User Manual SBxx-US-1XP-41-BA-en-11 17

Page 18

3 Product Overview

SMA Solar Technology AG

A complete PV Rapid Shutdown System consists of the inverter, PV array disconnect switches, and a Rapid Shutdown initiation device. The Rapid Shutdown initiation device serves to initiate a rapid shutdown. The PV Rapid Shutdown System must limit the DC conductors to <30V within 30seconds.

NOTICE - The inverter's Rapid Shutdown function is initiated by disconnecting the inverter from the AC grid voltage, for example, by opening the main PV system AC disconnect. The AC disconnect that serves as the Rapid Shutdown initiation device must be readily accessible and clearly marked in accordance with National Electrical Code®. The Rapid Shutdown status of the PV system will be indicated by the On/Off (Closed/Open) position of this AC disconnect. The Off (Open) position indicates that a rapid shutdown has been initiated.

If PV array disconnect switches compliant with the SunSpec communication signal for Rapid Shutdown systems are installed, the inverter can transmit a SunSpec-compliant "permission to operate" signal to them via its DC input conductors. When a rapid shutdown is initiated, the inverter will stop transmitting the SunSpec signal. When the SunSpec signal is not being received, the PV array disconnect switches are responsible for reducing line voltages within the PV array in accordance with National Electrical Code®. In the event of a rapid shutdown via the SunSpec communication signal, it is important that all PV modules connected to the inverter are always equipped with SunSpec-compliant PV array disconnect switches, otherwise the inverter cannot start feed-in operation. The sum of the standby voltages of all PV array disconnect switches of a string must be <30V to ensure safe discharging of the DC lines. In addition, the recommended total length of all DC lines of a string should not exceed 300m (1000ft). The total length defines the length of the entire string wiring including the connection cable of the PV module switch in the string (measured from the positive DC terminal to the negative DC terminal of the inverter).

A PV Rapid Shutdown system can also be installed using PV array disconnect switches initiated in case of power failures or other means. In these cases, it must be ensured that the PV system Rapid Shutdown initiation device initiates a rapid shutdown of the PV array devices at the same time that the inverter is disconnected from grid voltage.

The PV array disconnect switches must disconnect the PV array from the inverter within a maximum of 15 seconds after Rapid Shutdown initiation.

The inverter is capable of grid support operation where in case of a power failure or by activating the AC disconnect, the inverter remains connected to the utility grid for a defined ride-through time and waits for voltage recovery. If grid voltage does not recover within the defined ride-through time, the inverter disconnects from the grid and a rapid shutdown is initiated.

The Rapid Shutdown function is disabled by default. The Rapid Shutdown function should only be enabled when PV array disconnect switches have been installed within the PV array or between the PV array and the inverter. The Rapid Shutdown function can be enabled during or after inverter commissioning via the user interface by selecting the operating mode suitable for the PV array disconnect switches. If the Rapid Shutdown function is enabled and no PV array disconnect switches are installed, the inverter cannot discharge the connected DC input conductors during a rapid shutdown. As a result, the inverter can be damaged.

3 Product Overview

Parallel Operation of the DC Inputs A and B

The DC inputs A and B of the inverter can be operated in parallel and up to three strings can be connected to it in parallel. As a result, as opposed to normal operation, up to three strings can be connected directly to inverters with two DC inputs and up to four strings to inverters with three DC inputs. The inverter automatically detects the parallel operation of the DC inputs A and B.

Secure power supply operation

You can connect an external outlet and a switch to the inverter in order to enable the outlet. In case of a grid failure, the outlet supplies a load with current from the PV system. When the outlet is enabled via the switch, the load is supplied with current from the PV system. The inverter automatically regulates the energy supply of the outlet depending on the solar irradiation on the PV system. When the outlet is enabled and a load is supplied with current from the PV system, the inverter is disconnected from the utility grid and does not feed into the utility grid.

