2 Basic Information on Radio Transfer
The radio range of the antenna for the Sunny Beam in buildings is 30 m and up to 100 m in the
open air. The ambient conditions and the distance from the Sunny Beam to the antenna are the
critical factors for the radio range. The greater the absorbing qualities of walls, doors etc., the lower
the range.
If the ideal location of the inverter relative to the Sunny Beam, you can bridge walls or ceilings etc.
using the external antenna kit.

2.1 Antenna on Inverter

Standard case from storey to storey
If you installed your inverter e.g. in the attic of your building, ensure that the Sunny Beam is not in
the dead spot directly below the inverter in the building. If you still have poor reception in the
building, you can use the external antenna kit to bridge ceilings or walls, as described in chapter
"External Antenna Kit" on page 32.
