Reliable energy independence is becoming an increasingly enticing option for homeowners, and the VoltX™ Neovolt On-Grid Battery stands out as the perfect solution to keep your home powered during outages. When the grid fails, it’s nice to know that this backup battery system can ensure you have power security, providing you with peace of mind when it’s needed most. Designed for top-tier performance and efficiency, this battery is ideal for anyone who wants to protect their home from unexpected power disruptions.
First, a Note on Backup Capability
One important thing to know before going further: not every VoltX™ Neovolt is set up to run your home during a blackout. A standard VoltX™ Neovolt installation stores solar energy and lowers your bills, but on its own it is not backup-capable. When the grid goes down, a standard system shuts down as well for safety.
Backup is an add-on. It requires additional hardware (such as an automatic changeover device) to island your home from the grid and keep essential circuits running during an outage, and it does add to the cost of the system. If blackout protection is the reason you’re considering a battery, tell us upfront so your system is quoted and configured accordingly. Everything that follows in this article—the outage protection, the “nights of backup,” emergency power—assumes a backup-capable VoltX™ Neovolt unit.
Capacity, Expandability, and What It Can Actually Run
Numbers matter when you’re choosing a battery, so here’s what the VoltX™ Neovolt gives you. Each module gives you around 9.6 kWh of usable storage, and the system is modular, so you can stack multiple modules to match your household.
Two stacked modules are roughly 19 kWh, three are 28 kWh, and larger configurations continue up from there. These are all managed through an inverter. Because it’s stackable, you can start with what suits you now and adds modules later as your energy needs grow.
What does that mean during an outage, assuming a backup-capable unit? A rough rule of thumb: a typical Australian home that runs only its essentials overnight—lighting, fridge, Wi-Fi, phone charging—draws far less than its all-day total, so even a single 9.6 kWh module can carry those essentials through a typical evening blackout, and stacked configurations extend across multiple nights. Pair the battery with solar and it recharges during daylight, stretching backup further still.
Exact runtime depends entirely on which appliances you run and your system’s configuration, so treat these as illustrations rather than guarantees—our team at VoltX Energy can size it to your actual usage.
Reliable Backup Power for Home Energy Security
The VoltX™ Neovolt On-Grid Battery is more than just a typical backup. It’s a smart, high-efficiency energy storage system that offers real energy security for your home. In the event of an outage, it steps in, delivering uninterrupted power to essential appliances and systems.
Thanks to its 200% backup overload capacity, even high-demand devices keep running smoothly, and with up to 98.4% max efficiency, it’s one of the most reliable and energy-efficient solutions for residential power storage.
Protect Your Home with Solar Battery Backup
If your home uses solar panels, the VoltX™ Neovolt On-Grid Battery makes an excellent addition to your system. During the day, solar energy is stored in the battery for use at night or during outage. This setup helps you reduce your reliance on the grid, increasing your energy independence.
The unit's advanced Battery Management System (BMS) and internal EMS optimise energy use, helping you save even more by tapping into stored energy during peak rate times. The PV production forecast feature also predicts energy production based on weather. Essentially, this smart system ensures you’re always prepared with enough stored energy.
Energy Security and Emergency Power Solutions
What really sets the VoltX™ Neovolt apart is its ability to protect your home during critical power outages. Its temperature monitoring and thermal management ensure the system runs reliably and safely, even in extreme weather. And with UPS-level protection, your essential devices stay powered without interruption.
In emergencies, it provides the backup power needed for essential circuits like lighting, refrigeration, and heating. Its grid-connected technology seamlessly transitions from grid powered to stored energy, making it a great solution for anyone looking to safeguard their home during outages.
Smart Energy Backup and Long-Term Reliability
The VoltX™ Neovolt isn’t just designed for short-term use. With a 10-year warranty and 10,000 life cycles, this system offers around 20 years of dependable service, without the constant worry of replacements or maintenance.

Frequently Asked Questions
How much usable capacity does the VoltX™ Neovolt have?
It’s modular, built from 9.6 kWh modules. Single-phase systems commonly start at 19 kWh and scale to 48 kWh. Because it runs at 100% depth of discharge, a 28 kWh system provides about 25 kWh of usable energy.
How long can the VoltX™ Neovolt power my home during a blackout?
For a typical home using around 20 kWh a day, a 28 kWh unit covers roughly 1.5 to 2 nights of essential use, a 38 kWh system around 2.5 to 3 nights, and a 48 kWh system 4+ nights. Pairing it with solar recharges the battery each day and extends that further. Actual runtime depends on your usage and which appliances you’re running.
Can I expand it later if my energy needs grow?
Yes. The VoltX™ Neovolt’s modular, stackable design means you can add modules to increase capacity as your household grows, rather than replacing the whole system.
Does the VoltX™ Neovolt keep working when the grid goes down?
If it’s configured for backup capability, yes. It seamlessly switches from grid power to stored energy during an outage, keeping your essentials running. Its 200% backup overload capacity handles high-demand devices at startup.
What warranty and lifespan does the VoltX™ Neovolt offer?
Every unit comes with a 10-year warranty on both the battery and inverter, and is rated for 10,000 life cycles, translating to roughly 20 years of dependable performance.
