Polar Power Cube: Plug-and-play remote power monitoring with live cloud insights I n electrical installations, understanding If you roll out a new operating schedule or complete a maintenance fix, the historical log confirms whether it actually reduced your demand. The Power Cube doesn’t make those decisions for you, but it gives you the facts to make them. how electrical power behaves and is used is as crucial as safeguarding it. Traditionally, getting this information required installing a data logger, then making repeated site trips to manually retrieve readings, often delaying actionable insights.
Polar Monitoring’s Power Cube revolutionises this process. The device continuously measures your electrical supply and transmits live readings over a secure connection directly to the Polar Cloud. With this plug-and-play solution, you can view real-time performance data and analyse trends remotely, whether you’re on- site or across the globe. This instant access to accurate information enables faster, more informed decisions about your electrical systems, helping optimise efficiency, identify issues proactively, and reduce the need for costly site visits. Everything in one enclosure The Power Cube is a turnkey monitoring package: a Lovato DMG7500 power analyser and a Polar LTE gateway, already wired together inside one enclosure. The analyser measures the supply and displays the readings on the panel, while the gateway logs the data and sends it to the Polar Cloud. Fused terminals for the voltage inputs and terminals for the current transformer (CT) connections are already in place. The result is a single unit to mount, with the internal wiring already done. Connected where you need it Some of the sites that need monitoring most are the hardest to reach, and a trip just to read a meter isn’t always practical. The Power Cube has its own mobile connection (LTE/GSM), with a SIM managed by Polar Monitoring. Where the signal is weak, an optional high-gain antenna can improve reception. Once the unit is powered, the gateway shows at a glance when it is connected to the Polar Cloud, where the readings can be viewed. Insight you can act on From there, you can view live and historical readings on the Polar Cloud from a phone or computer. Knowing how a site is using power only matters if it changes what you do next. These readings show when your peak demand occurs, whether large loads start at the same time, and whether equipment runs after hours when it shouldn’t. If you roll out a new operating schedule or complete a maintenance fix, the historical log confirms whether it actually reduced your demand. The Power Cube doesn’t make those decisions for you, but it gives you the facts to make them. Built for safe installation A monitoring unit is only useful if it can be trusted, and that starts with safety. The Power Cube’s wall-mounted enclosure is rated IP54, and the voltage inputs are fused. The certifications cover the rest. The Lovato DMG7500 analyser carries CE, UKCA, and cETLus marks and conforms to IEC/EN 61010-1, the safety standard for electrical measuring equipment, so it meets recognised international safety requirements. The LTE gateway is ICASA-approved for use in South Africa and CE- and RoHS-certified. Local support from EM ElectroMechanica, Polar Monitoring’s authorised distributor, offers the Power Cube. We supply the complete solution: the Power Cube, CTs matched to your application, and the Polar Cloud licence, with local technical support to help you select the right product.

