The Clean Energy Council has now approved three Sigenergy commercial and industrial inverter families in Australia. This means the products can be used in commercial solar and hybrid energy projects. Buyers can also order with more confidence, knowing the products meet Australian safety and performance standards.
This update is important for businesses planning new solar installations, storage upgrades, or hybrid microgrid systems. It also helps consultants and EPC teams who need equipment that meets standard compliance and procurement requirements.
What Does the CEC Listing Mean?
The Clean Energy Council listing is a public approval list for clean energy equipment in Australia. It gives commercial buyers a quick way to check if an inverter is part of the approved products.
CEC approval makes the early stages of a project simpler.
- It reduces paperwork risk because the inverter already appears on the approved list.
- It reduces design churn because the team can lock in equipment sooner.
- It reduces procurement risk because the listing signals the product is ready for deployment.
CEC approval also affects project timing. A listed inverter can be used in project planning right away. A non-listed inverter causes delays and extra checks, often during engineering review, grid connection, and commissioning.

Which Sigenergy Products Gained Approval by the CEC?
The approval includes three product groups, each offering the same size options.
- PV Inverters: 50 kW, 99.9 kW, 110 kW, 125 kW
- HYA Hybrid Inverters (on-grid): 50 kW, 99.9 kW, 110 kW, 125 kW
- HYB Hybrid Inverters (on-grid and off-grid): 50 kW, 99.9 kW, 110 kW, 125 kW
A PV inverter is used for solar generation. It converts DC electricity from solar panels into AC electricity for use onsite or for export.
A hybrid inverter manages both solar and battery operations in one system. It controls solar generation and coordinates battery charging and discharging.
The HYA models target on-grid use. That means the system runs while connected to the grid.
The HYB models work for both on-grid and off-grid use. This means the system can operate without the grid when needed. This setup is often called a microgrid, where local generation and storage supply local needs, with or without the main grid.

What Sigenergy C & I Inverters Can Do
Sigenergy describes this commercial and industrial range as “future-ready” and flexible. The main design feature is a DC-coupled platform.
A DC-coupled design links the solar and battery on the DC side of the system. This setup makes it easier to add storage later, since the inverter is already designed for battery connections.
Sigenergy says the platform allows sites to add energy storage at any time without changing the original system. This addresses a common issue for businesses that start with solar and add storage later as needs or costs change.
Sigenergy also mentions a compact design and easier installation, which help lower system costs and make commissioning smoother. The company highlights an integrated EMS, or energy management system, which controls when to use solar power and when to charge or discharge the battery.
SigenStack combines hybrid inverters with 12 kWh battery modules. Each inverter can scale up to 253 kWh, and up to 100 inverters can work in parallel, allowing system sizes up to 25 MWh.
Those numbers matter to commercial buyers because they show two ways to scale the system: increasing the on-site storage capacity and increasing power and system scaling.
Parallel inverters increase the system’s overall capability to serve larger loads and larger sites.
Buyers can use this setup to match equipment to their goals.
- A business that needs longer runtime during peak periods needs more energy capacity.
- A business that needs higher site power support needs more inverter capacity and more parallel units.

Safety and Operational Features for the Sigenergy C & I Update
The update lists several safety and operational features for the system.
Sigenergy highlights six-layer battery protection, fast anti-backflow protection, and intelligent arc-fault detection with response times of up to 500 milliseconds.
Anti-backflow protection is important when a site wants tight control over exports. Some sites need zero export. Some sites need export caps. Some sites want to avoid reverse power flow during certain operating modes. Fast control reduces the risk of operating outside agreed limits.
Arc fault detection is important because arcs cause heat and risk. The speed of detection matters, as faster response can prevent a small fault from becoming a bigger problem.
The update also mentions an IP66 rating, which shows strong protection against dust and water. This is important for commercial sites that install equipment outdoors or in areas with dust, spray, or cleaning risks.
Sigenergy also points out the full remote monitoring and fast commissioning. These features address common operational challenges.
- A team wants remote monitoring because it shortens fault diagnosis time.
- A team wants rapid commissioning because it reduces time on site and delays.

What Commercial Buyers Should Do with This Information
This update gives commercial buyers a clear signal. Sigenergy now has a CEC-listed C&I inverter range in Australia, and the range aligns with modular storage through SigenStack.
A commercial buyer can use this information in a simple evaluation workflow.
- Confirm the project type. The project can be solar-only, solar plus storage, or solar plus storage with off-grid capability.
- Match the inverter family to the operating mode. PV inverters match solar-only sites.
- HYA hybrids match on-grid hybrid sites. HYB hybrids match sites that need on-grid and off-grid capability.
- Match the size options to the site plan. The range includes 50 kW through 125 kW units.
- Map the storage path if the project uses SigenStack. The design scales with 12 kWh modules, scales per inverter up to 253 kWh, and scales across inverters up to 100 units.
This approach keeps the selection grounded in outcomes. It also keeps the conversation focused on practical constraints, such as site loads, operational goals, and staging plans.

Wrapping Things Up: CEC You Soon
CEC approval makes it easier for commercial buyers to choose Sigenergy’s commercial inverters in Australia. This approval removes a key product barrier and helps simplify compliance. However, a successful project still needs the right site design, network approvals, and proper commissioning.
At PSC Energy, we recommend the Sigenergy product line. We design systems to match each site’s load profile and operating goals, and we plan for export limits and battery options, whether now or in the future. It’s what we do.
