2.1 Intended Use
The SunnyBoy is a transformerless PV inverter with three MPP trackers, which converts the direct
current 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 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.

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
4-String-Operation
The "4-String-Operation" function allows the DC inputs A and B of the inverter to operate in parallel
and up to three strings to be connected to it in parallel. As a result, as opposed to normal
operation, up to four strings can be connected to the inverter. The inverter automatically detects
whether the DC inputs A and B are operated in parallel.
Module slots
The inverter is standard-equipped with two module slots. The module slots are located on the

User ManualSB5.0-6.0-1SP-US-40-BA-en-1014
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)

4.3 Secure Power Supply Operation
4.3.1 Activating 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
activate 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 20seconds
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 activated 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 activate 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.

SMA Solar Technology America LLC
User Manual 17SB5.0-6.0-1SP-US-40-BA-en-10
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.
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 (1.5s on and 0.5s 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.
✖ The green LED does not flash and no message that the secure power supply operation mode is
activated appears on the display or the control lamp of the outlet does not glow?

network: 192.168.12.3
Importing and exporting files with end devices having an iOS operating system is
not possible.
For technical reasons, importing and exporting files (e.g. importing an inverter configuration,
saving the current inverter configuration or exporting events) is not possible with mobile end
devices having an iOS operating system.
• Use an end device that does not have an iOS operating system for importing and
exporting files.
The procedure can be different depending on the terminal devices used (e.g. computer, tablet PC
or smartphone). If the procedure described does not apply to your device, establish the direct
connection via WLAN as described in the manual of your device.
Procedure:
1. If your computer, tablet PC or smartphone has a WPS function:
• Activate the WPS function on the inverter. To do this, tap twice on the enclosure lid of the
