-break switch is installed, disconnect it from all voltage sources.
3. If an ESS is installed, carefully remove the ESS.
4. If the fault indicator relay is used, switch off the load supply voltage, if necessary.
5. Wait until the LEDs and the display have gone out.
6. Use a current clamp to ensure that no current is present in the DC cables.
7. Release and remove all DC connectors. Insert a
flat-blade screwdriver or an angled screwdriver
(blade width: 3.5 mm) into one of the side slots
and pull the DC connectors straight out. Do not
pull on the cable.
10.
Danger to life due to high voltages

4 Troubleshooting
4.1 Error Messages
Errors, disturbances and warnings are shown in the display and start in the first line with the word
"Error", "Disturbance" or "Warning". In the second line of the display, the cause of the error,
disturbance or warning is shown.
Message Cause and corrective measure
!PV-Overvoltage! !! - ! Overvoltage at the DC input. This can destroy the inverter.
DISCONNECT DC! This message is additionally highlighted by rapid flashing of the
backlight.
Corrective measures:
• Disconnect the circuit breaker.
• If installed, disconnect the external DC load-break switch.
• If an ESS is plugged in, remove it.
• Unlock and remove all DC connectors using a screwdriver
(blade width: 3.5 mm):
– Insert the screwdriver into one of the side slots.
– Remove the DC connectors.
• Check whether the DC voltage is below the maximum input
voltage of the inverter. If the DC voltage is below the maximum
input voltage of the inverter, reconnect the DC connectors to
the inverter.
If the DC voltage is above the maximum input voltage of the
inverter, check the PV system design or contact the installer of
the PV array.
• If this message is repeated frequently, disconnect the inverter
from voltage sources (see Section 2.2 "Disconnecting the
Inverter from Voltage Sources", page 7) and contact the
SMA Service Line.
If the red LED is glowing and the inverter displays the message Riso or the communication product
displays the message Insulation error, there is a ground fault in the PV array. The electrical
insulation between the PV system and ground is defective or insufficient.
If the inverter displays the event numbers 3501, 3601 or 3701, there could be a ground fault. The
electrical insulation from the PV system to ground is defective or insufficient.
Procedure:
In order to check the PV system for ground faults, perform the following actions in the prescribed
order. The exact procedure is described in the sections below.
• Check the PV system for ground faults by measuring the voltage.
• If the voltage measurement was not successful, check the PV system via insulation resistance
measurement for ground faults.
Test by Measuring the Voltage
Proceed as follows to check each string in the PV system for ground faults.
Procedure:
1.
Danger to life due to high voltages
• Disconnect the inverter from all voltage sources (see Section 2.2, page 7).
2. Measure the voltages:
• Measure the voltages between the positive terminal and the ground potential (PE).
• Measure the voltage between the negative terminal and the ground potential (PE).
• Measure the voltages between the positive and negative terminals.
If the following results are present at the same time, there is a ground fault in the PV
system:
☑ All measured voltages are stable.
☑ The sum of the two voltages to ground potential is approximately equal to the
voltage between the positive and negative terminals.
• If a ground fault is present, determine the location of the ground fault via the ratio of the
two measured voltages and eliminate the ground fault.
Example: Location of the ground fault
The example shows a ground fault between the second and third PV module.
3. If a definite ground fault cannot be measured and the message is still displayed, measure the
insulation resistance.
4. Reconnect the strings without ground faults to the inverter and recommission the inverter (see
Section 5, page 22).
Test by Measuring the Insulation Resistance
If the voltage measurement does not accurately indicate a ground fault, the insulation resistance
measurement can provide more detailed results.
total
The exact insulation resistance of a PV module can be obtained from the module manufacturer
or the datasheet.
For the resistance of a PV module an average value can be assumed: for thin-film PV modules
approximately 40 MOhm and for polycrystalline and monocrystalline PV modules
approximately 50 MOhm per PV module (for further information on calculating the insulation
resistance see the Technical Information "Insulation Resistance (Riso) of Non-Galvanically
Isolated PV Systems" at www.SMA-Solar.com).
Required devices:
☐ Suitable device for safe disconnection and short-circuiting
☐ Measuring device for insulation resistance
Device required for safe disconnection and short-circuiting of the PV array
The insulation resistance can only be measured with a suitable device for safe disconnection
and short-circuiting of the PV array. If no suitable device is available, the insulation
measurement must not be carried out.
