The Windy Boy is suitable for indoor and outdoor use.
Alternative uses of the Windy Boy not expressly recommended by SMA Solar Technology AG are
not permitted.
For safety reasons, it is not permitted to modify the product or install components that are not explicitly
recommended or distributed by SMA Solar Technology AG for this product.

2.2 Safety Precautions
Electric Shock
High voltages are present in the live components of the inverter. Touching these components can
cause fatal electric shocks.
• Do not open the inverter.
• All work on the inverter (e.g. repairs, modifications) must be carried out by skilled persons only.
Burn Hazards
Some parts of the enclosure can become hot during operation.
• During operation, only touch the lower enclosure lid. Do not place any obj ect s on the enc losure ,
as this can lead to yield losses.
Inverter Damage
Overvoltages can destroy the inverter.
• If the display message DC overvoltage ‒ Disconnect generator is shown, inform your
installer IMMEDIATELY.
The inverter can be damaged by removing the ESS under load.
• Always leave the ESS plugged in during operation.

3.4 Bluetooth
The inverter is equipped with a Bluetooth interface as standard and can communicate with special
SMA communication products or other inverters (for information on supported products, see
www.SMA-Solar.com).
If you wish to communicate via Bluetooth, you can protect the inverter with a plant password for the
user.
All inverters are delivered with a default plant password for the user (0000) as standard. To protect
the plant from unauthorised access, you must change the default plant password for the user using
Sunny Explorer (for information on changing the plant password, refer to the Sunny Explorer help).
3.5 Slot for Communication Interface
The inverter can optionally be fitted with an extra communication interface (e.g., RS485).
This communication interface enables the inverter to communicate with special SMA communication
products (for information on supported products, see www.SMA-Solar.com). The communication
interface can either be retrofitted or installed ex works according to a specific order.

SMA Solar Technology AG 3 Product Description
3.6 Slot for Multi-Function Interface
The inverter is equipped with a slot for multi-function interfaces. This slot is designed to connect a
simple multi-function relay, an SMA Power Control Module or a fan retrofit kit. The multi-function
interface can either be retrofitted or installed ex works according to a specific order.
Multi-Function Relay
The multi-function relay can activate and deactivate error messages, for example.
SMA Power Control Module
The SMA Power Control Module enables the inverter to implement grid management and is also
equipped with a multi-function relay.
Fan Retrofit Kit
The fan retrofit kit provides additional cooling of the inverter in th e event of high a mbient tempera tures
and is likewise equipped with a multi-function relay. The fan retrofit kit and the SMA Power Control
Module cannot be operated in parallel.

6 Glossary SMA Solar Technology AG
6 Glossary
Bluetooth
Bluetooth is a radio technology that allows the inverter and other communication products to
communicate with each other. For Bluetooth communication, the Bluetooth devices do not need to be
within sight of each other.
Energy
Energy is the power that a system can supply or consume within a certain time unit. Energy is
measured in Wh (watt hours). If, for instance, your inverter feeds in for half an hour at 3,000 W and
half an hour at 2,000 W, it will have fed a total of 2,500 Wh into the electricity grid.
Power
Power is the product of voltage and electrical current strength. Power is measured in W (watts).
The power shown in the display is an instantaneous value. It indicates the power that your inverter is
currently feeding into the electricity grid.