Tasty Gallos signs BP deal as fuel retailers look beyond the pump for profits F uel station dealers are under growing pressure to generate more income from food and convenience retail Muhammed Gutta, founder and CEO of Tasty Gallos, notes that dealers in these QSR partnerships can earn more from existing forecourt traffic and attract customers who
more important. Consumers increasingly stop at stations for reasons beyond refuelling, with around 68% buying fast food. This behaviour is unlikely to be temporary, with 75% of customers indicating they expect to maintain or even increase their visits to fuel stations. Food is key to forecourt economics The commercial appeal of QSRs has therefore gained further momentum. A restaurant that offers motorists a high-quality meal they enjoy gives them a reason to favour one forecourt over another, while creating a valuable source of non-fuel trade for the dealer. “Chicken is already a familiar part of how South Africans eat on the go, so Tasty Gallos’s offering translates naturally into a forecourt environment. Our flame- grilled and fried chicken gets its bold flavour from our unique blend of sauces and spices, developed to make every bite unmistakably Tasty. In a forecourt setting, that gives customers a compelling reason to stop, spend more time on the site, and potentially spend across the broader convenience offering,” adds Gutta. “For example, a customer stopping for a meal may add drinks, snacks, or other essentials from the adjoining shop. Meeting more of those needs under one roof creates more opportunities to earn from each customer visit.” Building on the BP relationship Tasty Gallos is engaging with BP dealers and fuel station operators to identify suitable partners for its forecourt expansion across South Africa. “We’re looking for operators who see the restaurant as a business worth building and are prepared to take an active role in its success. Our name goes above the door, so we care deeply about who’s running it. The dealer also has to want the restaurant to succeed just as much as we do, because they’re the one driving business on the ground.” Tasty Gallos has an established presence in major shopping centres, including Eastgate, Greenstone, The Glen, and Mthatha Plaza in the Eastern Cape, and recently opened a new location at the University of the Witwatersrand, with further expansion plans already underway.
restaurant gives the dealer a chance to bring that customer onto the site between fuel purchases and build more regular trade,” he says. Notably, research published by the Fuel Retailers’ Association in June this year found that fuel volumes had declined by 6.3% over the previous year, while fuel sales fell by 4.2% in 2024. Historically, around 90% of a fuel station’s income came from fuel sales, but it projects that this could fall to as little as 20% as forecourts evolve and other revenue streams become
as higher fuel prices and tight margins squeeze their bottom lines. Tasty Gallos’s new partnership with BP Southern Africa speaks directly to this challenge, allowing participating dealers to add a new source of non-fuel revenue by adding a home-grown chicken franchise to their forecourt offering. Consumer strain has intensified again this month, with petrol and diesel prices rising by more than R3 a litre. In total, motorists now pay over R9 per litre more for fuel than at the beginning of the year, giving them a stronger incentive to consolidate trips and favour forecourts that meet more than one need. For dealers, meanwhile, higher pump prices do not necessarily mean stronger returns, shifting the focus to earning more from each visit beyond the fuel sale itself. Against this backdrop, Tasty Gallos is provisionally targeting the second quarter of 2027 for its first BP quick service restaurant (QSR), subject to agreements being concluded with participating dealers.

to industrial facilities, critical systems must stay operational when the main power supply is interrupted. Whether the challenge is load shedding, an unexpected outage, or the need for dependable backup power, the right electrical infrastructure makes all the difference. In South Africa, power interruptions, network faults and supply constraints have made backup and alternative power solutions an important part of many electrical installations. Solar PV, batteries, inverters and generators can all provide alternative power, but a backup power source is only part of the solution. At MCE Electric, we supply a range of electrical products for solar PV, backup power, protection and distribution applications. These products help installers build systems that are safe, practical and reliable.
Together, these products form part of the infrastructure that helps keep power systems organised, protected and ready when the grid supply cannot be relied upon. Building a reliable power system There is no single backup-power solution that suits every installation. A small residential solar system has very different requirements from those of a commercial building, factory or larger emergency- power installation. Equipment must therefore be selected for the application. What remains the same is the importance of good system design and using the right equipment for the job. From DC isolation and PV string management to
circuit protection and power distribution, every component plays a role in keeping the system operating safely and reliably. MCE Electric continues to support the electrical industry with products for solar PV, backup power, circuit protection and electrical distribution. When the main supply goes off, you need to know the rest of the system is ready to do its job. Whether supporting a solar installation, a backup system or an emergency power solution, MCE Electric provides dependable electrical products for the systems that matter most. Because when the power goes out, reliability should never be left to chance.

infrastructure sits at an inflexion point. Load shedding has receded from daily headlines, but the underlying volatility it exposed - an ageing grid straining against rising demand - hasn’t gone anywhere. What’s changed is how the industry is responding: less panic-buying of diesel gensets, more engineered, data-driven power resilience. The standby power conversation has matured considerably. Where five years ago the default spec was “biggest genset that fits the budget,” installers are now designing layered resilience: UPS for critical loads with zero tolerance for interruption, battery energy storage systems (BESS) for medium-duration bridging, and generators reserved for extended outages. Automatic Standby, backup and emergency power transfer switches (ATS) with sub-cycle changeover times are now paired with remote monitoring platforms that flag failing batteries or fuel-level anomalies before they become emergencies. For SANS 10142-1 compliant installs, correct changeover switching and earthing configuration remain non-negotiable - but increasingly, that compliance is being verified through IoT sensors rather than a technician’s clipboard.