Procedure:
1. Calculate the expected insulation resistance per string.
2.
Danger to life due to high voltages
• Disconnect the inverter from all voltage sources (see Section 2.2, page 7).
3. Install the short circuit device.
4. Connect the measuring device for insulation resistance.
5. Short-circuit the first string.
6. Set the test voltage. The test voltage should be as close as possible to the maximum system
voltage of the PV modules but must not exceed it (see datasheet of the PV modules).
7. Measure the insulation resistance.
8. Eliminate the short circuit.
9. Measure the remaining strings in the same manner.
☑ If the insulation resistance of a string deviates considerably from the theoretically
calculated value, there is a ground fault present in the that string.
10. Reconnect only those strings to the inverter from which the ground fault has been eliminated.
11. Reconnect all other strings to the inverter.
12. Recommission the inverter (see Section 5, page 22).
13. If the inverter still displays an insulation error, contact the SMA Service Line. The PV modules
might not be suitable for the inverter in the present quantity.

7. Remove the insertion tool from the clamping contacts of the connecting terminal plate.
8. Recommission the inverter (see Section 5, page 22).
If you have disconnected the inverter from all voltage sources (e.g. for configuration purposes) and
want to recommission it, proceed as follows.
Requirements:
☐ The circuit breaker must be correctly rated.
☐ The inverter must be correctly mounted.
Procedure:
1. Connect the grounding conductor to the inverter
and the enclosure lid.
2. Position the enclosure lid on the enclosure and tighten it using the four screws (torque: 2 Nm).
3. Insert the AC connection socket into the AC pin
connector on the inverter. If necessary, remove
the protective cap beforehand.
7.
Risk of fire due to tightening the screw within the ESS
A perfect contact between the ESS and the inverter is only guaranteed if the ESS plug remains
flexible.
• Do not tighten the screw in the plug of the ESS.
8.
Damage to the inverter due to moisture and dust intrusion
If the ESS is not plugged in or incorrectly plugged in during operation, moisture and dust can
penetrate the inverter. If the ESS is not correctly plugged in, this can cause contacts in the ESS
to wear or the ESS might fall out. This can result in yield loss and damage to the ESS.
Always plug in the ESS as follows:
• Securely plug in the ESS. The ESS must be aligned parallel to and flush with the
enclosure.
• Ensure that the gap between the ESS and the enclosure is no more than 1 mm.
9. If an external DC load-break switch is installed, switch it on.
10. Switch on the circuit breaker.
☑ The start-up phase begins.
☑ The green LED is glowing and the display alternates between the device type or
designation of the inverter, the firmware version and the configured country data set.
✖ The green LED is flashing?
The DC input voltage is still too low or the inverter is checking the utility grid.
• Once the DC input voltage is sufficiently high and the grid connection conditions are
met, the inverter will start operation.
✖ The red LED is glowing?
The inverter has detected a ground fault or one of the varistors is defective.
• Eliminate the error (see Section 4.2 "Red LED is Glowing Continuously", page 16).
✖ Yellow LED flashing?
An error or disturbance has occurred.
• Eliminate the error or disturbance (see Section 4.1 "Error Messages", page 11).
Procedure:
1.
Danger to life due to high voltages
• Disconnect the inverter from all voltage sources (see Section 2.2, page 7).
2. If other cables (e.g. data cables or network cables) are connected, remove them from the
inverter:
• Remove all screws from the enclosure lid and pull the enclosure lid forward smoothly.
• Remove the grounding conductor connection between the inverter and the enclosure lid
from the bottom of the enclosure lid.
• Remove the cables from the inverter.
• Establish the grounding conductor connection between the inverter and the enclosure lid.
• Position the enclosure lid on the enclosure and tighten it using the four screws (torque:
2 Nm).
3.
Risk of burns due to hot enclosure parts
Wait 30 minutes for the enclosure to cool down.
4. If the inverter is screwed to the wall mounting bracket, release the screw on the bottom side
between the inverter and the bracket.
5. If an additional grounding or a equipotential bonding is connected, release the cylindrical
screw M6x16 and remove the grounding cable.
6. Keep the inverter in a horizontal position when lifting it off the wall mounting bracket and
transporting it.
7. If the inverter is to be stored or shipped, pack the inverter and, if applicable, the ESS. Use the
original packaging or packaging that is suitable for the weight and dimensions of the inverter.
8. Dispose of the inverter in accordance with the locally applicable disposal regulations for
electronic waste.
