From March 25 to 27, 2026, Solar & Storage Live Africa—the continent’s largest renewable energy exhibition—kicked off grandly at the Gallagher Convention Centre in Johannesburg, South Africa. SAJ Electric made a high-profile appearance with its full range of PV energy storage and industrial automation products at Booth F30, Hall 5, exploring new opportunities for green energy development in Africa alongside global industry peers.
South Africa is accelerating its energy transition to end long-standing power shortages. The government has rolled out a nearly $130 billion energy transition plan, with a clear target to raise solar photovoltaic power generation to 18% by 2039, signaling huge potential in the distributed PV energy storage market. With 21 years of industry expertise, SAJ Electric has tailored PV energy storage and industrial automation solutions to South Africa’s local conditions. At the exhibition, its newly launched commercial & industrial CH3+CB3 energy storage system and core industrial automation product PDS33 garnered massive attention.
At the exhibition, SAJ Electric showcased two core business segments in full, with products finely adapted to South African market demands and packed with standout features.
Covering residential, commercial & industrial (C&I) PV energy storage and smart energy management, the portfolio fully meets diverse energy needs.
CH3 Series 125kW Hybrid Inverter
As the world’s first C&I distributed hybrid inverter built on a 1500V DC voltage platform, its elevated voltage allows 50% more PV panels per string compared to traditional 1000V systems, cutting string connections by 30%. This substantially reduces upfront costs for PV brackets, DC cables and other components. Supporting parallel operation from a single unit to ten units without external transfer switches, it enables seamless on-grid to off-grid switching in less than 20ms, ensuring uninterrupted power for critical industrial processes during grid outages. As a flagship model for C&I PV energy storage scenarios, its high-power output and scalability cater to heavy-duty electricity demand in factories, commercial establishments, industrial parks and more. With 200% PV overloading capability, it maximizes solar resource utilization while supporting high-power PV modules, balancing efficiency and cost control to help C&I users cut costs, boost efficiency and achieve fast return on investment.
CB3 Battery System
Featuring a modular design with optional air or liquid cooling, the system offers flexible expansion to fit diverse C&I scenarios. Equipped with high-performance battery cells, it delivers long cycle life and stable charging/discharging efficiency, supporting on-demand modular expansion for applications ranging from small retail outlets to large factories. The two cooling modes can be flexibly selected based on site conditions and load profiles. Boasting exceptional high-temperature resistance, it operates reliably even in South Africa’s extreme heat, forming a high-efficiency energy storage closed loop with inverters to ensure stable 24/7 power supply for commercial and industrial users.
CH2 Series 50kW Hybrid Inverter
Ranging from 29.9kW to 50kW, the CH2 Series supports seamless on/off-grid switching and direct diesel generator connection, ideal for small to medium-sized C&I projects. Custom-designed for South Africa’s small and medium factories, shops and office spaces, its interruption-free switching safeguards power continuity, preventing production halts and equipment damage from blackouts. Multi-unit parallel operation allows flexible matching with the electricity needs of various small and medium commercial operators.
Targeting persistent voltage instability and sudden blackouts in parts of South Africa, SAJ Electric launched a residential PV energy storage solution centered on the H2 hybrid inverter and B3 energy storage battery. Available in single-phase and three-phase variants, the H2 Series flexibly adapts to different household electricity demands. With millisecond-level on/off-grid switching, the H2 inverter works seamlessly with the B3 battery to take over critical loads instantly during outages, ensuring stable household power. Notably, it also supports connection to diesel generators as a backup power source, providing multi-layered power security for households during prolonged blackouts or extended cloudy periods when stored energy is low. Engineered for South Africa’s hot, dry summers, the equipment operates stably at temperatures exceeding 50°C, with an enclosure rating built for harsh outdoor conditions—high-temperature resistant and drought-tolerant for superior practicality and durability. Additionally, the system enables intelligent energy monitoring and load management, allowing users to optimize household electricity usage with precision. Unveiled at Solar & Storage Live Africa, this solution offers South African households a stable, reliable and scalable residential energy storage option.
Higher Returns: Integrated with AI Saving 2.0, it lifts overall energy revenue by an average of 35%, adapting to complex electricity usage scenarios.
Intelligent Dispatching: Boasts over 90% accuracy in power generation forecasting and generates power usage schemes in seconds for efficient energy allocation.
Simplified Management: Intuitive visual interface supports system diagnostics and power station monitoring, helping users maximize the value of their electricity consumption.
PDS33 Solar Water Pump Controller
High Efficiency & Energy Saving: Achieves 99.8% MPPT efficiency to maximize solar energy utilization, accurately tracking light intensity changes. Leveraging South Africa’s abundant solar resources, it operates independently of the grid, drastically cutting electricity costs for agricultural irrigation and industrial water supply in an eco-friendly and cost-effective manner.
Wide Compatibility: Supports single-phase AM and PMSM motors and is compatible with various pump models, perfectly meeting diverse water needs in South Africa including agricultural irrigation, livestock water supply and industrial water intake, with strong versatility for local applications.
Smart Control & Management: Features automatic start/stop for unattended operation; supports optional 4G modules for remote monitoring; zero-programming design enables one-step installation and commissioning for ease of use. Equipped with multiple circuit protections, it guards against voltage fluctuations, lightning strikes and other risks, ensuring minimal maintenance costs and long-term stable operation.
Moving forward, SAJ Electric will continue to deepen its presence in South Africa and across the African market, focusing on local energy transition pain points and development needs. The company will further cultivate its two core segments—new energy PV energy storage and industrial automation—by continuously advancing technology, upgrading products and optimizing services. With reliable green energy solutions, SAJ Electric aims to help Africa resolve power challenges, drive low-carbon upgrades to its energy structure, empower the continent’s clean energy growth with cutting-edge technology, and join global partners in forging a new low-carbon, green future.