That’s where a wholesale partner matters: the right inverter, storage, protection and cabling, on the shelf at a branch near the job. That is what keeps a smart system on schedule. Lighting LED retrofit has largely won the efficiency argument on lumens-per-watt; the frontier now is intelligence. DALI-2 and Zigbee-based lighting control allow granular zoning, daylight harvesting and occupancy-based dimming that can cut lighting energy consumption in commercial buildings by well over half. Smart lighting is also becoming a data source in its own right - occupancy sensors feeding building management systems for space utilisation analytics, not just switching lights on and off. For electrical contractors, this shifts lighting projects from a supply- and-install job to a systems-integration one, requiring familiarity with protocols and commissioning software alongside traditional wiring skills.

Beyond basic backup: The evolving role of energy resilience in South Africa
Advanced storage integration: Replacing diesel generators with high-capacity UPS systems | By Minx Avrabos D emand for resilient, sustainable power infrastructure is driving a transformative shift in energy system grid-scale installations. PV solar integration Photovoltaic (PV) solar technology has
balancing initial investment with long- term savings and reliability. For example, a shopping centre or manufacturing plant may now deploy a hybrid system that draws on solar during the day, batteries during peak tariffs or outages, and only resorts to generators as a last line of defence. Cost optimisation and smart control Energy costs in South Africa are escalating, making it imperative for contractors to help clients control and predict their energy spend. Advanced energy management systems can monitor consumption patterns, shift loads to off-peak periods, and optimise the use of stored or generated energy. Combined with demand response strategies and remote monitoring, these tools help clients avoid costly demand charges and maximise returns on their energy investments. Sustainability is no longer a “nice-to-have” but a competitive necessity for South African businesses. Clients increasingly expect contractors to offer low-carbon solutions that minimise environmental impact. Integrating renewables and efficient storage not only reduces emissions but can also improve a business’s reputation and attract sustainability-conscious customers and investors. Sustainability: A competitive advantage Conclusion For electrical contractors, the future lies beyond basic backup. Those who embrace this evolution and deliver resilient, cost- effective, and sustainable energy solutions will be best placed to meet the complex demands of South Africa’s power-hungry economy.
By Minx Avrabos I n South Africa’s ever-changing energy landscape, electrical contractors are undergoing a profound transformation. Traditionally, they focused on standard backup power solutions, such as standby generators and simple uninterruptible power supply (UPS) systems, to safeguard critical loads during outages. But as the nation faces rising electricity costs, persistent load-shedding, and increasing pressure to embrace green energy, contractors are pivoting from basic backup to holistic, long-term energy resilience, cost optimisation, and sustainability. The shift: More than keeping the lights on While backup power remains essential, clients now demand solutions that not only keep operations running during outages but also optimise energy use and reduce dependence on the grid. Contractors are now expected to design and implement systems that ensure long-term operational continuity, manage rising energy expenses, and contribute to broader sustainability goals. This shift is driven by both economic necessity and a growing awareness of the environmental impact of traditional diesel- powered backup systems. Integrated energy solutions: The new standard Modern energy resilience is about creating integrated solutions that combine renewable generation (such as solar PV), advanced battery storage, intelligent energy management systems, and, where necessary, backup generators. These solutions are tailored to each client’s unique operational profile and risk tolerance,
design. Traditionally, diesel generators have provided backup and prime power for critical facilities. However, the landscape is rapidly evolving as organisations seek to reduce emissions, optimise operational costs, and increase energy reliability. This evolution is driven by the integration of advanced storage technologies—particularly large- scale battery storage, photovoltaic (PV) solar systems, and high-capacity Uninterruptible Power Supply (UPS) ecosystems—either alongside or in place of legacy diesel generator setups. The limitations of diesel generators Diesel generators are reliable but have several drawbacks. They are associated with high fuel and maintenance costs, noise pollution, and significant carbon emissions. Moreover, the reliance on fuel supply chains exposes operations to potential disruptions. As sustainability targets tighten, these limitations have prompted exploration of alternative solutions. Large-scale battery storage solutions Modern battery storage systems, such as lithium-ion and flow batteries, provide robust energy storage with rapid response times. At scale, these batteries can supply power during outages, smooth demand peaks, and store excess energy from renewables. Unlike diesel generators, batteries operate silently and emit no local pollutants. Their modularity and scalability allow for tailored deployment, from small commercial sites to large data centres and
matured enough to serve as a viable primary or supplementary energy source. Integrating PV with battery storage creates a hybrid system that can generate and store clean energy on-site. During daylight hours, solar panels can power operations and charge batteries. When sunlight is unavailable, stored energy is dispatched, reducing the need to run diesel generators or draw from the grid. This model improves energy autonomy and lowers operating costs by leveraging renewable generation. High-capacity UPS ecosystems High-capacity UPS systems are designed to deliver instantaneous, high-quality power to critical loads. Advanced UPS architectures now incorporate lithium-ion batteries and intelligent energy management, extending their role beyond mere power conditioning and short-term backup. In hybrid configurations, UPS units can integrate battery storage and PV systems, orchestrating seamless transitions between power sources and enabling longer outage coverage. Conclusion: toward smarter, greener energy systems Combining advanced technologies is reshaping power-system resilience and sustainability. Battery storage, solar PV, and sophisticated UPS systems offer alternatives to diesel generators. As they become more affordable and mature, organisations can sustain operations, cut emissions, and adapt to changing energy needs.

