TESS Electrical Sales & Service
TESS Electrical Sales & Service specializes in marine electrical engineering, automation, and component supply for boats, superyachts, cruise ships, and commercial vessels. Operating from hubs in South Florida and Barcelona, the company provides technical support, system modernization, and electrical troubleshooting to ensure long-term vessel reliability.
The company designs, tests, and modernizes core power infrastructure, focusing on generator power management, synchronization, and marine switchboard refits. Technical capabilities include Schneider Electric breaker upgrades, battery load testing, Megger insulation resistance testing, and the integration of WAGO PLC control systems. Rather than patching legacy setups, the company redesigns obsolete electrical architectures to establish standardized, serviceable configurations.
Through a strategic partnership with RH Marine, TESS Electrical Sales & Service implements and maintains the Rhodium automation and alarm monitoring platform. The company also engineers and integrates comprehensive vessel systems, featuring Magnus shore power converters, Vega tank sensors, Tyco and Consilium marine fire alarms, and class-approved IEEE cabling.
To prevent procurement delays during refit windows, the company maintains an extensive inventory of European electrical components and hardware. The stock includes specialized products from international manufacturers such as ABB, Merlin Gerin, Telemecanique, Mastervolt, Victron, Vimar, Roxtec, Phoenix Contact, Northstar, and Rittal.
