Operating manual SBxx-1AV-41-BE-en-10 15 4 Product Overview SMA Solar Technology AG Depending on the requirements of the grid operator, you can activate and configure the functions (e.g. active power limitation) via operating parameters. Parallel Operation of the DC Inputs A and B You have the option of operating the inverter DC inputs A and B in parallel. As a result, and as opposed to normal operation, several parallel-connected strings can be connected to the inverter. The inverter automatically detects the parallel operation of the DC inputs A and B. SMA OptiTrac Global Peak SMA OptiTrac Global Peak is an advancement of SMA OptiTrac and allows the operating point of the inverter to follow the optimal operating point of the PV array (MPP) precisely at all times. In addition, with the aid of SMA OptiTrac Global Peak, the inverter detects several maximum power points in the available operating range, such as may occur particularly with partially shaded strings. SMA OptiTrac Global Peak is enabled by default. All-pole sensitive residual-current monitoring unit The all-pole sensitive residual-current monitoring unit detects alternating and direct differential currents. In single-phase and three-phase inverters, the integrated differential current sensor detects the current difference between the neutral conductor and the line conductor(s). If the current difference increases suddenly, the inverter disconnects from the utility grid. 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. SMA Smart Connected is activated during registration in Sunny Portal. In order to use SMA Smart Connected, it is necessary that the inverter is permanently connected to Sunny Portal and the data of the PV system operator and qualified person is stored in Sunny Portal and up-to-date. 4.4 LED Signals The LEDs indicate the operating state of the inverter.