The hybridisation of emergency infrastructure: Integrating EPSS with DERs By Minx Avrabos I n recent years, the reliability and resilience of emergency power supply systems (EPSS) have become this transformation is the hybridisation of EPSS and DERs, requiring contractors and engineers to master the complexities of true hybrid systems.
When executed properly, hybrid emergency power systems deliver significant benefits. DERs such as solar and batteries can reduce generator runtime, lowering fuel consumption and emissions.
paramount for critical infrastructure such as hospitals, data centres, and municipal facilities. Traditionally, EPSS have relied on centralised backup generators, most commonly diesel-powered, to provide essential electricity during grid outages. However, the rapid evolution of distributed energy resources (DERs), including solar photovoltaics, battery energy storage, and microgrids, is reshaping emergency infrastructure. The core conversation in
Understanding the hybrid approach A hybrid emergency power system is not simply a parallel deployment of generators and DERs. Instead, it integrates centralised backup systems with decentralised energy assets. These systems rely on seamless coordination between conventional generators, renewable sources, and storage, managed by advanced control systems. This hybridisation aims to maximise reliability, optimise fuel use, reduce emissions, and

provide greater operational flexibility.
Key engineering challenges For contractors, the transition from standalone EPSS to hybridised systems demands a deep understanding of both legacy and modern technologies. Key engineering challenges include: Load prioritisation and switching: Hybrid systems must automatically prioritise critical loads and orchestrate smooth transitions between grid, generator, and DER power, often within seconds. Synchronisation and power quality: Integrating DERs with rotating machines (like diesel gensets) requires precise synchronisation and voltage/frequency regulation to avoid power quality issues. Control integration: Advanced energy management systems (EMS) are essential to coordinate dispatch, monitor system health, and respond to dynamic conditions such as fluctuating renewable output or fuel shortages. Regulatory compliance: Hybrid solutions must meet codes like NFPA 110 and IEEE 1547, requiring careful design and
Benefits of hybridisation When executed properly, hybrid emergency power systems deliver significant benefits. DERs such as solar and batteries can reduce generator runtime, lowering fuel consumption and emissions. Storage assets can provide instant ride-through during transfer events, while renewables can maintain essential loads for extended outages. Moreover, hybrid systems offer future-proofing, enabling facilities to adapt to evolving energy landscapes. Conclusion Hybridising emergency infrastructure is more than a technological upgrade; it is a paradigm shift in how critical facilities ensure resilience. For contractors, mastering the engineering behind true hybrid systems is essential to deliver robust, compliant, and sustainable solutions that meet the demands of a modern, distributed energy world.

the medium-voltage (MV) range, typically defined as 1kV to 36kV.
By Minx Avrabos C orporate and industrial campuses increasingly rely on dependable power to sustain mission-critical operations and high-tech infrastructure. As these facilities grow, the need for robust backup capacity has surged, prompting contractors and facility engineers to rethink conventional emergency power systems. This shift is reshaping grid interconnection and substation strategies, especially as emergency distribution extends further into
