“Do your homework, look around. I'd recommend VoltX Energy. I think it was value for money.”
The change since installation has been significant. On a good month, the only charges left on Mick's electricity bill are the off-peak water heating and the daily supply charge. Electricity prices, which had been a constant source of frustration, are no longer something he thinks about.
Great experience from start to finish
Once the deposit was made, our battery system was installed within two weeks. It was up and running in four hours, with only a 20 minute interruption to the power. The team, from sales to installers, made the whole process seamless.

Frequently Asked Questions
What is the VoltX Energy Solar Battery Offer?
The VoltX Energy Solar Battery Offer is a limited-time opportunity to purchase a qualifying VoltX Energy Solar Battery System at promotional pricing. The VoltX™ AlphaESS Solar Battery is available from $3,999 under this offer.
Who is eligible for the offer?
The offer is available to Australian residents aged 18 years or over who purchase a qualifying VoltX Energy Solar Battery System for a residential property in NSW, ACT, QLD, SA or VIC during the promotional period. Eligibility is also subject to installation and technical requirements.
Why is the VoltX AlphaESS Solar Battery from $3,999?
The advertised from $3,999 price reflects applicable promotional pricing and eligible government incentives. Final pricing may vary depending on your eligibility for available rebates and incentives, as well as your installation requirements.
Do I need to have solar panels already?
Your property must have an existing solar PV system or have a new solar system installed alongside your battery. This allows your battery to store excess solar energy for use when your home needs it.
Are there any additional installation costs?
The advertised price is subject to a technical assessment and the requirements of your property. Additional costs may apply for site-specific work such as switchboard upgrades, longer cable runs, or other electrical work. Any applicable additional costs will be discussed with you before installation.
Why install a solar battery now?
Battery rebates are changing over time, while new energy initiatives are creating more opportunities to get value from battery storage. Virtual Power Plants (VPPs), the Solar Sharer Offer, and other energy programs can help eligible households make better use of their stored energy.
When does the offer end?
The offer is available for a limited time only. Promotional pricing may end without further notice, subject to product availability and the applicable terms and conditions.
Can I combine this offer with other promotions or discounts?
The promotional pricing cannot be combined with other VoltX Energy offers, discounts or promotions unless expressly stated otherwise. Eligibility for government rebates and other third-party incentives is subject to their individual terms and requirements.
