Inverter failure is the #1 cause of solar system outages. Here's how to diagnose it, reset it, and file a warranty claim directly — even if your installer is gone.
Inverter warranties by brand
What to do when your inverter fails
Read the inverter status lights
Walk to your inverter and check the LED status lights or display screen. This tells you what's wrong before you call anyone.
Solid green: Inverter is communicating normally — issue may be with panels or monitoring, not the inverter itself.
Flashing green: Normal operation at partial capacity — common in morning and evening.
Red or orange: Fault detected — this is a warranty situation. Note the error code.
No lights: Check your solar breaker and AC disconnect switch first.
Try a manual reset
A reset resolves about 20% of inverter faults. Try this before filing a warranty claim.
All inverters: Turn off the AC disconnect switch → wait 60 seconds → turn back on. Wait 15 minutes before checking.
Enphase IQ Gateway: Hold the reset button for 5 seconds until the LED flashes, or reset via the Enlighten app.
SolarEdge: Use the on/off switch on the inverter. Wait 2 full minutes before turning back on.
Tesla Gateway: Use the Tesla app → Energy → your system → Support to initiate a remote reset.
SMA / Fronius / Growatt: Power off via the DC disconnect, wait 5 minutes, power back on.
Confirm your installer status
If your installer is still in business, call them — they are obligated to diagnose inverter failures under the workmanship warranty.
If your installer went bankrupt or closed: your inverter manufacturer warranty is completely unaffected. Skip to Step 4 and file directly with the manufacturer.
File your inverter warranty claim
Every major inverter manufacturer accepts direct homeowner warranty claims — you do not need your installer. You'll need your inverter serial number, install date, error codes, and a description of the issue.
Solar Warranty Navigator generates a complete, inverter-specific warranty claim letter and action plan in under 5 minutes — with the right manufacturer contacts, required documentation, and escalation templates if your first claim is denied.
