Every now and then, a customer of ours will call up to report communication issues with the Enphase Microinverters installed with their solar panels.

If you have solar panels with Enphase Microinverters, chances are you will be a user of their fantastic free online monitoring software MyEnlighten. However, if your MyEnlighten account has stopped updating with current production data, it may be that your system is no longer connected to the Internet.

This can be checked by looking at the status indicator at the top of your MyEnlighten overview screen:

If you see the message ‘This system isn’t reporting to Enlighten. Is your internet connection down?’ it means that your Envoy is offline and unable to upload data. You may also notice that the display on your Envoy looks like this, with -Web showing in the top right:

This also means that the Envoy is not connected to the internet. Only when you see + Web is the Envoy online.

The first thing to do is make sure your internet is working. Check to see that other devices in your home are successfully online and if not, you may need to contact your service provider to assist in getting you reconnected. If the Internet is working in your home, it has probably lost connection to the Envoy.

Because the Envoys in most of our customers’ properties are located in a separate room to their Internet router, they are too far apart to connect directly. Therefore we have to use TP Links, or Ethernet bridges (or Power Line Communicators), to connect the two together. These TP links come as a pair and you will have one attached to the Envoy via an Ethernet cable and another connected to your router via an Ethernet cable. The two TP links need to be synced up with each other but can lose communication from time to time. All you need to do is re-pair the two TP Links, instructions on which can be seen in the video below. Please note - it is advised that TP links are plugged directly into the wall socket and not into multi-adapters. We have used a four-way socket in the video but this is for illustration purposes only.
