4-String-OperationThe "4-String-Operation" function allows the DC inputs A and B of the inverter to operate in paralleland up to three strings to be connected to it in parallel. As a result, as opposed to normaloperation, up to four strings can be connected to the inverter. The inverter automatically detectswhether the DC inputs A and B are operated in parallel.

Module slotsThe inverter is standard-equipped with two module slots. The module slots are located on thecommunication assembly and allow additional modules to be connected (e.g. SMA SensorModule). The modules are available as accessories. The installation of two identical modules is notpermissible.

Secure power supply operationYou can connect an external outlet and a switch to the inverter in order to activate the outlet. Incase of a grid failure, the outlet supplies a load with current from the PV system. When the outlet isactivated via the switch, the load is supplied with current from the PV system. The inverterautomatically regulates the energy supply of the outlet depending on the solar irradiation on the PVsystem. When the outlet is activated and a load is supplied with current from the PV system, theinverter is disconnected from the utility grid and does not feed into the utility grid.



Do not connect loads that require a stable electricity supply to the outlet for securepower supply operationSecure power supply operation must not be used for loads that require a stable electricitysupply. The power available during secure power supply operation depends on the solarirradiation on the PV system. Therefore, power output can fluctuate considerably dependingon the weather or may not be available at all.• Do not connect loads to the outlet for secure power supply operation if they aredependent on a stable electricity supply for reliable operation.

Multifunction relayThe inverter is equipped with a multifunction relay as standard. The multifunction relay is amultifunctional interface that can be configured for the operating mode used by a particular system.

Arc-Fault Circuit Interrupter (AFCI)In accordance with the National Electrical Code®, Article 690.11, the inverter has a system for arcfault detection and interruption.An electric arc with a power of 300 W or greater must be interrupted by the AFCI in the timespecified by UL 1699B. A detected electric arc causes the inverter to interrupt feed-in operation: Inorder to restart feed-in operation, the feed-in operation must be activated manually. If theinstallation conditions allow it, you can deactivate the arc-fault circuit interrupter.

3.3 LED SignalsThe LEDs indicate the operating state of the inverter.

2. To move to the next message, tap on the enclosure lid of the Connection Unit once.

4.2 Activate WPS Function• Tap twice on the enclosure lid of the Connection Unit.☑ The blue LED flashes quickly for approx. two minutes.

4.3 Secure Power Supply Operation

4.3.1 Activating Secure Power Supply OperationIf an outlet and a switch for secure power supply operation are connected to the inverter, you cansupply a load with current from the PV system in case of a grid failure during the day. If youactivate the secure power supply operation, the inverter supplies loads that are connected to theoutlet for secure power supply operation.In case of overload, underload or insufficient solar irradiation, the voltage supply of the outlet isbriefly interrupted. The inverter automatically attempts to reestablish the voltage supply 20 secondsafter the interruption. This can lead to inadvertent starting of the load that is connected to the outlet.Ensure that the load connected to the outlet does not consume too much power. If necessary,reduce the power consumption of the load.

In case of a grid failure during the night, secure power supply operation is notpossibleDuring the night, secure power supply operation cannot be activated since the PV system doesnot produce power that is required to supply the load.• In case of a grid failure during the night, do not activate secure power supply operation.• Continue to operate the inverter on the utility grid and wait for restoration of gridoperation.

• In the event of a persistent grid failure, switch to secure power supply operation aftersunrise.

4 Operation of the InverterSMA Solar Technology America LLC


Do not connect loads that require a stable electricity supply to the outlet for securepower supply operationSecure power supply operation must not be used for loads that require a stable electricitysupply. The power available during secure power supply operation depends on the solarirradiation on the PV system. Therefore, power output can fluctuate considerably dependingon the weather or may not be available at all.• Do not connect loads to the outlet for secure power supply operation if they aredependent on a stable electricity supply for reliable operation.

Procedure:1. If no load is connected to the outlet, connect a load.2. Turn the switch of the outlet to secure power supply operation.3. Wait one minute.☑ The inverter commences secure power supply operation. As soon as the inverter supplies theoutlet with power, the green LED flashes (1.5 s on and 0.5 s off) and the message SPS-modeactive is shown in the display along with the amount of power being supplied from theinverter to the outlet. In addition, the control light of the outlet for secure power supplyoperation glows.

✖ The green LED does not flash and no message that the secure power supply operation mode isactivated appears on the display or the control lamp of the outlet does not glow?The output power of the PV system is too low. Irradiation on the PV system is probably too lowor the connected load requires more power than currently available.• Ensure that the outlet's switch is set to secure power supply operation.• If irradiation is too low, wait for it to increase.• Connect a load with lower power consumption to the outlet.

✖ No voltage can be measured at the outlet?• Ensure that the outlet's switch is set to secure power supply operation.• Ensure that the switch, outlet and control light for secure power supply operation arecorrectly connected.

