ireless signal environmental checks
The WLAN board of the inverter uses radio waves to transmit and re-
ceive data, it is therefore important to assess this factor in order to have
optimal installation.
• Walls in reinforced cement and surfaces covered in metal (doors,
shutters, etc.) can markedly reduce the reach of the device which
even in optimal conditions, should be of approximately 50 metres in
free space.
• It is therefore recommended that before installing the inverter, the
strength of the wireless signal is checked, using a mobile device
(smartphone, tablet or notebook) and connecting to the wireless router
from a position which is close to the installation site of the inverter.
Some installation examples are provided below in different conditions
and with the maximum recommended distances between the Inverter
and the wireless router.
