S.J. Andrews Electronics (PTY) LTD — Electronics Manufacturer, Inverters and UPS

Situated in Johannesburg, Gauteng, S.J. Andrews Electronics operates as a comprehensive electronics partner for businesses seeking design, development, manufacture and supply of power electronic solutions. The organisation positions itself as a full-spectrum provider, spanning component supply, bespoke design and engineering, and customised manufacturing—catering to a diverse mix of industries and application areas. The focus is on delivering practical power and energy solutions rather than merely handling routine hardware movements.

The company describes a threefold service offering that underpins its value proposition in the inverters and UPS segment. First, Supply covers a broad portfolio of batteries across multiple chemistries and form factors, inverters, chargers, and a range of home and commercial power backup and solar products. The breadth of products is designed to support typical power needs—from residential back-up power to industrial-scale energy storage. The inclusion of lighting, accessories, and related peripherals signals an integrated approach that can support both new installations and upgrades to existing systems.

Second, the Design & Develop capability focuses on creating customised solutions for power and energy requirements. The emphasis is on collaborating with clients from the design stage through to implementation. This suggests a consultative process where electrical and energy engineers work with customers to tailor an optimal solution, balancing performance, cost and reliability for specific use cases. The company invites customers to engage with its experts to discuss individual needs, underscoring a engineering-centred approach rather than off-the-shelf procurement alone.

Third, the Manufacture element indicates in-house production capacity for specialised electronic products on bespoke order. Examples include customised transformers and other purpose-built components. By offering manufacturing services, S.J. Andrews positions itself as a partner capable of delivering tailored electronic parts and systems aligned with client specifications, rather than merely distributing standard items.

The company highlights its broad focus across multiple sectors, noting extensive experience in medical, energy and renewable energy, mining, security, distribution and retail, manufacturing, commercial and residential contexts, as well as agriculture, construction and telecommunications. This portfolio demonstrates a capacity to support both high-availability and mission-critical environments, with an emphasis on not merely moving stock but providing high levels of customer support throughout the lifecycle of a project.

In addition to its core services, S.J. Andrews operates as a regional distributor and solution partner, emphasising South Africa-wide relevance. The business emphasises scalable and resilient power solutions designed to help clients mitigate tariff volatility and energy constraints. Recent communications point to a strategic role in the South African market, including distribution activity around advanced storage systems that align with Eskom tariff considerations and energy independence goals.

Typical engagements described by the company involve collaboration on custom power and energy hardware, including inverters, UPS, energy storage, and related peripherals. Projects may span design through installation, with potential continued support and refinement as systems scale or evolve to meet changing requirements. The integration of both supply and manufacturing capabilities supports clients seeking end-to-end accountability for both components and the final assembled solutions.

Practical considerations for customers looking to engage S.J. Andrews include planning around the lifecycle of an energy project. Early-stage design discussions can help identify the most appropriate battery chemistries, inverter ratings, and storage configurations. A one-stop approach—in which components, custom parts and system integration are coordinated by a single supplier—can streamline procurement, installation and ongoing maintenance. Given the breadth of sectors served, clients are advised to articulate their operational duties, peak loads and resilience requirements to ensure the final solution is robust and scalable.

• Main services offered: supply of batteries, inverters, chargers, and power backup products; design and development for customised power solutions; and in-house manufacture of specialised electronic components.
• Typical job types: bespoke energy storage and inverter installations for residential, commercial and industrial settings; design-led projects for mining, healthcare, security and manufacturing sectors; and customised transformer or electronic component manufacture on request.
• How requests usually work: initial consultation with experts to discuss needs, followed by design planning, prototyping or specification finalisation, and then implementation or manufacturing of the tailored solution.
