How to Restart a SolarEdge Inverter Safely: Step-by-Step Guide for Homeowners
Key takeaways
A SolarEdge inverter can sometimes be restarted safely by turning the AC supply off first, isolating the DC side second, waiting for full shutdown, and restoring power in the reverse order.
A restart is useful for some temporary interruptions, but it is not the right answer for repeated trips, visible damage, burning smells, water ingress, or persistent error codes.
Only use clearly labelled system switches. Do not remove covers, open the inverter, or touch internal wiring.
If the inverter does not recover cleanly after restart, the next step is proper solar fault finding rather than repeated resets.
If your SolarEdge inverter has stopped producing, dropped offline, or is showing a temporary fault, a careful restart can sometimes bring the system back online. The important word is careful. A solar inverter is not just another household appliance, and the shutdown and startup order matters.
This guide gives homeowners a practical restart process without pretending every inverter problem can be solved by cycling the power. Sometimes a restart helps. Sometimes it only confirms that the system needs proper diagnosis by a licensed solar electrician.
When a restart is worth trying
A restart is usually worth trying when the inverter or monitoring app has frozen, communication has dropped out, or the inverter has stopped producing without obvious physical damage. It can also help after some grid disturbances if the system does not recover on its own.
A restart is not the right move if you can see damaged components, smell overheating, notice water ingress, or the system keeps tripping protection devices. Those cases need fault finding, not repeated resets.
Before you start
Read the switch labels on the installed system before touching anything.
If possible, note the error code or take a screenshot from the display or monitoring app first.
Make sure the area is dry and safe to access.
Stop immediately if any switch, enclosure, or isolator looks heat-damaged or physically compromised.
Safety first before touching any switches
Only use the switches that are clearly labelled as part of the installed inverter system. Do not remove covers, open the inverter, or touch internal wiring. If the switch layout is unclear, stop there and get help.
SolarEdge systems can vary by model and installation layout, so the exact switch positions can differ from one property to the next. The labels on the installed system always matter more than a generic internet diagram.
How to restart a SolarEdge inverter step by step
1. Turn the AC supply off
Start by turning off the AC isolator or AC supply feeding the inverter. This is usually the first step because it disconnects the inverter from the house and grid side.
2. Isolate the DC side
Next, turn off the DC isolator or the clearly labelled DC isolation control for the solar input. The exact arrangement depends on the model and installation, so use the installed labels rather than guessing.
3. Wait for the inverter to shut down fully
Give the inverter enough time to fully de-energise. In practice, that means waiting until the display or indicators have cleared and allowing a few minutes before startup. Rushing the restart defeats the purpose of the process.
4. Turn the DC side back on first
Restore the DC side first so the inverter can receive input from the solar array again.
5. Turn the AC supply back on
After the DC side is restored, turn the AC supply back on. The inverter may take a short period to boot, check conditions, and return to normal operation.
What to check after restart
Has the display or monitoring app returned to normal?
Has generation resumed once the inverter completes startup?
Does the same warning, trip, or error return immediately?
Is there any sign the fault is weather-related, heat-related, or linked to a recent outage?
If the inverter restarts cleanly and generation resumes, the issue may have been temporary.
If the same fault returns, the restart has still been useful because it narrows the problem: the issue is probably not just a simple lock-up.
When not to keep resetting it
Repeated resets are not a troubleshooting strategy. If the inverter repeatedly shuts down, throws the same alarm, or trips again after restart, continuing to cycle it can waste time and hide the real issue.
This is especially true if the problem is linked to isolator damage, inverter overheating, grid-side issues, internal hardware faults, or degraded system components.
Those problems need testing and diagnosis, not more restarting.
Common problems a restart will not solve
Persistent error codes that reappear after startup
Failed or heat-damaged AC or DC isolators
Water ingress or storm-related damage
Low generation caused by component faults rather than software or communication issues
Repeated safety shutdowns tied to installation, wiring, or grid faults
If any of those are in play, the better next step is to book a solar fault inspection and identify the cause properly.
Common questions about restarting a SolarEdge inverter
What is the correct order to restart a SolarEdge inverter?
In most home systems, the usual restart order is to turn the AC supply off first, then isolate the DC side, wait for the inverter to fully shut down, then turn the DC side back on before restoring the AC supply. If the labels on your system differ, follow the SolarEdge manual and the installed switch labels.
How long should I wait before turning a SolarEdge inverter back on?
Wait until the inverter has fully powered down and the display or indicators have cleared. In practice, that usually means giving it a few minutes rather than immediately switching it back on.
Can restarting a SolarEdge inverter fix every fault?
No. A restart can help with some temporary faults or communication glitches, but repeated trips, persistent error codes, burning smells, water ingress, or visible damage need professional diagnosis instead of repeated resets.
What should I check after restarting the inverter?
Check whether the inverter display or app has returned to normal, whether generation resumes after startup, and whether the same fault or warning returns. If the inverter immediately drops back into alarm or standby, the issue usually needs proper fault finding.
When should I stop and call a solar electrician?
Stop and book a qualified solar electrician if the inverter shows the same error again, the isolators feel damaged, the unit smells burnt, there has been storm or water damage, or you are not completely sure which switches are safe to operate.
