What Sterling Power does

Sterling Power Products Ltd is a UK-based private limited company (founded 2012, 11-50 employees, headquartered in Droitwich/Worcester) that manufactures power conversion and battery management hardware for marine, vehicle, and off-grid applications. Its product portfolio spans AC/DC battery chargers (Pro Charge Ultra, AQUA IP68, Aquanautic, UBC, AMPS), DC/DC battery-to-battery chargers, alternator-to-battery charging systems, high-powered alternators (12V-48V, 100A-300A), advanced alternator regulators, lithium battery systems (heated LH series, L series, AL series, LP performance, and 19-inch rack-mount), portable power stations, pure sine wave inverters, Bluetooth battery monitors, solar regulators and panels, EV chargers (22kW-180kW), mobile air conditioning, DC refrigeration, induction hobs, and galvanic isolators. The company's technical differentiation rests on proprietary Power Factor Correction (PFC up to 0.99 PF), synchronized MOSFET rectification, a custom alternator-to-battery voltage amplification architecture, the Alternator Linearisation Device (ALD), and 11 preset plus 1 custom charging algorithm. Products carry UL, CE, ABYC, and IP67/IP68 certifications for harsh-environment use.

Sterling Power operates a direct-to-consumer model through a Shopify-based storefront shipping to 38 countries, supplemented by a dedicated trade customer program for professional installers and resellers targeting marine, camper van/mobile, off-grid, and commercial fleet use cases. Its primary segments are marine/boat owners and vehicle/mobile power users (both marked as primary), with secondary segments in off-grid/remote power and professional trade installers. Revenue is generated through one-time hardware unit sales priced in GBP and other currencies, ranging from sub-£100 entry chargers to £3,500+ complete power systems. The company holds no disclosed funding, no parent organization, and no enterprise customer logos; its commercial moat rests on proprietary charging IP, an integrated product ecosystem, regulatory certifications, and broad global DTC plus trade distribution.
