According to market data from SunWiz, the manufacturer is the largest supplier of energy storage in Australia, Ireland and South Africa.
According to recent market data from independent solar and energy storage consultancy SunWiz, Sigenergy has become the number one energy storage provider in several international markets, including Australia, Ireland and South Africa.
In these regions, SunWiz figures show that Sigenergy has the highest market share for energy storage systems, reflecting widespread adoption by installers and growing demand downstream. Data shows that the manufacturer has the largest installer reach and installer depth in Australia, Ireland and South Africa, meaning its systems are not only used by a broad base of installers, but are also repeatedly deployed on a significant portion of their projects across the residential and commercial segments.
Australia has become one of Sigenergy’s strongest global markets. Since March 2025, the company has maintained the top position in the field of blended battery capacity for ten months in a row, partly thanks to its integrated system approach. In the residential and small commercial segments, the company’s SigenStor combines the inverter, battery, PCS, energy management system and EV charging into a single modular architecture. The modular design makes the SigenStor flexible and scalable and has a battery capacity of 5 kWh, 6 kWh, 8 kWh or 9 kWh. A single SigenStor unit provides up to 54 kWh, and in a parallel connection this can support up to several hundred kWh.
For larger commercial and industrial projects, Sigenergy offers SigenStack, a modular and scalable energy storage system designed for higher capacity deployments. A single SigenStack inverter has a capacity between 48 kWh and 252 kWh. The company says additional inverters and batteries could be installed to increase capacity, noting that Sigenergy has a project in Bulgaria with a capacity of 20 MWh. When combined with Sigen Gateway, the platform also supports seamless switching on the load side, enabling immediate backup power during grid outages, especially in regions where grid stability and electricity price volatility remain important considerations.
In addition to hardware, Sigenergy is positioning its portfolio as a software-defined, AI-enabled energy platform. AI algorithms optimize charging and discharging strategies, predict charging and generation patterns, and support continuous monitoring of system status for all deployed assets.
Virtual Power Plant (VPP) functionality in both SigenStor and SigenStack is already actively used in markets such as Sweden, the Netherlands, Germany and Australia, allowing distributed installations to be aggregated and coordinated in response to grid signals and market mechanisms. For end users, Sigenergy says this will enable more efficient energy use, greater participation in network services and access to additional value streams where market frameworks allow. This software-centric approach underlines the company’s long-term focus on intelligent, flexible and grid-interactive energy solutions.
At a global level, Frost & Sullivan ranked Sigenergy number one worldwide in the stackable all-in-one distributed energy storage systems category in 2024, with a transmission capacity of 475 MWh and a 28.6% share of the global market.
