SolarEdge Inverter No Communication: Safe Steps to Try
A "No communication" alert from SolarEdge means your inverter's data is not reaching SolarEdge, so the app shows no new numbers. A short gap is normal: SolarEdge raises this alert after the inverter has been offline for 3 hours or more.
What it means
The alert can read "No communication with the site," "No communication with the inverter," or the app may simply show no data. The steps are the same for each.
Data normally refreshes about every 15 minutes, and a short gap is normal.
What you can safely try
These steps may get the data flowing again:
- Check that your internet works through your router.
- Make sure the router and modem are powered on and connected.
- If you recently changed your router or Wi-Fi password, recheck the connection.
- Restart your router.
- Look at the light on the inverter without opening anything. A blue light (or "S_OK" on older models with a screen) means it is talking to SolarEdge.
When to stop and call
Stop and call us if:
- Data still does not show after the steps above.
- The inverter shows a red light, or the app shows Production issue detected on a sunny day.
- The inverter shows OFF mode. We ask for a quick call first; see our OFF mode guide.
- A burning smell, smoke, sparks, heat, buzzing, melting, water on or in equipment, or visible damage: stay away from the equipment, keep children and pets away, call 911 if there is smoke or fire, and book an urgent technician visit.

Frequently Asked Questions
What does No communication mean on a SolarEdge inverter?
SolarEdge is not getting data from your inverter, so the app shows nothing new. Checking your internet and restarting your router may fix it.
How often does the SolarEdge app update?
Data normally refreshes about every 15 minutes. SolarEdge raises a no-communication alert after the inverter has been offline for 3 hours or more, so a short gap is normal.
What does the blue light on a SolarEdge inverter mean?
A blue light, or S_OK on older models with a screen, means the inverter is talking to SolarEdge.
I changed my router. Is that why SolarEdge lost connection?
SolarEdge's steps include rechecking the connection after any router or password change. Restart the router as well, and if data still does not show, book a technician.
What if my SolarEdge data still does not show?
If data still does not show after the router checks, book a technician.
Send Sunny a photo
Not sure which alert you are looking at? Sunny, the chat assistant on this site, can read a photo of the screen. Open the chat on this page, tap the paperclip, and send a photo of your app or the equipment screen. Sunny answers day or night, tells you what the alert generally means and whether there is a safe step to try, and can take your address and a good time for a technician if one is needed.
Book a diagnostic
If the alert keeps coming back, or the steps above do not clear it, book a $395 on-site diagnostic visit. A licensed technician looks at the system and you get a written report with photos. Call or text (813) 285-4505, or request a visit on our solar repair page or our contact page. To keep a working system in good shape, see our solar maintenance plans.
