In April 2025, the well-known household energy storage brand partnered with our company has fully completed the technical upgrade from off-grid to grid-connected mode, successfully delivered compliant samples to relevant regulatory authorities in South Africa, and formally signed a household energy storage installation cooperation contract with a senior local agent in South Africa. This move marks the company's accurate grasp of the policy opportunities in South Africa's electricity market and further deepens its strategic layout in the core energy storage market of Africa.
As a leader in Africa's energy storage industry, South Africa has become a key layout area for global household energy storage enterprises in recent years due to issues of power supply stability and the demand for energy transition. The implementation of South Africa's Integrated Resource Plan and the amendment to the Electricity Regulation Act in 2025 not only simplified the grid-connection permit approval process, but also introduced a surplus electricity feed-in credit mechanism, allowing household users to gain benefits by injecting excess electricity into the grid, which has greatly stimulated the market demand for grid-connected energy storage products. At the same time, Eskom (South African Power Utility) has abolished the strict requirement for approval signed by ECSA-registered engineers, and instead allows systems to be approved by labor department-registered electrical practitioners, reducing the connection cost of a typical 16kVA system by more than 9,000 Rand and significantly lowering the popularization threshold of household energy storage.
The grid-connection upgrade completed this time is highly in line with South Africa's core grid-connection standards such as NRS 097-2-1, RPPS and BESF, and focuses on strengthening three major technical advantages. First, an intelligent dual-switch control system is adopted, which can complete grid fault detection and mode switching within 10 milliseconds to achieve seamless connection between grid-connected and off-grid states. This not only ensures the peak-valley arbitrage income when the grid is normal, but also guarantees the continuous power supply for key household appliances during power outages. Second, the performance of the energy storage converter is optimized, increasing the power conversion efficiency to over 98%. At the same time, the pre-synchronization technology is used to accurately match the grid voltage and frequency, avoiding the risk of current impact during the switching process. Third, an upgraded Battery Management System (BMS) is equipped, which can monitor the battery status in real time and automatically adjust the charging and discharging strategy according to the characteristics of South Africa's peak-valley electricity prices to maximize the user's economic benefits.
To ensure that the products fully meet the market access requirements of South Africa, the company has strictly followed the local certification process, completed comprehensive tests including power output, grid compatibility and safety protection, and submitted complete technical documents and test reports to the regulatory authorities. The compliant samples delivered this time cover the mainstream capacity range from 10kW/10kWh to 8kW/16kWh, which can meet the electricity demand of households of different sizes, and are especially suitable for the common rooftop photovoltaic supporting scenarios in South African households.
In terms of market channel expansion, the South African local agent signed this time has a complete offline service network and a professional installation team, with NRCS certification guidance capabilities and a localized after-sales response system. The energy storage products it represented previously have accumulated a good reputation in the South African market. According to the cooperation agreement, the two parties will establish a joint inventory mechanism to realize rapid product delivery relying on local warehousing. At the same time, the agent will provide a full-chain service from on-site survey, compliant installation to after-sales maintenance, ensuring that users enjoy a service experience of "compliant upon installation and worry-free upon use".
With the accelerated transition to clean energy in Africa, South Africa has formed a commercial and industrial energy storage scale of 3.2GW, and the household energy storage market is on the eve of an outbreak. The implementation of our company's grid-connected product upgrade and local cooperation this time will not only help more South African households achieve independent electricity consumption and cost optimization, but also inject practical momentum into the local clean energy transition. In the future, the company will continue to iterate its products according to market feedback, explore advanced applications such as Virtual Power Plants (VPP), and grow together with the South African market.
