Generac PWRcell › Problems
Generac PWRcell shows offline or no data in the PWRview app
The PWRview app shows the PWRcell system offline or stops getting live and historical data. This page covers what the inverter's Internet light and the app's messages mean, what to check first, and the causes behind it.
What the lights mean
| What you see | What it means |
|---|---|
| Internet light on the inverter solid blue | The system is connected to the internet. |
| Internet light on the inverter strobing blue | Connected to the internet, and a REbus Beacon firmware update is running. Don't power off the inverter or unplug the Beacon while it runs. |
| Internet light on the inverter off | The system is not connected to the internet. |
| Ethernet link lights at the Beacon's RJ45 port flashing | The cable has a link, but flashing link lights alone don't prove an internet connection. |
Error codes that go with this problem
| Code | What it means |
|---|---|
| Error! Connection to Neurio servers failed, Error code = 4 | A Client Connection Error in the PWRview app: the app has lost its connection to the Neurio servers and gets no live or historical data. |
| REbus Beacon shows disabled on the device page | No time-of-use schedule is set. It does not mean the Beacon is disconnected. |
What to check first
- Look at the Internet light on the front of the inverter and note whether it is solid blue, strobing blue or off.
- If the Internet light is strobing blue, leave the inverter on and the Beacon plugged in. A firmware update is running.
- Write down any error message the PWRview app shows, including the error code number.
- Check that the Ethernet cable from your home network is plugged in at the inverter.
- Check where that Ethernet cable connects in your home. Generac wants it on a router, not the modem, and does not support or recommend Wi-Fi extenders.
- If the app shows Connection to Neurio servers failed, contact Generac support. If the Internet light stays off, call your installer; the next checks are inside the inverter.
