Solar Dynamics has closed: what owners can do now

Solar Dynamics, the family run solar installer at Mordialloc in Melbourne's south east, has stopped trading, and its company was deregistered in November 2025. If you own a Solar Dynamics system, it does not stop working because the business has gone, and the warranties from the makers of your panels, inverter and battery are separate from the installer. What has gone is the company you would have rung, so a few steps now will save you trouble later.

What happened to Solar Dynamics

This comes from public records, as they stood on 4 November 2026:

• SolarQuotes notes that Solar Dynamics has been reported as out of business, and said in May 2025 that its own investigation pointed the same way
• Solar Directory archived its listing in September 2025
• the ASIC company file shows Solar Dynamics Pty Ltd deregistered on 5 November 2025
• ABN Lookup shows its ABN cancelled on 11 November 2025

We found no notice of a liquidator or administrator on ASIC's published notices, so this reads as a business that stopped trading and closed its company. We have not seen anything on why.

Your Solar Dynamics system keeps running

A solar system does not need its installer to make power. If your inverter shows a fault, a breaker keeps tripping, or you notice scorching or a burning smell, ring a licensed electrician. Do not open the inverter or the isolators yourself.

Solar Dynamics warranties: what still stands

The makers' product warranties. Consumer Affairs Victoria says that if a product has a written warranty and is still inside the warranty period, you should contact the manufacturer directly when the business that sold it is insolvent. Solar Dynamics had a long list of brands, so find yours first. Ask who pays the labour to swap a faulty part, because that varies.

The installer's own warranty. Under Solar Victoria's rules, retailers in its program must give a minimum five year whole of system warranty that includes quality of work. That promise came from Solar Dynamics, so do not count on it now. Consumer Affairs Victoria on 1300 558 181 can tell you what options remain for a workmanship problem.

Find the brands on your Solar Dynamics system

SolarQuotes lists many brands against Solar Dynamics, among them Fronius, Sungrow, GoodWe, Enphase, SolarEdge and Redback inverters, and Tesla, BYD, Sonnen and Sungrow batteries. Check your own gear rather than relying on that list.

Photograph the label on your inverter and any battery, close enough to read the brand, the model and the serial number. Do not remove any covers. Your invoice or warranty papers should name the panel brand. Keep those with your Certificate of Electrical Safety, the install date and any monitoring login details.

Get your monitoring in your own name

Check you can still log in to your inverter or battery app. If the account was set up under a Solar Dynamics email address, contact the maker and ask how to move it to your own. Monitoring is how a fault gets spotted early.

Who can service a Solar Dynamics system

Any licensed electrician who works on solar can look at a Solar Dynamics system and tell you what it is doing. When you ring around, give them the brands and models, the age of the system and what you are seeing, and send your photos.

Trentham Energy is an electrical and solar business that works across Melbourne's south east and bayside as well as central Victoria. We cannot take over the old Solar Dynamics workmanship warranty, as that promise belonged to the business. What we can do is check the system, tell you what is wrong and help you take a product fault to the maker. Send us your photos and tell us what it is doing, and we will tell you plainly what we can do: get in touch.

Questions

Is Solar Dynamics still trading?

The public records say no. Its company was deregistered on 5 November 2025 and its ABN was cancelled six days later. If you know different, you can ask us to correct the record on our Solar Dynamics page.

Can I still claim a warranty on a Solar Dynamics system?

On the products, usually yes, by going to the manufacturer directly while the warranty runs. The installer's own workmanship warranty came from a business that has closed, so do not count on that part.

Who do I call about a fault on my Solar Dynamics system?

A licensed electrician who works on solar. Have your photos of the labels ready, along with your invoice and the install date.