When using the SMA Rooftop Communication Kit and the TS4-O module technology components, secure power supply operation is only available if an external rapid shutdown initiator and the switch for secure power supply operation are connected to the module of the SMA Rooftop Communication Kit. The switch for secure power supply operation must be connected to the module in series with a voltage supply of 18V (e.g. two 9V batteries). If an external rapid-shutdown initiator is used, the AC miniature circuit breaker is no longer the rapid-shutdown initiator in the system.

When using TS4-F or TS4-S module technology components, secure power supply operation is not available.

No secure power supply operation when using TS4-F and TS4-S module technology components

If the SMARooftopCommunicationKit is installed in the inverter and TS4-F and TS4-S module technology components are used in the system, the secure power supply operation is not available. Secure power supply operation is only available in connection with TS4-O module technology components.

No secure power supply operation when using PV array disconnect switch as per the SunSpec interoperability specification

The secure power supply operation is not available if the Rapid Shutdown function of the inverter is enabled and the PV array disconnect switches are used in accordance with the SunSpec Interoperability Specification.

3 Product Overview

SMA Solar Technology AG

Do not connect loads that require a stable electricity supply to the outlet for secure power supply operation.

Secure power supply operation must not be used for loads that require a stable electricity supply. The power available during secure power supply operation depends on the solar irradiation on the PV system. Therefore, power output can fluctuate considerably depending on the weather or may not be available at all.

• Do not connect loads to the outlet for secure power supply operation if they are dependent on a stable electricity supply for reliable operation.

Multifunction Relay

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

SMA ShadeFix

The inverter is equipped with the shade management system SMA ShadeFix. SMA ShadeFix uses an intelligent MPP tracking system to determine the operating point with the highest output during shading conditions. With SMA ShadeFix, inverters use the best possible energy supply from the PV modules at all times to increase yields in shaded systems. SMA ShadeFix is enabled by default. The time interval of SMA ShadeFix is usually six minutes. This means that the inverter determines the optimum operating point every six minutes. Depending on the PV system or shading situation, it may be useful to adjust the time interval.

String-failure detection

The self-learning string failure detection identifies to which of the three inverter DC inputs the strings are connected. The self-learning string failure detection identifies if the connected string is inoperable and is no longer contributing to the energy yield (e.g. due to damages such as a cable break) and monitors the input to which the defective string is connected. If the error persists, an event will be reported at the latest one day after the detection of the defective string. This prevents partial failures of the PV array from being undetected for a long time and which will result in yield losses. The self-learning string failure detections automatically identifies if a string has been repaired and resets the event. If the defective string should no longer be connected, the event must be reset manually.

Arc-Fault Circuit Interrupter (AFCI)

In accordance with the National Electrical Code®, the inverter has a system for DC arc fault detection and interruption. The arc-fault circuit interrupter is listed in accordance with UL 1699B Ed.1. A detected electric arc causes the inverter to interrupt feed-in operation for a short time and to resume the feed-in operation automatically. If the installation conditions allow it, you can deactivate the arc-fault circuit interrupter.

SMA Smart Connected

SMA Smart Connected is the free monitoring of the inverter via the SMA SunnyPortal. Thanks to SMA Smart Connected, the PV system operator and qualified person will be informed automatically and proactively about inverter events that occur.

User ManualSBxx-US-1XP-41-BA-en-1120

4.8 Secure power supply operation

4.8.1 Enable secure power supply operation

If an outlet and a switch for secure power supply operation are connected to the inverter, you can supply a load with current from the PV system in case of a grid failure during the day. If you enable the secure power supply operation, the inverter supplies loads that are connected to the outlet for secure power supply operation.

In case of overload, underload or insufficient solar irradiation, the voltage supply of the outlet is briefly interrupted. The inverter automatically attempts to reestablish the voltage supply 20seconds after 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 not possible.

