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.
The product must only be operated with PV modules
of protection class II in accordance with IEC 61730,
application class A. The PV modules must be
compatible with this product.
The product is not equipped with an integrated
transformer and therefore has no galvanic isolation.
The product must not be operated with PV modules
whose outputs are grounded. This can cause the
product to be destroyed. The product may be
operated with PV modules whose frame is
grounded.
PV modules with a high capacity to ground must
only be used if their coupling capacity does not
exceed 900 nF (for information on how to determine
the coupling capacity, see the Technical Information
"Leading Leakage Currents" at www.SMA-
Solar.com).
All components must remain within their permitted
operating ranges and their installation requirements
at all times.
The product must only be used in countries for which
it is approved or released by SMA Solar
Technology AG and the grid operator.
Use SMA products only in accordance with the
information provided in the enclosed documentation
and with the locally applicable laws, regulations,
standards and directives. Any other application may
cause personal injury or property damage.

2.2 IMPORTANT SAFETY
INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This section contains safety information that must be
observed at all times when working.
The product has been designed and tested in
accordance with international safety requirements.
As with all electrical or electronical devices, there
are residual risks despite careful construction. To
prevent personal injury and property damage and
to ensure long-term operation of the product, read
this section carefully and observe all safety
information at all times.
DANGER
Danger to life due to electric shock
when live components or DC cables are
touched
When exposed to light, the PV modules generate
high DC voltage which is present in the DC cables.
Touching live DC cables results in death or lethal
injuries due to electric shock.
• Do not touch non-insulated parts or cables.
• Disconnect the product from voltage sources
and make sure it cannot be reconnected
before working on the device.
• Do not disconnect the DC connectors under
load.
• Wear suitable personal protective equipment
for all work on the product.
