Inverter Wifi Connection help

If you change your Wi-Fi settings follow the relevant instructional video to get the monitoring back up and running .

Some people have found it helpful to watch the video on one device and perform the steps on a second device that way they can play and pause the video as they do each step on the other device.

We aim to empower our customers to look after their own systems and save on a service call where possible.

If you have not changed internet providers then most of the time turning the PV system and inverter off can reconnect the inverter to your WiFi.

Please turn the inverter and PV system off and then back on again in this exact order. Please note, turning the system back on is in the reverse order see below:
1. Turn the AC switch off
2. Turn the DC (labelled PV array) switches off
3. Wait 1 min
4. Turn DC (labelled PV array) switches back on
5. Turn AC switch back on


If you have changed WiFi credentials then you will need to update these in your system via the following options.

SMA Wi-Fi Connection Instructions

Option 1:Connect to your SMA inverters WLAN using WPS

Pls check if your modem has a wps button.
If so you can knock (sound activated) on the front of the inverter 3 or 4 times until the blue light flashes.
Then push the wps button on modem within 1 min and it should auto connect.

Option 2: How to connect your SMA Inverter to a Wi-Fi network

The first step which isn’t outlined in the video below is that you need to connect to the inverter wifi network before you can follow the video. To do this open up your wifi setting and you should see a network called SMAXXXXX where the X’s are the inverters serial number. The password for the network can be found on the sticker on the side of the inverter (WPA2-PSK).  Once connected to the network you can follow the steps in the video below. When you login it will require a password. We generally don’t setup the user password at the time of installation so you should just be able to select user and then be prompted to create a password.
