How do I configure WIFI?

<p>The inverter is not connected to the server.&nbsp;</p><figure class="image"><img alt="无法上网.png" src="/uploads/_b7004d5eb2.png" srcset="/uploads/thumbnail__b7004d5eb2.png 245w, /uploads/small__b7004d5eb2.png 500w, /uploads/medium__b7004d5eb2.png 750w, /uploads/large__b7004d5eb2.png 1000w" sizes="100vw" width="1000"></figure><p>Firstly, please make sure that WIFI module is not defective by connecting to other networks regardless of mobile hotspots or another WIFI, and then check whether the network you want to connect to is working normally, meanwhile make sure that MAC address of WIFI module is in the white list of the network.&nbsp;</p>

Why does the indicator of WIFI module keep flashing?

<p>It means communication between battery and inverter is faulty.</p><figure class="image image_resized" style="width:76.73%;"><img alt="com灯红色.png" src="/uploads/com_dda629cf4c.png" srcset="/uploads/thumbnail_com_dda629cf4c.png 208w, /uploads/small_com_dda629cf4c.png 500w, /uploads/medium_com_dda629cf4c.png 750w, /uploads/large_com_dda629cf4c.png 1000w" sizes="100vw" width="1000"></figure><p>&nbsp;Following actions can be taken to fix this issue.<br>①Check whether the proper battery model is chosen.<br>②Check whether the communication wire is broken, and if so, please replace it.<br>③Check if the connection between the battery and the inverter is correct and well.<br>④Check if the CAN wire is connected to the proper RJ45 terminal.</p>

What does it mean if the communication (COM) indicator is red and how to handle it?

<p>It means communication between meter and inverter is faulty.</p><figure class="image image_resized" style="width:71.06%;"><img src="/uploads/com_46db869e9c.png" alt="com灯黄色.png" srcset="/uploads/thumbnail_com_46db869e9c.png 208w, /uploads/small_com_46db869e9c.png 500w, /uploads/medium_com_46db869e9c.png 750w, /uploads/large_com_46db869e9c.png 1000w" sizes="100vw" width="1000"></figure><p>Following actions can be taken to fix this issue.<br>①Check if the connection between the meter and the inverter is correct and well.<br>②Ensure that used meter is compatible with Solinteg inverter.<br>③The communication wire between meter and CT or the grid side should be shorter than 3 meters.</p><p>If your solar system adopts master-slave parallel strategy, since the slave inverters are not necessary to be connected with the meters, it is normal that all COM indicators of slave ones will be orange.</p>

<p>If SOC drops to 0 in a flash and then rise immediately, SOC calibration function is activated, which is normal. However, if SOC remains 0 for quite a long time, please contact battery supplier or email <span style="color:#1565c0;">service@solinteg.com</span></p>
