Take Control of Energy Costs — and Your Bottom Line
Battery storage helps your business use energy on your terms. By storing energy when it’s cheaper (from solar or off-peak grid periods) and using it when prices rise, batteries can reduce exposure to peak tariffs and demand charges — while supporting more predictable operating costs.
Whether you’re looking to get more value from an existing solar system, planning a new commercial solar + battery installation, or exploring backup power for critical loads, we’ll help you design a battery solution that fits your site, usage profile, and business priorities.
#How Battery Storage Saves (and Makes) You Money
Manage Demand & Reduce Peak Charges
Many businesses pay not just for energy used, but for how high demand spikes during peak periods. Battery storage can reduce those spikes by supplying power when your site demand surges, helping lower demand charges and peak tariff impacts.
Maximise Solar Self-Consumption
If your business exports excess solar during the day and buys power again later, a battery can store that surplus solar and use it after hours - improving your solar utilisation and reducing reliance on grid power.
Protect Operations During Outages (Backup Power)
For sites where downtime is costly, batteries can support selected critical circuits during outages (e.g., networking, POS, refrigeration, access control, lighting). We’ll help you define what needs to stay on and design around it.
Reduce Generator Runtime & Fuel Costs (Where Applicable)
For businesses that rely on diesel generators for backup, battery storage can reduce generator runtime by carrying loads during short interruptions and smoothing peaks - cutting noise, emissions, and fuel use in the process.
Support Sustainability Reporting (Scope 2 Emissions)
Battery storage can increase renewable energy usage on-site and reduce grid consumption during high-emission periods. For businesses tracking ESG or energy performance, batteries can be part of a practical, measurable improvement plan.
Smarter Energy Strategy Over Time
Battery opportunities vary by site, tariffs, and operational profile. The best results come from matching the battery size and controls to how your business actually uses energy — not from a one-size-fits-all approach.
#Compare System Sizes - See What Fits Your Business
Battery sizing should reflect how your site operates: when you use energy, whether you have solar, your peak demand profile, and what you want the battery to achieve (savings, resilience, or both).
Use the guide below as a starting point - then we’ll confirm the best-fit system size during an assessment.
| System Size | Ideal For | Typical Annual Savings | Payback Period | Example Benefit |
|---|---|---|---|---|
| 50–100 kW | Small businesses, cafés, offices | $10k–$25k | 3–4 years | Store excess solar, reduce peaks |
| 250–500 kW | Warehouses, retail, logistics | $40k–$90k | 2–3 years | Optimise solar, lower grid draw |
| 1 MW+ | Manufacturing & enterprise sites | $100k+ | 1.5–2 years | Power stability, huge ROI gains |

#Battery Rebates & Incentives
Battery incentives can change by state and eligibility. For the latest official details, see the Cheaper Home Batteries Program (official Australian Government information). Eligibility can depend on your site type, system size, and how the battery is configured with solar. Don’t worry — we’ll talk you through what applies to your business and the best way to structure your system.

If you’d like pricing, a sizing recommendation, or a quick assessment of whether battery storage will stack up at your site, we can help.
As part of an initial assessment, we’ll look at what’s driving your energy bill, whether demand charges are influencing your costs, how much solar you’re using versus exporting, and what you want the battery to achieve — savings, resilience, or both.
#FAQs About Commercial Battery Storage
It can be — especially where peak tariffs or demand charges are a big part of the bill, where solar export is high, or where resilience matters. The best indicator is your interval data (or a recent bill + tariff), which we can review to confirm suitability.
It depends on what you want the battery to do. Savings-focused systems are sized around peak periods and demand spikes; resilience-focused systems are sized around your critical loads. We’ll recommend a size based on your usage profile, solar generation, and operating hours.
In many cases, yes. Batteries can supply power during short peak demand events and reduce the maximum demand recorded for billing, which may lower demand charges depending on your tariff and network rules.
It can support backup for selected circuits when designed that way. We’ll help you identify critical loads and confirm backup capability, runtime expectations, and any switchgear requirements.
Yes. Battery retrofits can work well, particularly if you export a lot of solar during the day and buy power again later. We’ll confirm compatibility and the best configuration for your existing system.
Incentives can vary by time, state, and eligibility. For the latest official information, refer to the Australian Government’s Cheaper Home Batteries Program — and we can talk you through what may apply to your business.
It varies by product, usage, and cycling patterns. Most systems are designed for long-term commercial operation, and warranties often specify performance over a number of years or cycles. We’ll explain the expected life and warranty terms based on your proposed use-case.
