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.

Position Designation
A Type label
The type label uniquely identifies the inverter. You will require the information
on the type label to use the product safely and when seeking customer sup-
port from the SMA Service Line. You will find the following information on the
type label:
• Device type (Model)
• Serial number (Serial No.)
• Date of manufacture
• Device-specific characteristics
B LEDs
The LEDs indicate the operating state of the inverter (see Section 9.2 "LED Sig-
nals", page 44).
C Electronic Solar Switch (ESS)*
The ESS and the DC connectors together form a DC load-break switch. When
plugged in, the ESS forms a conductive path between the PV array and the in-
verter. Removing the ESS interrupts the DC electric circuit and removing all DC
connectors disconnects the PV array completely from the inverter.
D Display
The display shows the current operating data and errors.
E Enclosure lid
* Optional
