Solar Monitoring Offline: What "No Communication" Really Means

If your solar app says "No communication," "Gateway offline," or stops updating, it does not always mean your solar is not producing. This guide helps you figure out whether your system is truly down or whether it is only a monitoring issue, without tools and without opening any equipment.

First: Is This Only a Reporting Problem?

Many systems keep producing even when the monitoring gateway loses internet. Start here so you don't assume the worst:

• Check whether the app shows a specific "last updated" date and time
• Look at your monitoring "Week" or "Month" view for a sudden drop to zero after a specific day
• Check your utility bill for export / "delivered to grid" activity during the same period
• If you have batteries, check whether they are cycling (charging/discharging) as usual

Common Reasons Monitoring Goes Offline

• Home internet outage or router restart
• Wi-Fi password changed and the gateway never reconnected
• Gateway lost signal (weak Wi-Fi, moved router, new walls/metal cabinet)
• Cellular gateway subscription expired (on some systems)
• Utility meter swap or service work that triggered a temporary shutdown event
• Inverter fault or shutdown (less common than internet issues, but possible)

Quick Checks You Can Do Safely

These checks do not require opening electrical equipment:

• Confirm your home internet is working (try loading a website on Wi-Fi)
• Restart your router (many monitoring issues resolve after a router reboot)
• If your app has a "device status" section, note any listed gateway/inverter status
• If you can see the inverter display (without opening anything), take a photo of what it shows

How to Tell If Production Might Actually Be Down

Monitoring being offline is common. These are the signs that may point to a real production issue:

• Your app shows zero production and your utility bill shows no export for the same period
• The "last updated" timestamp aligns with a spike in your electric bill
• The inverter display shows an error or shutdown message (photo helps)
• You see repeated "fault" alerts (not just "offline") in the app notifications

What to Send Us for a Fast Answer

If you want us to quickly tell you whether this is just monitoring or likely a real production issue, send:

• A screenshot of your monitoring "Month" view
• A screenshot showing the "last updated" date/time (or "No communication" message)
• Any error message screens
• A photo of the inverter screen (if it has one and is visible without opening anything)
• A screenshot of the utility bill page that shows usage and export (if available)
