SolarEdge inverter troubleshooting
Solar energy is a smart move for your home, especially when paired with a trusted brand like SolarEdge. Their inverters are built for performance, but like any device, they can run into problems. If your system isn’t working right or your energy output drops, it’s time to look into SolarEdge inverter troubleshooting.
This guide walks you through simple steps to understand what might be wrong, what you can do on your own, and when to call a solar expert.
Why Your SolarEdge Inverter Might Have Issues
SolarEdge inverters work hard every day, converting sunlight into power for your home. But since they’re electronic devices exposed to heat, moisture, and daily use, problems can still happen. The good news is, many issues are easy to spot and even easier to fix.
Most problems are linked to communication errors, power flow, weather conditions, or simple software glitches. If you live in a hot, humid area like Miami, salt in the air and high temps can also impact your solar system over time.
Step 1: Check the Inverter’s Screen or Monitoring App
Start with the basics. Your SolarEdge inverter has a screen (or lights) that show system status. If you’re using the SolarEdge monitoring app or web portal, check if the system is updating properly. If it’s not, your inverter may not be communicating with the server.
Look for error messages or warning signs like:
- “No communication with server”
- “AC voltage too high”
- “Inverter not producing”
- “Arc fault detected”
- “DC voltage too low”
These messages can help you or a solar company figure out what’s going on.
Step 2: Restart Your Inverter Safely
Sometimes, your SolarEdge inverter just needs a simple reboot. This helps clear out temporary bugs or minor errors.
To restart safely:
- Turn off the inverter using the DC switch.
- Turn off the AC disconnect (breaker).
- Wait 5 minutes.
- Turn the AC breaker back on.
- Then turn on the DC switch.
After restarting, give it a few minutes. You may see the inverter lights flash as it reconnects to the grid and the monitoring system.
If the system goes back to normal, great! If not, keep reading.
Step 3: Check Your Internet or Network Connection
If the inverter seems fine but you’re not seeing updates in your SolarEdge app, your Wi-Fi might be the problem. A lot of solar service issues are actually caused by a lost internet signal.
Here’s what to do:
- Make sure your home Wi-Fi is working.
- Restart your router or modem.
- Reconnect the inverter to the network using the SolarEdge SetApp.
If your inverter uses cellular or Ethernet instead of Wi-Fi, check those connections too. Once the inverter reconnects to the network, your data should begin showing again.
Step 4: Look for Physical Damage or Warning Signs
Walk outside and look at the inverter. You don’t need to open anything, just take a look:
- Do you see cracks, burn marks, or loose wires?
- Is there water around the inverter?
- Does it smell burnt or make strange noises?
- Is the inverter screen blank or flashing nonstop?
If you notice anything unusual, it’s best to stop and call a professional. Safety comes first, especially with electrical equipment.
Step 5: Understand Common Error Codes
SolarEdge inverters use specific error codes to explain issues. You can find full code lists on their website, but here are a few common ones:
- Error 18x – A ground fault. This means there’s a possible wiring issue or moisture in the system.
- Error 25x – A communication error between the inverter and monitoring server.
- Error 33x – A problem with the grid connection, like voltage being too high or low.
If you see an error code, note it down. This info helps your solar installer or solar expert fix the problem faster.
When to Call a Solar Professional
If you’ve tried restarting the inverter and checked your Wi-Fi, but the system still isn’t working—or if you see an error that sounds serious—it’s time to contact a technician.
SolarEdge inverters are complex and use advanced electronics. Some repairs require software updates, special tools, or licensed knowledge.
Also, if your inverter is still under warranty, you may be able to get the repair or replacement at no extra cost. Many warranties last 12 to 25 years, depending on your installer and manufacturer.
How to Avoid Inverter Problems in the Future
Most inverter issues can be prevented with regular care and check-ups. Here’s how to keep your system healthy:
- Schedule an annual inspection with a certified solar service company.
- Keep the area around your inverter dry and clean.
- Check your monitoring app weekly to catch drops in performance early.
- After major storms, have your system inspected—especially in areas like Miami where strong winds and rain are common.
Choosing a local solar company with SolarEdge experience can make all the difference. They’ll know the local weather patterns and how to protect your equipment in coastal areas.
FAQ: SolarEdge Inverter Troubleshooting
Why is my SolarEdge inverter not producing power?
This could be due to a grid issue, faulty wiring, a failed inverter, or dirty solar panels. Start by checking error messages or restarting the system.
Can I fix my SolarEdge inverter myself?
You can reboot the system or reconnect the Wi-Fi, but most repairs should be done by a qualified solar installer for safety and warranty protection.
What does “no communication with server” mean?
It means the inverter can’t send data to the monitoring platform. Check your internet connection, or reconnect it using SetApp.
How long does it take for the inverter to restart?
After a reboot, it usually takes 5–10 minutes for the system to come back online and start producing power again.
Is inverter failure common in hot climates like Miami?
It can happen more often due to heat and humidity. That’s why choosing the right installer, keeping your inverter cool and clean, and getting regular check-ups is important.
Need Professional Help?
Don’t wait too long if your system isn’t working. Fast action can protect your warranty and get your energy flowing again. Whether you need a repair, software update, or just a second opinion, a licensed solar expert in Miami can help.
