Green Voltage

Green Voltage is a British power equipment hire company specialising in silent, zero-emission battery power systems for film, television and event production. It was founded in October 2018 by David Sinfield and Adam Baker, two film industry professionals whose combined credits span more than 90 productions including Bond, Star Wars, Indiana Jones, La La Land and major projects for Marvel, DC and Disney. While working together on Wonder Woman 1984, they observed a contradiction at the heart of their industry: a sector increasingly conscious of its environmental impact was still relying heavily on large diesel generators, often running for hours at partial load. Green Voltage was created to bring practical, quieter and cleaner energy solutions to production environments. The company positions itself not merely as a provider of cleaner power but as a supplier of the right tool for the job. Its flagship product is the GV Kube 10k, a battery power unit designed, engineered and assembled in Britain. The unit delivers 6 kVA of continuous output and 10.2 kWh of usable capacity, with a typical recharge time of 1.5 hours. It uses LiFePO₄ (lithium iron phosphate) chemistry and includes integrated 4G telemetry and parallel-link scaling, allowing multiple units to be combined for larger power demands. Green Voltage markets the system on the benefits production teams care about: silent operation that allows power to be placed closer to set, cleaner operation, faster turnaround and live visibility of system status, all without the compromises associated with diesel. Green Voltage serves the film, TV and events markets in the United Kingdom, offering battery hire as well as purchase information. The company has built its reputation on being trusted on major productions and on developing, testing and refining mobile power approaches specifically for production environments rather than generic site use. Its contact channels include a quote request route and a sales line. As a privately held specialist, it operates in the growing niche of sustainable on-set power, where the shift away from diesel generators is driven by both environmental targets and the practical demands of noise-sensitive filming locations.

Green Voltage was founded in October 2018 by David Sinfield and Adam Baker, two film industry professionals with more than 90 combined credits across Bond, Star Wars, Indiana Jones, La La Land, and major projects for Marvel, DC and Disney. The idea took shape while the pair were working together on Wonder Woman 1984, where they saw a clear contradiction: an industry increasingly aware of its environmental impact was still relying heavily on large diesel generators, often running for hours at partial load. They founded Green Voltage with the goal of bringing practical, quieter, cleaner energy solutions to film and television production. Since its founding, the company has tested, refined and developed new approaches to mobile power, establishing itself as a specialist in silent battery systems for production environments. Its flagship product, the GV Kube 10k, is a battery power unit designed, engineered and assembled in Britain. It delivers 6 kVA of continuous output and 10.2 kWh of usable capacity, with a typical recharge time of 1.5 hours, LiFePO₄ chemistry, integrated 4G telemetry and parallel-link scaling. Green Voltage markets the system on silent operation, cleaner operation, faster turnaround and live visibility, positioning it as the right tool for the job rather than just cleaner power. The company offers battery hire and purchase information for film, TV and events in the United Kingdom, and states that it is trusted on major productions.
