What Black Stump Technologies does

Black Stump Technologies Pty Ltd is an Australian private hardware-and-services company founded in 2017 (spun out of an engineering business originating in 1970) that designs, manufactures, sells, and rents the Solarator product line — mobile, modular, rapidly deployable power and cold-chain systems engineered to replace diesel generators in off-grid and temporary worksite applications. The core technology is a proprietary triple-redundant hybrid architecture combining solar PV, battery storage, and a bio-diesel backup generator, orchestrated by the company's own Battery and Energy Management System (BEMS). The portfolio spans Solarator Mini (12+ kVA), Compact (25+ to 150+ kVA), Fold-Out (50+ to 75+ kVA), Microgrid and Mobile Solar Farm Arrays (200-500+ kVA, megawatt-capable), Office and Grid Connect variants for power generation, and Solarator Ice, Chill, Freeze, and Flat Pack units for off-grid cold chain. All deployed units feed a cloud-connected custom reporting portal that delivers fuel-cost, CO2, and ESG reporting to the customer.

The company serves enterprise and government customers across infrastructure and construction (Transport for NSW, Gamuda Australia, McConnell Dowell, BMD Group, AECOM, Symal Group), mining and resources (BCI Minerals), defence (Department of Defence Science and Technology Group), aid and development (DFAT-funded ANGAU Memorial Hospital mortuary in PNG, Vanuatu DARD), and remote and off-grid hospitality (Coconut Club, Bahamas), with deployment footprint across Australia, Spain, Papua New Guinea, Vanuatu, the Bahamas, Djibouti, and the USA. Revenue is generated through hardware sales, equipment rentals, recurring service and maintenance plans, and subscription-style access to the custom reporting portal, with quote-based custom pricing on multi-year contracts determined by an evidence-based sizing methodology. Distribution is direct, supported by a partner-led deployment model in which tier-1 construction contractors specify and deploy Solarator on their own infrastructure projects, and a new August 2025 partnership with Watahan Solutions extends geographic reach.
