Marine electrical systems provide the power, distribution, and protection that keep every onboard system operating safely and reliably. At Berthon Spain, we deliver specialist marine electrical services focused on the design, installation, upgrade, and long-term integrity of yacht electrical infrastructure.
We work across AC and DC electrical systems, ensuring that power generation, storage, and distribution are correctly specified for the vessel’s operational profile. From generators and battery banks to inverters, chargers, cabling, and switchgear, every system is planned to meet real onboard demand, not theoretical load figures.
Our marine electricians support new builds, refits, and fault diagnosis, with particular attention to system documentation, labelling, and compliance. Clear schematics and structured installations are essential for safe operation, future servicing, and rapid troubleshooting at sea.
Marine electrical systems form the foundation on which navigation, communication, and control technologies depend. Our electrical team works in close coordination with Berthon Spain’s yacht electronics specialists to ensure that power delivery, system protection, and redundancy fully support all onboard electronic systems.
A yacht’s electrical system must deliver consistent power under variable load conditions, often for extended periods. We design and maintain electrical systems that prioritise stability, efficiency, and safety, even as onboard equipment and usage evolve.
Our services include generator integration, battery system upgrades, energy management, AC/DC distribution, and fault finding. Each installation is carried out with long-term reliability in mind, ensuring that electrical infrastructure remains robust, accessible, and serviceable throughout the yacht’s lifecycle.
Battery systems provide stored electrical energy for onboard operation. At Berthon Spain, we design and install battery systems that deliver reliable capacity and predictable performance.
We work with Lead Acid, AGM, Gel, and Lithium batteries, selecting the appropriate technology based on usage, charging cycles, and operational demand. Battery bank design focuses on correct sizing, layout, and integration to ensure efficient energy storage.
Capacity and lifecycle planning reduce premature wear and support long-term reliability. Upgrade and replacement strategies improve performance and efficiency while minimising disruption.

AC and DC electrical distribution systems deliver power safely and consistently throughout a yacht. At Berthon Spain, we design and maintain electrical distribution systems that prioritise safety, reliability, and clarity.
We configure AC and DC circuits to suit onboard loads and operational use. Cabling and protection are specified and installed to reduce voltage drop, prevent faults, and support long-term system integrity.
Switchgear and distribution panels are arranged for clear system control and safe isolation. Careful system separation and safety planning reduces risk, improves fault diagnosis, and ensures electrical systems remain stable under varying load conditions.
Power management and protection systems control electrical load and safeguard onboard infrastructure. At Berthon Spain, we design and maintain electrical systems that manage demand, monitor performance, and protect against faults.
Power management systems balance load and prioritise critical circuits. Electrical monitoring provides clear visibility of system status, helping identify irregularities early.
Protection devices such as breakers, fuses, and isolation systems are specified to limit damage and maintain safety. Effective fault prevention reduces downtime, protects equipment, and supports reliable long-term operation.
Marine electrician services focus on fault diagnosis, safe wiring, and long-term system reliability. At Berthon Spain, our electricians identify, correct, and upgrade electrical systems with precision and clarity.
We carry out electrical fault diagnosis to locate and resolve issues efficiently. Rewiring and upgrades are completed to improve safety, performance, and serviceability as onboard systems evolve.
Accurate system documentation, including clear labelling and schematics, ensures that electrical installations remain understandable, maintainable, and safe for future servicing.
Electrical refits modernise onboard systems while maintaining safety and reliability. At Berthon Spain, we deliver electrical upgrades that integrate cleanly with existing infrastructure.
We manage electrical refits and upgrades to improve performance and capacity without unnecessary complexity. Careful integration with existing systems preserves system logic and reduces risk during installation.
All work is planned to maintain compliance during refits, with accurate documentation and safe installation standards. Projects are scheduled to minimise downtime, allowing vessels to return to service efficiently.
Marine electrical systems provide the power, distribution, and protection that enable onboard electronics to function safely and consistently. While electrical infrastructure focuses on generation, storage, and distribution, electronic systems handle navigation, communication, monitoring, and control.
These technologies are delivered as complementary but distinct services at Berthon Spain. For navigation equipment, onboard connectivity, monitoring platforms, and integrated control systems, see our Yacht Electronics Services page.
Berthon Spain provides marine electrical services built on technical expertise and practical yacht experience. Our electricians deliver reliable solutions across new installations, upgrades, and fault-led work.
We apply yacht-specific experience to ensure electrical systems are designed for real operating conditions. Clear documentation and standards support safe operation, compliance, and future servicing.
Our approach emphasises long-term service support, ensuring electrical systems remain dependable and maintainable throughout the yacht’s lifecycle.
