8.4 Radio connection to insolation / temperature measuring instrument BENNING SUN 2
The BENNING PV 3 is able to receive the measured values (insolation, PV module / ambient temperature
and date / time stamp) of the insolation and temperature measuring instrument BENNING SUN 2 (optional)
via radio connection.
For this purpose, the BENNING PV 3 has to be coupled with the BENNING SUN 2 once.
Typical radio range of the BENNING SUN 2 in open space: approx. 30 m
Buildings / metal structures or interfering signals can reduce the radio range.
