Energy prices are on the rise, and homeowners must be conscious of how much they are spending on energy consumption. Luckily, the VoltX™ Neovolt battery system is a cutting-edge solution designed to help homeowners save on energy costs while improving overall energy efficiency. "By storing energy when it's cheapest and using it when grid prices peak," it offers a strategic, long-term approach to reducing electricity bills.
Store Energy When It's Cheapest and Use It When It Counts
The single biggest lever the VoltX™ Neovolt pulls on your bill is time-shifting your energy. With 9.6 kWh of base storage capacity (expandable in stacked modules to 19, 28, 38 or 48 kWh) and up to 98.4% max efficiency, the system charges when electricity is cheap or free and discharges when it's expensive.
There are two ways it does this:
Solar Self-Consumption
If you already have panels, the VoltX™ Neovolt stores your excess daytime generation instead of exporting it to the grid for a small feed-in tariff. This is where the real money is. Most Australian retailers now pay only 3–5c/kWh for exported solar, while charging 30–45c/kWh to buy power back at night. Every kilowatt-hour you store and use yourself is worth far more than the same kilowatt-hour exported, often 8–10x more.
The VoltX™ Neovolt's app-managed optimisation captures surplus sun during the day and releases it after dark, turning your solar system into a genuine savings tool rather than a low-value export scheme.
Off-Peak Grid Charging
On days with little sun, or for homes without solar, the battery can charge from the grid during off-peak windows (when rates are lowest) and discharge during peak-rate evenings. Either way, you avoid buying power at the most expensive times of day.
A Worked Example: What the Savings Actually Look Like
Consider a typical Australian household using around 20 kWh per day with a rooftop solar system.
Before the battery, much of the home's solar is exported at roughly 4c/kWh, while evening consumption is bought back at around 38c/kWh. Say the home exports 10 kWh a day and re-imports 10 kWh at night. That's about 40c earned on export versus $3.80 spent on import, a daily swing of roughly $3.40 the household loses to the grid.
With a VoltX™ Neovolt storing that same 10 kWh for evening use, most of that re-import disappears. At a 34c/kWh spread between what power costs to buy and what solar earns on export, storing 10 kWh a day is worth about $3.40 per day, or roughly $1,200 a year. Households on higher tariffs, with larger systems, or shifting more load into stored energy can save considerably more.
Payback Period
Using a single-phase VoltX™ Neovolt system priced around $5,300–$5,800 installed (with the federal Cheaper Home Batteries rebate already applied), combined with annual savings of $1,000–$1,500, points to a payback period of roughly four to six years. That’s comfortably inside the system's 10-year warranty and its expected 20-year service life.
Actual figures depend on your tariff, usage pattern, solar size and local feed-in rates, so treat this as an illustration rather than a quote. A VoltX Energy expert can model your actual savings and current pricing from your latest bill.
Real Bill-Reduction Examples
VoltX Energy customers across Australia have installed VoltX™ Neovolt systems and reported the same core outcome: sharply lower evening grid reliance and smaller bills. Recent installations in Ridgehaven and Wynn Vale in SA, and Quakers Hill and Edensor Park in NSW, are part of a growing base of over 1,100 reviewed installations, with customers consistently highlighting straightforward installation and real bill savings.
You can read verified installs and outcomes on the VoltX™ Case Studies and Customer Stories pages, which detail system sizes and the savings households have seen in their own words.
Capacity, Usable Storage and Warranty at a Glance
Knowing the numbers helps you match a system to your home:
- Base capacity: 9.6 kWh, expandable via stacked modules to 19, 28, 38 or 48 kWh (single-phase).
- Usable storage: its lithium-iron-phosphate chemistry delivers a high usable depth of discharge, with up to 98.4% max round-trip efficiency, meaning very little of the energy you store is lost.
- Cycle life: rated for 10,000 life cycles, supporting an expected service life of around 20 years.
- Warranty: 10-year battery warranty and 10-year inverter warranty, supported directly by VoltX Energy rather than an overseas manufacturer.
- Compatibility: works with existing solar and is fully managed through the VoltX™ Neovolt app.
Protect Yourself From Price Increases and Grid Fluctuations
The VoltX™ Neovolt also shields you from where energy prices are heading. As grid rates climb, every unit of power you've stored yourself is a unit you don't have to buy at tomorrow's higher price. By reducing how much you draw from the grid at peak times, the system adds a layer of financial predictability that a grid-only home simply doesn't have.
It can also keep essential appliances running during a blackout, depending on your configuration. If you want to set up your VoltX™ Neovolt for outage protection, we’ve covered how it works in a separate guide.
Smart Power Consumption Management
The VoltX™ Neovolt comes with smart technology that makes it easier than ever to monitor and manage power use. Through the app you can track consumption in real time and see exactly when the system is charging, discharging or drawing from the grid. The system automates the cost-saving decisions for you, switching between stored and grid energy to keep your home on the cheapest available source at any given moment, which cuts both your bills and wasted energy.
A Smarter Path to Energy Efficiency
Whether you're maximising an existing solar investment or simply escaping expensive peak-rate power, the VoltX™ Neovolt offers a versatile and effective approach to home energy management. Its ability to store cheap energy, protect you from rising prices, and reduce grid reliance makes it a standout choice for anyone serious about cutting energy costs. With benefits that extend well beyond immediate savings, it's a smart investment for homeowners wanting more control over their energy future.
Step into the future of home energy with the VoltX™ Neovolt system and enjoy a solution designed to save you money while keeping your home powered efficiently.
Frequently Asked Questions
How much can the VoltX™ Neovolt actually save me each year?
Savings depend on your tariff, usage and solar size, but a typical solar household shifting around 10 kWh a day into stored energy can save roughly $1,000–$1,500 per year by avoiding peak grid rates and low feed-in tariffs. VoltX Energy advisors can model your specific savings using your latest electricity bill.
What is the payback period on a VoltX™ Neovolt system?
For a single-phase system priced around $5,300–$5,800 installed with the federal rebate applied, and annual savings of $1,000–$1,500, payback typically lands between four and six years — well within the 10-year warranty.
Do I need solar panels to benefit?
Solar delivers the biggest savings, and the federal Cheaper Home Batteries rebate requires an existing or connected solar system. That said, the battery can still time-shift cheap off-peak grid power to peak periods. If you don't have solar yet, VoltX Energy can arrange solar and battery together.
How does the battery work with my solar feed-in tariff?
Instead of exporting excess solar for a small feed-in payment (often just 3–5c/kWh), the system stores that energy so you can use it at night and avoid buying grid power at 30–45c/kWh. Storing your solar is usually worth many times more than exporting it.
What warranty and lifespan can I expect?
Every VoltX™ Neovolt system includes a 10-year battery warranty and a 10-year inverter warranty, both supported directly by VoltX Energy. The battery is rated for 10,000 cycles, supporting an expected service life of around 20 years.