4.3.2 Deactivating Secure Power Supply Operation1. If necessary, disconnect the load from the outlet.2. Turn the switch of the outlet to grid operation.☑ Grid operation is activated.

8.3 Checking the PV System for Ground Faults

If the inverter displays the event numbers 3501, 3601 or 3701, there could be a ground fault. Theelectrical insulation from the PV system to ground is defective or insufficient.

Danger to life due to electric shockIn the event of a ground fault, high voltages can be present.• Touch the cables of the PV array on the insulation only.• Do not touch any parts of the substructure or frame of the PV array.• Do not connect PV strings with ground faults to the inverter.

Destruction of the measuring device due to overvoltage• Only use measuring devices with a DC input voltage range of 600 V or higher.

Procedure:In order to check the PV system for ground faults, perform the following actions in the prescribedorder. The exact procedure is described in the following sections.• Check the PV system for ground faults by measuring the voltage.• If the voltage measurement was not successful, check the PV system via insulation resistancemeasurement for ground faults.

Test by Measuring the VoltageProceed 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 any voltage sources (see the inverter installation manual).

2. Measure the voltages:• Measure the voltage between the positive terminal and the ground potential (PE).• Measure the voltage between the negative terminal and the ground potential (PE).• Measure the voltage between the positive and negative terminals. If the following results are present at the same time, there is a ground fault in the PVsystem:☑ All measured voltages are stable.☑ The sum of the two voltages to ground potential is approximately equal to thevoltage between the positive and negative terminals.

• If a ground fault is present, determine the location of the ground fault via the ratio of thetwo measured voltages and eliminate the ground fault.

Example: Location of the ground faultThe 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 theinsulation resistance.

4. Reconnect the strings without ground faults to the inverter and recommission the inverter (seeinverter installation inverter).



Test by Measuring the Insulation ResistanceIf the voltage measurement does not provide sufficient evidence of a ground fault, the insulationresistance measurement can provide more exact results.

Figure 4: Schematic diagram of the measurement

Calculating the insulation resistanceThe expected total resistance of the PV system or of an individual string can be calculatedusing the following formula:

total

The exact insulation resistance of a PV module can be obtained from the module manufactureror the datasheet.For the resistance of a PV module an average value can be assumed: for thin-film PV modulesapproximately 40 MOhm and for polycrystalline and monocrystalline PV modulesapproximately 50 MOhm per PV module (for further information on calculating the insulationresistance see the Technical Information "Insulation Resistance (Riso) of Non-GalvanicallyIsolated 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 arrayThe insulation resistance can only be measured with a suitable device for safe disconnectionand short-circuiting of the PV array. If no suitable device is available, the insulationmeasurement 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 any voltage sources (see the inverter installation manual).

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 systemvoltage 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 theoreticallycalculated value, there is a ground fault present in that string.

10. Reconnect to the inverter only those strings from which the ground fault has been eliminated.11. Reconnect all other strings to the inverter.12. Recommission the inverter (see inverter installation manual).13. If the inverter still displays an insulation error, contact the Service (see Section 11 "Contact",page 63). The PV modules might not be suitable for the inverter in the present quantity.

8.4 Resetting the Operation Inhibition after Detection of anArc Fault

If the red LED is glowing and the event number 4301 is shown on the display and/or in the eventlist on the user interface of the inverter, the inverter has detected an electric arc and interrupts feed-in operation.There are two options for resetting the operation inhibition:• Reset the operation inhibition by tapping twice on the enclosure lid of the Connection Unit.• Reset the operation inhibition by parameter setting.

Reset the operation inhibition by tapping twice on the enclosure lid of theConnection Unit1.

Danger to life due to electric shock• Disconnect the inverter from any voltage sources (see the inverter installation manual).

2. Ensure that the PV modules, the connected DC cables and the connecting terminal plate for theDC connection are not defective.Repair or replace defective PV modules, DC cables or connecting terminal plate for the DCconnection.



3. Recommission the inverter (see inverter installation manual).4. If the event with the event number 4301 appears in the display, immediately tap on theenclosure lid twice in quick succession. Here, the operation inhibition can only be reset if theevent is showing in the display when you begin tapping.

☑ This effects resetting of the operation inhibition and the inverter will start feeding in again. Atthe same time, the blue LED can flash rapidly, indicating that there is an active WPS function.The WPS function deactivates automatically after a short period.

Reset the operation inhibition by parameter setting1.

Danger to life due to electric shock• Disconnect the inverter from any voltage sources (see the inverter installation manual).

2. Ensure that the PV modules, the connected DC cables and the connecting terminal plate for theDC connection are not defective.Repair or replace defective PV modules, DC cables or connecting terminal plate for the DCconnection.
