Off-Grid EV Charging Stations Integrated Energy Storage Solution

Background

South Africa frequently experiences power outages due to its weak grid infrastructure. However, the country has abundant solar resources. To address the growing demand for electric vehicle (EV) infrastructure, MagicPower partnered with local South African companies Zero Carbon Charge and Greencore Energy Solutions to develop an off-grid energy solution. This R1 billion project aims to establish 120 solar-powered, off-grid EV charging stations, reducing dependence on the grid and utilizing solar energy.

Challenge

The primary challenge was transitioning from grid-dependent charging systems, common in many regions, to a fully off-grid model that could operate independently of South Africa's unstable power grid. The goal was to create a reliable, scalable solution that could support the mass adoption of EVs in areas where the grid was either weak or non-existent. Additionally, the project faced several technical challenges during construction, including unstable busbars, system reliability issues, and the slow startup speed of new diesel generators, which were critical for backup power.

Solution

 MagicPower upgraded conventional systems to a purely off-grid solution. The project features:

• Expandable 250 kW PCS

• Battery Energy Storage System (BESS) Capacity: 558 kWh

• Charging Output: Up to 480 kW

• Three Charging Points per Station

These enhancements ensured stable, efficient operation in weak grid areas. The first two pilot stations are now operational, offering a model for future deployments.

Conclusion

This project not only provides a scalable and sustainable solution for South Africa's growing EV market but also serves as a reference model for other regions with weak grid infrastructure. The successful implementation of the first two pilot stations showcases the potential of off-grid solar-powered EV charging systems to reduce reliance on fossil fuels and alleviate pressure on the national grid. Over the next five years, MagicPower will expand this network, focusing on urban and highway areas, driving renewable energy adoption and supporting the EV transition across South Africa.