During the night, secure power supply operation cannot be enabled since the PV system does not produce power that is required to supply the load.

• In case of a grid failure during the night, do not enable secure power supply operation.

• Continue to operate the inverter on the utility grid and wait for restoration of grid operation.

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

Do not connect loads that require a stable electricity supply to the outlet for secure power supply operation.

• Do not connect loads to the outlet for secure power supply operation if they are dependent 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

the outlet with power, the green LED flashes (1.5s on and 0.5s off) and the message SPS-mode active is shown in the display along with the amount of power being supplied from the inverter to the outlet. In addition, the control light of the outlet for secure power supply operation glows.

Page 36

4 Operation

4. The PV system's output is too low when: the green LED does not flash and no message that the

secure power supply operation mode is enabled appears on the display or the control lamp of the outlet does not glow. Irradiation on the PV system is probably too low or the connected load requires more power than currently available. Carry out the following measures:

• 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.

5. If no voltage can be measured at the outlet, ensure that the switch of the outlet is set to secure

power supply operation, and that the switch, outlet and control light for secure power supply operation are correctly connected.

4.8.2 Disable secure power supply operation

1. If necessary, disconnect the load from the outlet.

2. Turn the switch of the outlet to grid operation. ☑ Grid operation is activated.

3. Switch on the circuit breaker of the PV system.

☑ The inverter connects to the utility grid and starts feed-in operation.

In doing so, you can switch the WLAN direct connection and the WLAN connection in the local network on independently of each other.

Switching on the WLAN function only possible via Ethernet connection

If you switch off both the WLAN function for the direct connection and for the connection in the local network, access to the inverter user interface and therefore reactivation of the WLAN interface is only possible via an Ethernet connection.

The basic procedure for changing operating parameters is explained in another section (see Section4.13 "Changing Operating Parameters", page38).

Switching WLAN Off

If you would like to switch the WLAN function off completely, you must switch off both the direct connection and the connection in the local network.

Procedure:

• To switch off the direct connection in the parameter group PV system communication > WLAN, select the parameter Soft-access-point is turned on and set this to No.

• To switch off the connection in the local network in the parameter group PV system communication > WLAN, select the parameter WLAN is turned on and set this to No.

Switching WLAN On

If you have switched the WLAN function for direct connection or for connection in the local network off, you can switch the WLAN function back on in accordance with the following procedure.

Requirement:

☐ If the WLAN function was previously switched off completely, the inverter must be connected

to a computer or router via Ethernet.

Procedure:

• To switch on the WLAN direct connection, in the parameter group PV system communication > WLAN, select the parameter Soft-access-point is turned on and set this

to Yes.

6.3 Checking the PV System for Ground Faults

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

DANGER

Danger to life due to electric shock when touching live system components in case of a ground fault

If a ground fault occurs, parts of the system may still be live. Touching live parts and cables results in death or lethal injuries due to electric shock.

• Disconnect the product from voltage sources and make sure it cannot be reconnected before working on the device.

• 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.

• Ensure that no voltage is present and wait five minutes before touching any parts of the PV system or the product.

WARNING

Danger to life due to electric shock from destruction of the measuring device due to overvoltage

• Only use measuring devices with a DC input voltage range of 600V or higher.

User Manual SBxx-US-1XP-41-BA-en-11 67

Page 68

6 Troubleshooting

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 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 resistance measurement for ground faults.

SMA Solar Technology AG

Test by Measuring the Voltage

Proceed as follows to check each string in the PV system for ground faults.

Procedure:

DANGER

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 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.

3. 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.

4. If a definite ground fault cannot be measured and the message is still displayed, measure the insulation resistance.

5. Reconnect the strings without ground faults to the inverter and recommission the inverter (see inverter installation inverter).

SMA Solar Technology AG

Calculating the insulation resistance

The expected total resistance of the PV system or of an individual string can be calculated using the following formula:

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.

DANGER

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 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 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.
