Big News for Australian Businesses
Sigenergy's commercial and industrial (C&I) battery storage system, the SigenStack, has officially been approved for installation in Australia as of April 20th, 2026. This marks a significant milestone for businesses looking to reduce energy costs and improve operational resilience through advanced battery storage technology.
What is SigenStack?
The SigenStack is Sigenergy's commercial commercial battery storage solution designed for medium to large scale businesses. Unlike residential battery systems, the SigenStack is engineered for the higher demands of commercial operations handling larger energy loads, enabling peak shaving, and providing robust backup power during grid outages.
Technical Specifications
Inverter Range (CEC Approved in Australia)
- 50kW, 60kW, 80kW, 100kW, 110kW, and 125kW hybrid inverters
- Approved for commercial solar and storage projects
- Smallest and most compact 110kW hybrid inverter in its class
Battery Capacity
- 12kWh battery modules (stackable)
- Up to 253kWh per single inverter
- Up to 100 inverters can be paralleled
- Maximum system capacity: 25MWh (25,000kWh)
This modular design means you can start with a system sized for your current needs and scale up as your business grows without replacing existing infrastructure.
Key Features That Matter for Your Bottom Line
Peak Shaving
Store energy during off-peak hours and discharge during peak demand to dramatically reduce demand charges often 30 to 60% of your electricity bill.
Scalable Capacity
From small retail stores to multi-megawatt warehouse systems. Grow as you need without infrastructure replacement.
Solar Integration
Maximize energy consumption by storing excess solar generation during the day and using it during peak hours.
Backup Power
Seamless backup during outages ensures critical operations continue without interruption.
Smart Energy Management
Advanced EMS optimizes charging and discharging based on real-time pricing, solar, and consumption patterns.
Modular & Expandable
Start small, scale up. The modular design allows seamless capacity additions without replacing existing systems.
Why This Matters for Australian Businesses
Rising Energy Costs & Demand Charges
Australian businesses have seen electricity costs increase significantly over the past decade. Demand charges fees based on peak power usage can account for 30 to 60% of a commercial electricity bill. SigenStack directly addresses this by reducing peak demand through intelligent battery dispatch.
Sustainability & ESG Goals
Many Australian businesses are setting ambitious carbon reduction targets. Combining solar with battery storage allows companies to maximize renewable energy usage, reduce emissions, and demonstrate environmental leadership to customers and stakeholders.
Strong ROI in 3-7 Years
Commercial battery systems typically achieve ROI within 3-7 years through:
- Reduced demand charges (biggest savings for most businesses)
- Lower energy bills via time-of-use optimization
- Avoided downtime costs from outages
- Government incentives and depreciation benefits
Who Should Consider SigenStack?
SigenStack is ideal for:
- Manufacturing facilities with high daytime energy consumption
- Warehouses and logistics centers with large roof space for solar
- Retail and shopping centers looking to reduce operating costs
- Office buildings with predictable energy patterns
- Cold storage facilities requiring 24 hour reliable power
- Data centers needing uninterrupted backup power
Why Sigenergy?
Sigenergy has rapidly become a leading player in energy storage, known for:
- High-quality lithium iron phosphate (LFP) battery technology
- top warranties (10+ years)
- Advanced monitoring and control systems
- Strong local support in Australia
The approval of the C&I SigenStack range in Australia is a natural progression following the success of their residential systems (Sigenergy 5 and Sigenergy TL3), which have been well-received on the Sunshine Coast and across Queensland.
