2 SafetyENGLISHSMA Solar Technology America LLC2 Safety2.1Intended UseThe Sunny Boy is a transformerless PV inverter with three MPP trackers, which converts the directcurrent of the PV array into grid-compliant alternating current and feeds it into the utility grid.The product is suitable for indoor and outdoor use.All components must remain within their permitted operating ranges at all times.The product must only be operated with PV arrays (PV modules and cabling) that are approved bythe electrical standards applicable on-site and the National Electrical Code ANSI/NFPA 70 orthe Canadian Electrical Code CSA C22.1.No galvanic isolationThe product is not equipped with a transformer and therefore has no galvanic isolation. Do not operate grounded PV modules together with the product. If grounded PVmodules are connected to the product, an event will occur which will appear on theproduct display. The event will also be displayed, along with the associated message, inthe event list on the user interface of the product. Only ground the mounting frames of the PV modules. The neutral conductor of the AC output is not bonded to ground within the product. The neutral conductor of the AC output for secure power supply operation is bonded toground within the product.PV modules with a high capacity to ground may only be used if their coupling capacity does notexceed 2.5 μF.To protect the PV system against excessive reverse currents under fault conditions, the NationalElectrical Code , Section 690.9, requires overcurrent protection for PV source circuits wherepossible short-circuit currents exceed the ampacity of source circuit conductors or the maximumseries fuse rating of the PV modules. Typically, this requires string fusing where more than twostrings are combined in parallel. Where overcurrent protection is required, National ElectricalCode , Section 690.35, requires that both positive and negative conductors have overcurrentprotection for ungrounded PV arrays.The product must only be used in countries for which it is approved or released by SMA and thegrid operator.Use this product only in accordance with the information provided in the enclosed documentationand with the locally applicable standards and directives.

The inverter is delivered with theWLAN interface activated as standard. If you do not want to use WLAN, you can deactivate theWLAN interface.In addition, the inverter has a WPS (WiFi Protected Setup) function. The WPS function is forautomatically connecting the inverter to a device in the same network as the inverter (e.g. router,computer, tablet PC or smartphone).Expanding the radio range in the WLAN networkIn order to expand the radio range of the inverter in the WLAN network, you can install theAntenna Extension Kit accessory set in the inverter.ModbusThe inverter is equipped with a Modbus interface. The Modbus interface is deactivated by defaultand must be configured as needed.The Modbus interface of the supported SMA devices is designed for industrial use and has thefollowing tasks: Remote query of measured values Remote setting of operating parameters Setpoint specifications for system control4-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.16SB5.0-6.0-1SP-US-40-IA-xx-10Installation manual

4 Product DescriptionDo 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.4.3LED SignalsThe LEDs indicate the operating state of the inverter.Installation manualSB5.0-6.0-1SP-US-40-IA-xx-1017ENGLISHSMA Solar Technology America LLC
