2 Safety
2.1 Appropriate Usage
The Sunny Boy is a solar inverter that converts the DC current of the PV array into an AC current and
feeds it into the grid.
Refer to the inverter installation guide for detailed information about the product and its intended use.
The limit values specified in the installation guide of the respective inverter must be strictly adhered to.
The inverter may only be operated with PV arrays (modules and cabling) that have protective
insulation. Do not connect any power sources other than PV modules to the inverter.
Do not use the inverter for purposes other than those described here. Alternative uses, modifications
to the inverter or the installation of components not expressly recommended or sold by the
manufacturer void the warranty claims and operating permission.
Contact the SMA Serviceline if you need clarification regarding proper use of the inverter.
Principle of the string inverter
The string inverter connects solar modules that are connected in series (strings) to the power
distribution grid. Thus, even large PV arrays can be set up using multiple individual strings, each
having its own respective string inverter.

2.3 Identifying the Product
You can identify the inverter by the type plate. The type
plate is on the right side of the enclosure.
The type plate specifies among other things the device
type (Type / Model), the serial number (Serial No.) and
device-specific key data of the product.

SMA America, LLC Operating Modes
User Manual HF_STP_US-BUS095110 13
3 Operating Modes
The inverter indicates various operating conditions with the help of 3 LEDs on the enclosure lid. The
equipment must be connected to a DC power supply. Furthermore the equipment must be connected
to the grid on the AC side to be able to indicate its operational state via display and integrated LEDs.
There must be adequate solar radiation for the inverter to receive the necessary DC voltage.
The following section contains a detailed description of various LED displays and inverter operating
states.
LED Description
AGreen LED
LED lit: Inverter in normal operating mode
LED flashing: Inverter waiting for adequate solar radiation
BRed LED
LED lit: Fault in the inverter. Note the serial number of the inverter and the fault
number and contact your installer. The fault number is indicated on the inverter
display unit.
CBlue LED
LED lit: Inverter is connected to a Bluetooth network and can communicate with
other devices having the same NetID.
LED display
In case you do not have any communication devices available, monitor the LEDs of the
inverter and graphic display regularly at various times during the day and under varying
conditions of solar radiation, particularly in the first year after installation. Thus, you can
detect any potential faults in the system in a timely manner.

Operating Modes SMA America, LLC
14 HF_STP_US-BUS095110 User Manual
3.1 LED Displays
3.1.1 All LEDs are off
Overnight shutdown
The DC voltage on the inverter is too low for grid feeding.
If this operating state occurs during the day with proper
solar radiation, have your installer check the DC voltage.
3.1.2 Green LED is flashing
Startup
The DC voltage is adequate for the inverter to be
calibrated. However, the DC voltage is not adequate for
feeding operation of the inverter.
Usually, inverter calibration requires less than 10
seconds. Thereafter, the inverter commences normal
feeding operation.
3.1.3 Green LED is continuously lit
Feeding operation
The inverter is operating normally and is feeding power
to the power distribution grid.
