What commercial batteries solve
Peak demand charges
Discharge during spikes to cap your maximum demand and reduce network and demand kW/kVA fees.
Time-of-use arbitrage
Store cheap solar/daytime energy and run your site through evening peak rates.
Blackout backup
Hybrid/AC-coupled battery with backed-up circuits keeps POS, lighting and servers online.
Power quality & control
Smooth loads, limit export and coordinate EV charging — all visible in a single monitoring app.

Right-size your battery for results
We analyse interval data and site loads to size kWh for your goals: demand shaving, TOU shifting, or backup runtime. Designs are installed to Australian standards (e.g., AS/NZS 5139), with clear commissioning and staff handover.

Commercial battery — FAQs
Will a battery reduce our demand charges?
Yes — when configured for peak shaving, batteries discharge during spikes to cap your maximum kW/kVA demand. Savings depend on your tariff and load profile; we model this with your interval data.
Hybrid or AC-coupled?
Hybrid is great for new or upgraded solar; AC-coupled suits retrofits with minimal PV changes. We’ll recommend the topology that best fits your switchboard, metering and export limits.
How long will backup last?
Runtime depends on battery kWh and the loads you choose to back up. We design “essential circuits” and estimate hours of autonomy for realistic expectations.
What about safety and standards?
Systems are designed and installed to Australian standards (e.g., AS/NZS 5139) with clearances, ventilation and signage. We complete commissioning, testing and staff handover.
Are incentives available?
Some programs may apply depending on system size and location. We’ll confirm any current incentives or schemes relevant to your project in our proposal.
