Commercial Solar Solutions
Commercial Battery Storage Systems (BESS)
Cut electricity costs by storing solar power, maximise your commercial solar self-consumption, and secure backup power when the grid lets you down.
#Commercial battery storage rebates are changing in May 2026
If you're considering a larger commercial battery, timing could affect your upfront discount and payback. Get your system sized now so you can make a confident call.
Unlock the Benefits of Commercial Battery Storage
Investing in a Battery Energy Storage System (BESS) can transform your energy strategy—cutting costs, protecting operations, and opening new revenue streams.
We design and install commercial battery storage (50kW–250kW+). Reduce demand charges, store excess commercial solar power, and secure backup energy—tailored to your site's specific load profile.
Whether you're looking to save money by reducing demand charges, increase solar self-consumption, or explore energy arbitrage—commercial BESS is the solution.
$0 Upfront Finance Options Available
Prefer to preserve capital? Our chattel mortgage and lease options mean you can install commercial battery storage with no deposit and start saving immediately. Many businesses are cashflow positive from month one as energy savings exceed repayments. Subject to credit approval.
Overview
#Which Best Describes Your Situation?
Whether you're adding to existing solar or starting from scratch, we can design the right battery storage solution for your business.
Already Have Solar?
Add Battery Storage
Retrofit an AC-coupled commercial battery storage system to your existing setup. Store excess daytime power instead of exporting it to the grid.
Starting Fresh?
Solar + Battery Together
Install a new DC-coupled commercial solar and battery system. Higher efficiency with integrated monitoring and faster payback.
#How Commercial Battery Storage Saves and Adds Value
Want the battery designed to match your solar generation and operating hours?
Reduce Demand Charges
By storing low-cost solar or off-peak grid power, our commercial battery storage systems flatten your load profile and reduce the demand charges that make up 40-60% of your electricity bill.
Maximise Solar Self-Consumption
Sending excess commercial solar power back to the grid earns you nothing. Our BESS solutions capture that energy for later use, increasing your solar self-consumption from 60% to 90%+.
Long-Term Reliability & Safety
Our commercial battery installations are AS/NZS 5139 compliant, with a 15+ year design life and thermal protection for safe operation in Australian conditions.
Backup Power & UPS Capability
Power outages cost thousands per hour. A commercial battery provides seamless backup power and UPS capability for critical circuits, keeping you online when the grid fails.
#Compare System Sizes – See What Fits Your Business
Battery sizing depends on your operating hours, peak demand periods, and the size of your commercial solar panels or existing system.
Not sure what size you need? We’ll recommend a battery size based on your bill, site load profile, and energy goals.
| 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 evening costs |
| 250–500 kW | Warehouses, retail, logistics | $40k–$90k | 2–3 years | Optimise solar, cut demand charges |
| 1 MW+ | Manufacturing & enterprise | $100k+ | 1.5–2 years | Full energy management, backup power |

#Ready to Start Saving? Let’s Talk Battery Storage.
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 commercial solar you're using versus exporting, and what you want the battery to achieve—savings, resilience, or both.
#FAQs About Commercial Battery Storage
A BESS is a Battery Energy Storage System—an industrial-grade rechargeable battery setup that stores electrical energy for your business.
Unlike residential Powerwalls, commercial BESS units range from 50kW to 250kW+ and use LiFePO4 (Lithium Iron Phosphate) chemistry for safety and longevity.
They store excess commercial solar power or off-peak grid energy, then discharge it during high-rate periods or outages.
It can be—especially where 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, which we can review to confirm suitability.
It depends on what you want the battery to do. Savings-focused systems are sized around kW (power) and kWh (capacity); resilience-focused systems are sized around your critical loads. We'll recommend based on your usage profile and commercial solar generation.
kW (kilowatts) is power—how much equipment the battery can run at once. kWh (kilowatt-hours) is capacity—how long the battery lasts. We size commercial BESS based on both your peak load and desired runtime.
Yes. Batteries can supply power during short high-demand events and reduce the maximum demand recorded for billing, which may lower demand charges depending on your tariff.
It can support backup power for selected circuits when designed with UPS capability. We'll help you identify critical loads and confirm runtime expectations.
Yes. AC-coupled battery retrofits work well with existing commercial solar systems. We confirm inverter compatibility and configure for maximum solar self-consumption.
Yes. Standalone BESS can perform energy arbitrage—charging from the grid during off-peak time-of-use rates and discharging during high-cost periods.
Incentives vary by state. For the latest on commercial battery storage rebates, including the Instant Asset Write-Off, refer to the Australian Government’s Cheaper Home Batteries Program — and we can talk you through what may apply to your business.
Most LiFePO4 commercial battery systems are designed for 15-20 years with 6,000+ cycles. Warranties typically specify performance retention—we'll explain expected life based on your proposed cycling.
