11 Troubleshooting SMA Solar Technology AG
26 BTPB-Ant-IEN111510 Installation Guide
The connection between the
inverter with the Bluetooth
Piggy-Back and the
communication product is
disturbed. The distance between the
inverter with Bluetooth Piggy-
Back and the communication
product is too large. • Decrease the distance
between the inverter with
Bluetooth Piggy-Back and the
communication product.
• If required, use an SMA
Bluetooth Repeater to cover
the dead zones.
The Bluetooth radio waves are
being weakened by obstacles
(e.g., walls, ceilings, doors). • Position the communication
product in such a manner as to
prevent obstacles from
disturbing the Bluetooth radio
waves.
• If required, use an SMA
Bluetooth Repeater to cover
the dead zones.
The distance between the
inverter with Bluetooth Piggy-
Back and other devices using
the 2.4 GHz frequency band is
too small. • Make sure that the
requirements for the installation
site of the inverter with
Bluetooth Piggy-Back are met
(see section 7.1).
The antenna has not been
connected correctly to the
Bluetooth Piggy-Back.
• Ensure that the antenna is
screwed onto the antenna
cable correctly (see section
7.3).
• Ensure that the antenna cable
plug is correctly screwed onto
the antenna connection of the
Bluetooth Piggy-Back (see
section 7.3).
The Bluetooth Piggy-Back
firmware cannot be
updated. The inverter's feed-in power is
less than 50 W. • Only update the firmware if the
feed-in power is at least 50 W.