The growing need for MV backup Traditionally, campus backup power distribution relied heavily on low-voltage (LV) systems (below 1kV), often limited to localised generator sets and uninterruptible power supplies (UPS). However, the scale and complexity of modern campuses, such as research parks, data centres, and advanced manufacturing hubs, demand backup solutions that can support entire
sensitive equipment. Grid code compliance: Interconnection schemes must follow local regulations on protection, synchronisation, and islanding. Substation design innovations MV substations serving as emergency distribution hubs are now more modular, scalable, and intelligent. Innovations include: Prefabricated modular substations: These allow rapid deployment and easy scaling as campus needs evolve. Digital substations: Integrating digital sensors and communications improves real-time visibility and remote control. Enhanced protection: Advanced relays and arc-flash protection improve personnel safety and system reliability. Conclusion The push for greater reliability and resilience is transforming how corporate and industrial campuses approach emergency power. By extending backup capacity into the MV domain, organisations can ensure seamless operations, even during grid disturbances. Modern MV grid interconnection and substation strategies are central to this evolution, providing the scalability, flexibility, and intelligence that future- ready campuses require.
buildings or even campus-wide operations. This has led to the adoption of MV emergency distribution, which offers several key advantages: Wider coverage: MV systems can transmit power over longer distances with reduced losses, making them ideal for sprawling campuses. Higher capacity: MV substations and distribution can handle larger loads, accommodating the increased energy requirements of contemporary facilities. Flexible integration: MV infrastructure supports integration with distributed energy resources (DERs) like solar, battery storage, and microgrids, enhancing resilience. Strategic grid interconnection A critical aspect of MV backup deployment is the grid interconnection strategy. Modern substations are designed as nodes that can dynamically switch between utility feeds, on- site generation, and energy storage. This is typically achieved via automated switchgear, real-time monitoring, and advanced protection relays. Key considerations include: Redundancy: Dual or multiple feeders minimise the risk of single-point failures. Fast transfer switching: Automated systems enable seamless transition between grid and backup sources without interrupting

BESS can store surplus solar energy for use during peak evening demand and help stabilise the grid, allowing solar projects to deliver a more consistent supply that meets customers’ needs. To accommodate growing renewable generation, South Africa must invest in additional transmission lines, stronger substations, and increased transformer capacity. Modern grid controls and equipment are required to maintain stability, while streamlined approvals and coordinated investment will accelerate adoption. The growth of solar power presents substantial opportunities for the local electrical, engineering, and energy sectors. Projects such as Lion Thorn require a skilled workforce for construction, operation, and maintenance. There are also expanding prospects for local contractors, engineers, equipment suppliers, and technical service providers.
