Do you have a Growatt MTL Solar Inverter No AC Connection Issue?
Growatt MTL Solar Inverter No AC Connection message on your inverter screen? If so you’ve come to the right place for help!
With the No AC Connection issue the red Fault light is on and the screen displays the “No AC Connection” message. This means that the inverter is not detecting any electricity from the power grid or from the switchboard and needs to be checked right away.
What can you do about a Growatt MTL Solar Inverter No AC Connection issue?
The first thing you should do is check if the Inverter AC Isolator (if applicable this would be beside your inverter) and the Solar Supply Main Switch in your switchboard are on. Check also that there has not been a power failure as a power failure would give the same message.
If after checking the above the inverter still says “No AC Connection”, what you’ll need to do is contact a solar accredited electrician to come and have a look at your system and work out what’s causing the problem. They will check if you’re getting the right voltage from the electricity grid to the inverter.
Still no AC Connection on your Growatt MRL solar inverter? One more thing…
Ok so your electrician has checked the AC voltage at the inverter and it’s all good? There is one more thing that your electrician can try and that’s a small fuse inside the Growatt MTL inverter.
In our experience we’ve found that this fuse can blow and all that’s required is a replacement fuse be installed and away the Growatt MTL goes! The following image shows the location of the fuse – HAZARDOUS VOLTAGES MAY BE PRESENT INSIDE THE INVERTER EVEN WHEN TURNED OFF – ALL ELECTRICAL WORK MUST BE PERFORMED BY A LICENSED ELECTRICIAN!!

Hi Jason, the fuse in your Growatt 5000MTL inverter should be a 30A unit rather than a 25A. This should rectify your Growatt issue. Thanks and all the best with it!
I have a Growatt 5000MTL inverter. The fuse (F25AL/240v) was blowed and replaced. It works about 3~4 weeks, it blowed again. What type of the fuse should be on this model, slow blow fuse 25A? In the manual, it says the Max current output is 25A, is the 25A fuse (normal type) too marginal?
Thanks.
Great to hear you got it all sorted out Brett! Happy Days!
The fuse was the problem. Got it replaced and away it goes again- so simple AND cheap to repair. Thanks guys
