Is your Growatt less than 5 years old?
If your Growatt is less than 5 years old, you will be covered by warranty. You will need proof of purchase, ie the invoice or proof of installation by way of the Certificate of Compliance. You will also need the details of the inverter model and fault. Growatt have an office in Australia and are generally pretty responsive when it comes to claiming under warranty.
What if the Growatt is over 5 years old?
If the Growatt is more than 5 years old unfortunately you have no warranty, so will need to replace the inverter at your own cost.
There is no-one is South Australia who repairs inverters, so it is not feasible to get them repaired.
We recommend you replace your Growatt with a quality new inverter with a brand new warranty, so you have peace of mind for years to come.
