2.1 Intended Use
The Antenna Extension Kit is an accessory set for SMA inverters: By installing the Antenna Extension Kit in an SMA
inverter with WLAN interface, the inverter's radio range can be optimized within the WLAN network.
The Antenna Extension Kit must only be installed in the following SMA inverters:
• STP 50-40 (Sunny Tripower CORE1)
The inverter still complies with the standard after the product has been installed.
The product must only be used in countries for which it is approved or released by SMA Solar Technology AG and the
grid operator.
The product is suitable for indoor and outdoor use.
Use this product only in accordance with the information provided in the enclosed documentation and with the locally
applicable standards and directives. Any other application may cause personal injury or property damage.
Alterations to the product, e.g. changes or modifications, are only permitted with the express written permission of
SMA Solar Technology AG. Unauthorized alterations will void guarantee and warranty claims and in most cases
terminate the operating license. SMA Solar Technology AG shall not be held liable for any damage caused by such
changes.
Any use of the product other than that described in the Intended Use section does not qualify as the intended use.
The enclosed documentation is an integral part of this product. Keep the documentation in a convenient place for
future reference and observe all instructions contained therein.
2.2 Safety Information
This section contains safety information that must be observed at all times when working on or with the product.
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 to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage, which is present in the DC conductors
and the live components of the inverter. Touching the DC conductors or the live components can lead to lethal
electric shocks.
• Prior to performing any work on the inverter, always disconnect the inverter from voltage sources on the AC and
DC sides as described in the inverter manual. When doing so, note that even if the DC load-break is switched
off, there will be dangerous direct voltage present in the DC conductors of the inverter.
Danger to life due to electric shock from touching an ungrounded product
Touching an ungrounded product can cause a lethal electric shock.
• Ensure that the product is integrated in the existing overvoltage protection.
2Safety SMA Solar Technology AG
Installation ManualEXTANT-40-IA-en-106
Increased electromagnetic radiation through the antenna
During operation, the antenna produces an electromagnetic field and can interfere with other devices (e.g.,
pacemakers) due to electromagnetic interference.
• Persons must not remain closer than 20 cm to the antenna for long periods of time.
Damage to the inverter or product due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter or the product through electrostatic
discharge.
• Ground yourself before touching any component.

4 Mounting
SMA Solar Technology AG
Installation Manual 9EXTANT-40-IA-en-10
The mounting location of the antenna is crucial for the quality of the wireless connection. Radio waves are emitted in
circles from the longitudinal side of the antenna. A circular dead spot begins at the tip of the antenna. If you place the
receiver in this dead spot, the receiver cannot receive any radio waves from the antenna.
Figure 3: Radio waves emitting from the antenna
Position Explanation
A Dead spot
Requirements for the mounting location:
☐ An antenna cable length of 3m (9.8ft) must be observed. The antenna cable must not be extended.
☐ The antenna cable must be placed in such a way that the minimum bending radius of 35mm (1.38in) is
maintained.
☐ The receiver must not be in the dead spot of the antenna.
4.2 Mounting the Antenna
Procedure:

Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage, which is present in the DC conductors
and the live components of the inverter. Touching the DC conductors or the live components can lead to lethal
electric shocks.
• Prior to performing any work on the inverter, always disconnect the inverter from voltage sources on the AC
and DC sides as described in the inverter manual. When doing so, note that even if the DC load-break is
switched off, there will be dangerous direct voltage present in the DC conductors of the inverter.
