From large corporations to micro, small and medium-scale enterprises (MSMEs), energy stability is essential for productivity and business growth. As industry leaders in Africa are preparing for the green energy transition, making low-carbon energy solutions for increased productivity at lower cost is of utmost importance.

Sub-Saharan Africa has an average of five hours of power outages a day. By comparison, South Asia loses power for about two hours while high-income countries lose less than an hour a day. This not only negatively impacts productivity and manufacturing in Africa, but also long-term productivity and job security for a continent rife with unemployment.

“We understand the predicament of business leaders on the continent. As an innovator in photovoltaic (PV) and energy storage solutions (ESS) we offer a range of industry-leading products to help companies meet their targets and stay ahead of competitors,” says Huawei Digital Power South Africa C&I Solutions Architect Muzakkir Sonday.

Huawei introduced its commercial and industrial (C&I) smart PV and battery energy storage solutions (BESS) to the African market with the future of energy in mind. The Model LUNA2000 200 kWh-2H1 is a high-capacity smart-string BESS that delivers superior performance and can be scaled up to 4 000 kWh.

“Our C&I smart PV solution is an integrated solution for PV, BESS, optimiser and cloud management. It puts businesses in control by providing a one-stop solution for all scenarios and load ranges,” says Sonday.

In South Africa studies show that advancing renewable energy capacity, along with energy storage and solutions that promote efficiency, are the most appropriate pathways to enabling economic growth. Here is how Huawei solutions reliably provide scalable solutions so African businesses can unlock this growth.

Features for Reliable Energy Provision

Safety and reliability lie at the core of Huawei’s PV and ESS systems. These solutions are developed to ensure energy stability while simplifying operations and maintenance (O&M).

Its systematic design means businesses of all scales and from a broad range of industries can easily adopt the solution into their ecosystem.

Energy storage components of the ESS are put through reliability testing for eight months to ensure that only high-quality battery cells are used. They reliably work in altitudes of up to 4 000 m.

Artificial intelligence- (AI-) based optical storage optimisation increases revenue by 10%. Reliability is enhanced through pack-level optimisation that promotes balanced charging and discharging which prolongs the battery system’s life span.

An integrated solution, suitable for a diverse range of businesses and operations

The Model LUNA2000 200 kWh-2H1 is ideal for farms, office parks, petrol stations, factories or banks that need versatile power solutions.

“Businesses in Africa can take advantage of the system's renewable energy integration - it can store grid, solar or wind-generated excess energy and deliver it when needed.”

For larger scale solar energy applications, Huawei’s smart optimiser Model MERC-1100/1300W-P, ensures that solar modules operate at an efficiency of 99.5% so businesses get the most from their solar module yield.

“The system’s backup power supply capabilities will also help businesses ensure continuous operations during outages,” says Sonday.

Newly Launched SUN2000-150K & SUN5000-150K Inverters

Inverters can be thought of as the neural centre of a PV system because they determine energy generation as well as efficiency and safety.

The C&I offering from Huawei consist of a range of integrated solutions, including the ESS system Model LUNA2000 200 kWh-2H1, the newly launched SUN2000-150K & SUN5000-150K inverters and PV optimisers. Together these products create a solution that provides a consistent energy supply that can be used alongside energy grids to support load shifting and respond to shifting energy demands.

These all-round high-powered inverters are developed on an all-new V6 platform that produces a maximum power output of 165 kW and reaches a maximum efficiency of 98.8%. It is equipped with safety features like active disconnect and similarly to the rest of Huawei’s C&I solutions, these inverters are designed with reliability, simplified O&M, optimal BOS and grid adaptability in mind.

The integrated solution with the Smart String PV inverters and ESS systems allows for uninterrupted power in remote regions or cities with unreliable power – bringing productivity to the most rural areas.

Features for Safe Energy Provision

“Huawei’s ingenious approach to safety makes O&M a breeze, and gives enterprises peace of mind,” says Sonday. “Smart cell-level monitoring is enabled through AI which identifies battery risks and isolates faulty racks on demand. These features reduce the need for site visits and lower O&M costs.”

The Model LUNA2000 200 kWh-2H1 BESS & 150K inverters seamlessly work with Huawei’s cloud-based battery management system which tracks battery cell data in real time. It is fitted with intelligent string disconnection protection, which disconnects DC power in milliseconds should the inverter experience failure like an internal short circuit or PV string reverse connection.

Further, faults like high system temperatures, external force deformations or battery penetration are identified in advance and warn users about potential thermal runaway.

Smart PV ground-fault protection cuts off ground faults within 15 milliseconds during the grid connection process, reducing the chances of inverter failure by more than 75%. Intelligent terminal temperature detection monitors AC and DC terminal temperatures and should there be any overheating, it shuts down within 0.5 seconds to prevent inverter failure or burning of the DC terminals.

Meeting Tomorrow’s Energy Needs, Today

Huawei solutions are not just geared to help businesses meet their current energy needs, they are also future-proof thanks to their compatibility with other green energy sources, which are becoming increasingly important.

“More than 100 000 businesses around the globe rely on our solutions for their energy needs. We are also there to help them transition to a green and low-carbon future, having saved 42-million tons of carbon to date. At the end of the day our C&I line is geared towards powering up your business,” concludes Sonday.
