Recommendations for the wireless signal power
The radio signal level between the inverter and the wireless router can be
improved in a number of ways:
1. Change the direction of the antenna.
The antenna has a dead zone at its tip, which should not be positioned
facing the wireless router, as shown in the gure.
2. Find a new position for the router considering the different types of
materials which the radio signal will have to pass through:
Material Relative signal reduction
Open eld 0% (strength of approximately 50 metres)
Wood / Glass From 0 to 10%
Stone / Plywood From 10 to 40%
Reinforced concrete From 60 to 90%
Metal Up to 100 %
The quality of the RF signal can be assessed during the installation stage
where the signal is displayed in dBm.
3. Install a wireless signal repeater and place it in an area between the
inverter and the router, trying to make sure that the most critical obstacles
are avoided.
