Check that the configuration procedure has been carried out correctly and that the
correct network password has been entered.
-
When searching for the Wi-Fi network using a smartphone or PC, make sure that the
Wi-Fi signal is strong enough (a minimum RSSI signal strength of 30% is required
during configuration). If necessary, increase it by using a network extender or a
router dedicated to inverter monitoring.
-
Check that the router has access to the network and that the connection is stable;
check that a PC or smartphone can access the Internet
-
Check that port 80 of the router is open and enabled to send data
-
Reset the adapter as described in the previous section
If, at the end of the previous checks and subsequent configuration, Remote server A is still
“Not Connected” or the NET LED is off, there may be a transmission problem at the home
network level and, more specifically, that data between the router and server is not being
transmitted correctly. In this case, it is advisable to carry out checks at the router level in
order to ensure that there are no obstructions on the output of data packets to our server.
To make sure that the problem lies in the home router and to exclude problems with the Wi-
Fi adapter, configure the adapter using the Wi-Fi hotspot function on your smartphone as a
reference wireless network.
