Onboard Solar Launches Dedicated Electrical & Electronic Services for Canal Boats
Trusted electrical engineers for narrowboats, widebeams and Dutch barges across the UK
Onboard Solar is pleased to announce the launch of its specialist canal and inland waterway electrical & electronic services, supporting narrowboats, widebeams and Dutch barges throughout the UK.
Already known for reliable off-grid solar systems, Onboard Solar now offers a full suite of professional marine electrical services, covering fault-finding, repairs, upgrades and complete electrical refits — all delivered by experienced marine engineers who understand the realities of life on the water.
When boat electrics are working properly, everything feels easier. Charging becomes predictable, power is stable, and unexpected faults don’t ruin weekends or cruising plans. Onboard Solar’s approach focuses on safe wiring, tidy installations, sensible component choices and real-world reliability, ensuring systems are built to work day after day, not just look good on paper.
Built for Canal & Inland Waterway Boats
Unlike general electricians, Onboard Solar specialises in the unique demands of inland boats. Systems are designed and installed with vibration, moisture, limited space and mixed charging sources in mind — helping boat owners avoid common issues such as premature battery failure, nuisance trips and unreliable power.
Whether customers are upgrading a single component or planning a full electrical overhaul, Onboard Solar provides clear advice, quality workmanship and solutions that make sense for how boats are actually used.
Electrical Fault-Finding & Repairs
Electrical problems can be frustrating, intermittent and difficult to trace. Onboard Solar offers thorough diagnostics to identify issues such as voltage drop, charging faults, heat damage, nuisance RCD/MCB trips, poor connections and so-called “mystery drains”.
Rather than guessing, engineers provide a clear explanation of the fault and a proper repair, restoring confidence in the system.

Battery Banks & Battery Monitoring
From battery replacements to complete bank redesigns, Onboard Solar helps customers improve runtime and reliability. Services include battery bank balancing, monitor installation and configuration, and correcting cabling and fuse protection.
The result is predictable energy storage and accurate state-of-charge information, so owners know exactly what power they have available.

Charging Systems: Alternator, Solar & Shore Power
Many onboard issues stem from poorly regulated charging. Onboard Solar improves charging performance across alternator, solar and shore power systems, ensuring batteries are protected and charged correctly.
This service is ideal for slow charging, over- or under-charging concerns, mixed charging sources and seasonal solar optimisation — delivering faster, safer charging and longer battery life.

Inverters, 230V AC Systems & Shore Power
Adding or upgrading mains power onboard requires careful design. Onboard Solar supplies and installs inverters, upgrades consumer units, implements correct earthing and bonding strategies, and integrates shore power safely.
The outcome is stable, properly installed AC power that improves safety, reduces nuisance trips and supports everyday onboard living.

DC Distribution, Fusing & Cable Upgrades
Many boats suffer from years of add-ons and temporary fixes. Onboard Solar rebuilds untidy DC systems with proper fuse protection, busbars, isolators, labelled circuits and neatly routed looms.
This results in a safe, serviceable electrical system that current and future engineers can work on with confidence.

Marine Electronics & Practical Upgrades
From LED lighting and pumps to switches, control panels and general 12V electronics, Onboard Solar modernises onboard systems to reduce power draw and improve usability.
Upgrades are selected for durability and practicality, delivering clean, dependable improvements that suit real cruising.

Onboard Solar now provides complete marine electrical and electronic services for canal boats across the UK — combining technical expertise with a practical, boat-owner-first approach.
