2.1 Intended Use

The Sunny Boy is a transformerless PV inverter which converts the direct current of a PV array into
grid-compliant alternating current and feeds it into the utility grid.
The inverter can be installed in the following grid configurations:

• 208Y/120 VAC Wye
• 120/240 VAC Split phase

The inverter is transformerless and has no galvanic isolation. Therefore, the inverter may only be
operated with ungrounded PV arrays. Furthermore, the PV array must be installed in accordance with
the

National Electrical Code

®

, Article 690.35 "Ungrounded Photovoltaic Power Systems" and the

locally valid regulations for ungrounded PV arrays. Additionally, the PV array (PV modules and
cabling) must have protective insulation and the PV modules used must be suitable for use with this
inverter. PV modules with a high capacity to ground may only be used if their coupling capacity does
not exceed 1,400 nF (for information on how to calculate the coupling capacity, see Technical
Information "Capacitive Leakage Currents" at www.SMA-Solar.com).
All components must remain within their permitted operating ranges at all times.
The inverter is suitable for indoor and outdoor use.

• Do not mount the inverter on flammable construction materials.
• Do not mount the inverter in areas where highly flammable materials are stored.
• Do not mount the inverter in areas having a potentially explosive atmosphere.

Only use this product in accordance with the enclosed documentation and with the local standards
and directives. Any other use may cause injury to persons or property damage. For safety reasons,
it is forbidden to modify the product or install components that are not explicitly recommended for this
product or distributed by SMA.
The enclosed documentation is an integral part of this product.

• Read and adhere to the documentation.
• Keep the documentation in a convenient place for future reference.

Radio Frequency Exposure

The inverter can be fitted with a ZigBee

®

wireless interface. If this is the case, do not remain

within 8 in. (20 cm) of the inverter for any length of time.
