According to the latest 2025 data from SunWiz, an independent solar and energy consultancy, Sigenergy has secured the No.1 position as the top energy storage brand in South Africa’s 0–1000 kWh energy storage system (ESS) market. This achievement is supported by strong market performance and deep trust from local installers.
SunWiz’s analysis highlights Sigenergy’s outstanding performance across key metrics: over the past 12 months, the brand has claimed the No.1 spot in both market share by kWh and by system count. Additionally, demonstrating consistent dominance rather than short-term momentum, Sigenergy has maintained its No.1 ranking for total installed kWh for four consecutive quarters. A key driver of this leadership is Sigenergy’s exceptionally high installer depth, reflecting that installers who choose Sigenergy allocate a large portion of their portfolios to the brand, underscoring strong confidence in the product’s performance and value.
At the core of this trust lies Sigenergy’s energy storage systems: engineered with industrial-grade reliability, seamless 0ms switchover for uninterrupted power, and a modular, scalable design that adapts to growing energy demands, they perfectly align with South Africa’s dynamic industrial and commercial needs.
This South African milestone aligns with Sigenergy’s global leadership, as the brand also holds No.1 rankings in major markets like Australia and Ireland. Globally, Frost & Sullivan named Sigenergy No.1 in the stackable all-in-one Distributed Energy Storage System category, with 475 MWh shipped in 2024, cementing its global sector leadership.
Founded in 2022, Sigenergy has quickly become one of the industry’s fastest-growing companies, with South Africa as a key high-performing market. Its regional success stems from a focus on innovation, product reliability, and an installer-centric design, all of which are critical to thriving in South Africa’s dynamic energy transition.
Sigenergy continues to collaborate closely with local installers and partners to support the widespread adoption of solar and energy storage solutions across South Africa, empowering homes and businesses with greater energy independence and resilience.
