Solar How do I restart my solar system after a shutdown?
Restart your solar system only to your installer's or manufacturer's instructions, and expect a waiting period before it exports power again.
Restart a solar system only as your installer or the manufacturer instructs for your specific equipment. Order and method vary by brand, and a system shut down after a fault or storm damage should be inspected first. After starting, inverters commonly wait before exporting power again. Contact your installer for the right procedure.
Why isn't restarting just the shutdown in reverse?
It can look that simple, but the right sequence depends on your inverter, whether you have a battery and how your system was installed. Panels also keep producing power whenever there is light, so parts of the system can be live while other parts appear off. Guessing the order risks damaging the equipment or leaving it in an unsafe state.
That is why we don't list steps here. Your installer's instructions and the maker's manual are the ones that apply to your system.
Why does it take time to start exporting?
Grid-connected inverters are built to check the grid before they feed power into it. Sources describing restarts mention a waiting period before the system begins exporting, so a display that shows a message or no output straight away is not necessarily a fault. The waiting period varies by inverter, so your manual or installer will tell you what is normal for yours.
What if it was shut down because of a fault?
A fault shutdown means something detected a problem. Starting it again does not fix the cause, and a fault that keeps returning can be a safety issue. Note the code and call your installer or a licensed electrician rather than repeating attempts.
What about battery systems?
A battery has its own start-up procedure set by the manufacturer. It can also hold stored energy, so it needs particular care. Ask your installer or the battery maker for the correct procedure for your model.
Who should I contact?
Start with your installer, because they know your system and warranty position. If that is not possible, a licensed electrician with solar experience can help. Rental tenants should contact their landlord or property manager.
What to note and tell them
What was done and when
Write down why the system was shut down, who did it and the time.
What the display or app shows now
Photograph the inverter display or monitoring app without touching anything. Note any error code or coloured light.
Any visible damage
From a safe distance, note anything wet, scorched or broken. Do not go on the roof or open any covers.
Make and model
Photograph the labels on the inverter and battery so the installer can find the right manual.
What should I ask for before the next time?
Written instructions
The easiest time to get the right procedure is before you need it. Ask your installer to give you written instructions for your own system, including what is safe for a homeowner to do and what is not. Keep them with your manuals and installation paperwork.
What the installer will check
Before bringing a system back into service after a fault or storm, a licensed installer will look over the panels, cabling, isolators and inverter for damage, check that the connections are sound and confirm the system is operating as expected. That is the kind of check a homeowner cannot do by looking at a display.
Frequently asked questions
It varies by inverter, but most wait for a short period while they check the grid. Your manual or installer can tell you what is normal for your model.
It can be. The unit may be going through its start-up checks. If it stays blank or shows an error, note the code and call your installer.
Not until a licensed installer has inspected it if there is any chance of damage. Water or storm damage can leave equipment unsafe.
Yes, batteries have their own procedure from the manufacturer. Ask your installer or the battery maker.
Repeated faults need a licensed installer. Write down the code and the times it appears and keep clear of the equipment.
