Home energy, engineered for real life
Rafferty & Black Industries is a one-person UK science and engineering lab building practical, DC-native energy hardware for homes and off-grid communities. Most modern devices run on DC internally, yet we still convert AC→DC repeatedly, wasting energy and adding failure points. Our R&D focuses on a modular DC “bus” backbone that sits between renewables (solar/battery) and loads, with protection, controlled connection/inrush, and plug-in power modules. We build constraints-first, instrument everything, publish what we learn, and iterate toward a robust UK-made platform..

First-principles engineering for DC-native power
Our foundation is built on first principles, developing DC-native renewable power modules that drastically reduce energy conversion losses. This innovative approach simplifies maintenance, bolsters safety, and makes off-grid and standard home energy systems exceptionally reliable and scalable. We focus on practical, human-facing technology, designed in the UK, to empower individuals and communities with robust, efficient energy solutions that truly matter.

Powering progress together
Are you driven to shape the future of energy? We are actively seeking visionary funders to propel our research, and pilot partners—from off-grid communities to innovative homeowners—to test our prototypes in real-world conditions. For engineers in the UK looking to contribute, we welcome volunteers eager to apply their skills, gain invaluable experience, and even leverage it for universal credit claims. Connect with Rafferty & Black Industries and be a part of this transformative journey.

Demonstrating real-world impact
Transparency and tangible results are at the core of our development. As our technology evolves, we will share compelling videos, detailed images, and comprehensive data showcasing its real-world performance. You’ll be able to see the measurable differences in cost savings, efficiency improvements, and reduced household energy consumption. We are committed to providing clear, evidence-based insights into how our innovations are making a practical, positive impact on energy independence and sustainability.