The requirements for the minimum wire size derive from these directives. Examples of factors influencing cable dimensioning are: nominal AC current, type of cable, routing method, cable bundling, ambient temperature and maximum desired line losses (for calculation of line losses, see the design software "Sunny Design" from software version 2.0 at www.SMA-Solar.com). 22 SBxx-1AV-41-BE-en-10 Operating manual SMA Solar Technology AG 6 Electrical Connection Load-break switch and cable protection: NOTICE Damage to the inverter due to the use of screw-type fuses as load-break switches Screw-type fuses (e.g. DIAZED fuse or NEOZED fuse) are not load-break switches. · Do not use screw-type fuses as load-break switches. · Use a load-break switch or circuit breaker as a load disconnection unit (for information and design examples, see the Technical Information "Circuit Breaker" at www.SMA-Solar.com). In PV systems with multiple inverters, protect each inverter with a separate circuit breaker. Make sure to observe the maximum permissible fuse protection (see Section 13 "Technical Data", page 88). This will prevent residual voltage from being present at the corresponding cable after disconnection. Loads installed between the inverter and the circuit breaker must be fused separately. Residual-current monitoring unit: If an external residual-current device is required, install a residual-current device which trips at a residual current of 100 mA or higher (for details on selecting a residual-current device, see the Technical Information "Criteria for Selecting a Residual-Current Device" at www.SMASolar.com). Overvoltage category: The inverter can be used in grids of overvoltage category III or lower in accordance with IEC 60664-1. That means that the inverter can be permanently connected to the grid-connection point of a building. In case of installations with long outdoor cabling routes, additional measures to reduce overvoltage category IV to overvoltage category III are required (see the Technical Information "Overvoltage Protection" at www.SMA-Solar.com). Grounding conductor monitoring: The inverter is equipped with a grounding conductor monitoring device. This grounding conductor monitoring device detects when there is no grounding conductor connected and disconnects the inverter from the utility grid if this is the case. Depending on the installation site and grid configuration, it may be advisable to deactivate the grounding conductor monitoring. This is necessary, for example, in an IT system if there is no neutral conductor present and you intend to install the inverter between two line conductors. If you are uncertain about this, contact your grid operator or SMA Solar Technology AG. · Grounding conductor monitoring must be deactivated after initial start-up depending on the grid configuration (see Section 8.15, page 59). Operating manual SBxx-1AV-41-BE-en-10 23 6 Electrical Connection SMA Solar Technology AG Safety in accordance with IEC 62109 when the grounding conductor monitoring is deactivated In order to guarantee safety in accordance with IEC 62109 when the grounding conductor monitoring is deactivated, you have to connect an additional grounding conductor to the inverter. · Connect an additional grounding conductor that has an cross-section of at least 10 mm (see Section 6.2.3, page 25). This prevents touch current in the event of the grounding conductor on the AC connector bush insert failing. Connection of an additional grounding conductor In some countries, an additional grounding conductor is generally required. In each case, observe the locally applicable regulations. · If an additional grounding conductor is required, connect the one that has an crosssection of at least 10 mm (see Section 6.2.3, page 25). This prevents touch current in the event of the grounding conductor on the AC connector bush insert failing. 6.2.2 Connecting the Inverter to the Utility Grid Requirements: The AC and DC electric circuits are isolated from the enclosure. If required by the National Electrical Code® ANSI/NFPA 70 or Canadian Electrical Code® CSA C22.1, the installer is responsible for grounding the system. The connection requirements of the grid operator must be met. The grid voltage must be within the permissible range. The exact operating range of the inverter is specified in the operating parameters. Procedure: 1. Disconnect the circuit breaker and secure it against reconnection. 2. Dismantle the AC cable by 50 mm. 3. Shorten L1, L2, L3 and N by 8 mm each so that the grounding conductor is 8 mm longer. This ensures that the grounding conductor is the last to be pulled from the screw terminal in the event of tensile strain. 4. Strip the insulation of L1, L2, L3, N and the grounding conductor by 12 mm. 5. In the case of fine stranded wire, L1, L2, L3, N and the grounding conductor are to be fitted with bootlace ferrules. 6. Assemble the AC connector and connect the conductor to the AC connector (see manual of the AC connector). 7. Ensure that all conductors are securely connected to the AC connector. 24 SBxx-1AV-41-BE-en-10 Operating manual SMA Solar Technology AG 8. Plug the AC connector into the jack for the AC connection. When doing so, align the AC connector so that the key on the inverter AC jack is inserted into the keyway on the AC connector bush insert. 6 Electrical Connection 6.2.3 Connecting Additional Grounding If additional grounding or equipotential bonding is required locally, you can connect additional grounding to the inverter. This prevents touch current if the grounding conductor on the AC connector fails. The necessary ring terminal lug and the screw are included in the scope of delivery of the inverter. Additionally required material (not included in the scope of delivery): 1 grounding cable Cable requirements: Use of fine-stranded conductors You can use an inflexible or a flexible, fine-stranded conductor. · When using a fine-stranded conductor, it has to be double crimped by a ring terminal lug. Make sure that no insulated conductor is visible when pulling or bending. This will ensure sufficient strain relief by means of the ring terminal lug. Grounding cable cross-section: max. 10 mm² Procedure: 1. Strip the grounding cable insulation. 2. Insert the stripped part of the grounding cable into the ring terminal lug and crimp using a crimping tool. Operating manual SBxx-1AV-41-BE-en-10 25 6 Electrical Connection 3.

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. NOTICE Destruction of the measuring device due to overvoltage · Only use measuring devices with a DC input voltage range of 1000 V or higher. 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. Test by Measuring the Voltage Proceed as follows to check each string in the PV system for ground faults. Procedure: 1. DANGER Danger to life due to high voltages · Disconnect the inverter from all voltage sources (see Section 9, page 61). 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). Operating manual SBxx-1AV-41-BE-en-10 81 11 Troubleshooting SMA Solar Technology AG · 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). Location of the ground fault The example shows a ground fault between the second and third PV module.

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 Danger to life due to high voltages · Disconnect the inverter from all voltage sources (see Section 9, page 61). Operating manual SBxx-1AV-41-BE-en-10 83 11 Troubleshooting SMA Solar Technology AG 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. 12. Recommission the inverter. 13. If the inverter still displays an insulation error, contact the Service (see Section 14, page 94). The PV modules might not be suitable for the inverter in the present quantity. 84 SBxx-1AV-41-BE-en-10 Operating manual SMA Solar Technology AG 12 Decommissioning the Inverter 12 Decommissioning the Inverter To decommission the inverter completely upon completion of its service life, proceed as described in this Section.
