Absolutely Amazing VoltX Energy Thank You!
I cannot recommend VoltX Energy highly enough!From registering with VoltX to having my 28kW Alpha ESS battery installed was exactly 8 days – an outstanding turnaround!
The installation team arrived 30 minutes ahead of schedule. They were professional, friendly and knowledgeable, conducted an initial site assessment and immediately got started.
The installation was exceptionally clean and efficient, with absolutely no mess left behind.
On completion, the team provided a comprehensive orientation of the system, including downloading and setting up the Alpha ESS App on my phone. The system also connects with my energy provider through a Virtual Power Plant (VPP), helping manage solar curtailment and maximise feed-in tariff opportunities.
And the price? Just $3,700 fully installed!
Even more incredible, within just 3 days, my electricity bill was reduced to ZERO!
The quality of the product, professional installation, comprehensive warranty and overall customer experience have exceeded my expectations.
Thank you, VoltX Energy, for delivering on your advertised promises and making something I honestly thought would never become a reality.
I now feel like I've taken back control of my energy costs and dramatically reduced my dependence on the electricity market and those dreaded monthly power bills!
Absolutely Amazing! Outstanding Value! Exceptional Service!
If you're considering a home battery, do yourself a favour and speak with VoltX Energy.

Value for money system
My Son ( Mech. Eng.) arranged for the purchase and installation of the system as I was away for 3 months. The installation is neat and the system works really well 35 kwh battery and 3 phase inverter, already had solar on roof and haven't use a single kw of grid power in 2 months. For the price this unit is good and I recomended it.10 November 2026

Good installation
Workmanship is excellent, perhaps putting the batteries up off the paving would be a good idea, to prevent corrosion of the battery containers.Battery rating: 5/5

Fast and professional 27.9kWh AlphaESS battery installation in SA!
I recently had a 27.9kWh AlphaESS solar battery system installed at my property in South Australia through VoltX, and I couldn't be happier with the experience.After looking into battery options to maximise our solar setup, VoltX offered a highly competitive package that made perfect financial sense. The communication leading up to the day was excellent, but what blew me away was the efficiency of the installation team. They arrived fully prepared and had the entire massive 27.9kWh system completely installed, wired up, and commissioned in just a few hours.
The workmanship was top-tier—the wiring is incredibly neat, and they left the site perfectly clean. Before heading off, they made sure I was fully set up on the AlphaESS monitoring app so I could track our storage and consumption in real time.
Having this much storage capacity completely changes how we manage our power bills here in SA, especially during peak evening times. If you are looking for a professional, lightning-fast battery installation, I highly recommend VoltX.
Battery rating: 5/5

Great company to deal with
I found it a pleasure to deal with VoltX the quote for my solar batteries arrived fast and the process was very easy, the installation was carried out by two men in four hours and they did a great job and cleaned up the area when finished, I had a question after installation about upgrading to a larger inverter and Sam from customer service was quick to find the answer for me from their technical team and sent me the information needed, nothing was a problem for them, I found them helpful and courteous.Highly recommend

Sceptic to Fan
Frankly, I was sceptical because of review ratios, but also curious. So I enquired and asked questions, courteously yet direct, about my concerns on their ratings. The consultant didn’t try to make excuses, but addressed each concern to my satisfaction.From there, things just got better and better, general technical advice (I’d already had a smaller AlphaESS for 5 years), the clearly defined procedure from refundable $100 deposit, information I had to provide about my system site and confirmation of a quote, through to placing my order, installation and commissioning.
The system was installed in less than the projected time. The installation crew were great. They left our site neat and clean, and the system was inspected and passed well within the projected time.
From skeptic to fan! So much so that my neighbour is also having a battery system installed.

Top Class Experience
Couldn't fault the process from start to finish. The quote was clear and unhurried … no hard sell, and they actually explained how the battery would work with our existing solar rather than just quoting a box. The planning stage was thorough: switchboard checked properly, placement discussed, expectations set before anyone turned up.The install itself was tidy and professional. Everyone I dealt with … from the first call through to the installers on site … was pleasant, easy to deal with, and happy to answer questions without making me feel like I was holding them up.
The system has been running for a few days now and is doing exactly what it was meant to: covering the evening load and exporting the surplus during the day. It's too early to comment on long-term product quality, but on the strength of the process and the first few days of operation, I'd happily recommend them.

Sensational service from start to finish. The ordering process was easy and straight forward and the install was way beyond my expectations. The installers set up the app on my phone and when I had an issue with it, they cam back twice very quickly and sorted it out. Can recommend the company and its products.03 November 2026

Fantastic Solar battery Installer
Great price, I highly recommend Voltx Energy, I received great service from sales/quoting, customer service, the installation team, onboarding and everyone that I've dealt with in this company I cannot fault.All installation queries answered and explained really well as were the App and system by the installation team & onboarding team as well. Batteries installed after only 6 days from quote after initially estimated 4-6 weeks so was very happy it was installed sooner in SA.
I recommend this company to anyone looking to install Solar & battery systems and have found them to be the most efficient company I have dealt with.

Quality and Professional
Extremely happy with VoltX Energy. The installation process was professional by the qualified and experienced technicians, who were more than obliging in explaining to myself and my wife the whole process, including downloading and understanding the app so we can monitor the batteries usage. Most impressed and look forward to the savings this will bring to us.
