2 Safety
2.1 Intended Use
The Sunny Boy is a transformerless PV inverter which converts the direct current of the PV array to
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 by
the electrical standards applicable on-site and the NationalElectricalCode® ANSI/NFPA 70 or
the CanadianElectricalCode® CSA C22.1.
No galvanic isolation
The 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 PV
modules are connected to the product, an event will occur which will appear on the
product display. The event will also be displayed, along with the associated message, in
the 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 to
ground within the product.
PV modules with a high capacity to ground may only be used if their coupling capacity does not
exceed 2.5 μF.
To protect the PV system against excessive reverse currents under fault conditions, the National
Electrical Code®, Section 690.9, requires overcurrent protection for PV source circuits where
possible short-circuit currents exceed the ampacity of source circuit conductors or the maximum
series fuse rating of the PV modules. Typically, this requires string fusing where more than two
strings are combined in parallel. Where overcurrent protection is required, National Electrical
Code®, Section 690.35, requires that both positive and negative conductors have overcurrent
protection for ungrounded PV arrays.
The product must only be used in countries for which it is approved or released by SMA and the
grid operator.

ENGLISH

SMA Webconnect
The inverter is equipped with a Webconnect function as standard. The Webconnect function
enables direct data transmission between the inverters of a small-scale system and the Internet
portal SunnyPortal without any additional communication device and for a maximum of 4 inverters
per SunnyPortal system. In large-scale PV power plants with more than 4 inverters, there is the
option of establishing data transmission between the inverters and the SunnyPortal web-based
monitoring platform via the SMAClusterController or to distribute the inverters over several plants
in the SunnyPortal. If there is an existing WLAN or Ethernet connection, you can directly access
your Sunny Portal system via the web browser on the computer, tablet PC or smartphone.
WLAN
The inverter is equipped with a WLAN interface as standard. The inverter is delivered with the
WLAN interface activated as standard. If you do not want to use WLAN, you can deactivate the
WLAN interface.
In addition, the inverter has a WPS (WiFi Protected Setup) function. The WPS function is for
automatically 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 network
In order to expand the radio range of the inverter in the WLAN network, you can install the
Antenna Extension Kit accessory set in the inverter.
Modbus
The inverter is equipped with a Modbus interface. The Modbus interface is deactivated by default
and must be configured as needed.
The Modbus interface of the supported SMA devices is designed for industrial use and has the
following tasks:
• Remote query of measured values
• Remote setting of operating parameters
• Setpoint specifications for system control
Parallel Operation of the DC Inputs A and B

Module). The modules are available as accessories. The installation of two identical modules is not
permissible.
4 Product Description SMA Solar Technology America LLC
Installation ManualSB30-77-1SP-US-40-IA-xx-1316
ENGLISH

Secure power supply operation
You can connect an external outlet and a switch to the inverter in order to activate the outlet. In
case of a grid failure, the outlet supplies a load with current from the PV system. When the outlet is
activated 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 activated 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.
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 a
multifunctional 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 arc
fault detection and interruption.
An electric arc with a power of 300W or greater must be interrupted by the AFCI in the time
specified by UL 1699B. A detected electric arc causes the inverter to interrupt feed-in operation: In
order to restart feed-in operation, the feed-in operation must be activated manually. If the
installation conditions allow it, you can deactivate the arc-fault circuit interrupter.
4.3 LED Signals
The LEDs indicate the operating state of the inverter.

5 Mounting
5.1 Requirements for Mounting
Requirements for the mounting location:
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires.
• Do not mount the inverter in areas containing highly flammable materials or gases.
• Do not mount the inverter in a potentially explosive atmosphere.
☐ The inverter must be mounted on a solid support surface (e.g. concrete, brickwork, suitable
constructions). When mounted on drywall or similar materials, the inverter emits audible
vibrations during operation which could be perceived as annoying.
☐ The inverter can be mounted in a position that is directly exposed to solar irradiation. Direct
solar irradiation can cause the inverter to overheat. As a result, the inverter reduces its power
output.
☐ The DC load-break switch of the inverter must always be freely accessible.
☐ The mounting location must be suitable for the weight and dimensions of the inverter (see
Section10 "Technical Data", page60).
☐ To ensure optimum operation, the ambient temperature should be between -25°C (-13°F) and
+45°C (113°F).
☐ Climatic conditions must be met (see Section10 "Technical Data", page60).
☐ The mounting location should be freely and safely accessible at all times without the need for
any auxiliary equipment (such as scaffolding or lifting platforms). Non-fulfillment of these
criteria may restrict servicing.
