SolarEdge Error 11 — Hardware Error Fix Guide

What Does This Error Mean?

SolarEdge Error 11 is a hardware error indicating the inverter's internal self-test detected a fault in the power electronics. Try power-cycling the inverter first. If Error 11 returns, the inverter will likely need replacement or repair under warranty.

Affected Models

SolarEdge SE2200H
SolarEdge SE3000H
SolarEdge SE5000H
SolarEdge SE7000H
SolarEdge SE10000H
SolarEdge StorEdge
SolarEdge Three-Phase Inverters

Common Causes

Internal component failure — IGBT, capacitor, or gate driver fault
Inverter overheated over an extended period and damaged internal components
Power surge from the grid damaging the AC-side electronics
Moisture ingress into the inverter casing
End-of-life failure in an older unit

How to Fix It

Power-cycle the inverter.

Turn off the AC isolator switch and the DC switch on the inverter. Wait 5 minutes for capacitors to discharge. Turn the DC switch back on, then the AC isolator. Wait for the inverter to complete its startup sequence.
Check whether Error 11 clears after restart.

If the inverter restarts successfully and produces power for a day without returning Error 11, monitor it closely for recurrence. A single occurrence can be caused by a transient power event.
Check the inverter display for secondary codes.

After Error 11, some SolarEdge units display a secondary code or a timestamp. Take a photo of the display and note the exact error text — this information is valuable for the service technician.
Contact your solar installer.

Error 11 typically requires a warranty assessment. Your installer will retrieve the fault log from the inverter and liaise with SolarEdge support. Do not attempt to open the inverter casing — it contains live DC voltage even when switched off.
Check the warranty status.

SolarEdge inverters come with a 12-year standard warranty, extendable to 20 or 25 years if registered on the monitoring portal within 30 days of installation. Warranty replacements are usually processed within 5–10 business days.

When to Call a Professional

Yes — Error 11 is an internal hardware fault. Contact your solar installer or SolarEdge support. Do not continue operating the inverter without diagnosis. SolarEdge inverters carry a 12-year standard warranty.

Frequently Asked Questions

SolarEdge Error 11 appeared after a storm — is the inverter damaged?

Possibly — lightning-induced surges are a common cause of Error 11. Check whether surge protection devices on the AC or DC side have tripped or blown. Contact your installer to inspect the inverter — storm damage may be covered by home insurance rather than the product warranty.

My SolarEdge inverter is 3 years old and shows Error 11 — will it be replaced for free?

If the inverter is within its 12-year standard warranty period and the fault is not caused by external damage (lightning, flooding), SolarEdge should replace it at no cost. Contact your installer to initiate a warranty claim.
